Category/Type Name On screen text Description Action
Fault
Temperature fault
power supply
TEMP FLT:PSU
Power supply temperature reached
internal protection limit
Automatically restarts
when cooled down
Fault
Temperature fault
DSP area
TEMP FLT:DSP
DSP area reached
critical temperature
Improve cooling or
reduce power
PSU
Warning
Under Voltage Limit UVL ACTIVE
The Under Voltage limiter is active a
the mains supply is approaching
the lower end of the device’s
operational voltage. Output power
is decreased to ensure mains
distribution does not collapse
Increase mains distribution
stiffness or reduce output
power to avoid limiting
Warning
Power Average Limit PAL ACTIVE
Amplifi er is reducing output power due
to average power or mains current
draw is above safe operating levels
Reduce output power
to avoid limiting
Warning
Breaker Emulation Limit BEL ACTIVE
Power supply is reducing mains current
draw to stay within BEL confi gured
nominal current and profi le
Improve mains distribution
and update BEL
confi guration or reduce
output power to avoid
limiting
Warning
Mains supply glitch MAINS GLITCH
Mains glitch (missing cycles) was
detected on the mains inlet
Check mains distribution/
connection
Fault
Need service NEED SERVICE:1–8 Power supply internal error
Restart device; if not
cleared it needs service
Fault
Mains voltage above
400 volt peak
MAINS>400 VPK
Power supply detects mains voltage
above 400 volt peak. Protective shut
down, auto restart attempt
Check mains distribution/
connection
Fault
Mains voltage above
270 V
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 service
Fault
Check mains CHECK MAINS
Power supply detects unstable
mains supply. Protective shut down,
auto restart attempt
Check mains distribution/
connection
Fault
Power supply power protect PSU POWER PROT
Too high output power for too low
mains supply voltage. Protective
shut down, auto restart attempt
Improve mains supply
voltage or reduce
output power
LOAD
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
Category/Type Name On screen text Description Action
Warning
Under speaker count UNDER SPKR CNT
Both LoadPilot tones above
thresholds or LoadSmart detected
fewer speakers than expected
Check load, cabling and
calibration
Warning
More speakers OVR SPKR COUNT
LoadSmart detected more speakers
than expected
Check load and
cabling or fi ngerprint
Warning
Uncertain about load UNCERTAIN LOAD LoadSmart uncertain about load
Check load and
cabling or fi ngerprint
Fault
No load NO LOAD
At least one LoadPilot tone above
measurable area or signifi cantly
above thresholds
Check load or calibration
Fault
Wrong load WRONG LOAD
LoadSmart detected impedance
response output model
Check load and
cabling or fi ngerprint
Fault
Short circuit SHORT CIRCUIT
LoadPilot or full frequency analysis
below short threshold or hardware
short protection
Check load and cabling

Warning
Temp warning amplifi er
channel
TEMP WARN
Amplifi er channel is approaching
critical temperature
Improve cooling or reduce
output power to avoid
temperature becoming
critical
Warning
(D200, D120,
D80 only)
Very high frequency warning VHF WARNING
Amplifi er channel gain
reduction due to VHF content
Check input signal
Fault
Temp Fault amplifi er channel TEMP FAULT
Amplifi er channel has reached
internal protection limit
Automatically unmutes
