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.
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 ...
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 ...
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 ...
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 ...
Each speaker comes in multiple "ready-to-experience" finishes and there are also extensive customization options. The standard options are Walnut Harmony, Oak Essence, Black Gold and White Aura. There ...
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 ...
Analog Devices has created a pair of 22V stereo Class-D audio amplifier that idle at 6mA and shut-down to microamps. MAX98415A and MAX98425A are similar, and both including envelope tracking control ...
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 ...
Can these two extra cool amps--the Bel Canto REF500S ($2,495) and the Dayton DTA-100 ($100)--offer green power for audiophiles? Ex-movie theater projectionist Steve Guttenberg has also worked as a ...
