Cluster Size

The Low Frequency Correction (Cluster Size) works on all the array’s objects. There is also a new advanced feature regarding the Cluster Size Correction: The Bass Shaper functionality.

It is unlockable by selecting Bass Shaper button (

) on the left-lower side of the graph.

This will substitute the Bass Shaper interface to the User Equalizer view, resulting as follows.

The Bass Shaper allows, starting form an existing Cluster Size Correction preset, the LF preset values to be customized, acting on three properties: LF Level, Frequency Slider and Strength.

“ LF Level ”: is a low shelf filter that act s on the frequencies under 200 Hz

“ Frequency Slider ”: if the “LF Level” has a negative gain, this slider moves the central frequency of a further and localized subtraction of gain from the global equalization; if “LF Level” has a positive gain, this slider moves the central frequency of a further and localized addition of gain to the global equalization. Higher is the presence of the positive or negative gain, higher is the localized addition or subtraction. “ Strength ”: this parameter gives a general boost to the Bass Shaper equ alization with an additional boost between 300 Hz and 800 Hz, useful to adapt the sound to the curvature of the array. It is therefore possible to create complex low frequency equalizations that, if performed with standard parametric equalizers, would require the control of a large number of parameters. The equalization made with Bass Shaper should always be accompanied by measures out in the field in order to verify the desired shape of the frequency spectrum.

Changing the value of at least one of these properties trigs t he LF Preset changing on a “live“ preset called “L*”

L* preset is unreachable using arrows control and if you decide to change the current preset in the traditional way (using arrow control) you will lose all the Bass Shaper changes made before. In order to save these changes you must copy them into one of two rewritable custom presets “C1” and “C2”. To do this you have to click “Save In” button specifying the destination custom preset ( ).

These two custom presets can be set using arrow control.
