Luxus Audio - BTBU42AJ

BTBU42AJ is a powerful and compact Bluetooth audio receiver. This Bluetooth music receiver connects to the Line-In or Aux input of the home audio system. You can then transmit the audio from your mobile phone or Bluetooth enabled mp3 player to your home audio system. Enjoy the convenience of having your music source in the palm of your hand and listening to it through your home stereo.

We have enabled the TWS function on this tab. The user can also use two of this card to build a wireless stereo speaker system. The default setting of the receiver card in TWS mode is the mono-channel output. People can transmit audio to two separate Bluetooth speakers, from the left channel to the left speaker and from the right channel to the right without connecting them with wires. You can also set it to provide two separate stereo channels (need a programmer and a cable kit).

Note: BTBU42AJ can automatically detect the Aux / Line input in the audio input. The Bluetooth audio source has a higher priority. When Bluetooth audio is paused or bluetooth disconnected. BTBU42AJ will output the Aux in / Line audio.
