Description
The temperature of the PLM's PSU has exceeded
its safety limit
The temperature of the speaker voice coil
(estimated by SpeakerSafe) has exceeded the
manufacturers' recommended maximum
High temperature in the power output stage
The temperature of the speaker magnet is high
(estimated by SpeakerSafe)
The temperature of the speaker voice coil is high
(estimated by SpeakerSafe)
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.
A higher load impedance has been measured than
was predicted by the Load Library for the assigned
speaker type
An exceptionally high level of continuous HF has
been detected at the PLM's power output stage
The peak voltage at the output terminals has
exceeded the user-defined safe maximum.
LoadSmart is measuring load characteristics which
differ from those of the assigned speaker type
