- 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 select the Aux in/Line in.
- There is an extra LINE OUT audio output jack. It can also be connected to a subwoofer amplifier board.
- BVC Port: BVC port can be connected with our Audio volume controller to control the Bluetooth audio volume.
