The Yamaha C-5000/M-5000 pairing is an impressive, well-engineered performer ...

What every RF design engineer needs these days is a good all-purpose IC RF amplifier. You don’t want to have to design basic circuits like this yourself. Yet the need is always there for a gain block ...

The most common device for the measurement of load, pressure, torque, and even piezo-resistive (low frequency) acceleration is the strain gauge transducer. As a transducer, which converts a measured ...

Missions to space require "warm" boxes, which protect electronic circuitry from extreme temperatures and exposure to radiation. Electrical engineering researchers have now designed and successfully ...

Op-amps are among the most widely used electronic devices, and are designed into many consumer, industrial, and scientific devices. General purpose, standard op amps sell for well under one dollar.

Semiconductor companies have now had fully-differential amplifiers in their product lines for a few years, though these amplifiers have been in leading-edge electronics for decades. These diff-amps ...

At $4,320, the Chord Alto is a compact desktop amplifier that powers up to four headphones, a pair of speakers, and also functions as a preamplifier with active studio monitors. Based in the UK, Chord ...

A little over a year ago Chord Electronics announced its most accomplished amplifier technology yet, Ultima. It launched in a mono design but is, from today, available in a stereo configuration, with ...

Ex-movie theater projectionist Steve Guttenberg has also worked as a high-end audio salesman, and as a record producer. Steve reviewed audio products for CNET and worked as a freelance writer for ...
