Filter Controls

AND ON/OFF

Turns the band on or off.

FILTER TYPE

Selects the filter type for the band. Use the drop-down menu to choose a type, or click on the type button to toggle

through the choices.

Range: Bell (all bands); Lo-Shelf (bands 1 and 2); Low-Rshelf (bands 1 and 2); Hi-Pass (band 1); Hi-Rshelf (bands 3

and 4); Hi Res shelf (bands 3 and 4); Lo-Pass (band 4)

GAIN

Sets the amount of boost or cut introduced to a band bell or shelf filter. For bell filters, gain corresponds with center

frequency. In shelf filters, gain defines the overall boost and the gain at the shelf’s cutoff frequency is in the middle

of the shelf slope. When the selected type is Pass/Cut filter, the gain has no significance.

Range: +/- 18 dB, Default: 0

FREQUENCY

Determines the frequency reference for the band. With a bell filter, the frequency is the center of the bell. When the

filter type is shelf, the frequency is the middle of the shelf slope. When the type is Pass/Cut filter, the frequency is the

-3 dB point of the roll off.

Range (same for all bands): 16 Hz to 21,357 Hz

Defaults: Band 1, 60 Hz; Band 2, 250 Hz; Band 3, 1325 Hz; Band 4, 8000 Hz

Q is the ratio of center frequency to bandwidth. Bandwidth is inversely proportional to Q so that as you raise the Q,

you narrow the bandwidth. Q behaves differently, depending on the filter type: bells are narrower, cut and shelf filters

are more sharply sloped. Additionally, it controls the “bump” in the slope.

• Bell Q corresponds to the width of the frequency range for that band.

• Shelf Q controls the slope of the “side” of the shelf and the resonant dips and peaks.

• Cut (bands 1 and 4 only), Q controls the slope of the cut filter from about 10 dB/oct to 18 dB/oct.
