Basics of Equalization 3
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:
