Input Config(uration) (signal format)
1. From within the Input Configuration submenu, press the button of the input
you wish to configure. The input’s number will appear on the LCD screen.
2. Rotate the Adjust knob to select the appropriate video format (RGB,
composite video, S-video, component video, or progressive component video)
for each input.
3. Repeat steps 1 and 2 as needed to configure each input.
An LED near each video connector indicates which input type is active. Select
“Yes” from the Autoselect #7 submenu to activate autoselection.
If the autoselect feature is on, the last input (input 7 if no slave is attached) is
selected, and video signals are present at all ports for that input, computer
video (RGB) will be selected as the default source.
Inputs are autoselected as follows:
• RGB input (highest priority),
• S-video input,
• composite video input (lowest priority).
The LCD will display Autoselect #7 if the System 7 is not set up for a slaved
switcher. If a switcher is slaved to the System 7, the LCD will display
Autoselect #10, Autoselect #12, Autoselect #14, or Autoselect #16, depending
on the size of the slaved switcher.
