Original description

Please pay attention to the positive and negative power supply when using it.
   With negative voltage conversion circuit, the input single DC can be converted into positive and negative dual power supplies, and the voltage is doubled; the minimum input of this board is 5V to work, and the internal working voltage is±5V, the internal voltage when entering 12V is±12V, high voltage is helpful to ensure that the dynamic range is not easy to distort.
   In the front circuit of the karaoke, the power supply voltage is critical. The single 12V power supply board is distorted and broke, so the dual power supply is better.
This circuit design is clever, the wiring is reasonable, and the bottom noise is quite low. The actual audition is no less than the M65831.
The spacing of the microphone socket is 25mm, and the distance between the second microphone to the first potentiometer is also 25mm. The distance between the other potentiometer is 20mm.
