This poster advertises the Japanese electronics manufacturer Sansui's QS Vario Matrix. "Sansui developed the QS Regular Matrix system, which made it possible to transmit four channel Quadraphonic sound from a standard LP. The channel separation was only 3 dB, but because of the human way of hearing it sounded relatively good. In 1973, Sansui introduced the more advanced QS Vario Matrix decoder with 20 dB separation." - Wikipedia
