with
the same basic quality as the beet selling turntable, the
PDT-5000.
l FAST STARTS BY HIGH TORQUE
Using high-torque
direct motor, the in&Dal motor’
delivers l&g-cm
start torque. The high-torque gives
quick starts that enables the platter to reach 33-H rpm
within 0.5 second.
l FLOATING SUSPENSION TONEARM
The tonearm is mounted on the deck plate using a
floating
suspension
system
with the drive moter.
Acoustic feedback is minimised by this advanced system.
l QUARTZ-PHASE-LOCKED
CONTROL
The pitch is variable continuously by up to approximately
f 10% and returned automatically
to the predertermined
speed (38-x or 45 rpm) by on/off switch even if the
pitch control is employed.

Adjustment of Overhang
Use a rule, etc. to carry out correct adjustment,
As shown in the illustration,
overhang indicates the
distance from the stylue tip to the center of the
turntable spindle when the stylus tip falls on the
extension of e straight line from the pivot of the
tonearm to the center of the spindle. If the overhang
adjustment ls not properly made, the stylus will not
be able to trace the record grooves correctly.
1. Loosen the two cartridge mounting screws.
2. Position the tonearm over the spindle.
3. Slide, the cartridge forward or backward until the
position of the stylus tip corresponds to the
specified distance from the center of spindle (see
illustration).
4. After, obtaining correct overhang, tighten the two
cartrIdge mounting 8~2-9~~ firmly.
Note : Be shure not to touch stylus during adjustment
with finger.
Adjustment of Horizontal Zero Balance
1. Release the tonearm from the armrest to free.
Note 1Be careful not to touch your hger to the
stylus tip.
2. Turn the balance weight clockwise or counter
clockwise until the tone arm is balanced
horizontally.
3. (see fig. 4)
aExcessive backward retreatment of the
balance weight causes the cartridge side

b-The balance weight and cartridge are
balanced, the tonearm is held horizontal.
c.Excessive forward advancement of the
balance weight causes the cartridge side

1. Hold the balance weight with one hand as shown in
the drawing (see fig. 5 1, and rotate only counter
ring to bring the numeral “0” of the ring into
alignment with the center line an the tonearm tear
shaft (see fig. 5).
Note : In case the balance weight moved, do the
adjustment of holiaontal zero balance again.

QUARTZ LOCKED CONTROL AND PITCH ADJUSTMENT
1. Whan the indicator
lamp is lit ehowing the
uporating condition tar the pi-e-determined spec.d
(33-H Or 45 rpm).
Z.During the operation of m-e-determined speed, pitch
control fader can not be functioned. And once press
the quarts control button, the indicator lamp is put
out, the speed can be adjusted by pitch control
fader.
3. During the operation of above 2., if you want to
change the speed to the pre-determined
one, press
the quartz butlon. The indicator lamp lights and
speed will become pre-dotermined
one even when
the pitch control fader not in the center.
4.Pitch control is poseiblo up to a maximum
of
approximately
rtlO%. Adjust the Pitch by sliding
the Pitch Control Fader.
ACOUSTtC FEEOEACK AND HUM
Acoustic Feedback is uaally caused by vibration of
speakers, which affects the ecnsitive cartridge. If such
a phenomenon
occurs, relocate the turntable
or
speakers as far apart from each other as possible.
Hum ie usually caused by nearby appliances that use
transformar
or thermostat.
Relocating
the unit
further away from the noise sources will readily
solve the problem. Hum may also be produced if the
unit is not properly
grounded.
Make sure the
grounding wire extending from the unit is securely
connected to the GND terminal on the amplifier or
mixer.
-Ii-
Do not place the unit where it is exposed to direct sun
bght, high temperature
or humidity
to prevent
pesslble troubles.
Place the unit in a stable and holizontal position,
where there is little or no vibration.
Locate the unit as far away from the speakers as
possible and isolate the unit’ from sound radiation
from them.
rf the unit is placed too close to the radio,
xnterference to AM/FM reception may result.
