Wipe Operations
Fade to Black
You can cut, wipe, or fade the switcher output to black at any time
by simply pressing the
PST BLACK button on the Transition
Subpanel. Then, pressing the CUT button cuts to black, while
AUTO TRANS or a Lever Arm transition will do either a mix or
wipe to black depending on the delegation status on the
Transition Subpanel.
The transition to black takes precedence over the entire output of
the M/E. Therefore everything will go to black regardless of panel
delegation.
When black is reached it is automatically selected on the A Bus
regardless of which crosspoint button it is mapped to. (If it is not
mapped, all buttons will be unlit.)
To transition from black:
1. Make a transition using cut, mix, or wipe.
– OR–
2. Cut to a new source on the A Bus.
NOTE: If you cut on the A Bus, any keys that would have transitioned
‘ON’ are dropped.
