The final amplifier is the power source of every audio installation. Its job is to convert a small alternating voltage into a powerful signal for driving loudspeakers with as little distortion as ...

Krell announced the most revolutionary design change in its 33-year history: iBias, a patent-pending new technology that uses the Class A circuitry preferred by audiophiles yet consumes far less ...

If you didn’t know better, you might think the phrase “class A amplifier” was a marketing term to help sell amplifiers. But it is, of course, actually a technical description of an amplifier that ...

In March 1985, I was reading a copy of my favorite hi-fi magazine. It carried a story about a brand-new British amplifier from Musical Fidelity. The reviews for the A1 amplifier were glowing, as was ...

Krell announced their new iBias technology at CES 2014 to be integrated into their amplifier line. Many audiophiles (and people that care about sound if you feel "audiophile" is a dirty word) believe ...

The design of the circuit is based on the operation of a class A amplifier for the purpose of driving a pair of headphones using a mini amplifier. The design of the circuit is based on the operation ...

At first look the Parasound Halo A 21 and A 51 are appealing and robust amplifiers accented by brushed metal finish and a "Halo" aqua blue light around the power button. But an amplifier is not just ...

“Class” is in session. This discussion of electronic amplifier circuits offers an overview of the characteristics that define commonly used class designations ...

A little of the old, a little of the new—here's a quick brushup on amplifier lore. Amplifiers are fundamental circuit-design elements. They drive everything from earbuds to antennas. Placed ahead of ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...
