Sansui QRX-3000


From the standpoint of 4-channel versatility and performance, the QRX-3000 is clearly a best buy in a quality 4-channel stereo receiver.

The ingenious Sansui QS regular matrix system with new QS vario-matrix and QS 4-channel Synthesizer combination is employed, as in the more expensive QRX models, to give it full 4-channel capabilities.

while its simplified design and modest cost earn it the attention of economy minded audio enthusiasts everywhere. As a 4-channel stereo control center for the home the QRX-3000 is complete.

The QS Synthesizer/Decoder section, powerful 100-watt integrated 4-channel stereo amplifier and FM/AM 4-channel stereo tuner sections are integral parts of its functional and attractive design.

Despite its modest power rating, this machine sounds really great.
