HIGH PASS FILTER (HPF) SETTINGS:
A high-pass filter is a special type of EQ that lets the
high-frequencies pass through your mix unaffected,
but filters away the low frequencies. A high-pass filter
can is a very useful feature in a monitor mixer, for
different scenarios:
• Makes your personal mix sound more clear and
intelligible, because it generally reduces the low-
end rumble that can make things hard to hear.
• Some examples of monitoring equipment that
may benefit would include in-ear monitors or
headphones that have too high a bass-response,
inexpensive stage monitors that may have
muffled sounding audio, or any connected stage monitor that uses a smaller diameter speaker
that struggles and distorts when attempting to play very low frequencies.
By only sending the stage monitor or headphones the frequencies they can handle well, and
filtering out the lower frequencies that are below their advertised frequency response, your monitors
can work more efficiently, and not strain trying to reproduce frequencies they are not meant to
reproduce.
You may also find that applying a 80Hz to 120Hz High Pass Filter to floor monitors with help clean up
your master audience mix.
PRESS one of the four HPF frequency choices on the screen to select the specific HPF frequency that
sounds best to you. Choices include:
1. OFF: No High-Pass filter is applied and your mix will pass through the full frequency range.
2. 40Hz: Only the very lowest frequencies, 40Hz or lower, will be filtered out
3. 80Hz: A larger amount of lower frequencies, 80Hz or lower, will be filtered out
4. 120Hz: The largest amount of lowest frequencies, everything from 120Hz or lower, will be
filtered out
