Protection mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protection. Note: When the audio signal input is large enough and the power supply voltage/current is large enough, there will be enough output power! The higher the power supply voltage, the greater the output power, the smaller the horn impedance, and the greater the output power! Please ensure that the power of the adaptive power supply is greater than the actual working power of the power amplifier!
