Master Q V6 System

MANUFACTURER DESCRIPTION
Originally cue lights were simply a signal light controlled by the stage manager / conference producter, to send cueing signals to the speakers or crew, AV technician to move forward on a 35mm slide presentation (before that to signal an actor to walk on stage!).  Qlites and headsets were, and still are, the standard way to tell speakers and crew when an action is needed.  But now  USB control is used to directly control many computer platforms be it PC, MAC, LINUX or indeed any other USB enabled device.
