Grass Valley 1200 Installation - Manual (Page 23)

Model 1200 Functional Overview
The aux buses automatically select the manipulated key and fill inputs
returning from the DPM and apply them to the corresponding mixer.
The mixers multiply the processed background and key signals to produce
mixed effects video. The effects video enters the downstream key mixers
where the DSK signal is mixed over the effects layer. The final output
signals then pass through output processing to the various analog, serial
component digital, and parallel component digital outputs.
