TN-400BT
Analog turntable with Bluetooth® Qualcomm® aptX™ transmitter that streams music from LP Records wirelessly
The TN-400BT is an analog turntable that also allows users to listen to LP records wirelessly via Bluetooth® headphones & speakers. A die-cast aluminium platter provides accurate rotational speed while an S-shaped static-balanced aluminum tone-arm provides accurate tracking. The built-in Phono EQ amplifier enables the TN-400BT to be connected to a conventional hi-fi amplifier or a micro hi-fi, while a universal-type headshell allows users to change cartridges with ease.
A built-in Bluetooth® transmitter also lets users listen to LP records wirelessly with high-quality audio (thanks to the the Qualcomm® aptX™ and AAC codecs). A USB output, meanwhile, enables users to digitally archive their records on a PC at 16-bit/48kHz resolution (equivalent to CD quality). For convenience, a quality Japanese-made moving magnet-type cartridge comes pre-installed, so users can quickly start enjoying their records without a lengthy set-up procedure.

Aluminum die-cast platter with 3-speed belt-drive
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 33-1/3, 45 and 78 rpm speeds.
New low-resistance spindle
A precisely-machined stainless steel spindle and durable brass bearing maintain accurate rotational speed, thanks to reduced friction.
New matt and natural walnut veneer finishes
The TN-400BT is available in four matt finishes, as well as a natural walnut veneer finish.
Built-in Phono EQ amplifier
The TN-400BT 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.
USB digital audio output
The TN-400BT also incorporates an A/D Converter that delivers a 16-bit/48kHz resolution digital audio signal via a rear-mounted USB port. This allows records to be digital archived on a PC. Once converted, users can then easily transfer the recordings onto devices such as smartphones and car CD players
S-shaped static-balanced tone-arm
The S-shaped, static-balanced aluminum tone-arm is equipped with a counterweight and anti-skating mechanism that allow an exact setting of balance as well as tracking pressure, ensuring accurate tracking during playback. A tone-arm lifter is also fitted for smooth lowering of the tone-arm onto records.
The tone-arm takes universal-type headshells so users can change cartridges with relative ease. In order to reduce signal losses between the tone-arm and the headshell, gold-plated contact points are employed, to help deliver an uncorrupted audio signal.
Bluetooth® wireless audio streaming with Qualcomm® aptX™ codec
The TN-400BT's Bluetooth® wireless transmission system supports the higher quality Qualcomm® aptX™ and AAC 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 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.
Beautifully detailed
The TN-400BT 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.
MM-type Cartridge from audio-technica
The deck comes with an excellent, all-purpose MM cartridge, employing a lightweight aluminum cantilever, which helps deliver an accurate, highly musical standard of playback.
