TSA3118M is a 2x50W Stereo Bluetooth 5 multipoint audio amplifier board. It has perfect class-D architecture(Based on TPA3116D2) and each channel has 50W power output. Both of channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC10V-24V power supply. It can be used to drive any 4Ω or 8Ω passive speakers. TSA3118M can also be connected with our TSA1000 external audio volume control board. People can adjust the audio volume by rotating the real knob.
- TSA3118M can automatically detect the Aux in/Line in Audio input. Bluetooth audio source has a higher priority. When Bluetooth audio is paused or bluetooth is disconnected, the amplifier will output the Aux in/Line in audio.
- Multiple TSA3118M boards can be connected together to become a multi-channel amplifier system. The Audio out port can also be connected with a subwoofer amplifier board.
- BVC Port: BVC port can be connected with our Audio volume controller to control the Bluetooth audio volume.
TSA3118M can automatically detect the Aux in/Line in Audio input. Bluetooth Audio source has a higher priority. When Bluetooth audio is paused or bluetooth is disconnected, the Amplifier will output the TV audio.
