Stage Command System

PRG set a new standard for stage automation in 1988 when it introduced the patented Stage Command™ motion control system on Phantom of the Opera. The PRG Stage Command System (SCS) gives designers and operators the reliability to execute even the most complex motion control cues with accuracy, repeatability and unparalleled attention to safety. In the ever-expanding scope of scenic and automated elements, SCS offers the clear solution for today’s demanding performance environments.

The cue-based SCS software allows seamless transitions in full view of the audience and creates a world of possibilities for designers. At the core of the Stage Command System are four main components designed to work as a system or as individual products. Complete and accurate control is provided through the proprietary PRG Commander™ console; the SCS PLC Cube (Programmable Logic Controllers) provides a Go/No Go safety check prior to executing a cue; and the SCS Drive Racks house the individual drivers that send control signals to the motion effects.

Finally, the wide range of effects controlled include the SCS Winches, a standardized line of winches, and the SCS Turtle Rotator, which brings rotational motion to a wide range of scenic elements. SCS can also control motors, chain hoists, scenic deck dogs, and traveler track systems.
