Rota-phonic system for stereo quadrophonic sound system

摘要

In a quadrophonic sound arrangement having a panel with a series of sound outputs connected to a series of speakers, and a series of sound channel inputs, a rota-phonic system which comprises a series of circuits interconnecting each input respectively to each one of the outputs. A continuously operated circuit control is interposed in said circuits for progressively changing the circuits for switching each channel input in a sequence form a connected speaker to the successive adjacent speaker, so that over a predetermined interval, each input is successively connected, one at a time, into each output. The circuits and circuit control includes a mechanical device for switching circuits. A modification includes a solid state electronic circuit between inputs and outputs with the circuit control including a series of trigger circuits and an associated trigger switch.
