Excellent reference book. November 2, 2009 Perazzoli Guido Luis (Argentina) It is an excellent reference book for the DIYaudio enthusiast. It has very nice and USEFUL projects. A must!
Amazing Book! Very Instructive! October 9, 2009 Steven Gabriel Camara I'm a bit busy, so I will be short on the reviews, like I show on the rating stars "I Love It", the book is very easy to read and understand!
Excellent Resource for All Types of Audio Circuits October 1, 2009 Eric Boyer (Canada) This is an excellent resource for somewhat-experienced electronics hobbyists to make high-quality audio projects of all kinds. It's very readable, and all the required resources (such as schematics, PC board artwork, and basic explanations) are provided for all the projects.
Before going any further, I should clarify who this book is for. The reader will need good knowledge of intermediate circuit analysis (mesh-current analysis, node-voltage analysis, etc in large circuits), extensive knowledge of transistors and op-amps, extensive knowledge of capacitive circuits, some knowledge of inductors, a good grasp of the concepts of input and output impedance of circuits, and knowledge of circuit feedback (only if you plan on building an amplifier). Also, plenty of hands-on experience with circuit construction would really help. If you're unsure of your skill in any of those areas, I suggest not reading this book until you learn them because many things will go right over your head otherwise. If you're taking electrical engineering at university you'll probably be fine if you're in 3rd year, but I'd recommend waiting until 4th year so that you get a better grasp of everything. Note, however, that this book doesn't get into complicated math, the frequency domain, Laplace transforms, imaginary numbers, or any other complicated subjects like that, so don't worry if you're rusty in those areas.
Now on with the book. It starts out with a chapter discussing audio topics in general, such as how humans hear sound and the goals of a high-quality sound system, then discusses topics such as distortion, noise, frequency response, slew rate, and phase issues.
Chapter two is about balanced vs single ended audio signals, baluns, and volume control circuits (including digitally-controlled ones).
Chapter three is about preamplifiers. Several example schematics are provided, and circuits for RIAA equalization, loudness control, and audio balance are provided. Methods for power supply decoupling are also presented in this chapter.
The fourth chapter is about audio filters, and includes circuits for tone controls, active low-pass filters, equalizers (with one circuit having 24 bands), parametric equalizers, and phase-linear filters. This chapter also has a section with advice on what types of resistors and capacitors to use.
Chapter five is about headphone amplifiers. This chapter is very short and only includes two headphone amp circuits with minimal explanation. But, they are good amplifiers, and very little description is given because the next chapter is dedicated to amps.
The sixth chapter covers audio amplifiers. First I should note that I didn't fully read this chapter because I didn't know enough about transistors and circuit feedback at the time to be able to understand it well enough, so I don't know all the details about this chapter. However, upon skimming through it I found that there are several schematics for amplifiers ranging from about 10 watts up to 300. The explanations seem pretty good, but considering how complicated amplifier circuits can be I'm guessing that this chapter alone will not give the reader a very detailed knowledge of amplifiers. Rather, as Slone mentioned somewhere in the chapter, this chapter is only meant to give a brief description of amplifiers. For a better analysis, a dedicated book like Slone's "High-Power Audio Amplifier Construction Manual" should be read.
Chapter seven covers power supplies. The three main types of DC power supplies are discussed (linear regulated, switch-mode, and unregulated), as well as several topics surrounding power supplies, such as how big the power supply has to be for an amp of a given power level, methods of rectification, fusing, and capacitors. The chapter is split into two sections, one for amplifier power supplies and one for signal-processing circuit power supplies (aka, low power circuits), and schematics for several different power supplies are presented. Methods for making general-purpose bench-top power supplies are also discussed.
Chapter eight covers protection circuits, such as DC and transient speaker protection, soft-start, and clip-detection.
Chapter nine includes various miscellaneous audio circuits, such as display circuits (for example, an LED-based power level display), phase control circuits (mainly for subwoofer amplifiers), and delay circuits.
In chapter ten, Slone gives some very useful information for constructing circuits. The chapter starts with methods of dealing with hum and noise and how to ground everything properly. Slone then presents an excellent introduction to PC board fabrication, both by hand and by using software to print the circuit (which anyone with a printer can do). The next section is on heatsinks and how to choose one of a proper size, and the chapter finishes with a short discussion of project enclosures.
The book ends with a few appendices. Appendix A is a comprehensive glossary of pretty much every term used in the book; appendix B is an extremely useful list of suppliers for electronics parts, audio equipment, project enclosures, and pretty much anything you'll need for a DIY project; and appendix C is a compilation of the PC board artwork that didn't fit well in the other parts of the text.
The above lists pretty much every subject, circuit, and project in the book, except for a few minor ones that I may have missed. With the knowledge and circuits presented in this book, anybody with enough skill and previous knowledge should be able to build an entire high-powered, hi-fi audio system from scratch. I've only had the chance to build a few of the smaller projects presented in this book, but they worked quite well.
A fairly common complaint about this book is that some of the components that are used in the projects are hard to find (particularly because Seal Electronics, the author's company and the source of kits for many of these projects, has gone out of business). Although I haven't checked every project specifically, I do know that most of the time when searching for a semiconductor, where there's a will there's a way. If you can't find a specific transistor, op-amp, etc then there are many resources on the internet for finding an equivalent component. Even if you can't get an exact match, you can almost always come very close.
I would highly recommend this book to anyone who is interested in how audio systems work, particularly if you want to build your own systems. BUT, only buy this book if you are knowledgeable enough with all the concepts I listed in the second paragraph of this review.
First-rate resource for the budding DIY audio enthusiast April 5, 2008 A. Vienot (Colorado, USA) 1 out of 1 found this review helpful
Slone covers a wide range of audio projects in this book: amplifiers, preamplifiers, filters, and protection circuits. The reader is assumed to understand basic electronics terminology, but everything else is explained point by point. An easy-to-read format supplies just enough theory for understanding the circuit, then goes right to the practical application. Slone even provides 1:1 scale artwork of numerous designs for those who want to etch their own circuit boards. For those wanting to go deeper into amplifier theory than what is presented here, this book is an execllent companion for Slone's in-depth treatment of the subject, the High-Power Audio Amplifier Construction Manual.
