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 ...

Trade offs in designing with IC and discrete component class D amplifiers including switching speeds, filtering options, and power supply considerations. The switching amplifier, or class D amplifier, ...

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 ...

High-fidelity sound reproduction enthusiasts are the latest beneficiaries of Gallium Nitride (GaN)’sfundamental qualities, as it provided these audiophiles respite in their challenging environment.

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 ...
