Pioneer wishes to thank you for deciding to purchase the
PL-SSDX, a direct drive stereo turntable. Please read this
manual carefully, as it covers proper operating procedures
and steps which will aid in obtaining maximum per-
formance from this fine piece of equipment.

FEATURES

DIRECT DRIVE

Troublesome belts and idlers are not used A DC servo
motor drives the turntable directly. Design of this system
limits transfer of vibration to the tonearm to an amazingly
low level. PL-SSDX gives performance a cut above that of
comparable record players, and is sure to satisfy the most
exacting audiophile.

ELECTRONIC SERVO CONTROL

Ambient temperature does not affect the speed of rotation,
thanks to special electronic circuitry which maintains the
motor speed at a constant value at all times. A touch of a
button is the only requirement for setting this circuitry into
operation. Speed switching is simple. Independent controls
are used for fine adjustment of 33-1/3 and 45 rpm speeds.
(Fine adjustment is effective within i2% of the nominal
speed.)

VERSATI LITY

PL-SSDX plays all four-channel records SQ, RM
matrix records and CD4 discrete records. Ordinary two-
channel stereo records played on PL-SSDX yield a mar-
velous four-channel effect. PL-SSDX is sure to satisfy your
listening requirements.

POSITIVE TRACKING

New design provides for simple adjustment of lateral
balance of an S-shaped, statically balanced tonearm and
includes an anti-ska ing device.

Stable tracking is guaranteed in all cases, including of
course four-channel record playing and the use of cartridges
featuring light tracking force.

STABLE OPERATION

A fully automatic mechanism linked to the function lever
provides extra smooth tonearm operation, automatic re-
turn, and automatic interruption. There is never any need
for concern over record or stylus damage.

NOVEL DESIGN

The outward appearance looks as well as turntable mecha-
nism performs, matching other contemporary. stereo
system. Controls are grouped on the right side, for con-
venience.
