Douglas Self

Douglas Self is a British electronics engineer and author with a particular interest in audio. He received a first class honours degree in engineering from Cambridge University, and then studied psychoacoustics at Sussex University.[1] He is the author of six books on audio electronics, published by Focal Press.[2] He has also contributed many articles to Wireless World magazine, some of which were compiled into a book along with articles by Peter Baxandall.[3][4][5]

Known forAuthor, Electronic Engineer

He has taken out a number of audio-related patents, including for a "crossover displacement circuit".[1][6]

He has worked with several major companies, including Cambridge Audio, TAG-McLaren Audio, and Soundcraft Electronics.[7] Circuit Cellar website described him as a 'renowned audio specialist' when discussing a design he created for Elektor magazine.[8] He developed the concept of a "blameless" amplifier in which all the main sources of distortion are reduced to negligible levels.[3]

Self's books have been well received. His Audio Power Amplifier Design Handbook was recommended by Walt Jung and described as "famous" by audio website hifisonix.[9][10] The second edition of his Small Signal Audio Design received a very positive review in Sound on Sound magazine.[11]
