AMPLIFIER
THERMAL WARNING This indicator lights red when the power amp's temperature exceeds the pre-set threshold,
which defaults to 110 °C. If necessary, changing the temperature threshold is possible via
THERMAL LIMIT.
The power amp, however, is protected against thermal overload at all times, independent of
the indication.
NETWORK
This indicator shows whether communication at the CAN bus interface is normal (green) or
when a problem exists (red). The power amp automatically detects whether commands from a
PC or another central control unit are missing and signals the problem via the Communication
Flag.
WATCHDOG
AMPLIFIER
This indicator lights red when the power amp‘s watchdog has been activated. Press the CLEAR
button to clear the indication.
WATCHDOG
MODULE
This indicator lights red when the module‘s watchdog has been activated. Press the CLEAR
button to clear the indication.
CHANNEL 1...n
THERMAL WARNING This indicator lights red when the power amp's output channel temperature exceeds the pre-
set threshold. The power amp, however, is protected against thermal overload at all times,
independent of the indication.
PROTECT /
REDUCTION
When the red PROTECT / REDUCTION indicator lights, one of the internal protections (thermal
overload, short-circuit, Back-EMF, HF at the output, etc.) has been activated.
PROTECTION MUTE
When the red PROTECT MUTE indicator lights, the signal path gets switched off. The amplifier
needs to be switched off to prevent power amplifier and connected speaker systems from
being damaged, this is indicated by the PROTECT and MUTE-LEDs being lit simultaneously.
