9.3.4 Crossover
Each output channel has independent high pass and low pass filters. See the
Plugin configuration guide
for some
example uses of crossover 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. When integrating a subwoofer, high pass filters are used on the
speakers and a low pass filter on the subwoofer. A crossover filter 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.
