  Prompt:

  Only when the audio input is sufficient and the power supply voltage / current is sufficient, will there 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 adapted power supply is greater than the actual working power of the amplifier!

  Package includes:

  1 x Audio Power Amplifier Board kit
