Encoding Quad via simple Microphone placement as per this tiny article from the 70's.
Always found this a bit intriguing . I'm guessing some engineers experimented with this method.
FWIW one engineer actually encoded "naturalsurround" via stereo mics and produced a pleasing quad effect . I have the cd from "Audio Ideas Guide" with simple quadrant/soundfield speaker identification , and by gosh and golly it actually works --------as it pretty much should via the Tate 101a, when SQ is selected .
