Table 3.1.1: Troubleshooting Alarms
Alarm Name Trigger Conditions Clear Conditions Troubleshooting
AES1/2 Left Low Audio
The AES1/2 Left audio input level has fallen
below the user configured low audio
threshold for longer than the user configured
timeout.
The AES1/2 input must be configured as the
main audio source in the active preset for this
alarm to trigger.
The Main Audio Low Audio Alarm must be
enabled in the active preset for this alarm to
occur.
The presence of this alarm will cause a switch
to the backup audio source if configured in
the active preset.
This alarm will clear immediately when the
AES1/2 Left audio input level has increased
above the configured threshold.
Performing an alarm reset will clear this
alarm and reset the timeout.
Clearing this alarm will cause a switch back to
the main audio source if the transmitter was
previously operating on the backup source.
Check the audio feed connected to the
AES1/2 input. The most likely cause of
this alarm is an interruption in audio
distribution to the transmitter.
Verify that the threshold level
programmed in the active preset is
below the normal audio input level by
checking the AES1/2 Left meter.
Verify that the configured timeout is long
enough to cover any silence or dips in
signal level.
AES1/2 Left Low Backup Audio
The AES1/2 Left audio input level has fallen
below the user configured low audio
threshold for longer than the user configured
timeout.
The AES1/2 input must be configured as the
backup audio source in the active preset for
this alarm to trigger.
The Backup Low Audio Alarm must be
enabled in the preset for this alarm to occur.
The presence of this alarm will prevent a
change to the backup audio source if
configured in the active preset.
This alarm will clear immediately when the
AES1/2 Left audio input level has increased
above the configured threshold.
Performing an alarm reset will clear this alarm
and reset the timeout.
Check the audio feed connected to the
