Product Overview:

This tuning board is a passive tuning board, mainly used to adjust the high and low volume of the input audio signal, and then send it to the amplifier board for amplification. The principle of the product is to directly filter out the desired high and low frequencies through resistive and capacitive components. The tone board does not require power supply, but the volume will decrease significantly after processing.
