Here is the Third Edition of my book on with audio small signal design, which is the amplification and control of audio in the analogue domain, where the operations are performed with op-amps or discrete transistors, usually working at a nominal level of 1 Volt or less. It is a unique collection of detailed information on small-signal audio, and has now been enlarged by 50%. All of the new material is wholly original and derived from my own researches; most of it has never been published before.

The first few chapters cover the principles of high-quality small-signal design, moving on to look closely at first hifi preamplifiers, and then mixing consoles. These two genres were chosen partly because they are of wide interest in themselves, but mainly because they use a large number of different functional blocks, with very little overlap between them. They cover a wide range of circuit functions that will be useful for all kinds of audio systems. You will find out how to adapt or design these building-blocks, and how to put them together to form a system. You should then be able to design pretty much anything in the small-signal audio field.
