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.
High performance reference clock
A MEMS oscillator that is excellent in temperature character-
istics is used as a reference clock for speed correction.
Rotation speed deviation indicator
This indicator lights (green) in accordance with the setting
rotation speed. If the rotation speed is slower than that, the
indicator blinks (green), and if the speed is faster, the indicator
blinks (blue).
33/45/78 rotation supported
The rotation speed of 78 for SP records is supported as well
as the rotation speeds of 33 and 45.
Tone arm
A universal type static balance tone arm whose cartridge is
simply replaceable is supplied as a standard item.
The knife edge technique, developed by Japanese brand,
SAEC* that was established over 40 years ago is used in the
bearing.
* SAEC is trademark of SAEC COMMERCE Co., Ltd.
Heavyweight platter
This unit is a 4.0 kg (39N) heavyweight platter, which is ma-
chined from aluminum metal to improve rotation accuracy.
Approximately 21.9 N·cm2of moment of inertia has been
achieved.
High rigidity chassis
The chassis uses a machined aluminum top panel with 10
mm in thickness and thick metal plate for the exterior.
A metal plate with 2 mm in thickness is used for the bottom
plate on which an insulator is installed to improve vibration
isolation performance.
Large-sized spindle
This is a large-sized stainless steel spindle with 16 mm in
diameter that uses a ball bearing and a polyetheretherketone
(PEEK)-made thrust bearing to support stable rotation.
Rubber mat
This mat uses vibration absorbing rubber to prevent a record
from vibrating.
Floating mount
The power transformer and motor are installed via a vibration
isolating rubber to prevent vibration from being transmitted to
the top panel.
Large-sized insulator
A vibration isolating rubber is used because the rubber ab-
sorbs unnecessary vibration from external devices including
an audio rack and from the chassis and converts such vibra-
tion into heat.
Headshell
Headshell has the LUXMAN logo.
AC inlet
Power-cable-detachable AC inlet.

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 places of the bottom side to adjust the whole horizontal
balance. When the produce is leveled, keep a gap of ap-
proximately one millimeter between the bottom of the main
unit and each insulator, and then, level the product.
Confirm that there is a gap between the bottom and each
insulator after leveling. This gap allows the insulators to be
more effective and reproduced sound quality to improve.
Counterclockwise for up, and clockwise for down.

How to Assemble
7. Tone arm vertical adjustment
Changing the height of the tone arm allows the record sur-
face to be parallelized with the arm pipe.
Move the tone arm vertically after loosening the screw of the
arm base with the tone arm adjustment wrench, and tighten
the screw when the position is at the vertically appropriate
position.
The tone arm is secured only with the screw of the arm
base. When the screw is loosened, be sure to put the tone
arm on the arm rest and support the whole arm with your
hand to prevent the arm from dropping.
8. Arm lifter vertical adjustment
Raise the arm lifter, loosen the arm lifter vertical adjustment
screw with the arm lifter adjustment wrench, and adjust the
arm lifter position so that the gap between the stylus tip
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
Remove the tone arm from the arm rest in the state that the
anti-skating adjustment knob is set to zero to put the arm
into the free state. Move the counter weight frontward or
backward by rotating the weight to finely adjust the horizon-
tal 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.
Then, rotate the gauge in the direction as shown in the il-
lustration below to set it to the required stylus pressure val-
ue. Refer to the instruction manual of your cartridge for the
optimal value. A cartridge with 4 to 10 grams in weight is
suitable for this product. For a heavyweight cartridge, use
the optional heavy weight.
The stylus pressure gauge is not fixed on the counter
weight, and is freely rotatable.
