Configuring the Loss Of Signal (LOS) Matte
If an on-air source is lost, the Loss Of Signal (LOS) matte is provided to
immediately go on-air in its place. When an LOS matte is active, the cross-
point corresponding to the active LOS matte on the Program bus will flash
high/low tally continuously.
Configure the LOS matte as follows:
1. Disconnect one of the video input sources on the rear of the A/V/C
Processor Frame.
2. On the MMCP Preset bus, select the crosspoint button mapped to the
disconnected video input source. The selected
PST button high tallies. A
default LOS Matte of black is displayed.
3. Set up an LOS Matte to fit your site requirements by adjusting the Hue ,
Saturation , and Brightness controls on the Keyer Control subpanel (while
holding down the Mode/Function button).
4. Re-connect the video source disconnected in Step 1 .
Note LOS Matte values are reported as read-only values in the General Parame-
ters form in Configuration Manager.
