The QRX-6500 is an impressive instrument, specifically designed for those who demand no nonsense professional quality in a home 4-channel stereo receiver.
Its broad range of unique features, unlimited power, flexibility and superb tonal quality make it the finest 4-channel receiver Sansui makes today.
First of all, the QRX-6500 is a complete 4-channel stereo control center. Its functions can be divided into three major areas; the Sansui QS 4-channel Synthesizer and Decoder, the 4-channel, 280-watt integrated amplifier section, and the super-sensitive stereo FM/AM tuner.
At the heart of the 4-channel QS Synthesizer and Decoder section is the team of circuits which together make up the new Sansui QS Regular Matrix decoder with QS vario-matrix.
This, with the built-in discrete 4- channel auxiliary inputs and control capabilities, adds up to total 4-channel stereo versatility.
The standard Sansui 4-channel Synthesizer/Decoder Control, a five-position rotary control located on the front panel, enables the selection of two different QS Synthesizer modes (Surround and Hall), two QS regular matrix modes (Surround and Hall) as well as the additional Phase Matrix mode for decoding SQ records.
