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 1st- through 4th-order slopes, or

Linkwitz-Riley filters with 2nd- or 4th-order slopes, or combinations

thereof.

Two-Way Crossovers

Figure 8-4

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.
