In a ''semi-parametric'' equalizer there is no control for the bandwidth (it is preset by the designer) or is only selected between two presets using a switch.{{cn|date=January 2013}} In a ''quasi-parametric'' equalizer, the bandwidth is
hello depending on the gain level. With rising gain, the bandwidth gets wider.{{cn|date=January 2013}}

A [[graphic equalizer]] also implements second-order filter functions in a more user-friendly manner, but with somewhat less flexibility. This equipment is based on a bank of [[Filter bank|filters]] covering the audio spectrum in up to 30 frequency bands. Each second-order filter has a fixed center frequency and [[Q factor|Q]], but an adjustable level. The user can raise or lower each slider in order to visual(contracted; show full)*[http://www.wikirecording.org/EQ WikiRecording's Guide to Equalization]
