Learn how power amplifiers work, the common types, and what to lookout for when shopping for amps. You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before ...
Although Class A cost the most and are least practical, they are still preferred because the sound best, returns very clean signal, it is the most linear and has the lowest distortion. The circuit’s ...
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 ...
In market for a powerful 200 WPC amp? ATI has you covered with two completely different technologies. We compare the AT4000 class A/B and the AT522NC Class-D amplifiers to help you decide. EIA 1kHz ...
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 ...
Love Class A amplification but hate the heat associated with it? The Infigo Audio Method 6 offers a very different take. There are many ways to eat your Smarties and Infigo Audio believes that it has ...
Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more ...
A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...
Launched at CES 2005, a direct digital feedback technology from audio switching amplifier specialist Zetex Semiconductors sets new standards in digital amplifier sound quality. Named Class Z, this ...
