Transition Controls and Operation

Second Press (and Subsequent) Transitions

During a preroll, a repeat press of the

PreRoll/Transition

button forces the

Preset bus to begin the transition.

■

First half of Fade transition: Pressing the

PreRoll/Transition

button again

forces the first half of the transition to complete. The Program output is
held in transition matte/silent until the newly transitioned source is
ready to air, and the

PreRoll/Transition

button is released.

■

Second half of a Fade transition: Completes second half of the Fade.

■

Mix transition: Pressing the

PreRoll/Transition

button again forces com-

pletion of the transition.

Hold Transitions

During a Fade type transition, you can hold a transition in transition
matte/silent by pressing and not releasing the

Preroll/Transition

button. The

Program bus is set to transition matte/silent and is held there until you
release the button.

Preroll Transitions Summary

Pressing the

PreRoll/Transition

button again after the actual video/audio

transition has started (regardless of how Transition Now is configured) has
the following effects:

■

For fade-fade (while fading down), cut to matte/silent. Hold in matte
until the

PreRoll/Transition

button is released, switch Preset sources to the

Program bus, then cut the Program bus to on-air.

■

For fade-take (while fading down), cut to matte/silent. Hold in matte
until the

PreRoll/Transition

button is released, switch Preset sources to the

Program bus, then cut the Program bus to on-air.

■

For fade-fade and cut-fade (while in fade up mode), immediately set
the Program bus to full gain.

■

For mix transitions, immediately complete the transfer of Preset
sources to the Program bus at full gain.

If flip/flop operation has been configured as enabled:

■

For mix transitions, Preset bus output cuts to the previous Program
output when the transition is complete.

■

For all other transition types, Preset bus output cuts to the previous
Program output as soon as Preset video/audio first appears on
Program output.

Preroll/Transition can affect main audio/video sources and/or AP 2–4
sources delegated for AFA operation. AP 2–4 details are described in the
Installation and Service Manual.
