How many signal input methods does it have? Bluetooth & AUX ! When these two input methods input signals at the same time, the Bluetooth input method is the priority input method. If you want to use AUX, please disconnect the Bluetooth connection. Is it durable? This is beyond doubt! This amp board has 4 kinds of protection mechanisms: overvoltage protection, undervoltage protection, overheat protection, short circuit protection, which means it is not easy to be damaged! 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.
