To connect the TPA3116 digital power amplifier board to your audio source, follow these steps:
1. Connect the power input to a DC 12-24V power supply. Make sure the power supply is capable of providing a current of more than 3A. When the power is turned on, the power indicator will light up in red and the blue light will flash.
2. Connect the audio input to your desired audio source, such as an MP3 player, mobile phone, computer, TF card, etc. You can use the Bluet (Bluetooth) input, TF card input, or the AUX 3.5mm audio line input.
3. Connect the audio output of the amplifier board to your speaker. Pay attention to the positive and negative connections.
4. If you are using the Bluetooth or TF card audio input, you can adjust the volume and switch songs by connecting the power cord to the "+ VOL -" three holes on the board. Connecting the "+" and "VOL" holes will increase the volume, while connecting the "-" and "VOL" holes will decrease the volume.
5. It's important to note that the board will automatically select the last audio input used. For example, if you previously used the Bluetooth audio input and then connect the AUX input, the board will automatically switch to the AUX audio input.
