- TSA9840 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 Aux in/Line in audio.
- There have an extra LINE OUT audio output jack. It 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.
