Model 1200 Overview
aux buses automatically select the manipulated key and fill inputs
returning from the DPM. The aux buses then apply the
manipulated key and fill signals to the mixers. 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 digital, and parallel digital outputs
