A new amplifier has been created by KJF audio and Stefan Whatcott specifically for those who require 2 to 8 audio channels at affordable prices. “A Flexible project aimed at audio and cinema-philes, ...

Cambridge Audio is launching the Evo 150 SE, a special edition of its Evo 150 streaming amplifier. As part of a partnership with Hypex, Cambridge Audio has developed the NCOREx “Tuned by Cambridge” ...

I've done an extremely irresponsible thing. In the journey towards my "endgame" audio setup, there is now a custom-built Hypex NC502MP-based amplifier on order. It has the ability to send an obscene ...

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 ...

A class-D puts out a pulse-width modulated (PWM) signal instead of the linear signal that is typical in class-AB amplifiers. The PWM signal contains the audio signal and the PWM switching frequency ...

Most audiophiles and enthusiasts have grown up with at least a basic understanding of what an amplifier does. It takes a tiny alternating electrical signal that represents the moment-to-moment ...

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...

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.

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 ...
