Abstract: In a lighting console which provides outputs to dimmers which include master controls for at least two scenes and channel controls for each of a plurality of channels with the channel controls including at least a first and second scene preset potentiometer, the channel controls and master controls cooperating to allow presetting, and which also includes a buss, with one of the preset potentiometers for each of a plurality of the channels connected to the buss and an output from the master controls being used through suitable amplifiers to drive the buss, a plurality of nondestructive current limiting fault isolating devices are provided for each scene, each connected between the master and at least one of the preset potentiometers for that scene. As a result, the effects of a fault causing abnormal currents to flow which develops after the fault isolating means will not disrupt the operation of channel potentiometers connected to other fault isolating means. In addition, the console permits the separation of the assignment selection of potentiometers and the assignment indication of that selection. The console also includes distributed multiplexing devices which reduces the back plane wiring requirements in the console.
