Type selectors The HPF, LPF, LF, and HF band sections have type selectors that toggle between the two
available filter types for that section, as follows:
• High-Pass Filter (HPF band) — Attenuates all frequencies below the Frequency setting
at the selected slope while letting all frequencies above pass through.
• Low-Notch EQ (HPF band) — Attenuates a narrow band of frequencies centered around
the Frequency setting. The Q setting determines the width of the attenuated band.
• Low-Pass Filter (LPF band) — Attenuates all frequencies above the Frequency setting at
the selected slope while letting all frequencies below pass through.
• High-Notch EQ (LPF band) — Attenuates a narrow band of frequencies centered around
the Frequency setting. The Q setting determines the width of the attenuated band.
• Low-Shelf EQ (LF band) — Boosts or cuts frequencies at and below the Frequency
setting. The amount of boost or cut is determined by the Gain setting. The Q setting
determines the shape of the shelving curve.
• Low Peak EQ (LF band) — Boosts or cuts a band of frequencies centered around the
Frequency setting. The Q setting determines the width of the selected band.
• High-Shelf EQ (LF band) — 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 shelving curve.
• High Peak EQ (LF band) — Boosts or cuts a band of frequencies centered around the
Frequency setting. The Q setting determines the width of the selected band.
Q (Peak and Notch bands) Controls the width of the EQ band. Higher values represent
narrower bandwidths. Lower values represent wider bandwidths.
(Shelf bands) Changes the Q of the shelving filter. Higher Q values represent steeper
shelving curves. Lower Q values represent broader shelving curves.
(High-Pass and Low-Pass bands) Lets you select from any of the following Slope values: 6
dB, 12 dB, 18 dB, or 24 db per octave.
Freq Lets you set the center frequency (Peak, Shelf, and Notch EQs) or the cutoff frequency
(High-Pass and Low-Pass filters).
Gain Lets you control the amount that the selected frequencies are cut or boosted (for Shelf and
Peak only).
Frequency Graph
Display
Shows a color-coded control dot that corresponds to the color of the Gain control for each
band, and a frequency response curve. You can adjust the parameters by dragging one or
more of the control dots.
