Band Controls
The individual EQ types have some combination
of the following controls, as noted below.
1 Band EQ III 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.

The High Shelf EQ boosts or cuts frequencies at
and above the Frequency setting. The amount of
boost or cut is determined by the Gain setting.
The Q setting determines the shape of the shelv-
ing curve.
