You are a few years older than me, but I remember in the early 70s, Sansui and other makers had quadraphonic receivers. I forgot about that until now.In 1975 my Fisher receiver was stolen and moving to Columbus a few months latter, I purchase a discounted quadraphonic, four channel receiver, at a distribution center. I don't think the concept ever took off. Anybody remember a FM station broadcasting in that mode/band? I think the receiver used a internal skewed equalizer per channel to give the four channel depth effect...not certain though.
From the Web:
- 4-Channel Output: They contain four distinct amplifier sections to power four speakers, placing the listener in the literal center of the soundstage.
- Built-In Decoders: They feature specialized built-in decoders (like SQ or QS) designed to extract four channels of audio from encoded quadraphonic vinyl records or 8-track tapes
Quadraphonic sound was essentially an audio marvel before its time. It ultimately failed in the late 1970s because of competing and incompatible record formats, expensive equipment, and a lack of mainstream content
