The MClass Equalizer

The MClass Equalizer consists of two independent, fully parametric bands plus high and low shelving bands and a lo cut switch.

This is most often used as an insert effect, in mono or stereo.

Activating the separate EQ bands

The separate bands are organized as vertical strips on the panel, in the following order (from left to right): Lo Cut/Lo Shelf/Parametric 1/Parametric 2/Hi Shelf.

You activate the separate bands by clicking the button at the top of each strip (none of the bands are activated by default).

Lo Cut

The Lo Cut switch will simply cut frequencies below 30 Hz (by 12 dB/Octave). This is useful for removing low frequency “rumble”.

When you are using the MClass Equalizer with a compressor or Maximizer, activating the Lo Cut switch prevents subsonic sound from “topping” the compressor/limiter, and allows them to operate as efficiently as possible.

Parametric 1-2 parameters

A parametric equalizer will boost or cut frequencies around the selected frequency. The following parameters are available for both the parametric bands:

| Parameter	| Description
Frequency	This determines the center frequency of the EQ, i.e. at which frequency the level should be decreased or increased. The range is 39 Hz to 20 kHz.
Gain	Specifies how much the level of the selected frequency range should be boosted or cut. The gain range is ±18 dB.
Q	This governs the width of the affected area around the set center frequency. The higher the value, the narrower the affected frequency range.

Lo/Hi Shelf parameters

A shelving equalizer will boost or cut frequencies below or above the selected frequency.

The following parameters are available for the Lo/Hi Shelf bands:

| Parameter	| Description
Frequency	Frequencies below (Lo Shelf) or above (Hi Shelf) the selected frequency will be boosted or cut. • The Lo Shelf range is 30 Hz to 600 Hz. • The Hi Shelf range is 3 kHz to 12 kHz.
Gain	Specifies how much the level should be boosted or cut. The gain range is ±18 dB.
Q	This governs the slope of the shelving curve. The higher the value, the steeper the curve slope. High Q settings will also produce a “bump” in the opposite cut/boost direction at the set frequency.

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.
