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.
