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 amplification is becoming the solution of choice in consumer audio, by enabling long battery life and compact dimensions. However, designers must take care to avoid complexity elsewhere ...

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 ...

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 ...

This article was originally published in the Dec 14, 1998 issue of Electronic Design. Class-D audio power amplifiers (APAs) were first introduced nearly 50 years ago. Since then, they have been used ...

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, ...

The Extron XPR Ultra Amplifiers utilize proprietary Class D technologies. Diversifying its product line, the new Extron XPA Ultra Amplifiers offer professionals integrators more channels of ...

Starke Sound’s new AD4.320 4-channel power amplifier ($1,399) uses a home-grown Class D amplifier module combined with an old-school linear power supply. It can be bridged for up to 650 watts!

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 ...
