Description
The audio signal has been muted in the power
output stage
An internal audio fault has arisen and the unit needs
servicing.
Ensures that the PLM's power output stages are not
overloaded. This should never happen during normal
program material.
The PLM is no longer able to communicate with the
Dolby Lake Controller.
PLM's power output stage current has exceeded
the fixed safe maximum and the Current Peak
Limiter has become active to limit it.
The input signal level is too high and is causing
clipping at the input stage
A SpeakerSafe warning indicating insufficient data
to produce reliable results. This may occur, for
example, if a channel is being driven at a very low
level.
A Module containing a fingerprint has been loaded,
but the load is yet to be verified with LoadSmart.
The audio signal has been muted at the Module
input of the Dolby Lake processor
The audio signal has been muted in the output stage
of the Dolby Lake processor
The signal level on the outputs of the Dolby Lake
processing module is too high and is clipping.
The chosen input type has been deselected or lost
and the input type selector has no alternative input
sources in the priority list.
LoadSmart load verification is in progress
No load detected at the power output channel.
A lower load impedance has been measured than
was predicted by the Load Library for the assigned
speaker type
Total amplifier power being delivered has exceeded
the safe maximum value and the PAL has become
active.
One or more fuses in the power stage have blown.
This is not a user-servicable fault and the unit should
be returned to your dealer.
The Power supply did not start up properly. It could
be due to undervoltage on the mains or due to an
internal non user serviceably fault. If the mains are
checked to be OK and the fault persists the unit
should be returned to your dealer.
The PLM is measuring both very high load current
and very low output voltage. Short circuit protection
is active.
Warns that after LoadSmart verification,
SpeakerSafe monitoring was not started
Temperature in the power output stage exceeds
safety limit
The temperature of the PLM's processing circuitry
has exceeded its safety limit
The temperature of the speaker magnet estimated
by SpeakerSafe, has exceeded the manufacturers'
recommended maximum
