An active crossover filter that allows you to convert your typical stereo audio system into a 2.1 system meaning you can add a subwoofer to your speakers to improve your sound without replacing anything from your current audio setup.
I made it because I needed a cheap and simple solution to improve my room audio without having to buy large filter PCBs with large double-voltage power supplies.
This new updated design filter PCB features :
Standard 1/8 (3.5mm) inch audio jacks for stereo input, high-pass stereo out, low-pass mono out.
Standard USB-C input for power supply (requires at least 100mA at 5V).
Easy 20Hz - 250Hz frequency adjustment with potentiometer using a screwdriver.
Input signal clipping indicating LED lets you know when the signal reaches -1dB.
Tiny size of 1.7" x 1.2" x 0.5" (43mm x 29mm x 12mm).
Each PCB is individually tested and works out of the box.
