Troubleshooting
No power light on front panel switch
Ensure IEC inlet is connected to mains and lead is in good condition
Ensure mains outlet is switched on
Power light is on but no other LEDs and no
output Check input signal and connection leads
Ensure channel gain controls are not turned fully down
Power light and Signal LEDs are lit but no
output
Check speaker cabinets are in good working order
Check speaker leads are in good condition and connected properly
PROTECT LED is lit and there is no output
Switch off and disconnect from mains
Check speakers are in good working order and not shorted out (using a multi-tester)
After checking all connected items, power up again
If still in Protect Mode, switch off again and refer to qualified service personnel
Ensure cooling vents are clear and amplifier is not overheated
Output is very distorted and “CLIP” LEDs
are lighting
Check the speaker impedance is not below 4 Ohms per channel (8 Ohms if bridged)
Turn down the input level from audio source
Turn down channel gain controls
Output is working but at very low level
Ensure input source is at line level
Increase input level from audio source
Turn up channel gain controls
Errors and omissions excepted.
