PEQ-2 Two Band Parametric EQ

While there is a simple two-band shelving equalizer available for each channel in the mixer, the PEQ-2 gives you much more precise control over the tone color. The device consists of two independent, fully parametric equalizers and is most often used as an insert effect, in mono or stereo.

About the two EQ modules

The two independent EQs are labeled “A” and “B”.

•	EQ A is always active (provided that the effect device is in “On” mode and that you have set the Gain to a value other than 0).

•	To activate EQ B, click the button next to the EQ B parameters, so that the LED lights up.

If you only use one EQ, it’s a good idea to turn EQ B off, to conserve computer power.

Parameters

For both EQs (A and B), the following parameters are available:

| Parameter	| Description
Frequency	This determines the center frequency of the EQ, e.g. at which frequency the level should be decreased or increased. The range is 31 Hz to 16 kHz.
Q	This governs the width of the affected area around the set center frequency. The higher the value, the narrower the affected frequency range.
Gain	Specifies how much the level of the selected frequency range should be boosted (positive values) or lowered (negative values). The gain range is ±18 dB.

About the graphic display

The graphic display to the left in the device panel shows the frequency response curve as set by the EQ parameters. This gives a visual feedback and helps you tailor the EQ settings.

CV Inputs

The following CV inputs are available on the back panel of the device:

•	Freq 1 CV.

Allows you to control the frequency of EQ A from another device, creating subtle or dramatic EQ sweeps depending on the Q and Gain settings.

•	Freq 2 CV.

Allows you to control the frequency of EQ B in the same way.
