The only practical audio tests & measurements manual in English language! Learn how electronic test instruments work and how to measure AC & DC voltage, current, power, phase shift, resistance, capacitance, inductance, gain/attenuation, distortion, and other parameters of audio equipment. The operational principles, features, capabilities and limitations of multimeters, LCR meters, oscilloscopes, function generators, spectrum analyzers, LCR bridges, power supplies, transistor & tube testers, are explained in a simple and systematic way. Learn how to measure various parameters of hi-fi and guitar amplifiers, preamplifiers and crossovers, such as power consumption, gain, input sensitivity, output power, harmonic and intermodulation distortion, signal-to-noise ratio, crosstalk, input and output impedance, damping factor, frequency range and amplitude characteristic, AC & DC voltages and waveforms, phono stage equalization accuracy and even some speaker measurements. This large format (A4 size) manual is richly and professionally illustrated with more than 130 photographs and 250 illustrations, measurement setups, circuit diagrams, graphs and tables. Who will benefit from this unique and practical book?DIY constructors and amplifier builders who want to test the audio gear they've built and check its performance audiophiles interested in the technical side of audio and the testing aspect of hi-fi equipment guitar players who like modifying, repairing or building their own amps and speaker boxes electricians, electrical or instrumentation technicians with interest in audio measurements electronic engineers and electrical engineering students collectors, buyers and sellers of vintage test instruments, who want to learn about their operating principles and features CONTENTS (Chapter titles): TEST INSTRUMENTS, ERRORS, LIMITATIONS & SAFETY ISSUES SIGNAL SOURCES, TRACERS, POWER SUPPLIES AND FILTERS MULTIMETERS - TYPES, OPERATING PRINCIPLES AND FUNCTIONS OSCILLOSCOPES - HOW THEY WORK & HOW TO USE THEM TESTING PASSIVE ELECTRONIC COMPONENTS (RESISTORS, CAPACITORS & INDUCTORS) TESTING AUDIO AMPLIFIERS AND PREAMPLIFIERS DISTORTION MEASUREMENTS TRANSFORMER TESTS & MEASUREMENTS LOUDSPEAKER TESTS & MEASUREMENTS TRANSISTOR TESTERS AND CURVE TRACERS TESTING VACUUM TUBES (VALVES)
