Product overview
The TN-4D is a direct-drive, analog turntable with an elegant, low-profile design, made possible by
the use of a newly-developed brushless DC servo motor.
Our new brushless DC motor (with feedback control system) achieves crystal-locked speed stability
and smoother rotation while also eliminating cogging*. This low-profile motor allowed us to design a
plinth that’s extraordinarily sleek and stylish compared to that of most other direct drive turntables.
The new tonearm employs knife-edge, pivot-point bearings, developed in collaboration with SAEC
Corporation, a world-famous, high-end tonearm manufacturer. The result is an insightful, highresolution sound quality that tonearms with conventional bearings can’t match. Partnering it is a
carefully designed PHONO EQ amplifier that allows you to directly connect the turntable to the linelevel inputs of your existing hi-fi system. A high quality NJM8080 op-amp, specially designed for hi-fi
applications by New Japan Radio Corporation, is employed to convey the finest of musical detail.
Additionally, a USB port on the back panel allows you to digitally archive your vinyl collection via your
PC/Mac.
To extract the music from your vinyl, the TN-4D comes with a highly-regarded Oyster MM cartridge
from SUMIKO – a legendary American cartridge manufacturer. Noted for its innate musicality, the
cartridge comes pre-installed on the headshell at the factory, allowing near ‘plug and play’ operation.
The S-shaped tonearm meanwhile allows for quick cartridge/headshell swaps, so users can alter the
sound quality by experimenting with different cartridges, if the desire takes them.
The TN-4D is an analog turntable that achieves highly accurate rotational speeds and is very
distinctive, for a direct-drive design, thanks to its sleek and stylish aesthetics.
What is Cogging?
Cogging is a phenomenon in which the periodic attraction of the armature and rotor inside the motor is
dependent on the rotation angle, resulting in a fine pulsing. For example, if you turn the axle of a motor with
your fingers, you'll feel the rotation occurring in steps. This phenomenon is known as cogging.
In order to eliminate cogging on a direct-drive turntable, a motor needs to have large numbers of poles, along
with complex circuits and a mechanism to achieve smooth rotation. As a result, most turntable direct-drive units
are relatively large, which is why the resulting turntables are so bulky.
New motor, developed exclusively for direct-drive turntables
The TN-4D uses a sleek, brushless DC motor, offering crystal-locked speed accuracy, regulated by a
computer-controlled feedback circuit and achieving low wow-and-flutter levels for a direct drive
turntable, especially one with such a stylish, low-profile design.
Die-cast aluminium platter
In conjunction with the newly-developed motor, the high inertia, diecast aluminium platter helps to achieve better speed stability.

Knife-edge, pivot-point tonearm bearings
In collaboration with SAEC Corporation, a world-famous, highend tonearm manufacturer, the TN-4D's tonearm employs a
knife-edge, pivot-point bearing. Unlike the case for tonearms
with conventional bearings, any fine vertical movements
encountered by this tonearm actually help in delivering a more
dynamic sound with excellent resolution. The S-shaped
tonearm also employs a universal headshell fitting, allowing
users to quickly and easily swap cartridges/headshells, and
supports a wide range of cartridge weights (from 14 - 23g / 0.5 - 0.8 oz.)
Precision anti-skating and stylus-pressure adjustment
As you might expect, the tonearm is equipped with a counterweight, for precise stylus-pressure
adjustment, and an anti-skating mechanism.
Built-in PHONO EQ amplifier supporting MM cartridges
The TN-4D comes with a built-in PHONO EQ amplifier that allows you to directly connect the turntable
to the line-level inputs of your existing hi-fi system. The NJM8080 IC from New Japan Radio
Corporation is employed for op-amp duties, bringing up the level of the tiny signals received via the
cartridge up to LINE level strength without any loss of quality.
USB digital output
A USB port on the back panel delivers CD-quality digital audio to your PC/Mac, allowing you to
record/archive your vinyl in a high quality, digital audio format. Once you have archived your vinyl to
digital, it’s a simple matter to listen to them while out and about, via a smartphone/portable audio
player, or in your car (by burning them onto a CD-R or transferring them to a memory card/stick).
And to ensure pristine signal transfer, gold-plated PHONO/LINE output terminals are employed to
prevent analog audio signals from losing quality as a result of oxidation.
2-speed turntable for 33-1/3 and 45 rpm
The TN-4D supports 33-1/3 and 45 rpm for LP and EP records. Our insistence on quality engineering
can even be seen in the construction of the rotary control for start-up/speed selection, formed of
machined aluminium.
Insulating feet with excellent shock absorption
The insulating feet comprise a machined aluminium shell topped with a rubber cushion that is fixed to
the high-density MDF plinth. Thanks to their excellent shock absorption characteristics the TN-4D is
very resistant to acoustic feedback.
Pre-installed Oyster cartridge by SUMIKO
The TN-4D comes with a well-regarded Oyster MM cartridge from
SUMIKO – a legendary American cartridge manufacturer. Regardless of
the type of music, the Oyster cartridge delivers a powerful but insightful
performance.
