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:
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 application of the Stereo Imager is to widen the higher frequencies and nar-
row the lower frequencies. 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:

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.

Description
X-Over
Frequency
This determines the crossover frequency between the Hi and Lo band. Range is 100 Hz - 6 kHz. Frequen-
cies below this will be affected 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 activated 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 activated or not.
Solo switch This allows you to listen to the Lo and Hi bands separately, for reference purposes. “Normal” is the stan-
dard operating mode.
