Type Description
Power supply The temperature of the PLM's PSU
temperature has exceeded its safety limit.
Speaker Voice Coil The temperature of the speaker
temperature fault voice coil (estimated by Speaker-
Safe) has exceeded the manufac-
turers' recommended maximum.
Power output High temperature in the power
temperature warning output stage.
Speaker magnet The temperature of the speaker
temperature magnet is high (estimated by
SpeakerSafe).
Speaker voice coil The temperature of the speaker
temperature voice coil is high (estimated by
SpeakerSafe).
Load uncertainty When speaker Fingerprints are
taken a tolerance band is also
defined to take into account
production variations. If LoadSmart
results lie in this band a Load
uncertainty warning results. The
user should re-check the load and
if all appears to be correct it is likely
that normal operation will result.
Fewer Speakers A higher load impedance has been
measured than was predicted by
the Load Library for the assigned
speaker type.
VHF at output An exceptionally high level of
continuous HF has been detected
at the PLM's power output stage.
Voltage limiter active The peak voltage at the output
terminals has exceeded the
user-defined safe maximum.
Load type mismatch LoadSmart is measuring load
characteristics which differ from
those of the assigned speaker type.
