Sansui model QS-1 Quadphonic Synthesizer in excellent condition. This device allows you synthesize quadraphonic sound from any source. It is a line-level device. It does not provide any amplification. You must have 4 channels of amplification from a 4 channel amp, or two receivers, integrated amplifiers, power amps or any combination thereof. It has been serviced and includes a copy of the owner's manual.

This unit has the original factory protective plastic on the top, bottom and sides of the front panel.

From Sansui:

Here it is, Sansui's history-making 4-Channel Synthesizer Decoder QS-1, the ingenious yet inexpensive instrument that magically transforms two channel stereo signals into a breathtakingly live sound field.

An extraordinary stereo achievement, the QS-1 is having a profound impact on the entire world of stereo in two ways. First, it permits stereo enthusiasts to continue to use and enjoy their present 2 channel stereo equipment and program sources while moving into the new audio era.

And secondly, it is obviating the need for 4 channel equipment and program sources per se because, as distinguished audio technicians have attested, the QS-1 actually surpasses any 4 channel devices yet developed in terms of sound field brilliance.

This remarkable reproduction is accomplished through the use of an exclusive new decoding matrix which establishes more distinct images of original sound sources than ever before, and through a technique called phase modulation by which direct and indirect sound waves are fused to precisely duplicate the way they would be heard in concert hall surroundings.

In addition, the QS-1 so dramatically improves the smoothness and dynamic range of reproduced sound that even compact speaker systems can render sound as life like and powerful as that heard from much larger systems.

With the QS-1, the age of the multi dimensional sound field has arrived. Styled to match the elegance of other distinguished Sansui components, it can nonetheless be incorporated in any quality stereo system. For a very modest investment, the new audio age is yours to enjoy.
