One of my first jobs as an engineer was at Empire Scientific Corp. in Garden City, NY in 1972. This was a high-end audio company that made speakers, turntables and phonograph cartridges. We had some ...

As nearly all audio amplifiers have transitioned from linear or near-linear operating modes (Class A, AB, and B) to digital (Class D), it may seem that the only areas for improvement are in power ...

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 ...

Does the Peachtree Audio GaN400 power amplifier redefine Class D? Let’s take a deeper look at this new amplifier that offers over 400 watts per channel. Peachtree Audio are a very interesting company.

Class D amps from $130 to $50,000—pulling more ears into hi-fi without demanding you sell a kidney. Solid tech, serious power, and none of the usual overpriced fluff. Finally, affordable doesn’t sound ...

Linear audio amplifiers can provide excellent sound fidelity, but they consume a great deal of power and present significant thermal management challenges, especially in automotive audio systems.

Ex-movie theater projectionist Steve Guttenberg has also worked as a high-end audio salesman, and as a record producer. Steve reviewed audio products for CNET and worked as a freelance writer for ...

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 ...

Cambridge Audio — the British audio manufacturer best known for its beautiful, high-end and new-age streamers, amplifiers and turntables — has announced a compact power amplifier for traditional hi-fi ...

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 ...
