XLR/
RCA
Source Inputs
The Source Inputs 1,2,3 and 4 are stereo RCA unbalanced
jacks, which feed signal to the front panel routing switches.
Maximum signal level is +24dB. The Left and Right signals
are summed together and the mono signal is distributed to
the Zone Outputs.
Unbalanced Outputs
The Unbalanced Outputs are mono RCA jacks that always
provide an unbalanced version of the output signal at the
balanced XLR jacks. Maximum output level is +16dB.
Balanced Outputs
The Balanced Output jacks are male XLR, pin 2 positive,
that deliver the master output signal to the sound system
amplifiers. Signal is line level and mono. Maximum output
level is +22dB.
Cooling Fan
The Fan is installed to pull clean air into the chassis
through the attached filter and exhaust through
perforations in the sides of the unit. The filter helps keep
the inside of the MPM4 clean and should be removed and
washed periodically to maintain optimum performance.
Ensure that airflow to the fan and side vents is not
restricted.
AC Inlet
The universal IEC inlet connects to the incoming AC line to
the Power Supply. The MPM4 operates with 100-250VAC
and is rated at 25 Watts. All settings of the MPM4 are
saved in non-volatile memory through power cycling. The
MPM4 powers up with the same settings that it had when
power was removed. All settings are recorded ten
seconds after any control change is made.
Remote Controls
The Remote Control Connections allow optional MPM4R
remote control accessory plates to be used for source
selection and volume control. One MPM4R can be placed
in each zone using CAT5 cable up to 1500' from the MPM4
master unit. Connectors are 8 pin RJ45 plugs on both
ends wired straight through. The MPM4R uses all eight
wires in the cable.

REAR PANEL CONNECTIONS AND
SWITCHES
MPM4R remote control units
allow the user to select any
of the four Source Inputs and
control the audio volume in
each Zone without having to
access the main MPM4 unit.
One MPM4R can be used in
each of the four Zones.
Connections between the
MPM4R and the main unit
are made through RJ-45
jacks using CAT 5 wire.
Cable length can be as long
as 1500 feet. MPM4R
remote controls use a
Decora style insert plate for
easy installation in standard
electrical boxes.
