System 7SC • Installation 2-4
Power, video, and audio conections
With the exception of input 7 on the front panel, all input and output connectors
are on the rear panel.
Front panel inputs
Input 7 on the front panel accepts video and one audio input. Only one video
format and one audio port will be active at a time on the front panel.
The active input type (RGB, S-video, or composite video) can be selected via the
LCD menu (see chapter three, “Operation and Configuration”, for details), or, in
autoselect mode, the System 7 automatically detects the active video signal and
selects that video signal format. If all formats are active, the default will be RGB
computer video input. An LED near each video connector indicates which input
type is active.
