Thank you for your purchase of Pioneer Model PL-
61. You will get many years of pleasure from this
top-quality brushless low-speed DC Hall motor-
equipped stereo turntable. Please read this manual
and the directions indicated.

These instructions also apply to a variety of PL-61
supplied without a phono cartridge for the benefit
of using your favorite cartridge. Any standard car-

FEATURES

LOW-SPEED BRUSHLESS "HALL" MOTOR

Model PL-61 is equipped with a brushless low-speed DC
motor which utilizes Hall" elements instead of brushes.
(The production of these elements, based on a vacuum
vapor coating process, is a Pioneer development.) As the
motor mns at only ten times the revolutions of the turn-
table, speed reduction is greatly simplified, resulting in a
remarkable reduction of vibrations. The drive system is the
tried-and-true Pioneer belt drive. This and the absence of
brush noise put this model in the class of professional
record playing equipment.

ELECTRONIC SE RVO CONTROL

The turntable Speed is maintained constant by an elaborate
electronic servo control circuit with a frequency generator.
Outside factors such as the room temperature, the load, etc.,
cannot affect the turntable speed, as it is automatically
kept at the correct rpms by the servo-controlled motor.
What's more, switching from 33 to 45 rpm is also done
electronically and without vibration-prone mechanical parts
The turntable speed can be finely adjusted within a range
of 1-4% at both 33 and 45 rpm. This feature is very useful,
for example, when you wish to play an instrument along
with a record.

EASY, ACCURATE SPEED ADJUSTMENT WITH
STROBOSCOPIC PATTERN

The built-in fluorescent lamp and the stroboscopic patterns
on the outer platter rim indicate accurately when the
platter is revolving at the rated speed - 33-1/3 or 45 rpm.
This permits records to be played at exactly the speed they
were cut at.

S~TYPE TONEARM WITH LATERAL BALANCE
WEIGHT AND ANTI-SKATING DEVICE

Supported by ultra-sensitive bearings, the S-type tonearm
can trace all recorded information with accuracy and at
very light tracking forces. To maintain optimum tracking
conditions at all times, the arm is equipped with an easily
adjustable lateral balance weight and an equally convenient
anti-skating device. The arm of course accepts all standard
pickup cartridges.

tridge can be attached. In such cases, also observe
the instructions furnished by the cartridge manu-
facturer.

ANTISKATING EFFECTED BY MAGNETIC
FORCE

Other than conventional anti-skating devices (which usually
apply the required outside force by a weight suspended
from a thread), this newly developed Pioneer system utilizes
the attraction and repulsion of two magnets. This permits
the precise required force to be applied irrespective of
temperature variations 'and friction, and also simplifies the
necessary adjustment considerably - simply turn the adjust-
ing knob.

HIGH-QUALITY MAGNETIC CARTRIDGE SUP-
PLIED

The supplied phono cartridge (Pioneer model P050) is an
induced magnet type of excellent compliance, IO-25,000Hz
frequency response and over 25dB channel separation.
Equipped with a 0.5 mil diamond stylus, it provides long
service life while reducing record wear because of its excel-
lent tracking at very light forces.

VERSATILE, CONVENIENT AUXILIARY FEA-
TURES

The tonearm is raised and lowered by simple pushbutton
action, saving both stylus and record wear. When using a
cartridge other than the supplied one, the stylus overhang -
an important factor for perfect tracking geometry - can be
adjusted precisely with the overhang scale. The dust cover
stays open at any angle for convenient operation. The turn-
table rests on height-adjustable feet with shock absorbers
which help prevent howling. For accurate horizontal posi-
tioning of the turntable, a level is built in.

STYLED TO APPEAL TO PROFESSIONAL
TASTES

The walnut-finished, silk-smooth cabinet and the dark
motor panel and platter give a visual indication of this tu rn-
table's professional standards and precision.

INSTALLATION

Install the PL-61 with the following points in mind:

0 The place must be well-ventilated and free from humidity
and dust.

0 The unit should not be exposed to direct sunlight.

The unit should not be placed near a source Of heat.

0 The unit should be placed as far from the speaker systems
as possible.

TYPICAL STE REO SETUP

'lhe PL-61 is a top-quality turntable and should be combined
with other top-quality components, The drawings show a
typical installation and the relationship of turntable, stereo
amplifier or receiver, speakers, or stereo preamplifier, stereo
power amplifier, etc. (Figs. 1 and 2)

LINE VOLTAGE

Confirm the line voltage of your house current before turning
the power on, because your PL-61 may not be conditioned
for operation with the local line voltage. The LINE VOLT-
AGE SELECTOR PLUG, provided inside the wooden base,
can be seen when the bottom plate is opened (Fig. 3). The
PL-61 is set for 240V operation when shipped. If the house-
current voltage in your area in not 240V, pull out the line
voltage selector plug and put it back as shown in Fig. 3 for
operation on. 220V, 130V, 120V, or 110V.
