changed. In normal mode, the Keyer Subpanel, located in each

In layered mode, four keyers are available – 
Key 1, Key 2, Background B, and Background 
A.

 indicator lamp lights when the delegated keyer is in

bottom of each keyer subpanel selects 
one of five keyer modes.

fixed at unity, clip fixed at 50%, and no S-shaping. The 

 button lamp (only) is illuminated when linear key is selected 

on the delegated keyer.
