Proc Amp Controls
Processing amplifiers are built into the Model 1200. When you
double press any video or key crosspoint or press the
[PROC AMP]
top level menu button, the Proc Amp menu opens, and the
following video color correction controls become available:
■ Hue
■ Chroma Saturation
■ Luminance gain
■ Luminance offset
■ Chroma U offset
■ Chroma V offset
These settings are stored in memory for each crosspoint column.
So you can set the levels once for a particular crosspoint, and the
switcher will always recall those levels when you select that
crosspoint or any other crosspoint in that column.
You can adjust the proc amps for a crosspoint as follows:
1. Double press the desired [CROSSPOINT] button to bring up the
Proc Amp menu.
2. Adjust the soft knobs in the Proc Amp menu to obtain the
desired color correction. If you want to return to the default
levels at any time, press the
[CLEAR PROC AMP] soft button in the
lower left corner of the Proc Amp menu.
The proc amp settings will be remembered and recalled
whenever you select that crosspoint or any other crosspoint in
the same column.
