Audio Failure Alarm
If no audio is applied to the Omnia, the following messages will be transmitted next on the RS-232 port,
approximately twenty seconds after 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 happens to fall
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.
