Action
Check AC plug. Confirm that AC outlet works by plugging in
another device.
Check for a shorted speaker cable or speaker/driver.
Check the speaker wiring for breaks.
Try another speaker and cable.
Overheating will cause protective muting. Check for proper
ventilation. If the fan isn't running the amplifier requires
servicing.
Check the mode indicators on the front 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 from 1,4 V to 32 dB or 26 dB 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.
Check connection between computer and any routers or
switched in the network. Reboot computer. If issue is not
resolved, consider replacing CAT-5 Cables
