Protection mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protection
hint: When the audio input is enough and the power supply voltage/current is enough, there will be enough output power The higher the power supply voltage, the greater the output power, the smaller the speaker impedance, the greater the output power Please make sure that the power of the adapter power is greater than the actual working power of the amplifier
