1 Band EQ
The 1 Band EQ may be set to any one of six EQ
types: High-Pass, Notch, High-Shelf, Low-Shelf,
Peak, and Low-Pass, by clicking the correspond-
ing icon in the EQ Type selector.
Band Controls
The individual EQ types have some combina-
tion of the following controls, as noted below.
EQ Types
High-Pass Filter
The High-Pass filter attenuates all frequencies
below the Frequency setting at the selected rate
(6 dB, 12 dB, 18 dB, or 24 dB per octave) while
letting all frequencies above pass through. No
gain control is available for this filter type.
Notch Filter
The Notch Filter attenuates a narrow band of
frequencies centered around the Frequency set-
ting. No gain control is available for this EQ
type. The width of the attenuated band is deter-
mined by the Q setting.
