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 channel attenuators.
Signal LEDs responding to signal level Check the speaker wiring for breaks.
Try another speaker and cable.
No Sound
Signal LEDs show red (Protect Mode) Overheating will cause protective muting. Check for
proper ventilation.
No Channel
Separation
No Channel Separation Check the mode indicators on the front panel and make
sure the mode selector on the rear panel is in the two
channel (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.
