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.

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 ...

Class D is a digital-like amplifier that works by turning a transistor fully on or off, but the "D" technically does not stand for digital. See Class D amplifier.

If you didn’t know better, you might think the phrase “class A amplifier” was a marketing term to help sell amplifiers. But it is, of course, actually a technical description of a… ...

Because they are extremely inefficient. Most amps are class A,B, or A/B which iirc only output something like 30% of the power they use to the speakers. Class D and T? are much much more efficient ...

Apogee Technology has complained about some of Texas Instruments Inc.'s Class D claims. In March, TI called itself the first to introduce a single-chip Class D amplifier in the 125-watt/channel range.

Ironically, you'd actually come out ahead using tubes. An 80W stereo class A amp is going to suck a <B>minimum</B> of 500W - all the time it's on.

The current dumping amplifier is one that combines a small class A amplifier with a hefty class B one, and through feedback trickery uses the combination to remove the crossover distortion of the ...

The Si270x amplifier is ideal for use in a wide range of price- and noise-sensitive consumer audio products including smart phone docking stations, tabletop radios, TV sound bars and monitors, boom ...

The audio amplifier market is progressively growing while advances in semiconductor technology enable more applications to use class D amplifiers. But are metal-oxide-semiconductor ...
