7.1 Understanding the Video Group Mode/Scaler Mode
This is a machine with an 18x1:3 switcher for the Scaler, as well as individual
video switchers for the five Video Groups: composite video, s-Video,
component video (RGB or YPbPr), DVI-D and VGA.
When the
VP-725DSA
is in use, both modes operate simultaneously, as well
as independently. That is, the Scaler output is available even when switching
in the Video Group mode, and visa-versa (except for DVI: once a DVI input
is selected in the Scaler Mode, that DVI input selection cannot be changed in
the Video Group Mode).
In both the Video Group and the Scaler Mode, you can adjust

the Audio
Level (Mic In).
