Abstract: A server stores audio and coordinated video digital files in a library, and upon requests supplies individual files to multiple dedicates processors under sole control of the server. Music files have separate vocal and specific instrument channels. The processor supplies single channels to amplifiers and speakers having controlled frequency ranges capable of reproducing only the frequencies on the individual channels. Images from the video files are projected on screens around and above an audience seated on swivel chairs. Coordinated sounds emanate from speakers distributed over the screens. Bus-like wiring extends, from the processor. Individual speaker wires connect to ends of bundled conductors.
