Corrective maintenance
possible cause diagnosis/procedure
audio source failure check the presence of input levels, and the current status of the MADI,
AES/EBU, and AVB signals. If no signal reaches the processor, inspect
the audio source for failure.
Reminder:
A digital audio source can meet the following failures: no clock, loss
of lock, invalid audio (validity bit), CRC error, bipolar encoding error,
data slip.
An AVB audio source can meet the following failures: switch/talker
failure, cable failure, disconnection or "stop streaming" requested by
AVB Controller, non-Avnu certied device in network.

Noise, level loss, distorted sound, white noise
possible cause diagnosis/procedure
AES/EBU audio source is connected to an
analog input
check the input signal cabling
gain value too high on the processor set an appropriate gain value on the processor channels
If there are fallback enabled, set an appropriate input gain value.
output gain value too high on the audio source set an appropriate output gain value on the audio source (refer to the
third-party documentation)
input switched to an analog fallback with an
incorrect input gain value
set an appropriate input gain value, and inspect the digital audio
source for failure
Reminder:
A digital audio source can meet the following failures: no clock, loss
of lock, invalid audio (validity bit), CRC error, bipolar encoding error,
data slip.
An AVB audio source can meet the following failures: switch/talker
failure, cable failure, disconnection or "stop streaming" requested by
AVB Controller, non-Avnu certied device in network.
audio source cable incorrectly plugged unplug/replug the cable on the audio source and the processor
audio source cable damaged replace the cable
incorrect settings on the audio source set appropriate parameter values on the audio source (refer to the
third-party documentation)
audio source failure inspect the audio source for failure
