A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

This article started because a good friend of mine dropped a Panasonic SA-XR50 switch-mode amplifier to me for some basic bench test. This article will NOT be a review of that unit, but an ...

Understand the basic audio components of a Hi-Fi stereo system so you know what to look for when shopping for audiophile equipment. Amplifier. Amp. Preamp. Integrated amp. Phono stage. Tube amplifier.

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 ...

You could argue that the integrated amplifier is arguably the most critical component in modern hi-fi. It combines a power amplifier, a built-in phono preamplifier (which you need to connect a ...

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...
