TBC Card Controls
Push buttons on the ES-2200T unit can have up to three control functions associated with them. Primary functions are
in Black. Secondary functions are in Blue. Shift functions are in Italic.
Proc Amp
Proc Amp controls are applicable to TBC cards. The Proc Amp controls are VIDEO LEVEL, BLACK LEVEL,
CHROMA LEVEL, and HUE LEVEL.
VIDEO
The VIDEO LEVEL button selects video level control for the shaft encoder. Changing the video level effects the
overall amplitude of the processed video signal, resulting in a change in the displayed picture contrast.
BLACK
The BLACK LEVEL button selects black level control for the shaft encoder. Changing the black level effects the DC
level of the processed video signal, resulting in a change in the displayed picture brightness.
CHROMA
The CHROMA LEVEL button selects chroma level control for the shaft encoder. The chroma level control changes the
color saturation of the processed video signal.
HUE
The HUE LEVEL button selects hue level control for the shaft encoder. The hue control changes the phase of the
processed color subcarrier, which effects the tint of the displayed picture.
