Number Element Description
1 SIGNAL LED and
LIMIT LED There is a SIGNAL LED and a LIMIT LED for each channel of the
output stage:
•
The SIGNAL LED for a channel lights up green at approx.
30 dB below the manual override limit.
• The LIMIT LED will light up red if the dynamic audio limiter
of the output has been activated. This can occur if the
input signal is too high or if the output load is too great. In
this case, lower the input signal. In the event of a short-
circuit to the output lines, the output voltage will be
reduced until the output current falls below the limit
value. The output voltage can remain at this reduced level
until the temperature level causes the output stage to be
switched off.
2 PROTECT LED The PROTECT LED lights up red when an internal protective
circuit in the amplifier has been activated, for example in the
event of
•
Excessive temperature
• Power supply under voltage
• Battery under voltage
• Short-circuit at the amplifier output
If PROTECT is active, the amplifier channel concerned or all
amplifier channels are switched off.
3 REMOTE LED The REMOTE LED lights up green in the event of successful
data communication with the DPM 8016.
4 STANDBY LED The STANDBY LED lights up yellow when the amplifier is in
standby mode. Further information can be found in the section
entitled Supply voltage, page 22
5 GROUND LED The GROUND LED lights up red when a ground fault has
occurred at at least one output. The LED remains illuminated
even when the ground fault has been rectified. To deactivate
the LED, press the FAULT button (7) or use IRIS-Net. Further
information can be found in the section entitled Operation,
page 31
6 FAULT LED The FAULT LED lights up yellow when a fault has occurred in
the amplifier. The types of faults to be displayed via these LEDs
are configured in IRIS-Net. Further information can be found in
the section entitled Operation, page 31
