Sony Turntables 1980 Catalog

Sony achievements in every aspect of
audio and video reproduction are
legendary. The company's success in
these fields is no aCCIdent. nor is it
recent. It arises from three sources.
First. the vast Sony research and engi-
neering facilities. among the most
SOphisticated in the world. Second. the
application of total-system technology'
in the design of every product. And
third, a commitment to translating this
approach into advanced instruments for
the home-at a cost within the reach of
the user. Sonys SIX new direct-drive
turntables are outstanding expreSSions
of Sony leadership.

Even the least expensive models. the
semi-automatic PS-T22 and the fully-
automatic PS-T33. boast the direct-drive
system. At their heart is Sony's remark-
able brushless-slotless (BSL) motor The
BSL design eliminates the motor cog-
ging inherent in most direct-drive
systems. The result is smooth, even
rotation. This rotation is monitored With
exqwsite preciSion by Magnedisc servo
control. Magnedisc senses the slightest
variations in turntable speed-and cor-
rects these variations before they can
affect the sound.

Sony's more expensive models take
this system one step further. They com-
pare the Magnedisc readings with a
stable reference frequency. generated
by a quartz crystal These are Sony's
quartz X-tal Lock turntables: the fully-
automatic PS~X45, X55. X65. and X75,

These Sony models incorporate out-
standing drive systems-with wow and
flutter below an amazing 0.025% on
even the modestly-priced PS-T22. But
total-system technology demands that
the entire record-playing system be
designed to the same standards as the
drive system. Sony's comprehensive re-
search has uncovered new ways to
improve sound quality. cartridge com-
patibility. and operating convenience.
These studies have led to the develop-
ment of new. low-mass tonearms;
smooth. silent tonearm automation: and
special. non-resonant cabinets.

Each of these Sony turntables boasts
a cabinet made of Sony 8qu Molding
Compound (SBMC) This specrally-de-
veloped. non-resonant material absorbs
the air-borne low-frequency sounds that
can often generate acoustic feedback
and howling'.

Sony's new tonearms accept the
Widest range of cartridges. including
the very latest. high-compliance types.
Sony's straight tonearm3~incorporated
on the PS-T22, T33. X45. and X55-
feature smooth bearings and
exceptionally low mass. With these
Sony turntables. you can take full
advantage of modern. light-tracking
cartridges.

The PS-X65 and X75 offer a maior
Sony innovation: Velocity Feedback. a
microprocessor-controlled tonearm
gwdance system. In the X65. Velocrty
Feedback controls all horizontal motion
of the tonearm: not only indexing and
automatic cycling. but also anti-skating
force and tracking itself. The X75 uses
Velocity Feedback for vertical as well as
horizontal motion. Not only can these
tonearms be safely matched to almost
any cartridge. but they also prowde
superior stereo separation, reduced
resonance. less record and stylus wear.
lower background n0ise. and reduced
intermodulation distortion

Sony's attention to detail extends to

For all their sophistication. these
turntables are quite easy to use and
surprisingly affordable. Sony, With its
vast and soohisticated deSign and
manufacturing facilities. is committed to
providing outstanding performance at
modest cost.

depth look at how these turntables
perform. and how they satisfy the needs
of mUSlC lovers the world over.
