Split Key Operation
A Split Key uses any key source other than a key derived from the
key fill (self key) or a key source pre-selected in user preferences
or a preset pattern. All other key sources can be used in a Split
Key. A Split Key can be used in all keyers, and in either standard
or layered mode.
A Split Key is set up by first selecting the key fill source on the Key
bus, then holding down the VIDEO KEY button or the AUTO
SELECT
button while pressing a second button on the key bus.
The second source provides the key signal. For AUTO SELECT that
key is the external key signal mapped to that column of crosspoint
buttons; for VIDEO KEY the key is the video signal mapped to that
column of crosspoints. Pressing a lit video key or Auto Select Key
button will illuminate the key source crosspoint.
When a split key is operational with an auto select key or a video
key, the SPLIT KEY indicator is lit.
Other Key Modifier Buttons
Pressing KEY OVER swaps the priority of the two keyers, KEY 1
and KEY 2.The KEY OVER button lights when the keyer subpanel
is delegated to the key that is over the other. It may be pressed
whether or not either keyer is on-air.
In Layered mode, the KEY OVER button does not light if the keyer
subpanel is delegated to either background keyer, but the button
still controls the priority of Keyers 1 and 2. It does not affect the
priority of the background keyers, which have a fixed priority of
background A over background B.
