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
- There is a large amount of new material that has never been published before. A few examples: using capacitance multipliers in biquad equalisers, opamp output biasing to reduce distortion, the design of NTMTM notch crossovers, the design of special filters for filler-driver crossovers, the use of mixed capacitors to reduce filter distortion, differentially elevated internal levels to reduce noise, and so on.
