With a negative voltage conversion circuit, it can convert the input single DC into a positive and negative dual power supply, and the voltage is doubled.
This board can work with a low input of 5V. At this time, the internal working voltage is +/- 5V. When inputting 12V, the internal voltage is +/- 12V. The high voltage helps to ensure that the dynamic range is not easy to sing loudly.
In the karaoke front-end circuit, the power supply voltage is very important. The board with a single 12V power supply will be distorted if it is louder, so it is better to have dual power supplies.
Ingenious circuit design, reasonable wiring, and low noise floor.
The distance between the microphone socket 1-2 is 25mm, the distance between the second microphone holder and the first potentiometer is also 25mm, and the distance between the remaining potentiometers is 20mm. The microphone holder and the potentiometer have the same height, which is good for opening holes.
