Sansui QS-800


An instrument that heralds the new age of 4 channel stereo sound, the QS-800 converts your present collection of 2 channel stereo records and tapes, as well as FM stereo broadcasts, into 4 channels.

In addition, working in the capacity of a 4 channel decoder, it restores any encoded 4 channel material to its original full-fledged 4 channel status.

Simply add the QS-800 to your present 2 channel stereo system along with a second pair of speaker systems, and you'll instantly have a 4 channel stereo system to fill your room with the vibrant atmosphere of live performances with all their delicate nuances.

It comes complete with all the popular refinements of the best selling 120 watt QS-500, and then some of its own that Sansui has added for still greater convenience and versatility, such as rear channel Bass and Treble Tone Controls, separate Phase Switches for the rear left and right channels, Direction Switch, Power Limiter and so forth.
