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.
