MAINS > 270 V
Power supply detects mains voltage
above operation voltage. Protective shut
down, auto restart attempt
Check mains distribution/
connection
Fault
Mains voltage below
65 V
MAINS < 65 V
Power supply detects mains voltage
below operation voltage. Protective shut
down, auto restart attempt
Check mains distribution/
connection
Fault
Power supply fault PSU FAULT Internal power supply fault
Check mains distribution/
connection.Restart device;
if not cleared it needs
servicing
Fault
Check mains CHECK MAINS
Power supply detects unstable mains
supply. Protective shut down,
auto restart attempt
Check mains distribution/
connection
Fault

Warning
Under speaker count UNDER SPKR CNT Both LoadPilot tones above thresholds Check load or calibration
Warning
Speaker short SPKR SHORT Both LoadPilot tones below thresholds Check load or calibration
Warning
Speaker damaged SPKR DAMAGED
One LoadPilot tone is above or
below threshold
Check load or calibration
Fault
No load NO LOAD
At least one LoadPilot tone above
measurable area of signicantly
above thresholds
Check load or calibration
Fault

Warning
Temp warning amplier channel TEMP WARN
Amplier channel is
approaching critical
Improve cooling or reduce
output power to avoid
temperature becoming
critical
Fault
Temp Fault amplier channel TEMP FAULT
