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.

What is called the \"vinyl revival\" is in full swing, and a clear and comprehensive account of the electronics you need is very timely. Vinyl reproduction presents some unique technical challenges; the signal levels from moving-magnet cartridges are low, and those from moving-coil cartridges lower still, so a good deal of high-quality low-noise amplification is required.  Some of the features of Electronics for Vinyl include:    integrating phono amplifiers into a complete preamplifier; differing phono amplifier technologies; covering active, passive, and semi-passive RIAA equalisation and transconductance RIAA stages; the tricky business of getting really accurate RIAA equalisation without spending a fortune on expensive components, such as switched-gain MM\/MC RIAA amplifiers that retain great accuracy at all gains, the effects of finite open-loop gain, cartridge-preamplifier interaction, and so on; noise and distortion in phono amplifiers, covering BJTs, FETs, and opamps as input devices, hybrid phono amplifiers, noise in balanced MM inputs, noise weighting, and cartridge load synthesis for ultimately low noise; archival and non-standard equalisation for 78s etc.; building phono amplifiers with discrete transistors; subsonic filtering, covering all-pole filters, elliptical filters, and suppression of subsonics by low-frequency crossfeed, including the unique Devinyliser concept; ultrasonic and scratch filtering, including a variety of variable-slope scratch filters; line output technology, including zero-impedance outputs, on level indication for optimal setup, and on specialised power supplies; and description of six practical projects which range from the simple to the highly sophisticated, but all give exceptional performance.  Electronics for Vinyl brings the welcome news that there is simply no need to spend huge sums of money to get performance that is within a hair’s breadth of the best theoretically obtainable.

This book continues the engaging prose style familiar to readers as you learn why mercury-filled cables are not a good idea, the pitfalls of plating gold on copper, and what quotes from Star Trek have to do with PCB design.   Learn how to:    make amplifiers with apparently impossibly low noise  design discrete circuitry that can handle enormous signals with vanishingly low distortion  transform the performance of low-cost opamps  build active filters with very low noise and distortion while saving money on expensive capacitors make incredibly accurate volume controls  make a huge variety of audio equalisers use load synthesis to make magnetic cartridge preamplifiers that have noise so low it is limited by basic physics sum, switch, clip, compress, and route audio signals  build simple but ultra-low noise power supplies be confident that phase perception is not an issue  Including all the crucial theories, but with minimal mathematics, Small Signal Audio Design is the must-have companion for anyone studying, researching, or working in audio engineering and audio electronics.","brand":"WoB","offers":[{"title":"- \/ - \/ -","offer_id":51459749904657,"sku":"","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ NEW \/ GARDNERS","offer_id":51459749970193,"sku":"NGR9781032366272","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/1032366273.jpg?v=1751367133"},{"product_id":"audio-power-amplifier-design-handbook-book-douglas-self-9780750656368","title":"Audio Power Amplifier Design Handbook","description":"Douglas Self has dedicated himself to demystifying amplifier design and establishing empirical design techniques based on electronic design principles and experimental data.
