Douglas Self – författare

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 compensationIn 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.

All the design and development inspiration and direction an audio engineer needs in one blockbuster book! Douglas Self has selected the very best sound engineering design material from the Focal and Newnes portfolio and complied it into this volume. The result is a book covering the gamut of sound engineering.The material has been selected for its timelessness as well as for its relevance to contemporary sound engineering issues.

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 capacitorsmake incredibly accurate volume controls make a huge variety of audio equalisersuse load synthesis to make magnetic cartridge preamplifiers that have noise so low it is limited by basic physicssum, switch, clip, compress, and route audio signals build simple but ultra-low noise power suppliesbe confident that phase perception is not an issueIncluding all the crucial theories, 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.

Electronics for Vinyl is the most comprehensive book ever produced on the electronic circuitry needed to extract the best possible signal from grooves in vinyl. What is called the "vinyl revival" is in full swing, and a clear and comprehensive account of the electronics you need is very timely. Vinyl reproduction presents some unique technical challenges; the signal levels from moving-magnet cartridges are low, and those from moving-coil cartridges lower still, so a good deal of high-quality low-noise amplification is required.Some of the features of Electronics for Vinyl include:integrating phono amplifiers into a complete preamplifier;differing phono amplifier technologies; covering active, passive, and semi-passive RIAA equalisation and transconductance RIAA stages;the tricky business of getting really accurate RIAA equalisation without spending a fortune on expensive components, such as switched-gain MM/MC RIAA amplifiers that retain great accuracy at all gains, the effects of finite open-loop gain, cartridge-preamplifier interaction, and so on;noise and distortion in phono amplifiers, covering BJTs, FETs, and opamps as input devices, hybrid phono amplifiers, noise in balanced MM inputs, noise weighting, and cartridge load synthesis for ultimately low noise;archival and non-standard equalisation for 78s etc.;building phono amplifiers with discrete transistors;subsonic filtering, covering all-pole filters, elliptical filters, and suppression of subsonics by low-frequency crossfeed, including the unique Devinyliser concept;ultrasonic and scratch filtering, including a variety of variable-slope scratch filters;line output technology, including zero-impedance outputs, on level indication for optimal setup, and on specialised power supplies; anddescription of six practical projects which range from the simple to the highly sophisticated, but all give exceptional performance.Electronics for Vinyl brings the welcome news that there is simply no need to spend huge sums of money to get performance that is within a hair’s breadth of the best theoretically obtainable. But you do need some specialised knowledge, and here it is.
