The TN-400BT is an analog turntable that also allows users to listen to LP records wirelessly via Bluetooth® headphones and 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.
