Class D amps are simple – just take an input, and use that to modulate a square wave with PWM. Send this PWM signal to a MOSFET or something, and you have the simplest class D amp in existence.

With active subwoofers demanding typical power levels up to 500W, building the amplifiers to meet the requirement is not without difficulty. Consider using a 50% efficient Class AB amplifier, and it’s ...

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...

I've been hosting an outdoor movie event for over 10 years now and have been slowly adding and upgrading equipment. There are usually around 30 people, pretty spread out and up to 50ft away from the ...

A new book authored by Robert N. Buono delves deeply into Class-D amplifiers, a crucial technology in audio designs. Buono has more than four decades of experience in analog and power electronic ...

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. EIA 1kHz ...
