The higher the power supply\nvoltage, the greater the output power; The smaller the impedance of the\nspeaker, the greater the output power. It is recommended to use a 4Ω speaker.\nFinally, please make sure that the power of the adapted power supply is\ngreater than the actual working power of the AMP to ensure the maximum output\npower. Warm Reminder: The power switch on the board is a standby switch. After\nthe switch is turned off, the machine is in a low-power standby state. To\ncompletely turn off the power or unplug it for a long time, you can unplug the\nDC plug on the machine. Properly increasing the voltage or reducing the\nspeaker impedance can effectively increase the output power.
