Ground polarity switch, Reset/circuit breaker switch

Rear Panel

27 ground polarity switch

The ground switch is a 3-position‚ rocker-type switch. Under normal operation it should be in the center (zero) position. If hum or noise is present with the ground switch in the center position‚ place the ground polarity switch to positive or negative (+ or -) to minimize hum. Should a problem continue‚ consult your authorized Peavey dealer‚ the Peavey factory or a qualified service technician. Note: The ground switch is not functional on 220/240 Volt models.

28 reset/circuit breaker switch

Use this switch to restore power to the unit when the internal breaker is tripped. Turn the power switch to the off position before resetting the breaker. To reset‚ push the reset button in and release it. Turn the unit back on and confirm that the power LED is on. If the breaker is tripped again upon power-up‚ consult your authorized Peavey dealer‚ the Peavey factory or a qualified service technician.

29 IEC connector/detachable line cord

For your safety‚ we have incorporated a detachable‚ 3-wire line (mains) cord with proper grounding facilities. It is not advisable to remove the ground pin under any circumstances. If it is necessary to use the amp without proper grounding facilities‚ a suitable grounding adapter should be used. Refer to the back of your amp for the proper voltage requirements before connecting to a power receptacle.

30 speaker output jacks

There are two 1/4" jacks and one Neutrik type jack that provide the powered signal from the amplifier. Each connector is electrically the same (parallel). Use one of the jacks to connect your speaker cabinet and the other to add a second speaker cabinet in parallel. The minimum speaker load impedance is 2 Ohms or two 4 Ohm speakers in parallel.

Warning: To prevent the amplifier from overheating‚ the front and rear fan vents should remain clear of obstructions.

31 power amp input

Used to connect a line level signal to the power amplifier (i.e. external preamp). This jack‚ when used‚ disconnects the internal preamp.

32 preamp out

The preamp output can be used to route the amplified signal to a mixing console‚ tape recorder or other device. Connect the preamp output using a shielded cable to an input of one of these devices. This does not affect the operation of the amplifier. The preamp out and power amp in jacks can also be used as a line level effects patch point.

33 remote jack switch

Provided for an optional footswitch. Allows remote selection of the input mute and the effects loop. Mute switch on front panel must be depressed to the IN position for the footswitch to function properly.

34 effects return

Input for returning signals from an external low-level effects device or signal processing unit.
