- MUTE: Connect MUTE pin with GND pin. The amplifier board will into mute state.
- STBY: Connect STBY pin with GND pin. The amplifier board will into standby state to save the power.
- B/A: Connect B/A pin with GND pin. The bluetooth input will always be the audio source no matter the audio source selecting switch position.
Note: We had tested it. It also works well with 12VDC power. But we suggest use DC14V-39V power if possible.
