Bluetooth TWS & aptX

The main feature of this amplifier module is the integration of an AudioB Plus module on it, allowing it to also become a Bluetooth 4.2 receiver. This AudioB Plus module supports aptX and TWS technologies.

The aptX protocol will provide a much more stable Bluetooth transmission and better signal synchronization. An asset for audio use and quality playback.

The TWS mode will allow you to stream an audio signal with 2 TSA9840B amplifiers at the same time. This way, you can enjoy excellent amplification in dual Mono mode.

The TSA9840B can automatically detect signals on the AUX / Line input. Bluetooth has a higher priority. When Bluetooth is disconnected or paused, the amplifier automatically switches to the AUX / Line input.
