Galileo receives Pro Audio Review Reviewer’s Pick Award
M’elodie receives Pick Hit award from Sound & Video Contractor Magazine
Constellation electroacoustic architecture launched at Zellerbach Hall
The VRAS variable room acoustic system fascinated John Meyer, who saw much potential for its use in multipurpose venues. When Meyer Sound acquired LCS Audio, VRAS was one of his strongest interests and a VRAS system had been installed in the company's Pearson Theatre.

Meyer envisioned the next step for the technology as being that customers who purchase a system would receive a turnkey system, a complete package of design and tuning services from trained specialists in acoustics and digital audio, as well as hardware components designed specifically for the needs of electroacoustic architecture. The tuning process underwent transformation to increase its efficiency and methods. The result of this holistic upgrade was dubbed "Constellation" by Grammy-winning classical music recording and live sound engineer John Pellowe, who became involved in its development.

The first Constellation system was installed into Zellerbach Hall, on the University of California Berkeley campus. Meyer Sound had a long association with Zellerbach, and the timing was perfect, as Zellerbach faced an acoustical challenge in the variety of program material on the bill of their upcoming centennial gala.

The system made a characteristically low-profile debut at the gala in Zellerbach Hall on May 12, 2006 and received enthusiastic responses. Constellation was now officially launched.
M’elodie ultracompact high-power curvilinear array loudspeaker
The MILO family had grown. The original MILO loudspeaker proved a major hit, especially for its smooth, extended high-frequency response, high-power, and easy-to-use QuickFly rigging. With M'elodie (named for John and Helen's granddaughter, Elodie, sister of Milo), Meyer Sound brought those qualities to package much smaller than MILO, in fact, smaller than the M2D. Like the larger MICA loudspeaker before it, M'elodie was fast out of the gate; a popular product from its introduction. With the addition of M'elodie, the MILO family line had a complete collection of sizes and coverage variations.
MICA receives MIPA Award for Best Large Format PA System
Having received its first MIPA Award only two years before, Meyer Sound quickly repeated the performance by winning a 2005 award for the MICA compact high-power curvilinear array loudspeaker. Attendees at the Frankfurt Musik Messe/Pro Light + Sound exposition, during which the awards are presented, went to the Meyer Sound booth to check out MICA and found the company also showing the brand new M'elodie loudspeaker for the first time in Europe.
2005
Galileo loudspeaker management system
While digital audio had been around for decades, it was not until the '90s that it started to mature, and it was only after the turn of the millennium that it began seriously penetrating sound reinforcement. It was obvious that digital audio was the future, offering capabilities that were simply not possible with analog audio, but John Meyer didn't want to get Meyer Sound seriously involved with digital audio until he felt it was possible to attain the level of quality he felt qualified as "good sound." Although Meyer Sound made the SIM analyzer, the RMS remote monitoring system, and MAPP Online acoustical prediction software, the company had never made a digital device that was part of the signal chain.

Finally, around 2004, he decided the time had come and Meyer Sound embarked on a collaboration with LCS Audio, a small company making a powerful, high-quality digital audio system for theatrical sound, on a new, all-digital system drive processor. The project was headed by Perrin Meyer, John and Helen's son and the company's software R&D manager. In late 2005, the Galileo 616 processor and Compass control software for it shipped to an audio world eager to see what Meyer Sound would do in its first foray into digital audio.

The Galileo system was a breakthrough in a number of respects, including the number of inputs and outputs, its fixed latency, and its Composite EQ, which allowed corrective equalization with a minimum of phase shift.

The fact that one of the very first units was installed at Carnegie Hall underscored both the industry's confidence in Meyer Sound and its enthusiasm for Galileo's features and performance.
Meyer Sound acquires LCS Audio
LCS Audio's history went back to 1992, when engineer Steve Ellison and sound designer Jonathan Deans formed Level Control Systems. In 1996, the company merged with John McMahon's Cadence Digital Audio and its product grew from a multichannel panning system into a complete theatrical digital audio system, needing only microphones and a loudspeaker system to provide sound for a production. While LCS Audio was a small company with a fanatical following amongst theatrical sound designers, it was hard-put to marshal the resources necessary to grow significantly.

Meyer Sound collaborated with LCS Audio in the creation of the Galileo loudspeaker management system, during which time it became evident that both companies could benefit by joining forces: Meyer Sound would gain an established, experienced, forward-looking digital audio team for its new initiative into that field, while LCS Audio would gain the benefit of Meyer Sound's greater resources and highly successful vision and methods.

The two companies had many similarities in their corporate philosophies and cultures, and even overlapping markets, which made the idea even more attractive. In late 2005, Meyer Sound acquired LCS Audio and took the next step down the path Galileo had established.
MICA receives Pro Audio Review PAR Excellence Award
Pro Audio Review Magazine has favored Meyer Sound with numerous favorable reviews over the years, as well as awards. The magazine clearly knew a good thing when it saw/heard it, and was the first to bestow an award onto the new MICA loudspeaker.
MVC-5 Ornamental Design of a Loudspeaker
Ornamental Design for a Microphone
This design patent is for the appearance (or "ornamental design") of a microphone created as part of a development project.
Frequency Dependent Excursion Limiter
There are several ways that applying too much power to a loudspeaker driver can cause it to fail. One is overheating of the voice coil. Another one is over-excursion: when the applied voltage causes the driver to try to move further than it is mechanically able. Vented enclosures are particularly susceptible to this, especially below the tuning frequency of the enclosure, where the acoustical impedance becomes very low.

There are several methods that are often tried for protecting against this. One is a standard limiter, but at the low frequencies of concern, they are often too slow when they need to be instantaneous. Further, very short attack times can sometimes produce artifacts. Another method is a high-pass filter, but they are not very effective and can introduce significant phase shifts that degrade the sound.

Frequency-dependent limiters are a third method that has been applied. The frequency-dependent limiter triggers limiting at different levels for different frequencies, in accordance with measurements of the loudspeaker taken during the development phase to determine the maximum allowable voltage at those frequencies. In most cases, these limiters were used in open loop systems (that is, without a controller receiving feedback from the loudspeaker) and, as a result, had to be quite complex, involving matched filters and other difficult circuitry.

This patent is for a greatly simplified circuit for a frequency-dependent limiter. Clever use of feed-forward and feedback circuits eliminates the need for matched filters. Other efficiencies are introduced by circuits that combine two functions that are separate in other frequency dependent excursion limiter designs. Overall, not only is the complexity of the circuit less, the parts count is also considerably reduced.

Also addressed in the patent is the use of the limiter in a closed-loop system such as Meyer Sound's self-powered loudspeakers.
Galileo wins Rental & Staging Award for Best Audio Control/Mixing Product
MILO Front of a Loudspeaker
This design patent covers the appearance (or "ornamental design") of the front of MILO. The design is patented to prevent other companies from creating confusion in consumers with a product that looks identical.
MICA compact high-power curvilinear array loudspeaker
MICA brought the essential qualities of the MILO loudspeaker to a smaller footprint that was nonetheless powerful enough to cover medium-sized venues on its own, or to augment a MILO main system as downfill or sidefill. Released at the beginning of the 2005 summer concert and festival season, MICA made a quick mark in the industry as a "go-to" box for all but the largest gigs. Orders were shipped in dizzying numbers from the first day of its release.

MICA's QuickFly rigging introduced captive GuideALinks, which greatly improved safety by eliminating the need to ever put hands or fingers between cabinets, as well as providing the convenience of links that were permanently mounted in the rigging frame.
MVC-5 graduated vertical coverage loudspeaker
The development of the MVC-5 technology was sparked by John Meyer's loudspeaker demonstration at an ashram in India. He was asked to provide the sound for one of the "small" morning services. He was allowed to provide the sound for one of the "small" morning services: about 35,000 worshippers gathered under a huge corrugated aluminum roof. He did the job with six arrays of six M1D loudspeakers each, placed strategically around the area.

Meyer realized that similar sound reinforcement scenarios were not uncommon: large, primarily flat spaces that needed even coverage best accomplished with a distributed system, such as a convention center or a church. The MVC-5 is actually a small line array in a single enclosure, with the splay angles fixed to yield graded vertical coverage, through which level stayed fairly constant as one moved towards the loudspeaker.
2004
MILO receives TEC Award for Outstanding Technical Achievement, Sound Reinforcement Loudspeaker Technology
Meyer Sound's fifth TEC Award went to MILO. The following year, the MILO 120 was nominated for the same award, with MICA garnering yet another nomination in 2006, continuing Meyer Sound's streak of at least one TEC nomination in nearly every year the awards have existed.
UPA-1 inducted into the TECnology Hall of Fame
The TECnology Hall of Fame was created by the Mix Foundation to recognize those products and people who had truly changed the face of the audio industry. Its first year of induction was 2004, and the UPA-1 was voted one of the first 25 inductees to the hall. John Meyer accepted the award and spoke about the UPA-1's creation. He received a standing ovation from the distinguished industry members in attendance.
Meyer Sound builds Pearson Theatre at its Berkeley headquarters
Meyer Sound's educational seminar series, which dated back to the original "SIM School" given by Bob McCarthy starting in 1984, had never had a real home in the company's hometown of Berkeley, Calif. By 2004, the educational program was expanding substantially, along with the company in general, and the use of a local hotel for seminars was no longer viable. Discussions began about building a training theatre at Meyer Sound, and the more it was talked about, the more potential uses for such a venue came to light.

The decision was made in Spring 2004 to proceed with construction….with a deadline of late October when the company wanted to show the theatre during the Audio Engineering Society convention in San Francisco, during which time it was also holding a celebration of the company's 25th anniversary. The race was on to get the theatre built, but it was complicated by constant adjustments to the design.

As the theatre is being designed and built, John Meyer formulates and puts into practice new ideas on the building of multipurpose spaces. Events of the time, such as Meyer Sound's participation in the "Mythbusters" TV show "Brown Note" episode, influenced aspects of the how the theatre is built.

In the nick of time, the beautiful 57-seat theatre is completed. The theatre's design and equipment are unique and, after the acquisition of LCS Audio in 2005, a VRAS system is installed, the first step in the formation of Constellation electroacoustic architecture. After the death of Don Pearson, the theatre is named the Pearson Theatre in his honor.

The 700-HP receives Pro Audio Review Magazine’s Reviewer’s Pick Award
After giving a more than enthusiastic review to the 700-HP, it was no surprise when Pro Audo Review's group of reviewers chose to award it a Reviewer's Pick Award.
Meyer Sound appears on “MythBusters” TV show
Meyer Sound products and personnel have appeared on several episodes of "MythBusters," the popular weekly television show appearing on the Discovery Channel. The quirky series, produced by Australia's Beyond Productions, combines hard science and wacky humor as its two hosts debunk or confirm various urban legends.

During the show's premiere season, "MythBusters" called on Meyer Sound Staff Scientist Dr. Roger Schwenke to confront the legend that a duck's quack doesn't echo. To debunk this myth, live duck quacks were recorded and analyzed in a meadow at a duck farm, in Meyer Sound's anechoic chamber, and in a large, empty warehouse.

Several months later the "MythBusters" team returned to Meyer Sound, recruiting both Schwenke and John Meyer to test a myth rather less suited to squeamish viewers: the so-called "Brown Note."

In yet another investigation, Schwenke was tapped a third time to help confront the myth that a wine glass can be broken by a singer producing the proper pitch. (It can.) This time, the "MythBusters" crew came to Meyer Sound's own Pearson Theatre to tape part of the sequence, which used a UPA-1P loudspeaker and a SIM 3 audio analyzer.
UPJ-1P receives Entertainment Design EDDY Award for “Sound Product of the Year”
SIM 3 receives InfoComm 2004 Pick Hit Award from Sound & Video Contractor
MILO 120 high-power expanded coverage curvilinear array loudspeaker
SIM 3 audio analyzer system
Built on almost 20 years of research and development, ongoing worldwide field testing and award-winning, breakthrough technology, the SIM 3 audio analyzer system is the next generation of acoustical audio analysis in an integrated hardware and software package. In the field or on the bench, the SIM 3 system analyzes entire sound systems as easily as it verifies the performance of individual electronic components. SIM 3 represents a major advance over previous versions of SIM, with greatly increased power and added features at a fraction of the original size and cost.
MILO receives MIPA Award for Best Large Format PA System
The mipa (Music Industry Press Association) Award is voted on by about five dozen major magazines from around the world and presented at the Frankfurt Musik Messe/Pro Light + Sound exposition. MILO was the first, but not only, Meyer Sound product to win this award.
2003
700-HP ultrahigh-power subwoofer
One of the first products ever made by Meyer Sound was the 650 subwoofer created for Francis Ford Coppola's "Apocalypse Now," and the 650's descendants, the 650-R2 and the self-powered 650-P, had become industry standards. By 2003, however, sound systems were considerably more high-powered than when those subwoofers were created. FOH mixer Lars Brogaard, having purchased a large MILO system, wanted a subwoofer to go with it that had more power than the 650-P.

After prototyping several different approaches, the 700-HP ultrahigh-power subwoofer was released in late 2003. The 700-HP had truly massive output (139 dB SPL max) and enough headroom it was nearly impossible to clip, yet very low distortion. The market responded enthusiastically and immediately, and the 700-HP replicated the success the 650-P had received years before.
M3D receives Producción Profesional and Producción Audio Award as Best Sound Reinforcement Product
Producción Profesional and Producción Audio are two of Spain's best respected trade magazines for entertainment technology. In 2003, they held their first awards ceremony in Madrid's Auditorio Sur de IFEMA. The M3D was recognized as one of the inaugural recipients of an award.
M2D receives Pro Audio Review Reviewer’s Pick Award
LD-3 compensating line driver
The eight-channel LD-3 line driver brings new capabilities to system drive processors. While it contains useful features like compensatory equalization for M Series arrays and subwoofer crossovers, the most distinctive attribute the LD-3 offers is its atmospheric compensation EQ. Feed environmental conditions into the LD-3 through its Temperature, Altitude and Relative Humidity knobs, dial-in the type of loudspeakers and throw for each section of the array, and the LD-3's RISC microcontroller retrieves response correction coefficients and uses them to apply equalization that compensates for the conditions. By utilizing multiple-variable atmospheric loss equations and pre-calculated MAPP Online stored values, the LD-3 deals with the non-linear air absorption variations caused by changing conditions.
M2D and M1D curvilinear array loudspeakers share Entertainment Design EDDY Award for Sound Product of the Year
Ever since the release of the original UPA-1, Meyer Sound loudspeakers had been synonymous with theatre, finding constant application in Broadway and West End productions, and in the increasingly numerous and elaborate productions in Las Vegas. The M2D and M1D were curvilinear array loudspeakers ideally sized for this market, which was moving quickly into the use of line arrays.

While the UPM-2P had won the hearts of the theatre community — and an EDDY award — for its brilliance in fill applications, the M1D and M2D did the same for main FOH systems, winning their own EDDY
X-10 Loudspeaker System with Feedback Control for Improved Bandwidth and Distortion Reduction
This patent, issued to the University of California and licensed by Meyer Sound, defines the servo system used in the X-10 high resolution linear control room monitor, technology borrowed from the avionics industry. The patent defines a system for improving frequency response (magnitude and phase) in the sub-bass region of 20 – 100 Hz. Linearity is extremely difficult to achieve in this region, mostly due to three factors: non-uniformity in the magnetic field surrounding the voice coil, voice coil self-inductance variations with cone position, and the non-linear spring behavior exhibited by the surround and spider.

The system described in the patent employs a microphone mounted in front of the low-frequency driver to acquire a pressure feedback signal from the drivers' audio output. This signal is then scaled and subtracted from the audio input signal (which is also scaled) to derive a difference signal. The difference signal is passed through a series of filters to generate a correction signal that is then applied to the loudspeaker.

By placing the microphone very close and off-axis to the speaker, the delay time in the feedback is minimized, room effects do not affect the servo mechanism and cone breakup mode effects at higher frequencies are minimized (simplifying the task of modeling the driver's behavior). The filter network generating the corrected signal can be implemented digitally or with analog circuitry.

The system offers advantages over other systems commonly applied to subwoofers in order to flatten response. One system applies an equalized signal to the driver, but the signal is fixed and is not derived from feedback on the system's operation, making it unable to compensate for modifying effects such as aging or environmental factors. Another system attaches an accelerometer to the voice coil, which adds mass to a critical component.
Mars assembly facility goes online
Since late 1983, all of Meyer Sound's loudspeakers had been built in the back half of its main building, now affectionately called "Earth." By the late '90s, production had grown to the point where that space was simply no longer viable. Over the course of the years, production personnel had plenty of time to form ideas about better ways the job could be done. John and Helen Meyer eventually decided to give them the chance to put those ideas into practice. Rather than bring in an outside consulting firm to design a new facility, the Meyers worked with Meyer Sound's production staff to fashion a place where loudspeakers could be built efficiently enough to meet the short turnaround times that were often required for tours and other customers with tight deadlines.

The Mars facility implements many simple, yet clever and effective ideas to streamline the assembly process while maintaining the extraordinary level of quality assurance for which Meyer Sound is known. The name followed in the tradition of planetary names established with the creation of the Saturn transducer fabrication facility.
UPJ-1P compact VariO loudspeaker
Meyer Sound has been involved in the fixed installation market since early in the company's history. As a source of revenue, installations had grown steadily over the years. While many products finding steady use in installations had originally been designed for touring and concert use, growth in the installation market made it clear that Meyer Sound should try the opposite approach and make a product for fixed installation that could also serve touring.

The UPJ-1P employed a rotatable horn, an idea that others had done, but with one very simple and important improvement: the UPJ-1P's horn was marked to give a visual indication of which orientation had the wide coverage angle! The other major feature aimed at the installation market was a broad variety of mounting options, from pole mounting to small arrays.

The installation market loved the UPJ-1P from its release….as did the touring market, which finds the UPJ-1P ideal for fill applications.
MILO high-power curvilinear array loudspeaker
MILO was Meyer Sound's second generation of self-powered loudspeakers leveraging the line array effect. A number of valuable lessons had been learned from building the M3D, M2D, and M1D, and these were combined with extensive customer feedback in the design of MILO.

Named for John and Helen Meyer's grandson, the MILO loudspeaker was much lighter than the M3D. It was also a four-way system, incorporating three two-inch diaphragm compression drivers dedicated to reproducing very high frequencies. The mid-high and very high-frequency sections used the latest versions of the patented REM manifold.

MILO was capable of very high output with low distortion and an extremely smooth, extended high-frequency response. It's QuickFly rigging was improved over the M3D rigging, but the cabinet was the same width so that it could easily be rigged with M3D-Sub directional subwoofers or M3D line array loudspeakers.

When the MILO was released, it took off like a rocket, winning both high sales and multiple awards. Though Meyer Sound's business was already on a strong upswing, MILO suddenly took things to another level altogether, starting a growth spurt that has yet to subside.
2002
M2D compact and M1D ultracompact
Meyer Sound followed the M3D with the introduction of the M2D compact curvilinear array loudspeaker, the M1D ultracompact curvilinear array loudspeaker, and their companion subwoofers (M2D-Sub and M1D-Sub). With those three models in the M Series, sound designers could create integrated systems using compatible line array products of all sizes, affording flexibility and consistent results in applications ranging from the smallest theaters or churches to the largest arenas or outdoor concerts.

After a few years, some clever M1D owners realized that they could be used outside of arrays: individual cabinets worked excellently for frontfill or under-balcony coverage. This usage of the M1D has now become commonplace.
Interconnectable Rigging System for Loudspeakers and Rigging Frames (patent 6,640,924)
The first patent for Meyer Sound's groundbreaking QuickFly rigging system used on the M3D, M3D-Sub, M2D and M2D-Sub.
REM Manifold for a Horn Loudspeaker
Meyer Sound applies for a patent for the REM ribbon emulation manifold waveguide, an innovative design at the heart of the mid- and high-frequency sections in Meyer Sound's line array and curvilinear array loudspeakers. The REM manifold's main advantages over other designs - lower distortion and tighter pattern control - are achieved due to its short length and exponentially increasing waveguide channels. The patent is granted in 2003.
2001
M3D line array loudspeaker
The self-powered M3D was Meyer Sound's first loudspeaker to employ the line source principle in a vertical format. (The M3D is an actual line array loudspeaker, intended to be used with little or no splay between cabinets, as opposed to the rest of the M Series products, which are designed for use in curvilinear arrays.)

While the M3D is extremely powerful and full-range, with a frequency response that goes down to 35 Hz and all the way up to 18 kHz, the real breakthroughs it exhibited came in other areas, most notably in the form of BroadbandQ technology.

Loudspeaker specifications often state horizontal coverage angles, but the reality is that horizontal coverage varies radically with frequency across the response of a full-range loudspeaker. The M3D combined two Meyer Sound advances to produce a loudspeaker that maintains a much more consistent horizontal coverage angle across its wide response.

In the low end, the directional steering technology first developed in the PSW-6 is employed to yield a cardioid coverage pattern. For the mid and high frequencies the M3D introduced the patented REM manifold, which lets high-output compression drivers deliver the kind of directional control associated with line sources. Together, these two advances comprised BroadbandQ.
UPM-2P receives Entertainment Design EDDY Award for Sound Product of the Year
Sponsored by Entertainment Design Magazine (now Live Design), the annual EDDY Awards honor outstanding contributions in the field of entertainment design and technology. In the 10th anniversary year of the EDDY awards, the UPM-2P wins Sound Product of the Year. The judges call the UPM-2P "the directional UPM we've all been asking for," and comment that "It's small, but it sounds great and it packs a punch," concluding "It's a great product because, as usual, Meyer did it right."
MAPP Online multipurpose acoustical prediction program
MAPP Online is a powerful, cross-platform, application that accurately predicts many aspects of how Meyer Sound loudspeakers will perform in a user-defined scenario, including coverage pattern, frequency response, impulse response and maximum SPL output. Its release represented a significant advance over other acoustical prediction programs in several ways. First, it is extremely accurate because it uses high-resolution measurements. Each Meyer Sound loudspeaker model in MAPP Online is based on 1/48th octave analysis of measurements taken at rotational increments of one degree. This resolution, which is higher than any other program at the time of MAPP Online's release and still higher than most, is fine enough to properly capture the complex data, that is, phase as well as magnitude characteristics, of the loudspeaker. This accuracy was confirmed by comparing predicted responses to actual measured responses of the same system described in the prediction.

Second, MAPP Online used a patented method wherein a sound designer using an Internet-connected personal computer running Java-based client software creates a scenario for prediction, specifying a number of parameters.

Once the system parameters are defined, this information is sent over the Internet to a server at Meyer Sound headquarters in Berkeley, Calif. Running a sophisticated acoustical prediction algorithm, the server predicts the sound field that the loudspeakers will produce, as well as average and peak SPL and frequency and impulse responses at specified "virtual microphone" positions.

Within a few seconds, MAPP Online generates transmits the prediction results back to the local computer as a color graphical image.

MAPP Online was available free on request and equipped Meyer Sound users with a powerful tool that allowed them to design systems in advance with confidence that the real system would perform as the prediction indicated.

In 2006, MAPP Online Pro, the next generation of this ever-evolving software, replaced MAPP Online.
MM-4 miniature wide-range loudspeaker
Sound sculptor Bill Fontana received a commission from the city of Lyon, France, to create a work of sonic art in celebration of their new tram system, in which loudspeakers would be placed in every tram stop, reproducing sound picked up by microphones in locations around the city. The problem was that there was only four inches of space between the ceiling beams of the tram shelters, not enough room for any decent-sounding loudspeaker Fontana knew of.

Fontana brought his problem to John Meyer, who was intrigued and set to work on a solution. The result was the MM-4, an incredible loudspeaker barely four inches on each side, yet with an operating frequency range from 120 Hz to 18 kHz and a maximum peak output of more than 112 dB SPL, all at extremely low distortion levels! This performance was not easy to achieve, and the design and fabrication of the MM-4's 4-inch driver is quite tricky.

The MM-4 quickly found a niche in a variety of applications requiring extremely low profile, yet high fidelity. The MM-4 has found a great deal of use providing front fill, sometimes mounted hidden below a stage lip in a theatre or in the steps in a church. It remains one of Meyer Sound's most popular products for fixed installation.

UPM-1P receives TEC Award for Outstanding Technical Achievement, Sound Reinforcement Loudspeaker Technology
UPA-1P Arrayable Two-Way Loudspeaker System and Method
This patent describes two of the defining aspect of the UPA-1P, which are: constant directivity across frequency and the ability to be arrayed such that all speakers in the array share a common acoustic center, thus causing the array to act as a point-source in the way it radiates sound in the horizontal plane. This latter goal is achieved by creating a frequency independent focal point for the loudspeaker.

Loudspeaker systems commonly change their radiation pattern with frequency. This leads to uneven coverage and undesirable interactions between loudspeakers in arrays. The system described in the patent (which is the UPA-1P, though not specifically named as such) uses a combination of horn design, signal conditioning, and iterative prototyping to arrive at a design exhibiting frequency independence in the focal point.

The patent describes the system comprehensively, including the signal conditioning and arraying techniques.
X-10 high resolution linear control room monitor
Meyer Sound studio monitors have often grown out of new technology development efforts. The X-10 resulted from a patent filed by the University of California as a result of a collaboration with Meyer Sound. The patent incorporates cutting-edge control technology adapted from avionics, called PSAC (Pressure Sensing Active Control), which measures the acoustic output of the system and instantaneously adjusts it to match the input signal in order to achieve near-perfect linearity. In contrast to all other monitoring systems, the X-10 exhibits extended low-frequency response that does not change with variations in level, the result of which is extremely accurate and detailed reproduction.
1999
Helen Meyer awarded a Citation by the Audio Engineering Society
PSW-6 receives TEC Award for Outstanding Technical Achievement, Sound Reinforcement Loudspeaker Technology
UPM-1P ultracompact narrow coverage loudspeaker
The powered version of the popular UPM-1 loudspeaker was very well received. The UPM-1 (reportedly standing for "Ultra Perrin Meyer," in honor of John and Helen Meyer's son, now Meyer Sound's Software R&D Manager) had always been popular in theatrical applications, as well as a fill loudspeaker in installations. Self-powering made it that much more versatile.
1998
CQ-1 wide coverage and CQ-2 narrow coverage loudspeakers released
The San Francisco Opera had a conundrum. The War Memorial Opera House was undergoing a major renovation in conjunction with a seismic retrofit and wanted to put in a state-of-the-art audio system of sufficient transparency to be acceptable to purist opera fans. But the venue itself presented some severe constraints: shallow sightlines that required shallow loudspeaker cabinets, and highly reflective wall surfaces that necessitated loudspeakers with very tight pattern control.

These challenges were brought to John Meyer, who undertook a massive research effort in Meyer Sound's anechoic chamber to develop a new horn with lower distortion, excellent off-axis response, and highly controlled dispersion. Advanced modeling techniques were combined with many iterations of designs before Meyer finally came up with a design that met all of the needs.

This design was used in the creation of the CQ-1 and -2 loudspeakers, which were installed into the opera house in time for its reopening in September 1997. Although the CQ-1 and -2 were not released as products until 1998, within months of their use in the opera house, they were nominated for a TEC Award. A patent for the horn design (#5,925,856) was filed in 1997 and issued in 1999.
PSW-6 high-power cardioid subwoofer
The PSW-6 was another breakthrough technology from Meyer Sound; a product unlike any made before. In the PSW-6, a unique six-driver enclosure (four drivers in front, two in the rear) is combined with sophisticated phase manipulation circuitry to achieve a cardioid directional pattern over its entire operating range of 30 Hz to 125 Hz. Reduced low-frequency radiation to the rear results in substantially improved definition in the audience, greater control of sound on the stage and decreased low-frequency reverberation.
1997
Self-powered UPA loudspeakers receive Theater Crafts International Sound Product of the Year Award
Improved Loudspeaker Horn
Exhaustive research in Meyer Sound's anechoic chamber brought about the horn design breakthrough described by this patent. First incorporated in the CQ-1 and CQ-2, the new design achieved unprecedented uniformity within the horn's pattern, across all frequencies of operation, without the lobing typical of most other horn designs.
SB-1 Broadband Acoustical Transmitting System
This patent was for the parabolic dish technology used in the SB-1. Applied for six months before the SB-1's release, it was issued a year after the product came out.
MTS-4 Multiple Tuned High Power Bass Reflex Speaker System
With the technology described in this patent, Meyer Sound took a quantum leap forward in boosting the efficiency of a direct radiating system to provide an optimum balance of compact size and efficiency. Rather than taking the conventional approach of using one or two drivers (usually of the same size) in a single reflex enclosure, this patent describes drivers of different sizes, each in its own acoustically isolated and specifically tuned chamber. In the MTS-4A, each driver also has its own dedicated power amplifier module and control electronics.
SB-1 parabolic long-throw sound beam
The SB-1 is the first widely available, high-power sound reinforcement device based upon a parabolic reflector. By essentially "repealing" the inverse square law, the SB-1 projects frequencies from 500 Hz to 15 kHz over extremely long distances. With the SB-1, even distant corners in large stadiums can be covered using a single point-source cluster. Technology incorporated in the SB-1 received a patent the following year (Broadband Acoustical Transmitting System).
1996
MTS-4 Self-Powered Loudspeaker (patent D375,499)
This design patent covers the appearance, or "ornamental design," as the patent puts it, of the MTS-4. A separate patent, number 5,602,367, covers the MTS-4's innovative technology.
UPA-1P compact wide coverage loudspeaker
Since the release of the original UPA-1 in 1980, this loudspeaker had become one of the most recognizable products in high-quality sound reinforcement, seeing use in theatrical productions, small venues, and as a fill loudspeaker in larger touring and concert systems. Making the UPA-1 self-powered simply perpetuated its popularity. (New improvements, such as those described in patent #5,784,474, were also introduced in powered versions.) Today, the UPA-1P and -2P continue to sell steadily and thousands are in use around the world.
650-P high-power subwoofer
The 650-P was the third generation of one of the products that got Meyer Sound off the ground and onto the map. For years, the 650-P set the standard for undistorted, high-power, very low-frequency reproduction, and it remains a popular product.
1995
MTS-4 self-powered full-range loudspeaker
The self-powered MTS-4 contained, in a single compact enclosure, the ability to reproduce the entire audio spectrum for sound reinforcement, including very low frequencies, at high output with low distortion. It was a four-way system, with each driver housed in its own acoustical chamber. The MTS-4 (later upgraded to the MTS-4A, still a current product), was the subject of several U.S. and foreign patents.
“Self-Powered Series” receives Lighting Dimensions International Sound Product of the Year Award
Acoustical Ranging Transceiver
A forerunner of the SB-1 Sound Beam, ARTS was used in conjunction with the SIM system for acoustical tests involving atmospheric inversion layer analysis. This patent covers the appearance or "ornamental design" of the device.
Self-powered MSL-4 horn-loaded long-throw loudspeaker
The MSL-4 was Meyer Sound's first self-powered, high-level sound reinforcement loudspeaker. Putting the MSL-4's 1240 watts peak output in an enclosure was an entirely different challenge than making the self-powered HD-1 studio monitor, but it represented the culmination of a decades-long quest by John Meyer to make self-powered systems.

The MSL-4 worked and was well received; even today it is considered a workhorse of the industry. In fact, the success of the MSL-4 outstripped Meyer Sound's expectations, and the company soon began converting all of its products to be self-powered.

However, the challenges of making a system like the MSL-4 were considerable and, initially, some were skeptical of its practicality. Consequently, Meyer Sound stood alone in the marketplace with its self-powered systems for nearly five years before any other manufacturers took a serious stab at the technology. Even then, others have been slow to take the leap, while Meyer Sound has perfected self-powering and made converts to it around the world.

The MSL-4's cabinet design was the subject of a design patent.
Anechoic chamber built at Meyer Sound
Meyer Sound has always engaged in extensive measurement as a foundation for its R&D. For years, loudspeaker testing was done primarily in the parking lot adjoining the company's location on busy San Pablo Avenue in Berkeley. There were occasional disagreements with the neighbors on that score, and, besides, there was a limit to the precision of measurement that could be attained. (The paint marks denoting measurement angles are still visible in the parking lot.)

John Meyer decided that the needs of the research he wanted to do required that the company have its own anechoic chamber. The chamber was built in a shed that formerly housed an old gas station, a building-within-a-building. As private anechoic chambers go, Meyer Sound's is fairly large, with anechoic response allowing measurements down as low as 80 Hz.

The room is dominated by a large mechanical arm used to hold and rotate loudspeakers in fine increments for measurements such as those done to create loudspeaker models for the MAPP Online Pro acoustical prediction program. The arm was purchased from a Colorado company that makes rotation mechanisms for astronomical observatories, the only place John Meyer could find a company accustomed to making large mechanisms that could move, under program control, in small increments with high precision. Of course, the mechanism was highly customized for Meyer Sound's needs.

The first big payoff for all the investment came in the development of new horns for the CQ series of loudspeakers. The anechoic chamber is now heavily used in development, and is the location of nearly all data acquisition for the MAPP Online Pro acoustical prediction program.

HD-1 Two-Way Loudspeaker Updated : Correction Circuit & Method for Improving the Transient Behavior of a Two-Way Loudspeaker System
Method and Circuit for Improving the Polar Response of a Two-Way, Horn-Loaded Loudspeaker System
This patent concerned a system first used to establish a common, fixed acoustical center for the high- and low-frequency drivers in the UPA-1P and UPA-2P.
1992
SIM II receives R&D 100 Award from R&D Magazine.
Awarded annually by R&D Magazine since 1963, the prestigious R&D 100 recognizes the 100 most significant technological achievements of the year worldwide in a variety of disciplines. Entries are judged by the editors of R&D Magazine and a panel of experts from various universities and scientific labs including MIT, NASA Lewis Research Center, Lawrence Livermore Labs and Ames Lab. Competitors for an award usually include industrial giants like Dow Chemical and Matsushita, as well as government laboratories such as the Lawrence Berkeley Laboratory.

In 1992, on the 30th anniversary of the R&D awards, Meyer Sound Laboratories received an award for the SIM System II acoustic test and measurement system. Recognition for Meyer Sound, then still a small professional audio company, was a heady accomplishment and validation for John Meyer's vision.
1991
Correction Circuit and Method for Improving the Transient Behavior of a Two-Way Loudspeaker System
These two closely related patents describe technology that enables a two-way loudspeaker system to approach the theoretical ideal of a single point source by resolving problems the existing literature had essentially declared insoluble. The first patent deals with direct radiating systems, and covers technology incorporated in the HD-1. The second patent (applied for in 1993, two years after the first) deals with specifics related to horn-loaded systems, and defined technology soon to be incorporated into the company's self-powered series of sound reinforcement products.
SIM system II FFT analyzer
SIM System II FFT analyzer released

The introduction of the original SIM system changed the face of audio measurement by employing source independent measurement, which provided much more meaningful analysis than real-time analyzers. However, the first SIM system was built around a Bruel & Kjaer dual FFT analyzer that was not entirely optimized for the job. SIM II, built from the ground up to do source independent measurement for audio, was a huge step forward, offering three DSP engines to provide three simultaneous transfer functions, multichannel operation, constant-Q FFTs, and many other advances.

The magnitude of this breakthrough was recognized when SIM II was presented an R&D 100 Award in 1992.
1990
Improved Ohmically Isolated Input Circuit
HD-1 receives a TEC Award for Outstanding Technical Achievement, Transducer Technology
It didn't take long for the HD-1 to have an impact. The first time it was shown publicly, at the AES convention, Hundreds of orders were placed during its first public showing at 87th AES convention in New York. There was no surprise when the HD-1 was nominated for, and won, a TEC Award, which was presented during the 89th AES in Los Angeles.

This award was Meyer Sound's second TEC. In this year, the Mix Foundation, a non-profit organization, was set up and took over the TEC Awards
1989
HD-1 high definition audio monitor
The HD-1 marked a revolution in the field of studio monitoring. The first two-way device capable of an almost ideal impulse response — free from the phase distortions typical of conventional two-way systems — the HD-1 was also the company's first truly self-powered product, as the engineering team quickly realized that their ambitious design goals could be met only by creating an integrated system with all variables taken into account. With its unprecedented resolution of musical detail, the HD-1 quickly won worldwide acceptance among leading record producers, studio engineers, mastering engineers, and recording artists.

The HD-1 was never even intended to be a product; it was designed to be an in-house test source for evaluating microphones. However, in one of audio's many legendary twists of fate, Grammy-winning engineer Roger Nichols (famed for his long association with Steely Dan, among others) visited the Meyer Sound factory, happened to hear the prototype, and relentlessly implored John Meyer to make and loan him a pair to use mixing Rickie Lee Jones's Flying Cowboys album. Things took off from there. Well over 15 years later, orders continue to be filled for the HD-1.
1988
Ohmically Isolated Input Circuit
Analog audio inputs and outputs using three-pin XLR connectors have long suffered from inconsistency between manufacturers in both wiring of connectors and in input and output circuitry. As a result, miswiring has been a constant problem that creates gain problems, AC power buzzes, and even cancellations.

Originally developed to allow a SIM audio analyzer to be inserted into a sound system without deleterious effects, this patent is for an input circuit designed to avoid the injection of AC noise and provide the same gain no matter how the output feeding it is wired. The key to the circuit is that two transformers are employed in a serial, "hum-bucking" fashion such that any two of the three input pins will properly couple through one or both transformers without gain change while rejecting common-mode signals. Further, current transformers are used, rather than voltage transformers, so that the signal level passing through the transformers never reaches levels where common problems like eddy currents, ringing, phase shift, and hysteresis are encountered.

The second patent describes an improved version of this circuit that uses a single, center-tapped transformer in place of the matched pair of transformers.
Circuit and Method for Correcting Distortion in a Digital Audio System
Many early digital recording systems, notably the Sony PCM-F1, used high-order "brick wall" filters to prevent aliasing. Unfortunately, these filters introduced delay that varied with frequency, resulting in considerable phase distortion. This patent introduced a circuit to correct these phase anomalies and obtain a relatively constant group delay. The underlying technology behind the patent emerged from Meyer Sound's ongoing research into advanced phase correction circuits for what would become the HD-1 high-definition audio monitor.
1986
SIM receives MIX Magazine's TEC Award for Outstanding Technical Achievement, Acoustics Technology
The TEC Awards were created by the publishers of MIX Magazine in 1985 to recognize the contributions of audio professionals, not just for creative achievements like best engineering for an album recording, but also for product design. The award for SIM was Meyer Sound's first. Nearly every year has seen Meyer Sound nominated for a TEC Award, sometimes for more than one.
First Meyer Sound sponsorship of Montreux Jazz Festival
Claude Nobs had been a music promoter in Switzerland in the '60s. In 1966, he founded the Montreux Jazz Festival, which grew to become one of the world's largest and most prestigious music festivals. Nobs heard of the work John Meyer was doing at the Institute for Advanced Musical Studies and was bowled over by what he heard when Meyer played him a prototype loudspeaker that was in development. Nobs resolved right then that he and the Meyers would work together at some point.

By 1986, the festival was firmly established, growing steadily, and in need of better sound, so Nobs called the Meyers, who had established Meyer Sound by that time. The opportunity to help out an old friend and be the official sound sponsor for a well-respected, high-profile festival combined with the chance to try out new products in the field with a broad range of musical styles to make for an irresistible opportunity. So began the relationship between Meyer Sound and the festival, which continues to this day.
Loudspeaker Enclosure: 833 studio monitor
The 833 Studio Reference Monitor system was the next step in studio monitors after the ACD monitor Meyer Sound made in the company's earliest days. The 833 utilized dedicated control electronics and advanced horn design to achieve an extremely wide dynamic range, low distortion and controlled directivity. This patent is a design patent on the shape of the 833 cabinet.
1985
John Meyer named a Fellow of the Audio Engineering Society
The Audio Engineering Society Fellowship Award is given to a member who has rendered conspicuous service or is recognized to have made a valuable contribution to the advancement in or dissemination of knowledge of audio engineering or in the promotion of its application in practice.
1984
CP-10 complementary phase parametric equalizer released
The CP-10 was developed for use in conjunction with the first SIM analyzer. It was notable in that it can be set to mirror room resonance effects, providing correction for both magnitude and phase effects. The CP-10 created controversy when it was introduced, as a signal passed through two CP-10s, with the second set exactly the inverse of the first, resulted in a net phase shift of zero degrees. Some initially were reluctant to accept this measurable result because it seemed to contradict intuition. In any event, the CP-10 became one of the best respected parametric equalizers on the market.
First SIM analyzer: introduction of source independent measurement
Developed for live sound and test measurement applications, the first SIM system utilized a PC controlling a dual FFT analyzer to perform highly accurate measurement of loudspeaker systems in acoustic environments. It was widely hailed as a revolution in measurement systems, because, being comparative in nature, it allowed engineers to use, for the first time, program material — the music of a performance — as a test signal, instead of noise or tones. This meant that an engineer could continue performing system optimization throughout the event, accounting for changing acoustic conditions due to the effects of temperature, humidity and the presence of the audience.

Being an entirely new measurement method, Meyer Sound gave some training classes that proved to be the beginning of what became the company's ongoing worldwide seminar series today.
1983
Meyer Sound moves to current Berkeley location
Meyer Sound started life in an industrial strip mall in San Leandro, Calif., just a few miles south of Berkeley. By late 1983, the company had outgrown the small facility. In December, Meyer Sound moved to 2832 San Pablo Avenue in Berkeley. For many years, that building housed the entire company, but today it holds only the headquarters offices and the Pearson Theatre, while engineering and production have spread into six other buildings in the area.
833 studio reference monitor
Meyer Sound was formed, in part, to market the ACD studio monitor system John Meyer had developed in Switzerland. The 833 was the first studio monitor designed and manufactured at Meyer Sound. Although it came with control electronics, it was not self-powered, in fact, issues surrounding proper amplification of the 833 provided more motivation for pursuing John Meyer's vision for self-powered systems. A companion subwoofer, the 834, was also built. The 833 became a standard large-format studio monitor and many pairs remain in active use today.
1981
Trapezoidal Loudspeaker Cabinet
John Meyer had noticed during his time at McCune Sound that the sound quality of the JM3 loudspeaker system he had designed for McCune started to go down as more cabinets were added. Why? After substantial thinking and research, he determined that there were uncontrolled interactions between cabinets at work. Meyer created the trapezoidal cabinet to facilitate precise configuration of loudspeakers into horizontal arrays with an implied point source behind them. (The cabinet shape does not impact the loudspeaker's radiation pattern, but it gives more flexibility in cabinet placement and angling.) The arrayable, trapezoidal loudspeaker cabinet was a unique concept that first appeared in the Meyer Sound UPA-1 and was granted a U.S. design patent (D271,967). It soon became widely copied and is now nearly ubiquitous.
650-R2 subwoofer
The 650-R2 was the next step in the evolution of the 650 subwoofer John Meyer had built for Francis Ford Coppola's "Apocalypse Now." The 650-R2 added a second 18-inch driver and extended response down to 30 Hz. The 650-R2 had much higher output than previous subwoofers at very low distortion. Grateful Dead bassist Phil Lesh immediately seized on the 650-R2 and made it a staple of his rig for years.
MSL-3 reinforcement loudspeaker
The MSL-10 established John Meyer's ability to make large-scale loudspeaker systems capable of low distortion, flat response, and high-output. The MSL-3 grew out of the MSL-10 and represented, in essence, an MSL-10 "slice." Because it was smaller, it could be arrayed with greater versatility. The MSL-3 also held up under tough conditions and over long periods of time: the London production of Cats used the same MSL-3s for more than 20 years! The MSL-3 became a major success, for years representing the ultimate in high-level sound reinforcement loudspeakers. Hundreds of MSL-3 cabinets are still in active use to this day.
1980
UPA-1 compact wide coverage loudspeaker
The release of the UPA-1 was a milestone for sound reinforcement in general, as well as for Meyer Sound specifically. A repackaging of the technology used in the UM-1 UltraMonitor, the UPA-1 offered several advances that could fairly be termed revolutionary. For a start, it featured a high-frequency section that fully incorporated John Meyer's method of reducing distortion by balancing non-linearities of the compression driver and horn against each other, accommodating the driver's natural behavior instead of generating distortion by trying to force it into different behavior.

Second, the UPA-1 was used with a dedicated CEU. Although the UM-1 also had a CEU, the UPA-1, which was only a year behind the UM-1, created a sensation with its performance, legitimizing for many the idea of dedicated loudspeaker processing.

Finally, there was the UPA-1's trapezoidal cabinet shape. John Meyer was espousing the benefits of point-source arrays, which were not possible to achieve with rectangular boxes. The UPA-1s trapezoidal shape allowed it to be tight-packed or splayed, but to behave as if there was a sound source emanating from behind the cabinets.

With its high output, low distortion, and small footprint, the UPA-1 had exceptionally broad applications, causing it be widely embraced, but the theatre world, in particular, immediately began making the UPA-1 — which had been designed in part for the needs of Abe Jacobs, dean of Broadway sound designers — into a standard part of theatrical sound systems.
MSL-10 loudspeaker
The MSL-10 improved on the design John Meyer had employed to build the JM10 for McCune Sound. The JM10 had been the first large-scale arrayable loudspeaker and had seen use by the Grateful Dead and others. The MSL-10 actually was created for an installation at the Oakland Coliseum, where high-quality sound was desired so that the audience and players could both clearly hear the system.

The MSL-10 was a high-power, high-Q system, powered by its own MS-10 amplifiers and M-10A controller, that provided 30-degree sections that could be combined into arrays to cover areas as wide as needed. One of the design goals was to prove the validity of the architecture, then create a product that broke the MSL-10 into smaller "chunks" that could be arrayed more flexibly. That product turned out to be the MSL-3
1979
UM-1 UltraMonitor
The UltraMonitor came about when Jefferson Starship and Hot Tuna sound engineer Owsley "Bear" Stanley beseeched John Meyer for a stage monitor with the clarity of the Meyer/ACD studio monitor but more power. Meyer designed the UM-1 and the first cabinets were built by Don Pearson in the shop of his young sound company, Ultra Sound. This was the beginning of an association between Don Pearson and Meyer Sound that ended up with him joining Meyer Sound's staff as an instructor for the last year and a half of his life.

The release of the UltraMonitor marked the first time a commercially available loudspeaker was accompanied by a dedicated processor, the Control Electronics Unit, or CEU
Dedicated loudspeaker processor
A revolutionary concept when it first appeared, the Meyer Sound Control Electronics Unit (CEU) combined an active crossover circuit, frequency and phase response alignment, and protection circuits. Optimized for specific speakers, each CEU improved the overall performance and extended component life. The first CEU accompanied subwoofers designed for the 70mm release of Francis Ford Coppola's now-classic Vietnam epic, "Apocalypse Now."

The second CEU, for the UM-1 UltraMonitor, enabled the two-way stage monitor to generate extremely high output levels with low distortion, extended frequency response and unprecedented gain before feedback.
650 subwoofer created for “Apocalypse Now”
Francis Ford Coppola wanted his epic movie "Apocalypse Now" to have the most impressive, impactful sound ever heard in a movie. To that end, in its initial release, the film toured with a custom quadraphonic sound system. One of Coppola's concerns was that the napalm explosions in the "Ride of the Valkyries" helicopter attack scene be bone-rattlingly real. John Meyer's involvement began at a Berkeley demonstration of the ACD studio monitor, at which he was showing a subwoofer that had been designed to go with the ACD. Impressed by the demo,engineer Tom Scott from Coppola's Zoetrope studio approached Meyer and asked if he could create a subwoofer for Apolcaypse. Meyer created the 650 subwoofer, containing a single 18-inch driver in a sixth-order cabinet with low-distortion response down to 30 Hz, to satisfy Coppola's need.

After one tour of the 70 mm print, however, Apocalypse went to a 35 mm release, which did not seem to present as strong a demand for a subwoofer. Meyer then showed the 650 to bassist Phil Lesh of the Grateful Dead, who immediately took an interest. Eventually, a second driver was added because the single driver had a high failure rate and the 650-R2 was born. The 650-R2 lasted until self-powering was added to make the 650-P, a model still sold today. The 650 lineage is one of the most distinguished in the history of low-frequency reproduction.
Horn Speaker and Method for Producing Low Distortion Sound
The company's first patent, issued only weeks after the Meyer Sound's founding, was the result of John Meyer's pioneering research into sources of non-linearity in horn loudspeakers. Much of this work was done during the 1970s, when Meyer was director of the Acoustics Laboratory at the Institute for Advanced Musical Studies in Switzerland. The patent describes a method for reducing distortion by a factor of ten, and was first applied to horns in the UM-1 (1979) and UPA-1 (1980)
Meyer/ACD studio monitor
After returning from Switzerland to the U.S., John Meyer was contacted by Jean-Pierre Mamin, who had worked with him at the Institute for Advanced Musical Studies. Mamin (who was also key in helping Meyer Sound get started and remains a close Meyer Sound associate) was working for a company called ACD that wanted John Meyer to build a loudspeaker for use in European discos. Meyer began a search for a driver with high linearity; a difficult property to achieve. Finally, he stumbled across one from a small Swiss company and used it to design the system for ACD.

Unfortunately, the U.S. dollar fell against the Swiss franc while this was happening and the loudspeaker he'd designed suddenly became too expensive to make for use in discos, so Meyer decided to build a studio monitor with the driver instead. Thus, the Meyer/ACD studio monitor came into being.

The ACD was a proto-self-powered system, in that it included a rack with an amplifier and processing electronics. In 1979, Meyer Sound was founded to distribute the ACD, but the price, $15,000, was extremely high for 1979, and it was difficult to sell many of them.

The ACD nonetheless accomplished two important things: first, it raised the bar for distortion and flat response in studio monitors, second, it attracted attention, which led to involvement in Francis Ford Coppola's film, Apocalypse Now, and evolution of the Meyer/ACD design into both the UltraMonitor and the UPA-1.
Meyer Sound is founded
John Meyer had already started one loudspeaker company (Glyph), designed loudspeaker systems for McCune Sound Service (now McCune Audio/Video/Lighting), and founded an acoustics laboratory at Switzerland's Institute for Advanced Musical Studies. Having returned to the U.S. and spent a few years designing the JM10 for McCune and working on other projects, Meyer had designed the Meyer/ACD studio monitor for a Swiss company. Meyer Sound is formed to be the exclusive U.S. distributor for the Meyer/ACD system. Founded by John and Helen Meyer the day before Valentine's Day, the new company begins operations in a small industrial park in San Leandro, Calif., just a few miles from its current location.
1975
John Meyer creates JM10 system for McCune Sound Service
After closure of the Institute for Advanced Musical Studies in Switzerland, John and Helen Meyer returned to the U.S., where John resumed working with McCune Sound Service in San Francisco. Picking up where he had left off but using what he had learned in Switzerland, Meyer designed the JM10, a large-scale arrayable full-range loudspeaker system. McCune used the JM10 for many years, and several years later, after founding Meyer Sound, Meyer used it as the basis for the design of the MSL-10 loudspeaker.
1973
John Meyer goes to Institute for Advanced Musical Studies
John Meyer was established as a groundbreaking loudspeaker designer by 1973. In that year, he was offered the opportunity to found an acoustics laboratory at the Institute for Advanced Musical Studies in Montreux, Switzerland. The time Meyer spent there was quite fertile. He pursued a search to find a driver with high linearity, finally locating one. He also developed new ideas about reducing distortion in horns that led to Meyer Sound's first patent. These ideas and others came together in the design he created for the Meyer/ACD studio monitor. John and Helen Meyer also met Montreux Jazz Festival founder Claude Nobs at this time, a friendship that led to Meyer Sound sponsoring sound systems for the festival from 1986 to the present.

In 1974, economic conditions changed and the institute was forced to close.
1970
John Meyer becomes a loudspeaker designer at McCune Sound Service
The quadraphonic Glyph sound system built by John Meyer and installed at the San Rafael, Calif., nightclub called Pepperland was unique. Audiences took note of it, as did the bands that played there. McCune Sound Service, a local sound rental company, also took notice of it.

At that time, there were no off-the-shelf loudspeakers manufactured for professional sound reinforcement. In fact, the need for such systems had just started to manifest itself in the last five years or so with the rise of the Beatles and large rock and roll concerts. Sound companies like McCune had to design and build their own equipment.

The Glyph system created enough of an impression that McCune offered Meyer a job designing loudspeakers for them. This turned out to be a fruitful relationship that produced the JM3 and JM10 systems and served as a platform for John Meyer to explore the ideas that he later brought to maturity at Meyer Sound.
1969
Quadraphonic Glyph system installed at Pepperland
In 1969, a quadraphonic Glyph system was installed at Pepperland, a nightclub in San Rafael, Calif,, in Marin County, just over the Golden Gate Bridge from San Francisco. In its short (18 months or so) existence, Pepperland saw concerts from all of the great bands of the day, who inevitably took notice of the unusually clean and loud sound coming from the odd-looking loudspeakers.
John Meyer founds Glyph Sound Systems
After Monterey Pop, John Meyer became increasingly interested in loudspeaker design, especially in the problem that no existing loudspeakers were capable of the high-power demands bands of the late 1960s were presenting. In 1969, Meyer designed a very unusual-looking system that reproduced bass frequencies with either a 4-foot by 4-foot horn and a 14-inch diaphragm driver (the MN50 with M driver) or an 8-foot-by-8-foot fiberglass horn with a 28-inch diaphragm driver. Either could be topped by a tweeter. For all the strangeness of its appearance, the new speaker, called "the Glyph," exhibited lower distortion than other systems of the day.

Glyph Sound Systems was based on Sixth Street in Berkeley, less than a mile from Meyer Sound today. Stewart Brand featured a photo of the Glyph in The Last Whole Earth Catalog, with a caption that read, in part, "The first loud sound I've heard that didn't make me want to run. I wanted to stay and shake."
1967
John Meyer assembles system for Steve Miller at Monterey Pop Festival
In 1967, John Meyer was working at Berkeley Custom Audio, an audiophile shop in Berkeley, Calif., when a young Steve Miller came in. Miller's band was slated to play the upcoming Monterey Pop Festival and Miller, who has always been very audio-aware, wanted a better-sounding system for his bassist, Lonnie Turner. Meyer put together a horn-loaded system out of Klipsch La Scala loudspeakers, launching him on the road that would lead to Meyer Sound. Meyer and Miller remain friends to this day.

Meyer Sound Patents

From its beginning, Meyer Sound has been known as a leading innovator in performance audio products. Our list of industry firsts includes trapezoidal cabinets, dedicated loudspeaker processors, self-powered loudspeakers, source independent measurement, parabolic long-throw transducers, cardioid subwoofers, the REM manifold, Internet-enabled acoustical prediction, and more.

The technology underlying such innovations can be traced through the course of our patent history. Patents have played an important role at Meyer Sound since the company was established in 1979. Our first U.S. patent (4,152,552) was granted within weeks of the time we opened for business, and has served as a technological foundation for product development ever since.

To be valid, any claim for an intellectual (technically, “utility”) patent must mark a departure in thinking from what is generally accepted and known in the trade. But you don't have to actually make a functional device - or make anything at all, for that matter - in order to patent your idea.

At Meyer Sound, however, all our patents have been incorporated into products in some way, with tangible benefits for the professional audio community. In one sense, we use the patenting process as a framework to transform fledgling concepts into effective products. Seeking a patent disciplines our engineering team by making us more careful and thorough in our work.

Although Meyer Sound’s patent history includes several milestones in audio engineering, it doesn't tell the whole story. We haven’t sought patents on all of our new ideas. Instead we have focused our patent applications on those key concepts that define our distinctive approach to sound reproduction technology.

Milan

At Meyer Sound, we believe that advancing the industry elevates us all, so we innovate with the big picture in mind—whether we’re pioneering loudspeaker technologies, establishing new reference standards, or breaking new ground in system management tools.

The industry is at the leading edge of a new generation of networked A/V: From live concerts to Broadway theatre to houses of worship, networks let us build bigger, more complex media systems that deliver excitement on a grand scale.

With A/V increasingly residing on networks, there’s never been a greater demand for stable, reliable performance. As we look to the future, we want to align with open-source technologies that establish dependable, high-quality standards. For the first time, technology innovators across the industry are joining forces to establish a networking solution aimed at advancing the entire entertainment ecosystem: Milan.

Meet Milan

Milan is the first open solution for deterministic, reliable, and future-proof delivery of networked media. Milan is the application layer built onto the AVB network protocol that adds a framework of interoperability for professional A/V devices: While AVB addresses issues at the network infrastructure level, such as synchronization and quality of service, Milan is application focused, addressing the unique requirements of media networking including reliability, stability, scalability, and audio quality. The Milan specification and certification process guarantees these standards yet still leaves room for healthy competition and robust product development.

United For An Open Solution

AVNU Milan is developed by professional audio members of the Avnu Alliance, a consortium of leading manufacturers with a common goal of defining a new standard of interoperability in A/V networking. We understand that our products don’t exist in a vacuum: As part of an entertainment technology ecosystem, we want the ability to seamlessly communicate with other devices in that system. By working together, we’re able to create a standard quickly to address the needs of a rapidly evolving media industry. And because we’re not limiting specifications to a single manufacturer, we can guarantee that all Milan-certified devices will work together at a new level of convenience, reliability, and functionality—today and in the future.

Friendly, Foolproof, And Future-Proof

Milan builds on benefits already established in the AVB standard by further defining device requirements for compatible media streams, formats, media-clocking, redundancy, and controller software. This translates into big advantages at both the network layer and the application layer:

Reliability: Milan enables time-sensitive media files to coexist with other Ethernet traffic, without drop-outs or degradation. And because it’s a deterministic network, you can count on on-time data delivery—guaranteed.

Sustainability: As a media professional, you need an enduring standard that will scale with you and support your workflow needs today and as your systems evolve. We design products to last decades; with Milan, you’ll be confident in your investment knowing there’s a network protocol that will support your products throughout their lifetime.

It Just Works: You’re an audio professional, not an IT engineer. Milan was developed with scalability and ease of use in mind. It’s transparent, seamless, and plug-and-play simple—you can stay focused on your creativity.

Making Milan Together

At Meyer Sound, we know that when you succeed, we succeed. We’re committed to giving our customers the best tools available to support their creative vision; Milan strengthens our ability to deliver on that promise, now and in the future. We’re proud to be part of an industry movement to create solutions that benefit everyone. Because it all translates to a better entertainment experience—and that’s a goal we can all get behind.

Making Milan Together

The Self-Powered Advantage

Meyer Sound has been pioneering self-powered loudspeakers for professional installations and touring since 1995. We’ve committed to self-powered systems because we know they deliver unrivaled clarity, reliable performance, value, and ease of use.

If you’ve been thinking about investing in a self-powered system, you’ve come to the right place.

John Meyer

First, a Little History...

The story of self-powered loudspeakers is in many ways the story of Meyer Sound itself.

In the 1970s, sound reinforcement technology was inconsistent science at best, and at worst, led to show-ending failures. A young John Meyer, designing loudspeakers for San Francisco’s McCune Sound Service, wanted to bring quality and reliability to sound systems, and he knew the answer lay in self-powered loudspeakers. In 1979 Meyer founded his own speaker company; early Meyer Sound innovations include the iconic HD-1 self-powered studio monitor launched in 1989.

Today Meyer Sound offers a full range of self-powered sound reinforcement products. Meyer Sound systems can be found on tour with artists ranging from Ed Sheeran to Metallica, on Broadway and London’s West End, and in performance venues from the San Francisco Opera to the Vienna Philharmonic not to mention sports stadiums, cruise ships, and houses of worship around the world.

HD-1

Why Self-Powered?

Self-powered loudspeakers offer several advantages over their passive counterparts when it comes to fidelity, reliability, and simplicity. The great part is, you’ll start to reap the benefits of a self-powered system before you even power up.

Ease of deployment: System set-up is so much easier when you have fewer components and fewer cables to worry about being miswired. Since self-powered loudspeakers incorporate amplification, you’ll never have to deal with matching speakers to amplifiers or connecting components. You don’t have to worry about calibration of gain and crossover setting which means more time focusing on the show. Eliminating amp racks doesn’t just streamline system deployment, it streamlines your inventory whether you’re a rental house or a road warrior. And when you consider that the average amp rack weighs nearly 300 pounds and takes up four feet of truck space, the efficiencies get even clearer. Let alone when you want to fly the amplifier racks to get closer to the speakers, often requiring more rigging points and more motors.

Predictable, reliable operation: Internal amplification is closely matched to drivers. Because individual components have been optimized during manufacturing, you can expect consistent sound from show to show. Built-in, factory-optimized protection circuitry provides extra assurance without degrading signal quality. And, when you have less equipment, you have less risk of failure.

ULTRA X-40

Better frequency and phase response: Because self-powered loudspeakers incorporate sophisticated processing, they are calibrated to exhibit optimal response curves in key performance parameters. Active crossovers are more precise, sophisticated designs, and bi-amped systems are time aligned, eliminating phase issues. The result? Accurate sound throughout the speaker’s range, at any volume level.

Unparalleled clarity: In powered monitors, internal amplifiers are precision-matched to drivers, delivering optimal power at all times for cleaner sound. And because amps are built into loudspeaker cabinets, there’s no need for long lengths of connecting cable, which can become prone to distortion and signal loss.

Tighter transients: Since self-powered loudspeakers have very short internal cables, amps inside can more effectively dampen driver mechanical motion, which leads to better sonic accuracy and tighter, crisper transients. (And, there’s none of the loss in levels and signal quality inherent over long cable distances.)

Certified Safe: Nothing matters more than the safety of your staff and customers. Because self-powered loudspeakers incorporate amplification, they must undergo rigorous testing by Underwriters Laboratories and other international organizations to ensure they operate safely and guard against the risk of fire, electric shock, and inadequate structural design. Enjoy peace of mind knowing Meyer Sound powered products are certified by FCC, UL, CSA, CE, and CEE the most stringent agencies in the business.

The Problems with Passive

What about passive loudspeakers? At first glance, passive systems may seem like a bargain. But we already know that passive systems require more components and accessories than powered systems. Sonically, they exhibit potential for signal loss over distances, and it is very hard to ensure consistent, optimal sound and volume as amplifiers have many variables to consider when being matched to loudspeakers, such as cable lengths and gauge as well as the number of speakers connected to the amplifier.

Passive systems are often touted as easy to service. But because powered loudspeakers are so complex to design and build, self-powered loudspeakers usually represent the top innovations from leading manufacturers. Better quality translates to better reliability, which means fewer maintenance issues in the long run.

At face value, passive systems might seem less expensive and easier to maintain. But once you start adding in amps, cables, and other components not to mention increased transport and labor costs you’ll find that those savings just don’t add up to a better value.

Step Up to a Self-Powered System

Once you recognize all of the advantages inherent in self-powered loudspeaker systems, it’s easy to understand why the world’s top venues and productions rely on them to deliver consistently stunning sound.
