Masks Subpanel

Masks Subpanel

The Masks subpanel (Figure 2-16) services and controls all video

key masks in the switcher. A mask is a control signal used to

modify a key signal. Delegation of the subpanel allows it to

control any of the masks. Buttons and knobs are provided for

controlling mask position and aesthetic features.

Mask Delegation

Pressing one of the M/E or DSK Mask Delegation

buttons selects the corresponding mask generator.

Only one button can be on (high tally) at a time;

pressing a button de-selects the previous button

(lamp turns off).
