Action

Check AC plug. Confirm that AC outlet works

by plugging in another device.

Make sure the signal source is operating and

try another cable. Check position of Volume

Pots.

Check the speaker wiring for breaks.

Try another speaker and cable.

Overheating will cause protective muting.

Check for proper ventilation.

Check the mode indicators on the back panel

and make sure the mode selector on the rear

panel is in the stereo position. Make sure

other equipment in the signal path such as

mixers and preamps are set for stereo, not

mono

A faulty speaker or a loose connection could

cause this. Check the wiring and try another

speaker.

The signal source might be clipping. Keep the

volume pots at least halfway up so that the

source does not have to be overdriven.

Keep the volume pots at least halfway up and

try changing input sensitivity with the gain

selector on the rear.

Unplug the amplifier input to confirm that the

hiss is coming from the source or from a device

upstream. Erratic or popping noises indicate an

electronic fault in the offending unit. To keep

the noise floor low, operate the primary signal

source at full level, without clipping. Avoid

boosting the signal further between the source

and the amplifier.

Microphone feedback should be eliminated

with mixer controls. If noise continues to build

up with no microphone gain, there is a serious

fault in the signal processors or cables.

Working in succession from the signal source

towards the amplifier and check each device in

the signal path by reducing its gain or by

unplugging it.
