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

 button or the

 button while pressing a second button on the key bus. 

The second source provides the key signal. For 

 that 

key is the external key signal mapped to that column of crosspoint 
buttons; for

 the key is the video signal mapped to that 

column of crosspoints. Pressing a lit 

 or 

 

button will illuminate the key source crosspoint. 

When a split key is operational with an auto select key or a video 
key, the 

 indicator is lit. 

Pressing

 swaps the priority of the two keyers,

 

and

.The

 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

 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.
