The Design of Active Crossovers

CHAPTER 14

Active Crossover System Design

So far we have looked at the design of the functional blocks that go together to make an active crossover. It is now time to look at putting them together into a complete system. This involves not only selecting the optimal types of circuit block to perform the required crossover functions, but also considerations about what order in which to place them in the signal path, and what nominal signal levels to operate them at. This chapter also covers minor crossover functions such as output level controls and channel muting switches.

The actual crossover functions of filtering and equalisation make up the main part of a crossover’s circuitry, but other functions are required to make ...
