CAL

Take Directing Sound to a New Level

Beam Steering so Precise, It's Unprecedented

Designed primarily for vocal reproduction in fixed installations, CAL loudspeakers produce a vertical beam of programmable width and then digitally steer the beam’s pattern up to 30 degrees up or down for best intelligibility.

Three Models to Choose From

CAL comes in three models – 32, 64, 96 – each providing a different maximum output level over an operating frequency range of 100 Hz to 16 kHz.

One Speaker. Powerful Range

A single, unobtrusive CAL loudspeaker can provide clear vocal reproduction over a large area while minimizing undesirable reflections.

Large-scale

CAL is a great choice for airports, convention centers, places of worship, stadiums, shopping malls, retails spaces, and reverberant spaces requiring low-profile sound reinforcement for voice reproduction.

Seamless Interoperability with AVB

As the first loudspeaker to claim AVnu certification, CAL will have seamless interoperability with certified AVB devices from other vendors, and offer numerous advantages of the open IEEE AVB standards.


Quantum Advancement in Coverage Control

Custom Drivers and Tweeters

Designed and optimized for beam steering, the CAL self-powered steerable column array loudspeakers provide an unprecedented level of accuracy both in its sonic quality and its directionality.

Flexible and Customizable

Flexible mounting options allow users to mount CAL loudspeakers against walls or columns, and custom colors ensure they will blend into any background. Weather protection is standard and permits outdoor installations, making it easy to integrate CAL into any environment.

Sophisticated Digital Control

Greater precision requires greater processing power and lower-level control. This is why CAL powers and controls every driver individually, and each CAL loudspeaker houses advanced processors that use the best algorithms to run intensive mathematical models in real time.

Solutions for Accuracy

CAL's steering enables system designers to provide directed coverage even when mounting options in a venue do not allow physically aiming the loudspeaker to the desired coverage area. Multiple or split beams can be used as needed – for example, a split beam can be used to avoid sound hitting a reflective balcony surface.

Steering the Sound

Thanks to the vertical steering capability of CAL, we were able to precisely direct the beam angles to the seating areas in each room... CAL gave us astounding results.

CAL Clarifies Communication

[With CAL,] no matter where you are sitting in the audience, the sound is always present, at just the right level. It goes beyond just excellent intelligibility—you get the feeling the person is right there in front of you, even when speaking from across the room

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.

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.

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, self-powered floor 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.
