System for providing multi-channel supply to four-channel stereo headphones

摘要

the invention relates to a system for providing multi-channel supply to four-channel stereo headphones and an electronic signal processing unit which, in principle, regenerates from a two- or four-channel input audio signal a four-channel output audio signal with two direct/FRONT and two SURROUND audio signal channels, which are essential particularly for creating four-channel headphone surround sound and/or loudspeaker surround sound operation. This creates a four-channel audio signal supply system for four-channel surround sound headphones which is independent of the audio signal present, that is to say mono, stereo, multi-channel DOLBY surround sound or HDTV sound, etc., and is upwardly compatible for achieving the current stereo sound by means of stereo sound processors for multi-channel loudspeaker reproduction. In addition, a digital (four-channel, in the analog) cableless infrared audio signal transmission with three/five-pin upwardly compatible plug connection is provided.
