CHAPTER 1: INTRODUCTION

MM-10XP Subwoofer
The MM-10XP is powered by an external 48 V DC power
supply, eliminating the need for wiring conduits while still
preserving the advantages of self-powered loudspeaker
systems. The unit's onboard amplifier and signal-processing
circuits were designed to store DC power and tolerate volt-
age drops, thereby accommodating light-gauge cables and
lengthy cable runs. The MM-10XP is available with either a
Phoenix™ 5-pin male or sealed SwitchCraft
®
EN3™ male
connector for receiving balanced audio and DC power. The
EN3 connector is ideal for outdoor, all-weather use.
MPS-488HP External Power Supply
MM-10XPs require an MPS-488HP external power supply.
The single-space 19-inch rack unit receives balanced audio
from its XLR female inputs and routes the audio, along with
48 V of DC power, to its channel outputs. The channel out-
puts — equipped with either Phoenix 5-pin male connectors
or EN3 5-pin female connectors — can deliver DC power to
up to eight MM-10XP subwoofers.
Cable lengths up to 150 feet for DC power are possible
when using 18-AWG wire, with just 1 dB of loss in peak SPL.
Longer cable runs are possible for moderate applications
that don't drive the subwoofers to maximum output, or for
installations with heavier wire gauges.
The use of composite multiconductor cables (such as
Belden
®
1502) allows a single cable to carry both DC power
and balanced audio to the MM-10XPs.
MM-10AC Subwoofer
The MM-10AC is ideal for fixed installations and portable
applications where AC power is readily available to power
the unit. The MM-10AC includes an internal power supply
and locking PowerCon connectors for AC input and AC loop
output (for powering additional MM-10AC subwoofers). The
MM-10AC receives audio from an XLR female input, and
also includes an XLR male loop output for daisy-chaining
audio signals.
MM-10ACX Subwoofer
The MM-10ACX model includes onboard DC power and
audio routing for driving a pair of MM-4XP miniature loud-
speakers, or a single UP-4XP ultracompact loudspeaker,
effectively placing the MM-10ACX at the heart of an
extremely capable compact, full-range loudspeaker system.
Three XLR female inputs are included for receiving audio for
the subwoofer and two satellite loudspeakers. The
MM-10ACX is available with either Phoenix 5-Pin male or EN3
5-pin female satellite outputs. A two-channel stereo signal
can be patched to the satellite inputs and summed and routed
to the subwoofer if necessary.
MM-10 OPTIONS
Additional options for the MM-10 include the MUB-MM10
U-bracket for mounting the subwoofer on ceilings and walls;
weather protection, complete with a rain hood, for outdoor
all-weather use; and custom color finishes for installations
and applications with specific cosmetic requirements.
