Are you trying to figure out what the HPF (High Pass Filter) button does on your audio mixer? This guide will help you know what it does, when you should use it, and when you should avoid it.
Quick Answer: The HPF (High Pass Filter) Button will roll off the lower frequencies (typically between 80-120Hz and below) to help clean up the sound of your microphone.
A high-pass filter (HPF) is an electronic filter that let’s frequencies pass when they are above the cutoff frequency. Put another way, it reduces frequencies that are lower than the threshold. Typically, high pass filters are set between 80-120Hz.

The HPF is a useful too to clean up unwanted frequencies for a variety of inputs. We recommend using the HPF button on:
