Description:
The Design of Active Crossovers is a unique guide to the design of high-quality circuitry for splitting audio frequencies into separate bands and directing them to different loudspeaker drive units specifically designed for handling their own range of frequencies. Traditionally this has been done by using passive crossover units built into the loudspeaker boxes; this is the simplest solution, but it is also a bundle of compromises. The high cost of passive crossover components, and the power losses in them, means that passive crossovers have to use relatively few parts. This limits how well the crossover can do its basic job.

This book is packed full of valuable information, with virtually every page revealing nuggets of specialized knowledge never before published. Essential points of theory bearing on practical performance are lucidly and thoroughly explained, with the mathematics kept to an essential minimum. Douglas' background in design for manufacture ensures he keeps a wary eye on the cost of things.

Features:

  • Crossover basics and requirements
  • The many different crossover types and how they work
  • Design almost any kind of active filter with minimal mathematics
  • Make crossover filters with very low noise and distortion
  • Make high-performance time-delay filters that give a constant delay over a wide range of frequency
  • Make a wide variety of audio equaliser stages: shelving, peaking and notch characteristics
  • All about active crossover system design for optimal noise and dynamic range
