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 ...

The Class D amplifier topology theoretically offers ideal characteristics for audio: 100% efficiency, 0% THD, and no audible noise. While practical Class D implementations can come attractively close ...

StormAudio has introduced a multichannel amplifier reinforcing the shift toward networked, software-driven AV system design ...

Pure Resonance Audio has released its latest product, the DA2500 500W two-channel rack mount power amplifier. Designed with unique dual-impedance operation, this Class-D amplifier is set to ...

EPC has used GaN transistors to create a high-power Class-D two-channel audio power amplifier design. Instantiated in evaluation kit EPC9192, it is capable of pushing 700W/channel into 4Ω (or 2Ω) or ...

Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...

NXP Semiconductors N.V. has enhanced its family of Class-AB audio amplifiers, providing improved quiescent current reduction and decreased smart phone signal interference. The integrated GSM input ...

Cambridge Audio — the British audio manufacturer best known for its beautiful, high-end and new-age streamers, amplifiers and turntables — has announced a compact power amplifier for traditional hi-fi ...

Join [Jørgen Kragh Jakobsen], Analog/digital Design Engineer at Merus-Audio, for this week’s Hack Chat. Every week, we find a few interesting people making the things that make the things that make ...

1. Is Amplifier Weight an Indicator of Robust Amplifier Design? You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before you can generalize about weight ...

Burson’s Soloist Stellar is a $1,500 Class-A headphone amplifier delivering up to 8W of power, a dedicated low-noise IEM stage, and upgradeable op-amps for demanding headphones and sensitive wired ...
