Assigning a Source to the SRC Button
The Source (SRC) button on the Preview Bus Module can be programmed with a specific video
source. When the SRC button is selected, the video source that is assigned to the button is fed out
of the preview. This source overrides the preview video but is not taken to air with the next
transition. When the SRC button is de-selected, the video previously being fed out of the preview
is restored.
Use the following procedure to assign a video source to the SRC button:
1. Press and hold the SRC button on the Preview Bus Module. The video source that is
currently assigned to the button will light up on the Preset Bus of the Program/Preset
MLE.
2. Select a source on the Preset Bus of the Program/Preset MLE to assign that video
source to the SRC button.
This completes the procedure for assigning a video source to the SRC button.
