Troubleshooting
Situation Indication Action
Signal LED not lit
Clip LEDs not lit
Check AC plug. Confirm that AC outlet works
by plugging in another device.
Signal LED not lit Make sure the signal source is operating and
try another cable. Check position of Volume
Pots.
Signal LEDs responding to signal level Check the speaker wiring for breaks.
Try another speaker and cable.
No Sound
Protect LED is lit Overheating will cause protective muting.
Check for proper ventilation.
No Channel
Separation
No Channel Separation 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
Power LED is lit A faulty speaker or a loose connection could
cause this. Check the wiring and try another
speaker.
Signal LEDs responding to signal level
The signal source might be clipping. Keep the
volume pots at least halfway up so that the
source does not have to be overdriven.
Distorted Sound
Clip LEDs not lit Keep the volume pots at least halfway up and
try changing input sensitivity with the gain
selector on the rear.
Hiss Hiss 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.
Squeals and
Feedback
Squeals and Feedback 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.
