Crossovers

Purpose

Crossovers divide the frequency spectrum into two or more bands that are processed independently and typically sent to separate power amplifiers. Crossovers are constructed of Low Pass and High Pass Filters, and their controls relate to the corresponding controls of their component filter sections. Crossover devices can have 2, 3 and 4 bands and maximum slopes of 24, 36 and 48dB/octave. Crossovers consume DSP resources proportional to the number of bands and their maximum filter slope. Select the smallest Crossover which fulfills the requirements for your application. Once compiled, filter slopes may be adjusted downward with the Slope Controls but no DSP resources will be recovered by doing this.

Notes:

• There is a gain control for each band, whilst the frequency controls divide the bands.
• There are only three crossover points in a 4-way system. For a 3-way system, there are two, and so on.
