This turntable is available in two models: one with a Pioneer phono
cartridge, and the other without a phono cartridge. The perform-
ance and functions are the same. These OPERATING INSTRUC-
TIONS are based on the former PL-520.
PL-520 FEATURES
Brushless DC Servomotor with Hall Elements
The PL-520 incorporates a high-precision phonomotor combin-
ing
control
circuitry
composed
of
semiconductors
with
Hall
elements in the brushless DC motor. The speed of the platter is
smooth
since
the
Hall
elements
guarantee
accurate
position
detection and the motor's winding current is controlled by transis-
tors. Another feature is the high inertia platter. Altogether, these
attractive features make for a signal-to-noise ratio of more than
73dB (DIN-B) and a wow and flutter of less than 0.03% (WRMS).
Two-motor, Full-automatic Turntable with Precision
Geared Motor Mechanisms
The lead-in and return of the tonearm are performed by a
special precision geared motor mechanism which does not affect
the speed of the platter at all. Furthermore, a speed detection-type
auto-return mechanism controls the tonearm for accurate and
stable operation every time it is returned to the arm rest.
Switches and Controls are Located at the Front for Easy
Operation
The two-speed fine-adjustment knobs for adjusting the speed of
the platter, the push-button speed selector switch, the size selector
for selecting the size of the records, the stop button, repeat button
and start button are all located on the front panel. This means that
you don’t have to lift the dust cover every time you want to make
an adjustment. [t also means that it is much easier to use this
turntable on a shelf or audio rack,
High-sensitivity Tonearm with Excellent Trackability
The newly developed, high-sensitivity S-shaped tonearm comes
with built-in lateral balance and anti-skating mechanisms and it
displays excellent tracking performance with a light tracking force
cartridge. There is a separate tracking force weight in front so that
you can easily change the tracking force even if you have mounted
your turntable in an audio rack.
Wide Selection of Accessory Mechanisms
There is a plentiful variety of accessory mechanisms including
an independent arm-elevation mechanism, a headshell stand for
conveniently storing a spare cartridge. a free stop-hinged dust
cover which allows easy attachment and removal, and large-sized
insulator feet.

LINE VOLTAGE
SELECTOR SWITCH
This turntable is equipped with a line voltage
selector switch which allows this turntable to be
used in locations where the power voltage is 110V,
120V, 220V or 240V.
Before your turntable is shipped from the factory,
the switch is set to the power requirements of the
turntable’s destination, although you should check
that it is set properly before plugging the power
cord into the outlet. If the voltage is not properly
set or if you move to an area where the voltage
requirements differ, adjust the selector switch as
follows:
1. Disconnect the power cord.
2. Provide yourself with a medium-sized screw-
driver. Insert the tip of the screwdriver into the
groove of the selector switch and turn it to the
voltage indication corresponding to the power
voltage of your residence.
You can tell when it clicks into place.

ATTACHING THE
CARTRIDGE
You can attach any cartridge to this turntable as
long as it weighs between 4g and 10g. Follow the
procedure outlined below for attaching the car-
tridge.
1.Take out the headshell, cartridge mounting
screws, nuts, washers and small-sized screwdriver
from the accessory box.
The screws come in three different lengths so
choose the screws according to the height of the
cartridge you intend to attach.
2. The terminals on the accessory headshell are
aligned as shown in Fig. 2. Check the location
and polarity of each of the cartridge’s terminal
pins and then connect the lead wires, taking care
not to get the polarities mixed up.

Do not solder when you connect the lead wires to the
cartridge. If the lead wire lugs are loose, use a pair of
tweezers
or
a
similar
device
to
push
in
the
end
lightly.
3. Attach the cartridge lightly to the headshell
using the screws, nuts and washers (Fig. 3).
4, Adjust the position of the cartridge so that the
stylus and the connector section of the headshell
are 49mm apart and tighten up the screws. Make
sure that the cartridge does not tilt to one side
when you attach it (see Fig. 4).

ATTACHING HEADSHELLS NOT MADE BY
PIONEER
You can attach headshells made by other com-
panies as long as the coupling portion has the same
dimensions as the headshell supplied with your
PL-520. However, you should check whether the
terminals on the other headshell are aligned in the
same way. When attaching, make sure that you do
not neglect to carry out the four steps described
above.

STEREO AMPLIFIER
CONNECTIONS
The PL-520’s phono cables and ground lead are
attached to the rear panel of the turntable. The
phono cable with the white plug is for the left
channel and the one with the red plug is for the
right channel. The thin wire with the Y-shaped
connector at the end is the ground lead. This
should be firmly connected to the ground terminal
on the amplifier (Fig. 11).
The way is which the phono cables are attached
will depend on the type of cartridge used. Read the
instructions in the booklet that comes with the
cartridge as well as the operating instructions of
the amplifier and connect the phono cables pro-
perly.
Finally, plug the power cord into the power outlet.
If this is carried out after the tonearm has been
adjusted,
the
platter
will
start
to
rotate.
Push
the
CUT button and stop the platter. The auto-play
mechanism is now set to stand-by.

UP
position.
The
arm
elevation
mechanism
is
independent
of
the
auto
mechanism
and
so
the
tonearm
will
ascend
and
descend
irrespective
of
whether
the
turntable
is
set
to
auto
play
or
to
manual
play.
This
is
a
convenient
function
since
it
allows
you
to
choose
just
the
tracks
you
want
to
hear
from
an
LP.
RELEASING REPEAT-PLAY MECHANISM
The repeat mechanism only is released when you
push
the
REPEAT
button
during
repeat
play
and
then
take
your
finger
off
the
button.
The
turntable
is then set to the normal auto play mode.
OPERATION PRECAUTIONS
Always set the record size selector before you
push the START and REPEAT buttons when
you want to set the turntable to the auto play or
repeat play modes. This is because the stylus will
not descend where you want it to descend if you
change the setting of the record size selector
while the tonearm is moving. You may also
damage the stylus and the record.
Always clean the stylus both before and after
playing a record with a soft brush and try to
make it a rule to clean the records with a good
quality cleaner.
When changing over the headshell, clamp the
tonearm to the arm rest so that the tonearm
shaft is not strained in any way.
Be careful not to make the turntable vibrate
while a record is playing since this can result in
damage to the stylus and record.
Do not force the tonearm closer than 40mm to
the center shaft or away from the arm rest. If
this distance is exceeded, you may damage the
internal mechanisms and render automatic ope-
ration ineffective.
Place only one record at a time on the platter. If
two or more records are stacked on the platter,
the stylus will not make proper contact with
the grooves, and this will impair the quality of
reproduction.
Do not disconnect the power cord while the
stylus is still in a record groove as this may result
in damage to the stylus and record.

ADJUSTING
STYLUS
DESCENT
POSITION
If the stylus does not descend onto the lead-in
groove on the record during automatic play, adjust
as follows:
1. Place a 30cm (12-inch) LP record on the platter.
2.Go through the operation for automatic play
once (refer to page 8), and check the level and
direction of the stylus’ deviation from the norm.
8. Return the tonearm to the arm rest, and then
turn and adjust the stylus descent-position
adjusting screw using the accessory screwdriver
(See Figs. 13 & 14).
@ When the stylus descends outside the lead-in
groove, turn the adjusting screw clockwise.
@ When the stylus descends inside the lead-in
groove, turn the adjusting screw counter-
clockwise.
e Each half-turn of the adjusting screw moves
the starting point about 6mm.
NOTE:
Be very careful not to damage the record and the stylus *
when you are adjusting the position of the stylus descent.

GENERAL
PRECAUTIONS
CABINET
When the dust cover or the cabinet is dirty or
dusty, wipe them clean with a polishing cloth or
soft cloth. Do not use furniture wax or bring the
turntable into contact with benzine, insecticides or
any other inflammable material since they will
corrode the outside of the turntable.
MOTOR WORKS PROPERLY AFTER PLATTER
IS MOUNTED
If the motor is run with the platter removed, the
motor will not operate normally and may seem to
have broken down. If, however, the platter is
mounted, the motor will rotate properly.
LUBRICATION
There is no need to lubricate the PL-520 since it
employs oil-less bearings in the rotating parts.
If the turntable is brought into the warm from
previously cold surroundings, or if the room
temperature rises suddenly, moisture will
form on the operating sections and the turn-
table will not be able to display its perform-
ance to the full.
If confronted with a situation like this, leave
the turntable in its new environment for
about an hour or try and increase the room
temperature gradually before operation.

replaced
by
grasping
the

and
pulling
it
away
from
the

of
the

pushing
it
into
the
receptacle. The correct replacement tip is
the PN-400. This may obtained from
your
Pioneer
dealer.
