Frequency Divider BoardThis module is a subwoofer processing circuit powered by dual power , which is also known as a low-pass filter. The output terminal is connected to a common pure rear stage power amplifier, which can form a subwoofer power amplifier.The input can channel or stereo. It is very flexible and convenient to use,and the circuit consumes very little power. A 5-10W transformer is sufficient.This module is a subwoofer processing circuit powered by dual power , which is also known as a low-pass filter.
