for the

Constant Q Graphic Equalizers

Crate Pro Audio’s Live Sound Graphic Equalizers feature constant Q circuits which, unlike inferior broad band EQs, let

you boost or cut only the frequencies you choose. Combined with a switchable equalization range, these EQs allow greater
system control and accuracy whether using them for house coloration, feedback control, or speaker correction.

In order to achieve the highest level of performance from your equalizer, please read this owners guide prior to its use.
