Description
This is used to set the Audio channel
Cutoff and Restore C/N margin values
(limits) to mute audio when the signal
quality is severely degraded when using
DVB-S or DVB-S2 modulation.
The Cut Off is the lower limit for the
audio C/N margin setting. Audio will be
muted when the C/N margin is below the
Cutoff setting for a nominal delay of 4
seconds. The delay is between the time
the condition is first detected and the time
the transport is muted.
