Key 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.
