THE EFFECT DEVICES

336

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:

Lo/Hi Shelf parameters

A shelving equalizer will boost or cut frequencies below or above the selected fre-

quency.

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

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.

The MClass Stereo Imager

The MClass Stereo Imager splits the signal into two frequency bands; “Hi” and “Lo”

and allows you to widen or narrow the stereo image of each band. A typical applica-

tion of the Stereo Imager is to widen the higher frequencies and narrow the lower fre-

quencies. This will make the bass end “tight” whilst “opening up” the higher

frequencies.

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

! The MClass Stereo Imager does not create stereo from mono input! For

the device to work properly it must connected with stereo in/out, and the

input signal must contain a stereo audio signal.

Parameters

The following parameters are available:

Connections

Apart from standard L/R inputs and outputs, there are also “Separate” L/R outputs on

the back panel. The Separate outputs can either carry the Lo or Hi band output, which

is set by the switch beside the outputs. These outputs can be used to apply process-

ing separately to either the Lo or Hi band.

✪ If you set the Solo switch to “Lo” and the Separate output switch to “Hi”,

the device will operate as a basic crossover filter, delivering the Lo band

signal from the main output and the Hi band signal from the Separate

out.

Parameter

Description

Frequency This determines the center frequency of the EQ, i.e. at which fre-

quency 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 fre-

quency range.

Parameter

Description

Frequency Frequencies below (Lo Shelf) or above (Hi Shelf) the selected fre-

quency 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.

Parameter

Description

X-Over

Frequency

This determines the crossover frequency between the Hi and Lo

band. Range is 100 Hz - 6 kHz. Frequencies below this will be af-

fected by the Lo Width setting; frequencies above will be affected by

the Hi Width setting.

Lo Width This adjusts the stereo width for the Lo band. Turn anti-clockwise to

narrow the stereo width (i.e. to make it more “mono”), and clockwise

to widen the stereo image. Center position means no change from

original signal. The “Active” LED indicates whether Low Width is acti-

vated or not. Note that for the Lo band, it is more common to narrow

the stereo image, as the low frequency content in a mix is usually

mixed center and can become less defined if widened.

Hi Width This adjusts the stereo width for the Hi band. Turn anti-clockwise to

narrow the stereo width (i.e. to make it more “mono”), and clockwise

to widen the stereo image. Center position means no change from

original signal. The “Active” LED indicates whether Hi Width is acti-

vated or not.

Solo switch This allows you to listen to the Lo and Hi bands separately, for refer-

ence purposes. “Normal” is the standard operating mode.
