sound, the QS-500 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-500 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.
