Cannot use 24V battery, fully charged will cause overvoltage. DC power supply is required, AC power is not supported!!! If using a DC/DC boost module, it is recommended to adjust it to 80% of the limit voltage to avoid module damage caused by overshoot or ripple overvoltage!!!Maximum power: Left and right channels ≤ 75W, subwoofer ≤ 145WCompatible speaker: Left and right channels: 20-75W, 4-8 Ω subwoofer: 50-150W, 2-8 ΩBluetooth distance: transmission distance of 15 metersInput method: Bluetooth+AUX+PC+USB, Bluetooth priority, Bluetooth needs to be disconnected when using audio cable inputNumber of channels: 2.2, left and right channels+dual subwooferProtection mechanism: Input undervoltage, overheating, overcurrent, short circuit protection, with input anti reverse protectionProduct size: Integrated potentiometer 117x116mm, external potentiometer 117x101mmTip: Only when there is sufficient audio input and sufficient power supply voltage/current, will there be sufficient output power!!! The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power!!! Please ensure that the power of the adapted power supply is greater than the actual working power of the amplifier!!!Product List:1X power amplifier board1X screwdriver
