We recently saw how certain audio power amplifiers can be used as oscillators. This Design Idea shows how those same parts can be used for simple amplitude modulation, which is trickier than it might ...

In May 2025, Marantz introduced two reference-grade home theater components: the AV 20 preamplifier and processor and the AMP ...

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 ...

The circuit was designed to produce an audio power amplifier that operates in the range of Class A type while providing a power output of 40 Watts. Class A – refers to an output stage where the bias ...

As we’ve traced our no-nonsense path through the world of Hi-Fi audio, we’ve started with the listener, understood the limitations of the human ear, and thence proceeded to the loudspeaker. We’ve ...
