Have you ever read an amplifier review and encountered the terms Class A, Class A/B or Class D? We explain all.

The goal of audio amplifiers is to reproduce input audio signals at sound-producing output elements, with desired volume and power levels–faithfully, efficiently and at low distortion. Class D amps ...

Figure 2: Class D open-loop-amplifier block diagram. Since most audio signals are not pulse trains, a modulator must be included to convert the audio input into pulses. The frequency content of the ...

Dedicated Class D IC drivers for medium-power audio amplifiers enable efficiencies three or more times greater than Class AB, and they reduce power loss by an order of magnitude or more per channel.

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… ...

The benefits of using Class D amplifiers. What to look for when choosing a Class D amp. Making the tradeoff between THD+N and quiescent current. Back in the day (1970s), audio amplifiers like the ...

The big advantage with Class D amplifiers is that they're much more efficient from an energy usage point of view than conventional Class AB amplifiers, which are what you've seen in most audio ...

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 ...

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 ...

Musical Fidelity’s new B1xi integrated amp ditches streaming for pure Class A/B power, a quality phono stage, and hi-res digital inputs for $879.
