The AudioControl ACX-BT1 is the ultimate solution for giving your audio system Bluetooth connectivity. The ACX-BT1 features the latest Bluetooth 4.1 and aptX HD support, delivering 24-bit clarity, lower noise, faster initial connection and more reliable streaming from a greater distance. The ACX-BT1 is IPX5 rated for marine and motorsports applications, so it will withstand the rigors of all-weather conditions, including as a standalone (no head unit) solution common to side-by-sides, jet skis and more. Installers will appreciate the unique remote turn-on output circuit that triggers downstream amplifier(s) only when audio is being played over the Bluetooth connection.
