(contracted; show full)tion of the center frequency (in [[Hertz|Hz]]), adjustment of the [[Q factor|Q]] which determines the sharpness of the [[Bandwidth (signal processing)|bandwidth]], and the level or gain control which determines how much those frequencies are boosted or cut relative to frequencies much above or below the center frequency selected. 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}} In a ''quasi-parametric'' equalizer, the bandwidth is depending on the gain level. With rising gain, the bandwidth gets wider.{{cn}}

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 visually approximate a "graph" of the intended frequency response.
