Class D Amplifier Module 2x20W MAX98400A Bluetooth aptX TWS
The TinySine TSA9840B is a small Class D amplifier module, based on a MAX98400A amplifier chip, delivering 2x20W power. This module can then be used to power two 8Ω passive speakers. For a more practical use, the TSA9840B can be associated with volume controllers TSA1000 and TSA1020.
The TSA9840B can automatically detect audio input. Bluetooth has a higher priority. When Bluetooth is disconnected or paused, the amplifier switches directly to the Line in.

The main feature of this amplifier module is the integration of an AudioB Plus module, allowing it to also become a Bluetooth 4.2 receiver. This AudioB Plus module supports aptX and TWS technology.
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 to 2 TSA9840B amplifiers at the same time. So you can enjoy excellent amplification in Dual Mono mode.
To pair your Bluetooth device with the TSA9840B, enable Bluetooth on your transmitting device. After a search, the module "TSA9840B" should appear in the list. Just choose it to start streaming.
