REAR PANEL

(11) POWER SWITCH

Turns the unit ON or OFF. Always turn level controls down before turning on the unit.

(12) VOLTAGE SELECTOR SWITCH

For selecting the proper voltage (115/230VAC) to match the power supply in your area.

Note: To avoid damage to your unit, always make sure this switch is set to the correct supply voltage. Damage caused by improper use is not covered by the warranty.

(13) POWER CONNECTOR WITH FUSE HOLDER

This standard IEC power cord receptacle is used to connect the AC power to your unit. It features a built-in fuse holder for a 5X20mm, (4A/250V for 115VAC, and 2A/250V for 230VAC operation) fast-blow fuse. If the fuse continuously blows, shut off the unit and have it serviced by qualified service personnel.

(14) MONO SPEAKER OUTPUTS

Two 1/4” (6.3mm) jacks, each powered by its own separate amplifier output stage, for connecting one or two 8 ohms speaker cabinets.

CAUTION: Do not overload the MPM 4130 with speaker loads less than 4 ohms as this will degrade performance and may harm the unit.

(15) MAIN OUT/AMP IN

This unbalanced insert point is a break between the main out and the mixer main signal and the main amplifier. This insert is a 1/4” TRS phone jack which is normally bypassed. When a 1/4” TRS phone plug is inserted, the signal path is broken. Depending on the wiring of the plug inserted into this jack, the MPM 4130 can be used as either a mixer for a power amplifier or as a power amplifier for an external input line level signal from a preamp or mixer. Alternatively the jack can be used as an insert point for an external effects device to process the output signal from the mixer section of the MPM 4130 and return it pre the power amplifier output.
