Precautions
Installation place
• Install this unit in a horizontal and stable place where the
unit is less subject to external vibration.
• Do not install this unit near a television or color monitor.
Keep this unit away from such devices as cassette decks
that are subject to magnetism.
Do not move this unit during playback.
Moving this unit during playback may cause needle jump, and
damage the needle and record thereby.
When moving this unit
For moving this unit, be sure to turn off the power after stop-
ping the platter and removing the record.
Next, unplug the power and phono cables and move this unit.
Avoid the following locations for installation.
• Locations exposed to direct sunlight
• Places subject to humidity and with less ventilation
• Places where are extremely hot or cold
• Places subject to vibration
• Places subject to dust
• Places subject to oil, steam, and heat (such as kitchens)
Do not put articles.
Do not put articles on this unit.
Lubrication
Do not lubricate this unit yourself because special oil is used
for the spindle.
Cleaning
• Usually, wipe the unit with a dry soft cloth.
When the dirt is hard to remove, dip soft cloth in detergent
diluted 5 or 6 times with water, wring it well, and remove
contaminants. Then, remove the moisture with dry cloth.
• Be aware that acrylic portions such as dust cover may be
damaged if the portions are rubbed hard.
• Be aware that printed or painted portions may be damaged
if the portions come into contact with alcohol, thinner, ben-
zine, insecticide, or the like. In addition, do not let this unit
contact a rubber or plastic form for a long time. That may
damage the cabinet surface of the unit.
• When using a chemical cloth for cleaning, read the caution
provided with the chemical cloth product.
• Be sure to unplug the power cable from the outlet before
cleaning.
Repair and adjustment
When repair and adjustments are needed, please ask the
dealer where you bought the unit.
To avoid heat emission
Do not place this unit on such device as an amplifier that may
emit heat. If the unit is installed on a rack, install the unit as
distantly as possible from where the amplifier is installed so
as to avoid heat emission from the amplifier and other audio
devices.
Dew condensation
Be aware that condensation may occur when this unit is
moved from a cold place to a warm place especially in win-
ter or when the temperature of the room where this unit is
installed is quickly raised with a heater or the like. It depends
on the condensation state, however, this unit can be used af-
ter disappearance of water droplets by turning on the power
and leaving the unit as it is for 1 to 2 hours to keep the unit at
room temperature.
Even in summer, dew condensation can occur if this unit is
directly exposed to cool air from an air conditioner. In such a
case, the installation place should be changed.

Features of This Unit
Belt drive
We have introduced a drive system in which motor-derived
noise is attenuated via a belt and smooth rotation is achieved.
Circuit configuration
AC synchronous motor is driven by sine waves coming from
32-bit microprocessor, which are DA converted and amplified
by a high-power audio amplifier.
Stroboscope
This unit is equipped with a reflective view type LED stro-
boscope that is useful for adjusting the rotation speed in a
precise manner.
High torque motor
An AC synchronous motor with high torque is adopted to
achieve precise and quiet rotation.
Heavyweight platter
The platter weighs 5.0 kg, which is machined from aluminum
metal to improve accuracy.

of moment of inertia has been
High rigidity main chassis
This unit uses an underslung vibration-damping structure ca-
pable of hanging internal main parts using machined alumi-
num plate with 15 mm in thickness as a base.
2
BELT DRIVE ANALOG PLAYER PD-171AL
Large-sized spindle
This large-diameter spindle is equipped with polyether ether
ketone (PEEK) bearing of ball bearing specification that pro-
vides stable rotation.
Floating mount
The power transformer and motor are floated from the main
chassis to isolate vibration to the top board.
Hybrid vibration damping
The bottom face of the cabinet has a hybrid vibration-damp-
ing structure made of wood and metal for resonance disper-
sion.
Large-sized insulator
This unit adopts a damper as an insulator that is a combina-
tion of rubber and spring, made from different materials to
isolate unnecessary vibration coming from an audio rack or
others.
Unnecessary vibration from the main chassis itself is also
suppressed.
LED stylus light
The detachable high-intensity LED stylus light is supplied for
operation in the dark.

Platter mount handle
Rubber belt
Motor pulley
Do not turn on the power until assembly is completed.
1. Installation of main body
Install the main body on a rack that is in a position as hori-
zontal as possible.
If the mounting position is inclined, rotate the insulators on
four corners of the bottom side to adjust the whole horizon-
tal balance.
Counterclockwise for up, and clockwise for down.
Exercise extra care to handle the platter because the platter
is heavy.
3. Belt wrapping
Firstly, wrap the belt around the turntable. Secondly, wrap
the belt that is wrapped around the turntable around the
pulley. (There is no difference between inside and outside
on belt.)
Rotate the turntable with your hand a few times, and check
to see that the belt is wrapped around the correct position
of the pulley.
2. Platter mounting
Engage the supplied platter mount handles in the platter,
align the center of the platter with the center spindle while
holding the handles, and engage them.
Be sure to use both hands to hold the platter and mount it
while using caution not to apply any unreasonable force to
the center spindle.

cover using the supplied hex wrench.
2. Mount the tone arm on the optional arm base.
3. Align the mounting holes between the tone arm-mounted
arm base and this product.
Adjust the position relationship between the arm base
and main unit according to the operating instructions of
the optional arm base.
4. Insert the mounting screw into the hole of the arm base
and tighten it using the hex wrench securely.
If the screw is not sufficiently tightened, the sound quality
may be adversely affected. Thus tighten the screw securely.
5. Connect the supplied phono cable to the tone arm se-
curely.
6. Secure the phono cable using the supplied phono cable
securing cushion.
Select a cushion whose thickness is best suited for
placement.

How to Assemble
5. Pulley cover mounting
Insert four corners slowly and evenly as shown below.
6. Rubber mat mounting
The face with a hollow in the center is the upper side.
Put the rubber mat on the platter by aligning it with the cen-
ter spindle.
7. Dust cover mounting
The dust cover has a plug-in type hinge.
Insert the hinge attached to the dust cover into the hinge
receiver attached to the rear side of the main unit all the way
in a straight manner.
If the acrylic portion of the dust cover is pushed firmly, the
portion may be cracked. Therefore, insert rather than push
the hinge portions at the right and left sides at the same time.

Before Connecting
Before connecting other devices, connect the jack side of the
accessory power cable to the AC inlet of this unit.
When connecting, turn off the power switch of this unit and
the power supplies of auxiliary devices to prevent unexpected
accidents that may be caused by noise.
How to connect power supply
Use the accessory power cable and insert the AC plug in an
outlet on the wall in the room where the unit will be installed.
Connection to phono equalizer, integrated
amplifier, or others
Connect the pin plug of the phono cable supplied with the
tone arm to the phono terminal of a phono equalizer or an
integrated amplifier.
Connection of grounding conductor
Connect the grounding conductor of the phone cable sup-
plied with the tone arm to the signal ground terminal of a
phono equalizer or an integrated amplifier to be used.
Failure to observe this may induce hum noise on music signals.

5. Lowering the arm lifter allows the tone arm to be
lowered and playback to start.
6. After playback ends, raise the arm lifter, put the tone
arm back on the arm rest, and press the start/stop
switch to stop the platter.
To prevent the stylus tip and records from being damaged,
