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 unit 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 unit 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.
