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.
Equalisation circuit similar to a Sweep eq, but with the addition of an extra control to specify how wide the choosen frequency band will be......That is, suppose you select a sweep eq tuned to 1KHZ......When you cut or boost the choosen band (1K) it will also effect frequencies adjacent either side of the choosen 1K band, but with a sliding scale......So perhaps the circuit cut & boost will effect signals down from 1K to about 800 HZ, and up from 1K to about 3K, but the further away from the center frequency, the less the frequencies are cut or boosted. The additional control on a Parametric eq is known as the "Q"......This control adjusts how wide a band of frequencies will be, either side of the choosen level. By adjusting the Q on a Parametric to be very tight, you can tune in very tight to a buzz or hum, or an irritating frequency, and cut it out.....Or tune into a sweet spot, and boost it.
An EQ in which the frequency and bandwidth are fully adjustable.
A graphic equaliser in which the cut/boost, frequency and bandwidth are all adjustable.
a sweepable EQ that also gives you the ability to adjust the bandwidth
An equalizer with adjustable frequency, level, and "Q"
parametric EQ lets you control the basic characteristics of the equalization filter. Generally, you can control the amount of cut or boost, the center frequency, and (mostly on studio mixing boards), the Q or width of the frequency range affected by the EQ. A parametric EQ lets you focus the effect of the tone control right where you need it - to increase the punch of slapped strings, or reduce the low midrange to clean up guitar chords.
Parametric equalization or tone controls allow you to set not only the amount in dB by which a certain frequency band is boost or cut, but also the width and/or center frequency of this band. This gives you extremely precise control of the tonal balance in your vehicle. Parametric equalizers are more versatile than graphic equalizers, which have fixed center frequencies and bandwidths.
Final Cut Pro has a parametric EQ in the Apple plug-ins folder. Parametric EQs work differently than graphic EQs in that with a graphic EQ, you adjust each of the bandwidths you want to effect separately. With a parametric EQ, you set a center frequency and all of the surrounding frequencies are also adjusted in various curves and patterns around the center frequency.
An equalizer in which all of the parameters of equalization can be adjusted to any amount including: a) center frequency; b) the amount of boost or cut in gain; and c) the bandwidth. - Category: Manufacture of Gear
