SANSUI QRX-6500 4-CHANNEL RECEIVER This is the new
Sansui 08 regular matrix 4-channel rece'yer with ingenious Vario-
Matrix circuitry for increased separation and improved 4-channel
soundfield reproduction. Incorporating all the acclaimed features of
the legendary QR-6500, the new QRX-65OO goes this famed unit
one step better by taking the matrix 4-channel system to perfection.
It is, first of all, a combined 280 watt 4-channel amplifier, extremely
sensitive FM/AM stereo tuner and the new OS regular matrix decord-
er. But then it is also the most advanced means yet devised of
faithfully reproducing an original sound field in 4-channel, while it
retains the capability of decoding and reproducting all the significant
4-channel sources available in disc and tape today. The secret of its
startling stereo separation is the Vario-Matrix circuit. In a nutshell,
this circuitry takes advantage of various psycho-acoustic pheno-
mena such as the directional masking of-the weaker sound by the
strongest , loudest sound when several sound arrive simultaneously
at the human ears. At this time the Vario-Matrix actually controls

cient the separation among the sounds-favoring the loudest sound.
of course-in proportion to the difference in loudness. Or, in other
words, the Vario-Matrix clearly defines each sound source to improve
your 4-channel sound field reproduction. The QRX-6500 is drama-
tically new in other ways. too. Its exclusive built-in 2-4 Synthesizer
Encoder helps the 08 regular matrix system transform all 2-channel
stereo records, tapes and FM stereo broadcasts more effectively into
supreme 4-channel sound. Its Phase Matrix circuitry perfectly
decodes all SQ system records with excellent front-rear separation.
It also has an.extra set of discrete 4 versatility. Summed up, what the QRX-6500 will do to your music
is add inspired d'epth, delicate nuances and the remarkable sound
