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, ...

The active components of the Class D amplifier are the switching output stage and modulator. This circuitry can be built for roughly the same cost as an analog linear amplifier. The real trade-offs ...

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 ...

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 ...

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 ...

Emitted EMI is a drawback to the switching topology of the Class D amplifier. Passive filtering can moderate EMI but adds cost and complexity to the end product. What other internal circuit design ...

The Mola Mola Ossetra is a $25,100 Class D mono amplifier delivering 350W into 8 ohms with ultra-low distortion, challenging ...

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 ...

Older generations of class D amplifiers had high enough distortion for this problem to go unnoticed, but the native performance of the 1ET400A is so good that any distortion caused by wiring sticks ...

When people think of the Yamaha brand, they likely think of one of two companies. There's the Yamaha Motor Company, which is responsible for various modes of transportation, including some powerful, ...

Cambridge Audio’s Evo 150 is a beautiful, “just add speakers” streaming amplifier designed for modern audiophiles who prefer not to deal with a traditional component rack. It was originally released ...
