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 ...

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, ...

As Axiom’s chief R&D engineer Tom Cumberland describes it, a digital amplifier is a “power DAC”, and of course a DAC (Digital-to-Analog Converter) is the basis of all digitally recorded media, whether ...

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 ...

We talk to Lenbrook's Chief Technical Officer, Greg Stidsen, to find out about his hi-fi journey and what the future holds ...

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 ...

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 Cherry Audio MEGAschino Mk2 Standard Edition Class D Amplifier is energy efficient, boasting SOTA specs and gobs of power output (>400wpc, 8 ohms). Is it worth the $6k price? Read our review. The ...

Nuvoton has released the NAU83U25YG, an automotive-grade Class-D audio amplifier designed for vehicle electronics ...

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 ...
