Three input methods!（USB、AUX、Bluetooth).When these three input methods input audio signals at the same time, their priority order is USB→AUX→Bluetooth. In other words, if you want to use AUX, you need to disconnect the USB input audio; if you want to use the Bluetooth mode, you need to disconnect both the USB connection and the AUX connection. Warm reminder: The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug it for a long time, you can unplug the DC plug on the machine. Properly increasing the voltage or reducing the speaker impedance can effectively increase the output power.
