4 - EDITING WITH DSX
The two columns represent the low cut ( High Pass Filter ) and higher cut ( Low Pass Filter ) in which
you can configure crossover frequencies, the type of filter used for CrossOver and order of each filter to adjust
the slope.
To edit the values simply go to the box and put the desired values with the keyboard or modify them with
the mouse click up or down. The change will take effect on the value or press Enter to leave the box.
Select the channel on the "Modify" buttons. Beside them you will have the labels with the name of each
output. As in PEQ , the display will show at the bottom the value of frequency and magnitude or Phase filter
crossover in the current mouse position.
We have the following filters and slopes:
 Bypass No filter.
 Linkwitz-Riley 12dB, 24dB, 36dB and 48dB / Octave
 Butterworth 12dB, 24dB, 36dB and 48dB / Octave
 Bessel 12dB, 24dB, 36dB and 48dB / Octave
To choose the type of filter, High Pass or Low Pass of each route, you will select the desired option in
the drop-down menu, changing type of filter and Order (being the slope of the filter in dB / Oct = 6 x order).
We have 8 filters of 2nd order by CrossOver. Four for the lower cut and four for high cut. You can go up
to 8th Order by cut.
In case you do not want any cut on the signal, simply leave the type of filter in Bypass , in one or both
filters.
The cut-off frequencies of the filters are set at points of -3 dB for Bessel and Butterworth filters, and -
6 dB for Linkwitz-Riley .
When you put the same type of filter in a Low Cut channel and a High Cut on another channel with the
same frequency in both, to get a correct amount of signal summon, it will require reversing the phase towards
lower frequencies when using:

Butterworth of 2nd order at same frequency cut in both ways.
 Linkwitz-Riley of 2nd order at same frequency cut in both ways.

Bessel of 2nd order at same frequency cut in both ways.
 Bessel of 2nd order in the Low Cut and 4th order on High Cut (or viceversa) at the same
frequency cut.
