Or, get it for Kobo Super Points! See if you have enough points for this item. With ample coverage of preamplifiers and mixers and a new chapter on headphone amplifiers, this practical handbook provides an extensive repertoire of circuits that can be put together to make almost any type of audio system. A resource packed full of valuable information, with virtually every page revealing nuggets of specialized knowledge not found elsewhere. Essential points of theory that bear on practical performance are lucidly and thoroughly explained, with the mathematics kept to a relative minimum. Douglas' background in design for manufacture ensures he keeps a wary eye on the cost of things.
I have kept the lupine from the lobby for many years by designing things to sell at a profit, so I have been able to include quite a few non-obvious ways to save money. An eye for economy is not merely a negative influence. I have tried to ensure that all the essential points of theory that bear on practical performance are explained, with the mathematics kept to an essential minimum, but I have no intention of trying to create a basic electronics textbook — there are plenty of good ones about already.
I do advise, however, that you get the basic theory straight before you try to make use of the circuitry and concepts here. Small-signal design is very often based on op-amp circuitry, the great advantage being that all the tricky details of low-noise and almost distortion-free amplification are confined within the small black carapace of a This op-amp is, for very good reasons, employed more than Preface xv any other in quality audio design, and I make great use of it here.
In the course of compiling this work, it has been brought home to me just what a bargain the is. There are, however, times when circuitry built with discrete transistors gives better results.
You may need more voltage swing than is available between op-amp supply rails, or it may be inconvenient to provide such rails, or you may want to do it purely for marketing purposes. I have therefore included a chapter on the design of discrete transistor stages.
This contains a wealth of little-known techniques, ranging from some of the lesser-known quirks of the simple emitter-follower to the design of complete op-amps from discrete devices.
It is sometimes highly advantageous to combine discrete devices and IC op-amps in the same feedback loop, to exploit the best qualities of each. When you need very low noise, say for a moving-coil phono amplifier, you have transistors followed by an op-amp. When you need high output current, say for driving headphones, you have an op-amp followed by transistors.
Many examples of this approach are scattered through the book. An important strand in this book is low-impedance design. By minimizing circuit resistances the contribution of Johnson noise is reduced, and conditions set for the best semiconductor noise performance.
Op-amp common-mode distortion and crosstalk are also reduced. The notion is not exactly new as some people would have you believe but has been used explicitly in audio circuitry for at least 20 years. This approach relies on amplifiers that can drive heavy loads at very low distortion, and here again the is extremely useful.
In this book you will find many examples of low-impedance design. What you will not find here is any truck with the religious dogma of audio Subjectivism: the directional cables, the oxygen-free copper, the World War One vintage triodes and all the other depressing paraphernalia of pseudo- and anti-science.
If you want to know more about my experiences and reasoning in this area, there is a full discussion in my earlier book, the Audio Power Amplifier Design Handbook. I have included a few historical vignettes both where they are of interest in themselves, and where they also shed light on some general principles of design. I have tried to avoid FGAs Frequent Gratuitous Acronyms but a few are used extensively so more useful text can be squeezed in.
They are listed after this Preface. None of them, I think, will cause any great confusion. I try to give value for money, so introductory material has been cut to a minimum, and many a rolling elegiac sentence has been ruthlessly culled to fit in another hard fact.
These are inevitably the result of relatively few measurements and are intended to be illustrative rather than defining a figure for all time. When op-amp properties were involved I have been careful to use high-quality parts from the well-known manufacturers rather than me-too parts of doubtful provenance.
Your mileage may vary, but I think not by much. The data here has been gathered over several years. It would have been a Sisyphean task to repeat all the measurements, so some graphs look a little agricultural graphically, but they have at least a certain gritty realism.
I have a website www. I really mean this; I have already written another thirty pages or so on both discrete and opamp design significantly extending the material in this book. From there you can contact me, so please let me know if you think something is wrong, or an important topic is missing, or if you have any other suggestions as to how to improve this book that do not involve combustion.
