Features of This Unit
Belt drive
This product uses a belt drive system to decrease motor vi-
bration and rotation irregularity and to obtain smooth rotation.
Circuit configuration
Rotation speed can be measured with the hall element of the
motor, and the PID control system is adopted to reach the
setting rotation speed smoothly in a short time.
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.
Arm base
For the arm base, 20-mm brass chrome plated spin finish
is used. Replacement of the the existing arm base with the
optional one allows users to mount various tone arms, which
enables users to enjoy sound change. A dedicated arm base
that enables 12-inch long arm to be mounted on the rear side
of the main unit will be put on sale as an optional item.
High performance reference clock
A MEMS oscillator that is excellent in temperature character-
istics is used as a reference clock for speed correction.
33-1/3/45/78 rotation supported
The rotation speed of 78 for SP records is supported as well
as the rotation speeds of 33-1/3 and 45.
Tone arm
This item is equipped with a universal type static balance tone
arm that was newly and fully designed under joint develop-
ment with SAEC. The knife edge technique that is excellent
in initial sensitivity is used in the bearing. The effective length
is 10 inches because the length allows tracking errors to be
suppressed and suppressing face deflection to be improved.
* SAEC is a brand of Saec Commerce Co., Ltd. that has a
history of over 40 years in the world of analog audio.
Heavyweight platter

and the record surface becomes 5 to 10 millimeters. After
this adjustment, lower the lifter, confirm that the stylus tip
comes into contact with the record surface, and tighten the
arm lifter vertical adjustment screw to secure the arm lifter.
Confirm that a gap exists between the lifter and arm pipe
at the same time the stylus tip comes into contact with the
record surface.
9. Horizontal balance adjustment
After removing the weight for anti-skating adjustment, re-
move the tone arm from the arm rest to make it free. Move
the counter weight frontward or backward by rotating the
weight to finely adjust the horizontal balance of the tone
arm.
The stylus tip of the cartridge is remarkably delicate. Be
extremely careful not to apply excessive force to it.
10. Stylus pressure adjustment
Set the stylus pressure gauge to zero in the state that the
tone arm is horizontally balanced while carefully preventing
the counter weight from moving.

How to Assemble
13. Instructions on how to adjust the
mounting position of the cartridge
using our OVERHANG GAUGE
When installing a cartridge or a headshell, please use the in-
cluded overhang gauge to set the correct alignment. Adjust
the mounting position of the cartridge as follows to minimize
tracking errors.
1) Temporarily secure the cartridge onto the headshell to
be used.
* Tighten the mounting screws gently and temporarily,
so that you can fine-tune the cartridge position later.
Over-tightening will make it impossible to re-adjust the
alignment of the cartridge.
2) Mount the spindle (SPINDLE) hole of the overhang
gauge onto the spindle of the turntable and lay it on the
platter.
3) Rotate the overhang gauge on the turntable so that the
large arrow mark faces the center of the tonearm's rota-
tion axis.
4) Position the tonearm so that it is directly over the center
of the spindle.
5) Re-position the cartridge so that the needle position of
the model to be used and the stylus tip mark printed on
the overhang gauge match. ( PD-191A: 16 mm)
* When adjusting the position of the cartridge, align the
stylus tip with the center of the headshell and move
the cartridge along the headshell screw tracks until the
needle is in the correct position.
6) Be careful not to move the position of the cartridge as
you tighten the screws firmly to secure it in place.
