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 ...

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 ...

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 ...

The active components of the Class D amplifier are the switching output stage and modulator. This circuitry can be built for roughly the same cost as an analog linear amplifier. The real trade-offs ...

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 new generation of digital-input Class D audio amplifiers achieves high PSRR performance that is comparable to traditional analog Class D amplifiers. More importantly, digital-input Class D ...

Class D amplifiers are revolutionizing the audiophile world, delivering top-tier sound without the hefty price tag. Discover how brands like NAD, Topping, and SMSL are making high-quality audio ...

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.

This file type includes high resolution graphics and schematics when applicable. Class D audio amplifiers are able to fulfill the requirements for audio applications such as mobile handsets, Bluetooth ...

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 ...

Fig 1. This shows the spectra of both waveforms when the Class D output is issuing silence (no audio, duty cycle = 50%) with a switching frequency of 333 kHz. Fig 2. The blue line shows the energy ...
