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.

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.
