Basic/Advanced
By default, the crossover is in basic mode, and shows the controls described below. Advanced mode
enables custom biquad programming for almost infinite flexibility in crossover filter implementation. This
is described in
Custom biquad programming
Cutoff Frequency
Sets the nominal cutoff frequency of the crossover. In actual fact, the crossover has a more or less gradual
transition from "full on" to "full off," as determined by the filter slope.
Filter type
Selects the type and slope of the filter. The steeper the slope, the more quickly frequencies above or
below the cutoff frequency are attenuated. There are three types of filter:
Butterworth (BW)
Available in 6, 12, 18, 24, 30, 36, 42, and 48 dB/octave, Butterworth crossover filters are 3 dB down
at the cutoff frequency.
Linkwitz-Riley (LR)
Available in 12, 24, and 48 dB/octave, Linkwitz-Riley crossover filters are 6 dB down at the cutoff
frequency.
Bessel
Available in 12 dB/octave only, a Bessel filter gives a more gradual roll-off through the crossover
region.
Bypass
Clicking on the Bypass button disables or enables that high pass or
low pass filter. The filter is bypassed when the button is "lit".
Each channel can be linked to one other channel. When a channel is linked to another, the crossover settings of
that channel are mirrored to the other. Typically, the corresponding drivers on the left and right channels are
linked: left and right tweeter, left and right woofer, and so on. To link a channel, select the other channel from
the drop-down menu at the top left of the Xover display, and click the Link checkbox.
