Setting up Muting Threshold Controls

Proceed as follows to set up the muting threshold controls:
From the user interface of the D9865, choose Input > Satellite > Tuning Setup > Muting Thresholds.
Step 1
The Muting Thresholds page is displayed.
Check the Enable Threshold Muting check box to mute the transport stream and audio in the event of
Step 2
an unstable signal, poor signal, or no signal condition. The default is selected.
The Transport Mute and Restore for both DVB-S C/N Margin and DVB-S2 C/N Margin sets how the
Step 3
receiver reacts when the signal quality is severely degraded when using DVB-S or DVB-S2 modulation.
This allows you to set the transport C/N margin values for the receiver. The receiver uses these noise
values/settings as limits during normal operation to determine whether to mute the transport in the event
of a noisy signal, poor signal or no signal condition.
The Transport Mute is the lower limit for the transport C/N margin setting. The transport will be muted
when the C/N margin is below the mute setting for a nominal delay of 1 second. The delay is between
the time the condition is first detected and the time the transport is muted. The adjustable operating range
is from -5.0 to 20.0 dB. The default setting for Transport Mute is 0.0.
The Transport Restore is the upper limit for the transport C/N margin setting. The transport will be
un-muted (e.g., restored) when the C/N margin rises above the Transport Restore setting for a nominal
delay of 8 seconds. The delay is between the time the condition is first detected and the time the transport
is muted. The adjustable operating range is from -5.0 to 20.0 dB. The default setting for Transport
Restore is 0.1.
