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.
