The 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.
The 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 applica-
tions 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.
The 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.
The 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.
