Modern EQ HPF On / Off and Frequency
High-pass filters are utilized to cut out low frequencies. The high-pass filter control adjusts the cut-off
frequency for the filter. Frequencies below the cut-off frequency are attenuated at a rate of 12 dB/octave.
The slope for the HPF is adjustable by sliding the HPF ball or HPF slider left and right. Simply tap the HPF
button – near the lower-left corner of the screen – to engage the high-pass filter. It will illuminate green
when engaged and is gray when disengaged.
