Although Christian already explained it well let me add some words:
Music uses a frequency bandwidth. This can range i.e. from 1 Hz to 48kHz. You can devide this bandwidth from 1 to 48.000Hz into three different parts and you get a low level, mid level und high level bandwidth (comparable to your eq at the build in mixer). So with your low level filter you can filter a part of the frequency bandwidth and if it says 20Hz it means that it filters everything under 20Hz.
