Audio Failure Alarm
If no audio is applied to the Omnia, the following messages will be transmitted on the RS-232 port
approximately twenty seconds after a successful boot up:
Flr : Audio failure: left input
Flr : Audio failure: right input
Flr : Audio failure: left output
Flr : Audio failure: right output
In the absence of an audio source, these "Audio failure" messages are normal. Note that the Omnia's audio
failure trigger level is –37.5dBFS, and the signal must remain at or below that level in order for the silence
detect algorithm to time out. It is possible to see these messages during normal programming if the audio
input level falls below –37.5dBFS and remains there until the audio fail algorithm times out.
Audio Restoration Alarm
Approximately five seconds after audio has been restored to levels above –37.5dBFS, the following
messages will be seen:
Flr : Audio restored: left input
Flr : Audio restored: right input
Flr : Audio restored: left output
Flr : Audio restored: right output
Note that it is possible for there to be audio Output failure messages but no audio Input failure message.
This means that the unit is detecting applied audio at its Inputs, but that there is no output from the DSP
chain.
From the perspective of signal flow, the Input meters follow the input level adjustment controls (Input
Menu). This is also where the input to the Input Audio Failure comes from.
