The Class B circuit has inferior sound quality, however, due to nonlinear behavior (crossover distortion) when the output current passes through zero and the transistors are changing between the on and off conditions.Class AB, a hybrid compromise of Classes A and B, uses some dc bias current...
The Crest Audio CD3000 is a Class-D amplifier capable of delivering 1500 watts per channel into a 2Ohm load. Amazingly for such a brute, the CD3000 only takes up 2U of rack space, and weighs a mere (for a power amp) 21kg.Here's a good question: just why are power amplifiers so ...
Most power amplifiers used in audio systems are of the A, B or AB classes. Class A amplifiers are distinguished for having very low levels of distortion. A class B amp usually costs less than a class A amp and generally is more efficient in overall operation. The quality of the output ...

As a freshman in high school, I managed to select an almost impossibly horrible schedule of classes that led me on an epic walk across the full length of our sprawling campus not once but twice each day. I was 14, and September and October were shitty and cold, as they usually are at...

三、Different Classes of RF Power Amplifiers RF power amplifiers are classified based on the operating principle and waveform of the amplifier's output signal. The most commonly used classes are Class A, Class ...
