Sansui QRX-3500 Quadraphonic Receiver
Available at our LONG BEACH location.
Four Channel Receiver (1973-74)
The QRX-3500 has been conceived and crafted to lead the new generation of quality Sansui 4-channel stereo receivers.
Its distinctive styling and high performance specifications have already earned it critical acclaim from professionals and the public alike.
The overall design of the QRX-3500 is based around the new Sansui QS regular matrix system with QS vario matrix 4-channel decoder circuitry and the QS 4-channel Synthesizer.
This electronic ensemble works in concert with the 180-watt 4-channel stereo integrated amplifier and high-resolution FM/AM 4-channel stereo tuner sections for total 4-channel versatility in a medium-priced instrument.
A newly-designed Function control lets you select any one of five 4-channel modes (OS Synthesizer, QS regular matrix surround, QS regular matrix hall, and phase matrix) plus a conventional 2-channel position.
The QS Synthesizer creates an authentic 4-channel sound field from any 2-channel stereo source, while the positions for QS regular matrix system with new OS vario matrix circuit for decoding all QS and compatible matrix-encoded 4-channel program sources.
Records encoded with the SQ matrix system are heard in full 4-channel sound with the function control in the Phase Matrix position. In addition, there are two sets of discrete 4-channel inputs, adding up to total 4-channel capabilities in one complete unit.
