High-Pass/Low Notch
The High-Pass/Notch band is switchable be-
tween High-Pass Filter and Notch EQ functions.
By default, this band is set to High-Pass Filter.
High-Pass Filter Attenuates all frequencies below
the Frequency setting at the selected slope while
letting all frequencies above pass through.
Low-Notch EQ Attenuates a narrow band of fre-
quencies centered around the Frequency set-
ting. The width of the attenuated band is deter-
mined by the Q setting.
