The transition type can be changed when the M/E has reached its first
preset black stage, allowing for example a wipe to and a mix from preset
black. While in preset black, the key ON indicators report the states the
keys will have when the second transition command completes. The keys
involved can be changed at this time, if desired. The source on the PST bus
can also be changed while in the preset black stage.
A preset black transition can be canceled by pressing the Preset Black button
a second time. If cancelled while at the preset black stage, the system will
switch back the original signal. Pressing a source button on the PGM bus
will also cancel a preset black transition. The source pressed on the A bus
will immediately be placed on air without any keys, even if the next transi-
tion had specified key changes.
Transition Preview
The transition preview feature allows a main transition to be previewed
without affecting the program output. A transition preview cannot be per-
formed if the Transition Lever Arm or main transition is off limit, if an auto
transition is in progress, or when Preset Black has been selected.
Pressing Trns Pvw routes the main transition video to preview output and
disables program transitions on that M/E, leaving the existing program
output unchanged. Pressing
Auto Trans or moving the Transition Lever Arm
with Trns Pvw active will show the transition only on preview, allowing the
setting of wipe parameters or adjusting auto transition times before actu-
ally performing that transition. Transition preview overrides whatever
preview mode is currently selected.
Transition preview may be canceled at any time by pressing the lit Trns Pvw
button. If an auto transition preview is in progress, it will be aborted. If the
transition lever arm was used for the transition preview, canceling the
preview part way through will cause the lever arm to resync by recalcu-
lating the resting lever arm way to complete the transition in the direction
of the arrow. Moving the lever arm in the opposite direction allows to
resync the arm to an end position without affecting the output signal.
Transition Rates
Auto transition rates are set using the Trans Rate button and keypad located
on that Effects subpanel.
When the Trans Rate button is pressed, the Auto button in the Main Transition
subpanel and the four Key 1-4 Mix buttons and the Auto button in the 2nd
Transition Subpanel will flash and the Effects readout prompts for the rate
to be set.
