The Class D amplifier topology theoretically offers ideal characteristics for audio: 100% efficiency, 0% THD, and no audible noise. While practical Class D implementations can come attractively close ...
If you’ve ever glanced at the specifications sheet for an amplifier, one of the things you may have noticed is the amplifier’s class. Typically denoted by a letter or two, the most common amplifier ...
There are two salient facts about Class A amplifiers: they are inefficient; they give the best possible distortion performance. The quiescent dissipation of the classic Class A amplifier is equal to ...
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 ...
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 ...
