A module with an active low-pass filter based on NE5532 systems. The input and output signals are connected via screw connections. Two potentiometers allow you to smoothly adjust the gain and cut-off frequency in the range from 22 Hz to 210 Hz. Thanks to the filter used, only the low tones (bass) are amplified, which is why the module is dedicated to bass speakers (subwoofer). The board should be connected between the audio input and the power amplifier and requires a symmetrical power supply. It works well in home and car audio systems.
