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.
Output Current LEDs are lit
Signal LED not lit (or low)
Check for a shorted speaker cable or speaker/driver.
Output Current LEDs not lit
Signal LEDs responding to signal level
Check the speaker wiring for breaks.
Try another speaker and cable.
No Sound
Clip/Mute LEDs show red, and Protect
status indicator is illuminated (Protect
Mode)
Overheating will cause protective muting. Check for proper
ventilation. If the fan isn’t running the amplifier requires
servicing.
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 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 from 1,4 V to 32 dB or 26 dB 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.
Comm LED lit Check connection between computer and any routers or
switched in the network. Reboot computer. If issue is not
resolved, consider replacing CAT-5 Cables
Protea
Communications
Failure
Comm LED not lit Check connection between amplifier and network. Reboot
computer. If issue is not resolved, consider replacing CAT-5
