A Quick Glance at Some Audio Amplifiers

Audio amps are the crucial element for connecting passive speakers to a source. Without an amplifier, loudspeakers would be unable to reproduce music. There many different types of amplifiers out there. It is hard to keep track of amplifier technologies. However, I am going to summarize some important technologies and also introduce some models of amplifiers which utilize these technologies.

Nowadays the market is dominated by digital amplifiers. These amplifiers also referred to as switch mode amplifiers. What makes these amplifiers different from analog amplifiers is the fact that the audio signal is generated through a switching stage rather than an analog output stage. This stage essentially switches the output voltage between the supply voltage and ground a high-frequency. The output signal is generated by modulation of the switching signal of this stage. Obviously, speakers …
