The PL-115D is prelubricated at the factory, but the oil
may have dried up during shipment, so before use apply a
few drops of the accessory oil as described on page 10.
The PL-115D is a high precision belt drive turntable
designed for incorporation into a component type stereo
music system. It is recommended that you read these
Operating Instructions completely before using the turn-
table.

PL-115D FEATURES
Precision Belt Drive with 4-pole Synchronous Motor
Stable
rotation
of
the
30cm
diecast
aluminum
alloy
platter
is
maintained by the carefully engineered 4-pole synchronous motor
and belt drive system, The smooth running of the motor is
unaffected by fluctuations in line voltage and load, while even the
slightest vibrations from the motor are absorbed by the poly-
urethane belt. High performance is exemplified by the 0.07%
(WRMS) wow and flutter, and SOdB (JIS) signal to noise ratio.
Speed Detector Type Auto Return Mechanism
Faulty auto return is avoided by employing a speed detector
system in the mechanism to assure perfect operation at the end of
the
record.
By
pressing
the
RETURN
button
the
auto
return
machanism can also be used to interrupt a record during play, at
which time the tonearm is raised and returned to the arm rest
without risk of damage to the record.
High Sensitivity S-shaped Tonearm
The tonearm gimbal incorporates high precision angular contact
bearings, whose low vibration and friction ensure high sensitivity
together with long term reliability. Anti-skating and lateral balance
controls are included for optimum performance with high com-
pliance cartridges and light tracking forces, and the direct readout
of the tracking force is especially convenient when replacing the
cartridge.
Sophisticated Cabinet Styling
The baseplate is made from mineral solid, a new high density
material which combines excellent acoustic absorption properties
to prevent resonance with high strength and attractive finish. In
addition the elegant wood grain finish of the cabinet ideally
matches the high quality engineering of the PL-115D.
Numerous Additional Features
A host of additional features enhance the convenience and
performance of the PL-115D. Among these are a lightweight, high
rigidity aluminum headshell, low capacitance output cord, and
an oil-damped tonearm elevation mechanism to protect valuable
records and stylus. The interior of the cabinet is lined with
aluminum foil to screen out external electrical noise which is often
picked up from other household appliances, while motor and
external vibrations are also isolated by the double suspension design.

PIONEER
ATTACHING
THE
CARTRIDGE
Moving magnet (MM), moving coil (MC) and
induced magnet (IM) are the main cartridge types.
Although all of these can be used with the
PL-115D, select cartridges with weights between
4—10 grams. Refer to the cartridge operating
instructions for connection and handling. Since the
tonearm of the PL-115D is a universal type, your
optional cartridge with standard type headshell can
be attached with no problem. Install the cartridge
to the headshell according to the following steps.
1. When attaching cartridge to the accessory head-
shell, use the headshell, screwdriver, overhang
gauge, screws, nuts and washers supplied in the
accessory box (Fig. 4).
2. Connect headshell lead wires to the cartridge.
Observe lead wire color coding as follows.
White L (left channel)
Blue LG (left channel ground)
Red R (right channel)
Green RG (right channel ground)
3. Fit cartridge to headshell (Fig. 1), but do not
tighten the mounting screws yet.
4. Set the headshell into the accessory overhang
gauge as shown in Fig. 2. Adjust the cartridge
position so that the stylus tip is aligned with the
gauge line. Finally, tighten the cartridge mount-
ing screws, :
5. Install headshell on tonearm according to Fig. 8
on next page.
If your cartridge weighs over 8.5g, insert the sub
weight into the end of the tonearm shaft.
Refer to Fig. 3.

CARE OF YOUR TURNTABLE
CLEANING CABINET
Use a polishing cloth or a soft dry cloth to clean
dust from the cabinet and dust cover. Do not use
household waxes, solvents or sprays on or near the
turntable as they can mar the finish.
LUBRICATION
Mechanical noise or wow and flutter usually result
from a lack of lubricant in the rotating parts.
Lubricate
the
following
point
at
least
once
every
two months for normal use, and two to three times
if
the
turntable
is
used
very
frequently.
Before applying oil to the turntable, remove the
turntable platter as follows:
1. Remove the dust cover as described in “DUST
COVER” on page 7.
2, Return the tonearm to the arm rest and clamp
it, then protect the stylus tip with the stylus
cover,
3. Remove the drive belt from the motor pulley
with your fingers (Refer to Fig. 7 on page 4).
4. Lift the turntable platter straight up by inserting
fingers and thumb into the two openings (Fig.
19).
If the platter does not come away easily, try
jerking it, but take care not to damage any part
of the turntable.
5. Apply one or two drops of the accessory oil to
the
lubricating
hole
(Fig.
20),
being
careful
not
to get oil on parts such as the motor pulley, belt,
or inner rim.
NOTE:
If oil should adhere to the motor pulley, inner rim, or
are vette wipe it off with a cloth moistened with pure
alcohol.
Caution: Never use other solvents.
