Congratulations on joining the thousands of proud, satisfied owners
of quality stereo components from Sansui.

The Sansui QR-500 4-channel receiver incorporates Sansuis unique
QS Synthesizing/Decoding matrix (patents pending) that produces
a multi-dimensional sound field so enthusiastically received by many
audio experts as purely revolutionary. An instrument that literally
heralds the new age of 4-channel stereo sound reproduction, the
QR-SOO not only converts ordinary 2»channel stereo discs, tapes and
FM broadcasts into immensely richer 4-channel stereo sound, but,
working in the capacity of a decoder, restores any 2-channel material
encoded from four channels to its original fullvfledged 4-channel
status.

To enjoy dynamic life-like 4»channel stereo sound at its best, you
should be well acquainted not only with the operation of the various
controls of the QR'SOO, but with such matters as the proper
positioning of speaker systems. Read carefully the instructions
contained in this booklet, and you will be better prepared to take
full advantage of the advanced performance capabilities of this new
instrument for years to come.
