When it is On, you can adjust additional settings to control video Gain, Black Level,
Hue, and Saturation. When Off, the additional settings are hidden. Proc Amp
parameter settings are independently kept for each separate input: SDI 1, SDI 2, Fiber
1, Fiber 2, Composite, HDMI, and Component.
Note: Source Memory—Independent analog output timing values are kept for
all available output formats.
Proc Amp Gain Proc Amp Gain adjusts the video gain from black to 1.5 times luma in steps of .01.
Proc Amp Black Proc Amp Black adjusts the video black level from -20 IRE to +20 IRE in 0.5 steps.
Proc Amp Hue Proc Amp Hue adjusts the video color hue through 360 degrees (color wheel). Steps
