# It boosts mid-range frequencies where the detail of footsteps is present, and slightly attenuates very low and very high frequencies.

Preamp: -3 dB

# Low frequencies: Slight reduction to decrease rumble and focus more on footsteps.
Filter: ON PK Fc 150 Hz Gain -2 dB Q 1.4

Filter: ON PK Fc 300 Hz Gain -1.5 dB Q 1.4

# Mid frequencies: Boosting to emphasize the sound of footsteps.
Filter: ON PK Fc 1000 Hz Gain 3 dB Q 1.2
Filter: ON PK Fc 1500 Hz Gain 2 dB Q 1.2

# Upper mid frequencies: These are important for the detail of footsteps.
Filter: ON PK Fc 2000 Hz Gain 4 dB Q 1.2
Filter: ON PK Fc 2500 Hz Gain 3 dB Q 1.2

Filter: ON PK Fc 3500 Hz Gain 2 dB Q 1.4
Filter: ON PK Fc 4000 Hz Gain 1.5 dB Q 1.4

Filter: ON PK Fc 6000 Hz Gain -2 dB Q 1.4
Filter: ON PK Fc 7000 Hz Gain -2.5 dB Q 1.4
