Peavey IRM 8150 manual Power Switch, LINE CORD 120 V PRODUCTS ONLY, Output Barrier Strip

VENT VOIDING THE WARRANTY. If the amp repeatedly blows fuses, it should be taken to a qualified service center for repair.

WARNING: THE FUSE SHOULD ONLY BE REPLACED WHEN THE POWER CORD HAS BEEN DISCONNECTED FROM ITS POWER SOURCE.

POWER SWITCH (28)

Center position is OFF. Two ON positions are provided, one of which will properly ground the amplifier. Switch to the ON side that yields the lowest amount of residual hum or popping noise when the instrument is touched. 220 and 240 volt models have a two-way on/off switch only.

LINE CORD (120 V PRODUCTS ONLY) (29)

For your safety, we have incorporated a three-wire line (mains) cable with proper grounding facilities. It is not advisable to remove the ground pin under any circumstances. If it is necessary to use the equipment without proper grounding facilities, suitable grounding adaptors should be used. Less noise and greatly reduced shock hazard exist when the unit is operated with the proper grounded receptacles.

OUTPUT BARRIER STRIP (30)

Provided for connection of external speakers. Power output is 150 watts RMS. This is available as a direct output from the power amplifier or as transformer isolated outputs. Transformer outputs can be used for an 8 ohm

(35 V) loudspeaker or used to drive 25 V or 70 V speaker systems. Only one output should be used at a time. The balanced transformer isolated line level output is provided for connection to booster power amplifiers, additional sound systems, etc. This output is designed to deliver 1 V RMS into a 600 ohm load.
