Crossover settings
Each output channel has independent high pass and low pass filters. Click on the
Xover
button to open the
crossover settings window:
By default, the crossover filters are bypassed (disabled). Click on the
Bypass
button to enable and disable a
crossover filter. There is one filter for high pass (low cut) and one for low pass (high cut). The above example
shows a pair of filters for the subwoofer channel with an 18 Hz high pass filter and an 80 Hz low pass filter.
Each filter can be set to one of a range of filter types and slopes. The filter type determines the shape of the
filter around the crossover point, and the filter slope (expressed in dB/octave) determines how steep the filter
cutoff is. The available filter types and slopes are:
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.
