Parametric Equalizer Component

The Parametric Equalizer is a variable equalizer allowing you to individually adjust the Gain, Bandwidth and center Frequency of up to 32 frequency bands. You can also Bypass individual bands. Master controls, affecting all bands, include Bypass, Invert, Mute and Gain. Additionally, you can change any or all of the bands to either a high or low-shelf equalizer, allowing you to vary the gain of all frequencies, as a group, above or below a selected frequency. At the selected Frequency, the gain changes approximately +3dB or -3dB depending on wether the shelf is adding or reducing gain.

Response Panel

The Response panel provides vertical and horizontal cross-hairs with a dynamic frequency and level read-out. Place the mouse courser over the graph to activate the cross-hairs. When the Phase control is activated, the horizontal cross-hair line to the left of center represents the normal curve, the right side represents the phase curve. The readout is only for the normal curve.

X-Axis = Frequency, 20Hz to 20kHz

Y-Axis Left = dB, -24dB to 24dB

Y Axis Right = Phase, -180° to 180°

All (Bands)

A toggle button that activates a graphical display all bands of the equalizer. When the button is not enabled, the Response Panel displays a composite of all the bands. The composite cannot be turned off.

Bandwidth

(Octave)

Sets the Bandwidth of an individual band of the equalizer. This is not active when either Low-shelf or High-shelf Type is selected.

Range = 20 to 20000

Type

Selects the type of equalizer for that band.

Default = Parametric

Choices - High-shelf, Low-shelf, Parametric

1. The default is different for each band, and depends on number of bands.
