Note:
1.Please allow 0‑2 cm error due to manual measurement. Thanks for your understanding.
2.Only when the audio input is enough and the power supply voltage/current is enough, there will be enough output power.
3.The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power.
4.Please make sure that the power of the adapter power supply is greater than the actual working power of the amplifier.
