The MM-4XP miniature loudspeaker is a self-powered loudspeaker 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 a house
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 solutions.
The MM-4XP meets the same exceptional performance standards established by its predeces-
sor, 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 factory, delivers an impressive
maximum peak SPL of 113 dB, and has 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 that the MM-4XP performs exceedingly
well even when driven into overload.
The MM-4XP's amplifier and signal-processing
circuits are designed to store DC power and
tolerate voltage drops, thereby accommodating light-gauge cables and long cable runs. The
MM-4XP receives balanced audio and DC power
from a SwitchCraft EN3 connector on its rear
panel. The sealed, 5-pin EN3 connector provides
protection against harsh environmental conditions
when the MM-4XP is installed outdoors.
MM-4XP loudspeaker systems require an external MPS Power Supply. The MPS-488 rackmount 8-channel power supply is ideal for larger installations with multiple loudspeakers and distributes power and audio signal, while the compact MPS-481 is designed for powering single loudspeakers individually.
Powering the MM-4XP from a unipolar external power source reduces induced noise significantly and eliminates the need for wiring conduits.
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 standard
white or black anodized finishes with a perforated
steel grille. It can also be custom painted to match
specific color schemes. The MUB-MM4XP U-bracket
is available for mounting the loudspeaker on walls
and ceilings at adjustable angles.
