Uncompromising quality is the key factor in the design concept of the QRX-5500.

It's a full-fledged 4-channel stereo home control center with all the advantages of the very latest electronic technology in the form of its all-stage direct-coupled OCL pure complementary power amplifier.

What's more, it offers excellent performance, high fidelity performance of the highest standards, and Sansui reliability.

Sansurs revolutionary 4-channel audio developments, as exemplified by the QS regular matrix system with QS vario-matrix and the famed QS Synthesizer, is combined in this powerful 220-watt 4-channel amplifier and sensitive FM/AM stereo tuner to enable you to enjoy any and all stereo and 4-channel program sources in realistic 4-channel reproduction.

As in all models of the new Sansui QRX series, the basic secret of the QRX-5500 is its QS 4-channel Synthesizer and Decoder section, a team of circuits which together make up the new Sansui QS regular matrix decoder with QS vario-matrix.

The Synthesizer/ Decoder Control on the right-hand side of the front panel enables you to select any one of five different 4-channel reproduction modes, including Phase Matrix for decoding SQ encoded records.

There's also the extra excitement of hearing your favorite 2-channel music sources transformed into authentic 4-channel sound by the Sansui QS Synthesizer, now greatly enhanced thanks to the OS vario-matrix technique.

This, with the built-in discrete 4-channel tape and auxiliary input circuits adds up to full versatility in all 4-channel formats.
