Selecting and Displaying SqueezeBack Effects
To select a SqueezeBack effect:
1. Press and hold the Mode/Function button.
2. Press the SQB button located in the bottom left of the User subpanel. The
next SqueezeBack effect will be selected and displayed.
3. Release SQB and then press again to view the next effect.
The SqueezeBack effect must be showing on the LAP monitor (that is,
selected and active), and must not be on-air.
Releasing the Mode/Function button exits the SqueezeBack effect selection.
The tally of the SQB button does not change. Releasing the SQB button
causes no change of tally if it was pushed while the Mode/Function button
was held down.
Making SqueezeBack Transitions
The SqueezeBack effect can be cut on/off-air, just like a key. The SQB button
is toggle action, if it currently tallies high (selected and active) or low
(selected and not active), on the next press and release it will tally off (dese-
lected).
1. Press the Next Transition Key button so that it tallies high.
2. Select SqueezeBack by pressing and releasing the SQB button.
3. If SqueezeBack is selected and active, the next transition will cause the
SqueezeBack effect to transition to air (if not currently on-air), or to be
removed (if currently on-air). When a transition occurs:
a. If the transition type is Take , the SqueezeBack transition occurs in a
three-frame transition.
b. For any other transition type, the Squeeze-back transition occurs at
the rate selected by the
Transition Rate .
4. Deselect SqueezeBack by pressing and releasing the SQB button.
SqueezeBack can occur simultaneously with background and key transi-
tions. If the SqueezeBack background signal becomes non-sync or is
dropped, the result is similar to keys becoming non-sync. SqueezeBack
tallies to off, any SqueezeBack effect on Program or Preset immediately
removes that effect.
