The literature on power amplifiers frequently discusses the importance of power-supply rejection in audio amplifiers, particularly in reference to its possible effects on distortion [4]! I have (I ...

However much care is taken, it is very difficult to keep all traces of transformer-induced hum out of the signal circuitry. It is highly irritating to find that despite the cunning use of low-noise ...

The efficiency and size advantages of Class D audio amplification in battery- powered devices are well known. These advantages are now extended to amplifiers up to 500W, made possible by solidstate ...

We’ve analyzed inputs, signal processing, and clocks and used the analysis to put together a workable soundbar design (see http://electronicdesign.com/author/36602 ...

2x 500W in 2 Ohm BTL at 50V or in 4 Ohm BTL at 70V, with 97% efficiency 1x 1000W in 1 Ohm PBTL at 50V or in 2 Ohm PBTL at 70V, with 98% efficiency Less than 3W of total idle losses for the GaN power ...

We have had the good fortune of testing some of the industry's best multi-channel amplifiers. If you are from the camp that all amps sound the same, then don't waste your time reading another ...

H x W x D (inches) = 4 x 18 x 17.5 Technological progress is a wonderful thing. Over the past 40 years or so, we’ve seen computers that filled an entire room get eclipsed in processing power by ones ...

Marantz has unveiled two products that showcase its new industrial design language: the Marantz Model 30 integrated amp and the SACD 30n network audio streamer and SACD player. This new look ...
