The final amplifier is the power source of every audio installation. Its job is to convert a small alternating voltage into a powerful signal for driving loudspeakers with as little distortion as ...

1. Is Amplifier Weight an Indicator of Robust Amplifier Design? You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before you can generalize about weight ...

Love Class A amplification but hate the heat associated with it? The Infigo Audio Method 6 offers a very different take. There are many ways to eat your Smarties and Infigo Audio believes that it has ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...

If you already know about class A, B, and AB, they are all linear amplifiers with constant gain where the audio is fed to the base of a transistor. The latest class D audio amplifier is switch type ...
