Many beginning and novice sound engineers see this little button on their mixing console and never really figure out what it does. This button is usually located just above or below the gain knob on an analog console and may be found in the EQ section of most digital consoles. So what button am I talking about and why should you care?
This is the High-Pass Filter and it is one of the console's most underused buttons.
What is a high-pass filter?
A high-pass filter is an audio frequency filter that cuts out frequencies that fall below a specific frequency level. These filters may be marked as /80 or /100 which simply mean that the filter will cut out those frequencies below 80Hz or 100Hz.
