Send this PWM signal to a MOSFET or something, and you have the simplest class D amp in existence. They’re so simple, you can buy a class D amp chip for $3, but [George] thought that would be ...

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 ...

1 ohm stable D class monoblock amplifier; 2900 watt mono block true rms power. Low level input and output; Frequency response 20Hz to 350Hz. Variable subsonic filter, variable low pass filter ...

An enhancement of the Class G amplifier in which the power supply voltage is modulated and always slightly higher than the input signal. Class D is a digital-like amplifier that works by turning a ...

Design engineers can evaluate operating efficiencies of audio amplifiers while using standard benchtop measurement systems.

Universal IEMs with 13 drivers? FiiO’s FX17 integrates electrostatic and dynamic drivers, and balanced armatures in a ...

Wiim has launched the Vibelink Amp, a 100-watt-per-channel power amp that plays nice with digital music streamers and analog sources alike.
