Attracting most attention, though, was the Twin DMX Rotator. This adds DMX control of rotation speed and indexing (the ability to accurately and repeatably return a gobo to a known orientation) to the features of the Twin Rotator. The Twin DMX Rotator is also easy to integrate into existing lighting rigs with its ability to run from the 24V power supplies used for Rainbow or Chroma-Q scrollers, as well as from DHA's range of power supplies. All of the units feature a new belt-drive design, making them silent in operation - an important requirement for theatre productions.
