Graphic Equalizer

The graphic equalizer offers 31 standard ISO

center frequency controls with constant Q or

proportional Q filters, as well as adjustable filter

bandwidth.

GEQ Parameters

:

Faders

: Graphic representation of the 31 EQ

filter controls. Adjust faders one at a time, or

drag across any region of the graph to adjust

faders.
To return all GEQ faders to their "0" setting,

click or tap the "Flatten" button in the upper left

corner of the graphic display.

Filter Type

: This selects proportional Q or

constant Q (default) filters.

Constant Q filters have consistent Q/

bandwidth regardless of the amount of

boost or cut.

Proportional Q filters get narrower with

increasing boost/cut.

Differences in filter shapes can be observed on

the frequency response display.

Bandwidth

: This sets the bandwidth of all

GEQ filters to the same value within a range of

1/4 octave to 1/2 octave (before proportional

adjustment). The default bandwidth is 1/3

octave.

High-Pass Filter

A high-pass filter (HPF) is a single ended filter

without a level control, passing only signal

above the selected corner frequency. Filter

types include Bessel, Butterworth, Linkwitz,

and Linkwitz Notch, including a variety of filter

slopes.

HPF Parameters

: filter type, frequency

Low-Pass Filter

A low-pass filter (LPF) is a single ended filter

without a level control, passing only signal

below the selected corner frequency. Filter

types include Bessel, Butterworth, Linkwitz,

and Linkwitz Notch, including a variety of filter

slopes.

LPF Parameters

: filter type, frequency
