J7 DC Jack ID 2.1mm x OD 5.5mm Inner Outer Power Supply Range: DC12V-24V MODE The OEM-05146 can be cascaded with another OEM-05146 amplifier board. The recommended maximum cascading number of boards is 3pcs on account of audio performance. Therefore, it supports master mode and slave mode, which is recognized by the inserting of the 3.5mm line input cable. Master Mode (The 3.5mm line input cable not inserted) When in master mode, Bluetooth is used as the audio input method to receive audio from connected device. Slave Mode (The 3.5mm line input cable inserted) Once the 3.5mm line input cable is inserted (J3), the Bluetooth will be disabled and the amplifier board will enter into slave mode and receiving audio signal from the OEM-05146 in master mode. INPUT Bluetooth Input The Bluetooth connectivity range is 10m with the antenna. It is suggested to connect the antenna for stable connection and longer range.
