Crossover
Figure 8-3
Two-way crossover component.
Crossovers (see Figure 8-3) are used to divide the audio signal into
multiple bands appropriate for different types of loudspeakers or
loudspeaker elements. In QuickMAPs, 2-way, 3-way, and 4-way
crossovers may exist. Each of these crossovers may be implemented
using Bessel or Butterworth filters with 1
st
- through 4
th
-order slopes, or
Linkwitz-Riley filters with 2
nd
- or 4
th
-order slopes, or combinations
thereof.
Two-Way Crossovers

Two-way crossover implementation.
In the ISP-100, 2-way crossovers are implemented as shown in
Figure 8-4.
Custom crossovers
other than those
available from the
crossover
component can be
constructed by
using the filter
component.
