The TinySine TSA9840B is a small Class D amplifier module, based on a MAX98400A amplifier chip, allowing to deliver, in this mono version, a power of 20W. This module can then be used to power a passive speaker 8Ω. For more convenient use, the TSA9840B can be associated with volume controllers TSA1000 and TSA1020.

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.

The TSA9840B and TSA1000 modules can be associated via the BVC port, allowing you to control the volume level on the AUX and Bluetooth inputs.
