2 x 50W Bluetooth 5.0 Multipoint Audio Amplifier Board – TSA3118M
TSA3118M can also be connected to our TSA1000 external audio volume control board. People can adjust the audio volume by rotating the real knob.
- TSA3118M can auto-detect the Aux in/Line in Audio input. Therefore, Bluetooth audio source has higher priority. When Bluetooth audio is paused or disconnected, the Amplifier will output the Aux in/Line in audio.
- Multiple TSA3118M boards can be connected to become a multi-channel amplifier system. In addition, the Audio out port can also be connected to a subwoofer amplifier board.
- BVC Port: BVC port can be connected to our Audio volume controller to control the Bluetooth audio volume.
TSA3118M can auto-detect the Aux in/Line in Audio input. Bluetooth Audio source has higher priority. When Bluetooth audio is paused or Bluetooth is disconnected. The Amplifier will output the TV audio.
TSA3118M + TSA1000, Both RCA input and Bluetooth audio volume can be controlled through the BVC port
Multiple boards work together.
How to Use:
- Power up TSA3118M and double-click S1 on the Bluetooth module, and the board goes into pairing mode (Voice: Pairing, LED: Blue LED fast blink).
- Now, your smartphone will be able to find a new Bluetooth device whose name is “TSA3118M”. Connect it.
