PARAMETRIC EQUALIZER
With the parametric equalizer it is possible to set more parameters for every section than the graphic equalizer.
WARNING:
the parameters of a section of the parametric equalizer are linked to each other. When a parameter is
changed, it may cause changes to other parameters. Be careful when changing the parameters.
WARNING:
when changing from the parametric type to the graphic type, some set parameters can be modified
according to the constraints imposed by the graphic equalizer (filter type, frequency, form factor (Q), ...).
Remark:
when the equalizer is in parametric mode, the frequency response of the single section currently selected is
shown on the graph with a white dotted line.
Selecting the desired section it is possible to change the different parameters of this section. The first parameter you
can set is the type of section filter.
Remark:
not all sections have all types of filters available.
After selecting the filter type it is possible to set the Gain, Frequency and the Form factor (Q), except for Flat where it
is not possible to set any parameters.
The minimum and maximum Gain is -12 dB and +12 dB.
For Low shelving the minimum and maximum frequency is 20 Hz and 1000 Hz respectively; for High shelving the
minimum and maximum frequency is 8000 Hz and 20000 Hz respectively; for Peaking the minimum and maximum
frequency is 20 Hz and 20000 Hz.
The minimum and maximum value for the Peaking Form factor (Q) is 0.5 and 16; for shelving types (low and high) the
Form factor (Q) ranges from 0.5 to 1.41.
