The Design of Active Crossovers

CHAPTER 19

An Active Crossover Design

Here I present an active crossover design that will illustrate a good number of the principles and techniques put forward in this book. A design that demonstrated all of them would be a cumbersome beast, so I have aimed instead to show the most important of them while also providing a practical and adaptable design which will be of use in the real world.

The design is a generic crossover that can be adapted to a wide range of applications by changing its parameters and its configuration. The crossover frequencies can be changed simply by altering component values, and circuit blocks for equalisation or time delay can be added or removed, with due care to preserve absolute phase, of course. Since widely varying ...
