This book addresses the widened scope of technology that has become available to the audio designer over the last 35 years. Including expanded prefaces to each article, the author provides background information and circuit commentary. Douglas Self has spent many years working at the top level of design in the professional audio and hifi industries and has taken out a number of patents in the field of audio technology.

Small Signal Audio Design is a highly practical handbook providing an extensive repertoire of circuits that can be assembled to make almost any type of audio system. This fully revised fourth edition offers wholly new content on internally balanced audio design, electret microphones, emitter-follower stability, microphony in capacitors, and much, much more. This book continues the engaging prose style familiar to readers, as you learn why mercury-filled cables are not a good idea, the pitfalls of plating gold on copper, and what quotes from Star Trek have to do with PCB design. Learn how to: make amplifiers with apparently impossibly low noise design discrete circuitry that can handle enormous signals with vanishingly low distortion transform the performance of low-cost-opamps build active filters with very low noise and distortion, while saving money on expensive capacitors make incredibly accurate volume controls make a huge variety of audio equalisers make magnetic cartridge preamplifiers that have noise so low it is limited by basic physics, by using load synthesis sum, switch, clip, compress, and route audio signals build simple but ultra-low noise power supplies be confident that phase perception is not an issue Including all the crucial theory, but with minimal mathematics, Small Signal Audio Design is the must-have companion for anyone studying, researching, or working in audio engineering and audio electronics.

Active crossovers are used by almost every sound reinforcement system and every recording studio monitoring set-up; but the use of active crossovers is rapidly expanding. This new edition, presents all the updates to loudspeaker technology and crossover design. The edition expands on loudspeaker configurations and design issues, sound reinforcement issues, more on lowpass and highpass filters, and may other filters. This new edition is a must read for anyone wanting comprehensive practical knowledge.

Presents the first comprehensive book on electronics for vinyl High-level, practical information with minimal mathematics Includes topics such as low-noise amplification, proper cartridge loading, equalisation for archival recordings, and more Includes tricks and innovations from an expert author

This is the essential book reference for amplifier designers. Douglas Self covers all the design issues of noise, distortion, power supply rejection, protection, reliability, and layout. He describes advanced forms of compensation that give dramatically lower distortion. This edition is much expanded, and packed with new information. It is a must-have for audio power amplifier professionals and audiophiles, amateur constructors and anyone with intellectual curiosity about the struggle towards technical excellence. New to the sixth edition: The characteristics of the audio signal The principles of distortion Feedback intermodulation distortion Non-switching output stages VAS distortion explained Push-pull VAS configurations Output-inclusive compensation In addition, five amplifier design examples that illustrate important design principles are examined and measured in detail. These can be straightforwardly adapted to specific requirements. This new edition also includes a wealth of material on the XD crossover-displacement principle (invented by the author and in use by Cambridge Audio), four-stage amplifier architectures, error correction, current-mirrors, power transistors with internal sensing diodes, amplifier bridging, input-stage-common-mode distortion, amplifier stability, output stages with gain, inrush current suppression, DC servo design, thermal protection, cooling fan control, advanced line input stages, testing and safety, infrared remote control, signal activation, 12V trigger control, the history of solid-state amplifiers and much more. Simple procedures for heatsinking and power supply design are given.
