Category Description
ALL
OVER SPKR CNT
Over Speaker Count
Warning
A lower load impedance has been
measured than was predicted by the
Load Library for the assigned speaker
type.
10000Q
14000
PAL ACTIVE
n/a
Fault
Total amplifier power being delivered has
exceeded the safe maximum value and
the PAL has become active.
20000Q PAL ACTIVE
n/a
Warning
Output power is limited due to the PSU
maximum current or power level has
been reached and PAL has become
active.
ALL
PSU FAULT
Frame Fault: PSU Undervoltage Fault
The Power supply did not start up
properly. It could be due to undervoltage
on the mains or due to an internal non
user-serviceable fault. If the mains are
checked to be OK and the fault persists
the unit should be returned to your
dealer.
20000Q PSU POWER
PROT
Frame Fault: PSU Power
Protect
Fault
Low input voltage, high power demand.
20000Q PTL ACTIVE
N/A
Warning
The output power is limited due high
temperature in the Power supply and the
PSU Temperature Limiter is active
ALL
SENSE FAULT
Frame warning: Sense Fault
Warning
The output Voltage and Current sensors
are lost. The PLM is OK for continued
operation but is at risk of entering
protective mutes states. Return device
to dealer.
ALL
SERVICE CH.
Channel Fault: Unit Needs
Service
Fault
One or more breakers in the power stage
have blown. This is not a user-servicable
fault; return device to dealer.
ALL
SHORT CIRCUIT
Channel Fault: Short Circuit
Protection
Fault
The PLM is measuring both very high
load current and very low output voltage.
Short circuit protection is active.
ALL
SPKSAFE INACT
SpeakerSafe Not Started
Warning
Warns that after LoadSmart verification,
SpeakerSafe monitoring was not started.
ALL
TEMP FLT:CH
Temp Fault: Amp Channel
Fault
Temperature in the power output stage
exceeds safety limit.
ALL
TEMP FLT:DSP
Temp Fault: DSP Area
Fault
The temperature of the PLM’s process-
ing circuitry has exceeded its safety
limit. Audio is not muted, but continued
operation at this temperature is not
recommended.
ALL
TEMP FLT:MAG
Temp Fault: Speaker Magnet
Fault
The temperature of the speaker magnet
estimated by SpeakerSafe, has exceeded
the manufacturers’ recommended
maximum.
