This is a uniquely detailed guide to the theory and practice of audio power amplifiers, running from the elegantly simple mathematics of the differential pair to the practicalities of bolting down power transistors properly. It includes the first complete explanation of the complex business of power amplifier distortion. It shows how the many sources of non-linearity can be eliminated or minimised, allowing amplifiers to be designed and constructed with performance that would have been thought impossible a few years ago. It provides information that is indispensable whether you are making one amplifier for the ultimate home system, or setting up a production line to make 10,000 units a year. THE CONTENTS INCLUDE: New Findings in amplifier design Science & Subjectivism The Performance Requirements A Short History of Amplifier Design How Negative Feedback really works The Eight distortion mechanisms Diagnosis via distortion residuals The input stage: how it can cancel distortion The Voltage-Amplifier Stage Output stages Amplifiers and reactive loads Anomalous loudspeaker behaviour Interchannel crosstalk Compensation, Slew-Rate, and Stability Power Supplies and PSRR Class-A amplifiers, with a design example Class-G amplifiers FET output stages: why they are a bad idea Load Invariant Power Amplifiers Thermal compensation and thermal dynamics Amplifier and Loudspeaker protection Grounding systems Mechanical design constraints Testing, Fault-finding and safety requirements NEW MATERIAL IN THE FIFTH EDITION: Completely new chapter on the Class-XD Crossover-Displacement principle as used by Cambridge Audio Big new section on double input stages A big new section on power transistors with internal sensing diodes Big new section on input stage common-mode distortion More on: Four-stage amplifier architectures Amplifier bridging Amplifier stability Advanced line input stages Ultra-low-noise design Current-mirrors Better DC servo design Output stages with gain Inrush current suppression Transformers and hum fields The subtleties of cooling fan control Thermal protection DC offset protection Infra-red control Signal activation 12V trigger activation Professional power amplifiers The latest safety regulations and requirements ... and much more
