How-to: Use the Parametric EQ

Parametric EQ, our professional and clean sounding 8 band equalizer. A high quality EQ is one of the most important tools in your effects arsenal. Parametric EQ enables you to sculpt your sound with three different band types: Low/High Pass filters, Peak filters and Low/High Shelving filters. Easily adjust the frequency of all available bands and use the 4 analyzer modes to view the frequency spectrum.

1) The equalizer band points

Adjusting band points

Each equalizer band has its own color coded point. Click and drag the points to easily set the frequency position and gain value. Hold down shift while clicking and move the mouse left or right to adjust the Q-value. You can also change the Q value with mouse scrolling. Double click a band point to reset it to its default value.

2) The equalizer bands and master gain

Here you can change and see the exact values of each band. You can also activate or bypass each band individually by clicking the band icons. A darker color indicates the band is bypassed.

Frequency value

Each band allow you to set the frequency position in the top row by clicking and dragging the number. You can also click once to type in exact frequency values.

Gain and Slope values

The middle row allow you to set the gain value of the band, which is by how much you boost or cut the frequency of the band. Click once to type in your desired value or click and drag up/down to adjust.
The High and Low Pass bands have a "slope" value instead of a gain. The slope is adjustable between 6, 12, 18 and 24 db per Octave. This means by how much or "fast" the frequency drops in level. A low value is a slower drop while a high value is a faster one.

Q value

The bottom row is the Q value and controls the width of the band or simply put how many frequencies will be affected by the band. A low Q value will give you a wide band and affect more frequencies. A high Q value will give you a more narrow band and is great to cut or boost more specific frequencies.
For Low/High Pass filters and Shelving filters a high Q value will add a more defined "bump" at the frequency position resulting in a small boost or a more resonant sound with extreme values.

The Bands

Band 1: High Pass filter
Band 2: Low Shelf filter
Band 3-6: Peak filters
Band 7: High Shelf filter
Band 8: Low Pass filter
Master: This isn't an actual "band" but is where you can change the overall output volume of the Parametric EQ. You can boost or lower the volume by 20 dB.

3) The Analyzer view

Four analyzer modes

The Analyzer drop down menu allow you to select and view the frequency spectrum in four different ways and is shown behind the EQ band points. The four modes are Spectrum, Polygon, Bars and Colors. Colors is the most different of the mode and show the density or loudness of frequencies in terms of color intensity. The brighter the color the more or louder the frequency in that area.

Frequency ranges

The display of the EQ let you see the frequency ranges in three ways.
At the top of the display you can quickly see the ranges in terms of Low Bass, Bass up to PRS (presence) and Treble.
The middle line of the display give you frequencies in Hz, from 20 Hz up to 20 kHz.
The bottom of the display is a musical range from octave C1 to C9. Here you can quickly see the musical octave of frequencies.
