The Design of Active Crossovers is a unique guide to the design of high-quality circuitry for splitting audio frequencies into separate bands and directing them to different loudspeaker drive units specifically designed for handling their own range of frequencies. Traditionally this has been done by using passive crossover units built into the loudspeaker boxes; this is the simplest solution, but it is also a bundle of compromises. The high cost of passive crossover components, and the power losses in them, means that passive crossovers have to use relatively few parts. This limits how well the crossover can do its basic job. Active crossovers, sometimes called electronic crossovers, tackle the problem in a much more sophisticated manner. The division of the audio into bands is performed at low signal levels, before the power amplifiers, where it can be done with much greater precision. Very sophisticated filtering and response-shaping networks can be built at comparatively low cost. Time-delay networks that compensate for phyical misalignments in speaker construction can be implemented easily; the equivalent in a passive crossover is impractical because of the large cost and the heavy signal losses. Active crossover technology is also directly applicable to other band-splitting signal-processing devices such as multi-band compressors. The use of active crossovers is increasing. They are used by almost every sound reinforcement system, by almost every recording studio monitoring set-up, and to a small but growing extent in domestic hifi. There is a growing acceptance in the hifi industry that multi-amplification using active crossovers is the obvious next step (and possibly the last big one) to getting the best possible sound. There is also a large usage of active crossovers in car audio, with the emphasis on routing the bass to enormous low-frequency loudspeakers. One of the very few drawbacks to using the active crossover approach is that it requires more power amplifiers; these have often been built into the loudspeaker, along with the crossover, and this deprives the customer of the chance to choose their own amplifier, leading to resistance to the whole active crossover philosophy. A comprehensive proposal for solving this problem is an important part of this book. The design of active crossovers is closely linked with that of the loudspeakers they drive. A chapter gives a concise but complete account of all the loudspeaker design issues that affect the associated active crossover. This book is packed full of valuable information, with virtually every page revealing nuggets of specialized knowledge never before published. Essential points of theory bearing on practical performance are lucidly and thoroughly explained, with the mathematics kept to an essential minimum. Douglas' background in design for manufacture ensures he keeps a wary eye on the cost of things. Features: Crossover basics and requirements The many different crossover types and how they work Design almost any kind of active filter with minimal mathematics Make crossover filters with very low noise and distortion Make high-performance time-delay filters that give a constant delay over a wide range of frequency Make a wide variety of audio equaliser stages: shelving, peaking and notch characteristics All about active crossover system design for optimal noise and dynamic range There is a large amount of new material that has never been published before. A few examples: using capacitance multipliers in biquad equalisers, opamp output biasing to reduce distortion, the design of NTMTM notch crossovers, the design of special filters for filler-driver crossovers, the use of mixed capacitors to reduce filter distortion, differentially elevated internal levels to reduce noise, and so on. Douglas wears his learning lightly, and this book features the engaging prose style familiar from his other books The Audio Power Amplifier Design Handbook, Self on Audio, and the recent Small Signal Audio Design.

In the second edition of Electronics for Guitarists author Denton Dailey teaches the basic theory of operation and design principles of analog guitar signal processing circuits and amplifiers. The design and operation of common effects circuits such as tone controls, preamps, phasers, flangers, envelope followers, distortion and overdrives are covered, as are both solid-state amplifiers and power supplies. Written primarily for the guitarist, this book balances coverage of theoretical analysis and design while providing many examples of practical experimental circuits. The main thrust of the material is analog circuitry, focusing on fundamental principles of transistors, integrated circuit and vacuum tube-based amplifier operation and theory, and operation of typical guitar signal processing effects circuits. Updated to the new edition include: • New coverage of tone control circuits, MOSFETS and their applications as small-signal amplifiers, rail splitters and charge pumps, amplifiers using germanium transistors, and tube power amp design • Expanded coverage of numerous subjects such as vacuum tube power supplies, the digital oscilloscope, Darlington and Sziklai transistors, and signal spectra and transfer function symmetry • Additional examples of various circuits such as overdrive, distortion, chorus, delay, tremolo and auto-wah circuits as well as amplifier design Electronics for Guitarists is ideal for the musician or engineer interested in analog signal processing. The material is also useful to general electronics hobbyists, technologists and engineers with an interest in guitar and music-related electronics applications.

Linear Audio Vol 0 is our first printed bookzine dedicated to technical audio and perception. This first issue has more than 12 insightful articles by an international team of authors: Solid State: Nelson Pass comes up with a tribute to the single ended triode power amp by replacing hollow state with silicon carbide in The Arch Nemesis*, while Douglas Self cuts through the confusion and handwringing by showing how Inclusive Compensation can be successfully applied. Joachim Gerhard goes Down the Rabbit Hole to get the lowest MC-preamp noise this side of liquid helium cooling*. Tube technology: Air Polisois extends his DC-coupling and Common Transformer developments in the deceptively simple Mini-Simplex, while Stuart Yaniger gives you the definite deal on The Truth about the Humble Cathodyne. Meanwhile, Frank Blohbaum shows you A New Low-Noise Circuit Approach for Pentodes with his BestPenthode circuits. Loudspeakers and perception: Jean-Claude Gaertner embarked on a wide-ranging project for an active 4-way, DSP driven, remotely controlled system Project21. The first part describes the satellites. Siegfried Linkwitz contributes his landmark paper on STEREO - From live to recorded and reproduced - What does it take? - this should be the basis for many a discussion of what is and what is not possibly in stereo, and why. Test Equipment: Bob Cordell developed his Distortion Magnifier, a simple add-on to any distortion measurement setup increasing the resolution by 20 or even 40dB*. Book reviews: Andy Bryner reviews Douglas Self's latest opus Small Signal Audio Design and likes what he reads, while Bob Cordell's Audio Power Amplifier Design is waiting in the wings to be revealed. Tips & Tricks: If, like Ed Simon, you have more ic's and transistor types than you can keep track off, you'll love his IC holder notebook. Musings: Rene Wouda asks "Do you remember your first single?" . A bit tongue-in-cheek but thoughtful nevertheless.
