Definitions for "PARAMETRIC EQ"
Keywords:  boost, eqs, bandwidth, tune, frequency
Equalisation control where the range of frequencies to be boosted or cut can be selected. Allows the "fine-tuning" of the equalisation.
A "fully" parametric EQ is an extremely powerful equalizer that allows smooth, continuous control of each of the three primary EQ parameters (frequency, gain, and bandwidth) in each section independently. "Semi" parametric EQs allow control of fewer parameters, usually frequency and gain (i.e., they have a fixed bandwidth, but variable center frequency and gain).
An equalizer with multiple rotary controls for center frequency selection, boost and cut, gain and bandwidth adjustment.
