By
Douglas Self, Douglas Self has a worldwide reputation as a leading authority on audio amplifier design, but it is perhaps less well known that he has
devoted a good deal of study to small-signal circuitry, including many years as the chief design engineer at one of the major mixing
console manufacturers, where his achievements included winning a Design Council Award. His rigorous, skeptical, and thoroughly practical
approach to design has been applied to the small signal area as well, and some of the results to be found in this book.

of high-end audio amplifiers and contributor to Electronics World magazine, Douglas has worked with many top audio names, including Cambridge
Audio, TAG-McLaren Audio, and Soundcraft Electronics.

Description
This book is the essential reference for audio power amplifier designers and engineers. Author Douglas Self covers all the issues of
distortion and linearity, power supplies, protection, reliability and layout. He also tackles unusual forms of compensation and unexpected
sources of distortion such as capacitors and fuses.
This much expanded and updated Fifth Edition includes four NEW chapters, one
of them dedicated to the XD crossover-displacement principle, invented by the author, and used by Cambridge Audio. The book has a wealth
of new material on four-stage amplifier architectures, current-mirrors, power transistors with internal sensing diodes, amplifier bridging,
subtle distortion mechanisms, input stage common-mode distortion, double input stages, amplifier stability, output stages with gain,
transformers and hum fields, inrush current suppression, DC servo design, thermal protection, the subtleties of cooling fan control,
advanced line input stages, ultra-low-noise design, high and low-pass filtering, testing and safety, infra-red control, signal activation,
12V trigger, level indication and much more. There is significantly expanded material on professional power amplifiers as used in sound
reinforcement and PA applications.
This book is a must-have for audio power amplifier professionals and audiophiles, amateur constructors
and anyone with intellectual curiosity about the struggle towards technical excellence.
Audience:
Professional audio engineers, sound system designers, sound technicians,. Professional Audio Amplifier Designers and Engineers; High-end
