Only when the audio input is sufficient and the power supply voltage/current input is sufficient, can there be enough power output.
The higher the power supply voltage, the greater the output power;
The smaller the impedance of the speaker, the greater the output power. It is recommended to use a 4Ω speaker.
Finally, please make sure that the power of the adapted power supply is greater than the actual working power of the AMP to ensure the maximum output power
The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug it for a long time, you can unplug the DC plug on the machine. Properly increasing the voltage or reducing the speaker impedance can effectively increase the output power.
