TEAC TN-4D-SE Direct Drive Turntable with SAEC Tonearm - TEAC

TN-4D-SE: Employing an ultra-stable, direct-drive motor, a classically designed turntable with knife-edge tonearm bearings
The TN-4D-SE 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.

Its 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, high-resolution 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 line-level 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.

To extract the music from your vinyl, the TN-4D-SE 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-SE 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.

A sleek motor, developed exclusively for direct-drive turntables
The TN-4D-SE 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.

Knife-edge, pivot-point tone-arm bearings
In collaboration with SAEC Corporation, a world-famous, high-end tonearm manufacturer, the TN-4D-SE'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.

Pre-installed Oyster cartridge by SUMIKO
The TN-4D-SE 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.

Built-in PHONO EQ amplifier supporting MM cartridges
The TN-4D-SE 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.

Die-cast aluminum platter
In conjunction with the newly-developed motor, the high inertia, die-cast aluminum platter helps to achieve better speed stability.

Insulating feet with excellent shock absorption
The insulating feet comprise a machined aluminum 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-SE is very resistant to acoustic feedback.

2-speed turntable for 33-⅓ and 45 rpm
The TN-4D-SE supports 33-⅓ 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 aluminum.
