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
value, the filter is disabled and the signal passes without its frequency being al
Thru
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 .
Note:
this control is only in the Low-Pass Filter window.
The values can be set in the following ranges:
