NOTE

  • 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.
  • 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.
