 A 4-channel reel-to-reel tape unit from the 1970s, one of the few ways to achieve true 4-channel sound at home |
Quadraphonic 8-Track was a discrete 4-Channel Tape Cartridge system announced by RCA Records in April 1970 and introduced in Sept. 1970, and first called Quad-8 (later shortened to just Q8). The format was almost identical in appearance to stereo 8-tracks, except for a small sensing notch in the upper left corner of the cartridge. This signalled a quadraphonic 8-track player to combine the odd tracks as audio channels for Program 1, and the even tracks as channels for Program 2. The format was not backward compatible with stereo or mono players – although quadraphonic players would play stereo 8-tracks, playing quadraphonic tapes on stereo players results in hearing only one-half the channels at a time. Some stereo (two-channel) 8-track players simulated quadraphonic sound through the upmixing of stereo 8-tracks, but these were not true quadraphonic 8-track players.
