EMI produced lots of classical Quadrophonic LPs in the 70s, and I have quite a few, although I've only ever played them in stereo. It's just occured to me that since I now have an AV32R, one of the surround matrices may be compatible with the encoding. I've tried the TMA matrix, which seems just as heavy-handed as ever, whilst the ProLogic Music setting sounded ok. Was it just doing its usual stuff with stereo recordings, though, or was it making use of the SQ encoding? How can I find out? If it's not decoding SQ, does anyone know what else can be done to get it decoded. Hell, I don't even know whether you needed a special cartridge set-up, though I don't think this was the case. Any comments gratefully received.
