Sansui's history-making 4-Channel Synthesizer Decoder QS-1, the ingenious yet inexpensive Sansui instrument that magically transforms two channel stereo into a live four channel sound field. Two power amps needed. It's sounds like the classic receivers QRX-9001, QRX-7500. This unit is in best condition after restauration.
