    Features:

    • Size: 9.1cm x 5.0cm
    • Bluetooth 4.0
    • Bluetooth audio volume control port(BVC)
    • Working voltage: DC10V-24V
    • Thermal and output current protection
    • 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.
