The TEAC TN-4D-SE is a precision direct-drive analog turntable featuring a newly developed brushless DC motor with feedback control for highly stable rotation. Its slim design incorporates a knife-edge, pivot-point tonearm bearing system developed in collaboration with SAEC, a die-cast aluminium platter and a factory-installed SUMIKO Oyster MM cartridge. A built-in PHONO EQ amplifier provides convenient connection to both PHONO and LINE inputs.
Unlike a belt-drive design, the TN-4D-SE connects the motor directly to the platter. Its newly developed brushless DC servo motor uses a feedback control system to maintain accurate rotational speed. The low-profile motor also allows TEAC to achieve a slim chassis design while maintaining stable platter rotation.

| Motor | Brushless DC Servo Motor |
| Playback Speeds | 33⅓ RPM / 45 RPM |
| Wow & Flutter | 0.1% or less |
| Signal-to-Noise Ratio | 67 dB or higher |
The 30 cm aluminium die-cast platter provides a rigid, high-inertia platform for stable record playback. Its combination with the direct-drive motor contributes to accurate speed regulation and smooth rotation.

The TN-4D-SE uses an S-shaped static-balanced tonearm incorporating a knife-edge, pivot-point bearing system developed with SAEC. The bearing design allows smooth vertical movement and precise stylus tracking. The universal headshell fitting also makes cartridge and headshell changes straightforward.
| Tonearm Type | S-Shaped, Static-Balanced |
|---|---|
| Effective Length | 223 mm |
| Tracking Force Range | 0–5.0 g |
| Compatible Cartridge Weight | 4.0–13.0 g |
| Compatible Weight Including Headshell | 14–23 g |
| Anti-Skating | Adjustable |
The turntable is supplied with a factory-installed SUMIKO Oyster MM cartridge. The cartridge is mounted on the headshell and is designed to provide straightforward setup and compatibility with the TN-4D-SE's integrated MM PHONO EQ stage.
| Cartridge Type | MM |
|---|---|
| Model | SUMIKO Oyster |
| Output Voltage | 4.0 mV at 1 kHz |
| Tracking Force Range | 1.5–2.5 g |
| Recommended Tracking Force | 2.3 g |
| Cartridge Weight | 5.3 g |
| Replacement Stylus | SUMIKO Oyster Replacement Stylus |
The integrated PHONO EQ amplifier uses an NJM8080 op-amp designed for high-quality audio applications. It raises the low-level cartridge signal to line level, allowing the turntable to connect directly to a standard line-level input. The output can also be used in direct PHONO mode with an external phono stage.
| PHONO EQ | Built-In, MM Compatible |
|---|---|
| Output Selection | PHONO / LINE Switchable |
| PHONO Output | 4.0 mV at 1 kHz |
| LINE Output | 224 mV (-13 dBV) |
| Output Connectors | Gold-Plated RCA |
| Ground Terminal | Yes |
The TN-4D-SE uses a low-profile cabinet with a multi-layer piano-black or natural walnut veneer finish. Its insulating feet combine a machined aluminium shell with a rubber cushion to absorb external vibration and help resist acoustic feedback.
