REAR PANEL
14. SEND JACK
1/4"/6.3mm TS phone jack. Connects the MPM 480 to the input of the external effects unit. The Send/Return
effects loop utilizes the signal from the master mixer and is before the amplifier. Normally, with no plug in the
Send jack, this master signal is routed straight through to the amplifier. If a plug is connected to the Send
jack, it will interrupt the master signal, and the signal must be routed back through the Return jack (after pro-
cessing by the external effects device) or there will be no signal to the amplifier. When using the Send/Re-
turn effects loop, set the final volume of the MPM 480 with the output level control of the effects device
being used.
15. RETURN JACK
1/4"/6.3mm TS phone jack. Connects the MPM 480 to the output of the external effects unit. The volume of
the MPM 480 is controlled by the level input to the return jack, which is just before the amplifier, and so is
adjusted by the volume control of the effects device being used in the Send/Return effects loop.
16. MONO SPEAKERS OUTPUTS
Two 1/4" (6.3mm) jacks, each powered by its own separate amplifier output stage, for connecting one or two
8
Ω
speaker cabinets.
CAUTION: Do not overload the MPM 480 with speaker loads less than 4
Ω
as this will degrade
performance and may harm the unit.
17. CD/TAPE JACKS
Two RCA jacks for inputting a stereo signal from a tape or CD source. This signal is mixed into the master
signal with the CD/Tape volume control (10). Although the input signal may be stereo, it will be
automatically mixed into a mono signal for amplification by the MPM 480, so relative balancing of left and
right signals must be done by the stereo level controls of the source output. This CD/Tape input is, in effect, a
5th input to the MPM 480 and allows added flexibility in mixing in external music sources.
18. POWER CORD CONNECTOR
This standard IEC receptacle is used to connect the AC power source to your powered mixer. Power
requirements: 115VAC or 230VAC (see 20 below)
19. FUSE HOLDER
When the fuse blows, replace it with the same type fuse, size and power rating (see SPECIFICATIONS).
If it continuously blows, stop using the unit and have it serviced by qualified personnel.
20. VOLTAGE SELECTOR SWITCH
For selecting the proper voltage (115/230VAC) to match the power supply in your area.
