Section 2— Control Panel Descriptions
Mask Delegation
Pressing one of the delegation buttons selects one of 
the mask generators. Only one button can be on at a 
time. 
INHibit MASK
 delegates the mask subpanel controls for adjusting 
the inhibit mask. The actual selection of mask inhibit is performed 
on the keyer subpanel (see the 
MASK INH
 discussion under the 
Keyer panel description).
FORCE MASK
 delegates the mask subpanel controls for making 
adjustments to a forced mask. The actual selection of force mask is 
performed on the keyer subpanel (see the 
FORCE MASK
 
discussion under the Keyer panel description. 
Auto delegation of the mask subpanel may occur when other 
buttons on the control panel are pressed. (Refer to the Auto 
Delegation discussion earlier in this section.)
Mask Source Selection
The top row of buttons (excluding
 MASK INVert
) select sources 
that determine the shape of the mask. These buttons are mutually 
exclusive and one is always active.
BOX
 uses a rectangular box generator for the mask. The box is 
completely independent of the wipe systems. The four knobs at 
the top of masks subpanel determine the position of the four sides 
of the box. The box mask has hard edges. Each keyer has its own 
box, so it is possible to have up to six differently sized box masks 
in use at a time. 
PRI WIPE
 selects the primary (transition) wipe generator to 
produce the mask. The primary wipe generator in the same M/E 
provides the mask signal. Wipe Subpanel controls select the 
pattern, size, position and edge softness.
