The MM-4XP self-powered miniature loudspeaker, with IntelligentDC technology, was designed for high-quality distributed systems. Housed in a compact aluminum enclosure, the MM-4XP is especially suitable for installations involving space limitations and visibility concerns, such as fill and spot coverage, and hidden locations like chancel steps in houses of worship. Its flexible and easy-to-configure mounting options, as well as its ability to effortlessly reproduce both speech and music, make it an excellent choice for fixed applications, theatrical presentations (stage lip frontfill), and small portable systems for corporate AV.

The MM-4XP meets the same exceptional performance standards established by its predecessor, the MM-4, and adds the advantages of self-powered systems with onboard amplification and signal processing.

The MM-4XP's proprietary 4-inch cone transducer, manufactured at Meyer Sound's Berkeley, California factory, delivers an impressive maximum peak SPL of 113 dB and a wide operating frequency range of 120 Hz to 18 kHz with very low distortion. The MM-4XP exhibits the same high intelligibility and flat frequency and phase responses for which Meyer Sound loudspeakers are known. Peak and rms limiters regulate loudspeaker temperatures and excursion, ensuring the MM-4XP performs exceedingly well even when driven into overload.

With IntelligentDC technology, the MM-4XP receives power and balanced audio from a SwitchCraft® EN3TM 5-pin male input connector on its rear panel. The sealed EN3 connector provides protection against harsh environmental conditions when the MM-4XP is installed outdoors. The MM-4XP's amplifier and signal-processing circuits were designed to store DC power and tolerate voltage drops, thereby accommodating light-gauge cables and long cable runs. MM-4XP loudspeakers require a Meyer Sound external power supply. The compact MPS-481 powers a single loudspeaker and includes a 10-foot composite cable that routes both DC power and balanced audio, received from its XLR input connector, to the MM-4XP. The MPS-488HP IntelligentDC power supply is ideal for larger installations with multiple loudspeakers; the single-space 19-inch rack unit distributes DC power and balanced audio to up to eight MM-4XP loudspeakers or other Meyer Sound low-voltage loudspeakers. Meyer Sound's RMS remote monitoring system is available as an option for the MPS-488HP.

The Meyer Sound power supplies can deliver DC power to MM-4XP loudspeakers at cable lengths up to 300 feet with just 1 dB of loss in peak SPL using 18 AWG wire. The use of composite multiconductor cables (such as Belden® 1502 or equivalent) allows a single cable to carry both DC power and balanced audio to the MM-4XP. Longer cable lengths are possible for moderate applications that don't drive the loudspeakers to maximum output, or for installations with heavier wire gauges. Powering the MM-4XP from a unipolar external power source reduces induced noise significantly and eliminates the need for wiring conduits. For information and specifications for the Meyer Sound power supplies, refer to their respective datasheets.

The MM-4XP's extruded aluminum enclosure acts as a heat sink to dissipate heat from the driver's voice coil. The enclosure is available in a black anodized or standard white painted finish and includes a perforated steel grille frame. The enclosure can also be custom painted to match specific color schemes. The optional MUB-MM4XP U-bracket mounts the loudspeaker on walls and ceilings at adjustable angles.
