Basics of Equalization 3
To further illustrate the differences, here is a pair of examples in which three adjacent bands have settings of + 3 dB, -3 dB, and + 3 dB, respectively:
Remember that at lower gain settings, there is an even wider Q for a given frequency band on a Variable Q equalizer. The center frequency band needs to be edited even more drastically in order for any noticeable reduction of frequencies in its range.
The corresponding illustration for the Constant Q equalizer speaks for itself:
We offer this information regarding the differences between Constant Q and Variable Q equalizers not as an attempt to persuade the world to reject Variable Q equalizers out of hand; in some applications either would do the job nicely. But when a greater degree of control over the program material is needed, a Constant Q equalizer like the DEQ830 offers a significant advantage.
