Crossover
Each output channel has independent high pass and low pass filters. Click on the
Xover
button to open the
crossover settings window:
Crossovers “split” the frequency band to send to different drivers. In a two
-way loudspeaker, a
low pass
filter is
used to remove high frequencies from the signal sent to the woofer, and a
high pass
filter is used to remove low
frequencies from the signal sent to the tweeter. In a three-way speaker, the midrange driver will use both the
high pass and low pass filters. Crossover filters can also be used to limit low frequency content delivered to a
speaker or subwoofer, to help protect it from over-excursion.
Unlike conventional analog crossovers, the flexibility of DSP allows a completely arbitrary mix of different filter
slopes and types. Filters can be set at any frequency, or disabled completely. This allows maximum flexibility in
matching your crossover to the acoustic characteristics of the loudspeaker drivers.
The current channel is displayed in orange, with the others displayed
in grey. Hovering the mouse over the curve brings up an overlay
showing the frequency and the attenuation at that frequency.
