32 DMX outlets were provided on the grid for the control of moving lights, color scrollers, additional dimmers etc. Distribution of DMX is accomplished by a matrix cross connect system.
Two architectural dimmer racks provide 12 additional dimmed circuits for remote shots in the hallway outside the studio and within the main control room.
Additional 3 x 2kw and 6 x 1kw dimmer packs were provided for temporary additional dimmed circuits in the studio or mounted on scenic units.
Dedicated main power transformers raise input voltage to the dimmers. The output is regulated by the dimmer to insure 120 volts at each pigtail, near or far. These transformers also insure isolation of nearby office power panels from any harmonics generated by the operation of this large number of dimmers.
