Description
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.
