Press the DSK 1 keyer selection button, turning it on.
This delegates the downstream keyer control section to DSK 1.
When inserting a key, select the key fill and key source signals and make
any other required settings.
For more details of key signal selection and other settings, see the
section "Downstream Keys" (page 4-71).
Select the key transition type with the buttons (MIX, WIPE or DME) in
the transition type selection section.
Notes
• A DME wipe can be used only for one of the four downstream keys. If
a DME wipe is already selected for one of the other keyers, for example
DSK 2, then first change the transition type for DSK 2 to wipe or
dissolve, then select DME for DSK 1.
• On a 3.5-M/E system, if a DME wipe is already selected for the
background transition or for one of the other keyers, then the DME
button in the downstream keyer control section does not operate.
