Sansui QRX-7001


The Sansui QRX-7001 incorporates a QS synthesizer circuit to reorganise conventional 2-channel stereo signals and create a 4-channel sound field.

The built in QS regular matrix system 4-channel decodes 4-channel records and tapes encoded with the regular matrix system such as the QS system, and their broadcasts, to reproduce them as a perfect 4-channel sound field.

The built in Phase Matrix circuit, featuring Sansui's own front-back logic, decodes records and tapes encoded with the SQ system to properly reproduce them in 4-channel stereo.

The new Sansui improved CD-4 demodulator makes it possible to reproduce CD-4 4-channel records, with increased inter-channel separation.

re: QRX-7001

I have had a QRX-7001 since 1976 when I purchased it new while I was in the Army & stationed in Germany. I boxed it up about 15 years ago, and had not used it until my son in law recently expressed an interest in it. I took it out, and hooked it up, but even though it worked there were a few lights that no longer did, and some speaker conditions didn't seem to work either. I had it reconditioned to like new for less then I paid for it originally, and gave it to my son in law for Christmas. It sounds as good, and works like new. He is pleased to have it, and I am glad it has gone to someone who will appreciate it & care for it as I did. Next I will probably bless him with my four ESS AMT-5 speakers, but they need to be re-coned first.

I had the qrx 5500 a few years ago, and loved the thing!
