5 The Audio Mute for both DVB-S C/N Margin (dB) and DVB-S2 C/N Margin
(dB) sets the DVB-S and DVB-S2 Carrier to Noise margins, in dB, below the
audio outputs that will be muted. The receiver uses these thresholds to
determine when to mute the audio in the event of a noisy, poor, or loss of signal
condition. The adjustable operating range is -30.0 to 30.0 dB. This setting must be
below the respective Restore value. The default setting is 0.0.
Note: The Enable Threshold Muting check box must be checked for these
settings to be active.
6 The Audio Restore for both DVB-S C/N Margin (dB) and DVB-S2 C/N Margin
(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.
Note: The Enable Threshold Muting check box must be checked for these
settings to be active.
