A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

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 ...

The efficiency and size advantages of Class D audio amplification in battery- powered devices are well known. These advantages are now extended to amplifiers up to 500W, made possible by solidstate ...

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.

Hang around in any of the many guitar or audiophile forums or discussion boards for long enough, and eventually you’ll come across the arguments over amplifier topologies. One of the more interesting ...

Because pulse modulation output signals are either on or off, Class D amplifiers produce far less heat than analog amplifiers. Reaching efficiencies greater than 90% compared to only 50% for analog, ...

Velodyne has introduced the SC-600D amplifier, an improved version of the SC-600. The SC-600D features a Class D amplifier – the original SC-600 featured a Class A/B design – which improves efficiency ...
