The economic importance of audio amplifiers. There are no practical textbooks. Knowledge assumed. Origins and aims. The study of amplifier design. analyzer and many purpose-built pieces of audio gear. He has published numerous articles and papers on power amplifier design and distortion measurement. High Efficiency Audio Power Amplifiers; design and practical use. Author: By substituting this PDF in Equation and , the dissipation for audio signals.
The negative feedback into the difference amplifier allows the amplifier to compare the input to the actual output. Focal Press can help. Electronic components. Other amplifiers may be classified by their function or output characteristics. Capacitor Distortion.
In high-powered audio applications that require long cables to the load e. This avoids long runs of heavy speaker cables. To prevent instability or overheating requires care to ensure solid state amplifiers are adequately loaded.
Most have a rated minimum load impedance. All amplifiers generate heat through electrical losses. The amplifier must dissipate this heat via convection or forced air cooling. Heat can damage or reduce electronic component service life.
Designers and installers must also consider heating effects on adjacent equipment. Different power supply types result in many different methods of bias. Bias is a technique by which active devices are set to operate in a particular region, or by which the DC component of the output signal is set to the midpoint between the maximum voltages available from the power supply.
Most amplifiers use several devices at each stage; they are typically matched in specifications except for polarity. Matched inverted polarity devices are called complementary pairs.
Class-A amplifiers generally use only one device, unless the power supply is set to provide both positive and negative voltages, in which case a dual device symmetrical design may be used. Class-C amplifiers, by definition, use a single polarity supply. Amplifiers often have multiple stages in cascade to increase gain.
Each stage of these designs may be a different type of amp to suit the needs of that stage. For instance, the first stage might be a class-A stage, feeding a class-AB push—pull second stage, which then drives a class-G final output stage, taking advantage of the strengths of each type, while minimizing their weaknesses.
