Many mixing consoles have a parametric equalizer on each channel.

Such filters are often included with graphic and parametric equalizers to give full control of the frequency range.

Their first successful product came in 1976, when they developed the SC-66 stereo parametric equalizer.

Parametric equalizers first became popular in the 1970s and have remained the program equalizer of choice for many engineers since then.

A parametric equalizer uses independent parameters for 'Q', center frequency, and boost/cut.

An external parametric equalizer could also be used to remove unwanted "scratchy" sounds.

Parametric equalizers are also sold as standalone outboard gear units.

Daniel N. Flickinger introduced the first parametric equalizer in early 1971.

These are implemented directly by each section of a parametric equalizer where they are explicitly adjusted.

A parametric equalizer, on the other hand, has one or more sections each of which implements a second-order filter function.

This can best be done using a parametric equalizer tuned to that very frequency with its amplitude control sharply reduced.

The gain of a parametric equalizer is reduced as the level of the sibilance increases.

Graphic and parametric equalizers have much more flexibility in tailoring the frequency content of an audio signal.

Parametric equalizers are often built into each channel in mixing consoles and are also available as separate units.

These amps offer an extremely flexible parametric equalizer as well as a strong, high-headroom clean tone.

As well, these amplifiers often contain feedback-suppressing devices, such as notch filters or parametric equalizers.

Custom five-band parametric equalizer with savable presets.

A variant of the parametric equalizer is the semi-parametric equalizer, also known as a sweepable filter.

The oldest audio subliminal technique uses a voice that follows the volume of the music so subliminals are impossible to detect without a parametric equalizer.

Speck's current product lineup includes parametric equalizers, mixing consoles, analog line mixers, and microphone preamplifiers.

At the same time, younger brother Rob Silfvast designed the Crescendo's 4-band parametric equalizer, one of its hallmark technologies.

A peak EQ filter makes a peak or a dip in the frequency response, commonly used in parametric equalizers.

Parametric equalizers require more expertise than graphic equalizers, and they can provide more specific compensation or alteration around a chosen frequency.

Parametric equalizers are multi-band variable equalizers which allow users to control the three primary parameters: amplitude, center frequency and bandwidth.

Another application is measurement of the effectiveness of an electronic filter with extremely narrow passband, such as a notch filter in a parametric equalizer.
