A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...

Class D audio amplifiers have been increasingly famous in the recent years. This article will present the what’s, why’s and how’s of Class-D audio amplifiers. The article will also present audio ...

Hang around in any of the many guitar or audiophile forums or discussion boards for long enough, and eventually you’ll come across the arguments over amplifier topologies. One of the more interesting ...

Class-D audio amplifiers represent a significant advancement in modern audio engineering by utilising high-frequency pulse modulation to drive output stages with exceptional efficiency. Unlike ...

As Axiom’s chief R&D engineer Tom Cumberland describes it, a digital amplifier is a “power DAC”, and of course a DAC (Digital-to-Analog Converter) is the basis of all digitally recorded media, whether ...

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

Decades of development and high-volume production generated mature amplifier technologies that satisfy the requirements of many market segments. Class A designs address more demanding high-end ...

Because pulse modulation output signals are either on or off, Class D amplifiers produce far less heat than analog amplifiers. Reaching efficiencies greater than 90% compared to only 50% for analog, ...

Class D amps are simple – just take an input, and use that to modulate a square wave with PWM. Send this PWM signal to a MOSFET or something, and you have the simplest class D amp in existence.

Firstly I'd like to point out that "digital amps" is a misnomer. There are two categories: Analog-controlled class D. Switching amplifiers with an analog input signal ...

Class D amplifiers run cool to the touch, but they haven't always sounded great. Now they're gaining favor with audiophiles. Ex-movie theater projectionist Steve Guttenberg has also worked as a ...
