3 Basics of Equalization

In the next illustration, the difference between a narrow Q and a

wide Q is seen:

Variable Q

Now we're ready for a visual definition of the term Variable Q. In

the next illustration, the wider and more gradual curve represents a

lower gain setting for a variable Q equalizer. The narrower and

more steep curve represents a higher gain setting at the same

frequency:

The previous illustration has been exaggerated somewhat to make

the point, but you can see how a lower gain setting also boosts

frequencies that overlap to some extent into the regions affected

by the next highest and lowest frequency band controls.

Constant Q

In contrast, a Constant Q equalizer has a more consistent range of

frequencies under its control throughout its cut/boost range, as

illustrated below:

1 2 ... 49 50 51 52 53 54 55 56 57 58 59 ... 79 80
