A die-cast, high-inertia aluminum platter is driven by a high-torque DC motor via a durable rubber flat-belt, giving immensely stable playback at 33-⅓, 45 and 78 rpm speeds.

The TN-400BT-X has an onboard Phono EQ amplifier that supports MM-type cartridges, allowing the deck to be connected to conventional amplifiers/micro systems that lack a dedicated turntable input. The Phono EQ amplifier employs a hi-fi quality NJM8080 op-amp chip (designed by JRC) which amplifies the tiny audio signal from the stylus with the minimum of distortion.

The TN-400BT-X's Bluetooth® wireless transmission system supports the higher quality Qualcomm® aptX™ Adaptive codecs, as well as the conventional SBC codec. This means that even if users don't have a hi-fi system, then can still enjoy truly high-quality vinyl replay via Bluetooth®-equipped headphones or speakers. Connecting the TN-400BT-X to Bluetooth® headphones or speakers is achieved very simply, at the touch of a button. A single-function pairing key and an associated LED indicator provide simple and clear confirmation of the connection status.

The TN-400BT-X brings elegance to the process of playing a record. The machined aluminum operation knobs ooze quality while the aluminum feet, attached to high-density MDF chassis via shock-absorbing rubber, provide a high resistance to feedback.
