This mixer board is a passive mixer board, whose main function is to adjust the input audio signal for high and low pitch, and then send it to the power amplifier board for amplification.
The principle of the product is to filter the audio signal directly through the resistor and capacitance element to get the desired high and low pitch. The tone board does not need power supply, but the volume will be much smaller
