Each filter has the following editable parameters:
Type of filter
Allows to choose three different types of filter and different attenuation slopes:
Butterworth (But) at 6, 12, 18 or 24dB per octave,
Bessel (Bes) at 12, 18 or 24dB per octave,
Linkwitz-Riley (LR) a 12, 24 or 48dB per octave.
By setting the Thru value, the filter is disabled and the signal passes without its frequency being al-
tered.

Crossover frequency
Allows to choose the filter cutoff frequency.

Phase
Allows fine control (in 5° steps) of the signal’s phase.
The effect of this control is summed with that of the Output Polarity function (0°÷180°).
In this way it’s possible to adjust the phase of each individual output with 5° steps through a full 360°.
N.B.: this control is only in the Low-Pass Filter window.
