(dB) sets the DVB-S and DVB-S2 Carrier to Noise margins, in dB, above the
audio outputs that will be restored. The receiver uses these thresholds to
determine when to restore the audio after it has been muted. The adjustable
operating range is from -30.0 to 30.0 dB. This setting must be below the
respective Mute value. The default setting is 0.1.
