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, ...

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 ...

Integration of audio into portable devices such as cellphones, DVD players, laptop computer and gaming devices has increased to the point where designers are faced with squeezing more and more ...

NAD launched two Masters Series amps, the M33 and M28 both priced at $4,999. Both amps offer performance that sets a new benchmark for low noise and distortion thanks to a revolutionary Class D design ...

Apogee Technology has complained about some of Texas Instruments Inc.'s Class D claims. In March, TI called itself the first to introduce a single-chip Class D amplifier in the 125-watt/channel range.

Linear audio amplifiers can provide excellent sound fidelity, but they consume a great deal of power and present significant thermal management challenges, especially in automotive audio systems.

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 ...

Fig 1. This shows the spectra of both waveforms when the Class D output is issuing silence (no audio, duty cycle = 50%) with a switching frequency of 333 kHz. Fig 2. The blue line shows the energy ...

Savant Systems LLC, having delivered the first Apple-based home automation and control system, has announced the introduction of a 16-channel class D amplifier for distributed audio applications.

Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more ...

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 ...
