The circuit below shows a 4-transistor utility amplifier suitable for a variety of projects including receivers, intercoms, microphones, telephone pick-up coils, and general audio monitoring. The ...

ThermalTrak integrates power output transistors with thermal bias diode. One of the major design concerns in the output section of a typical class AB audio amplifier is output bias and stability over ...

Peachtree Audio’s GaN400 stereo power amp ($3,000) blazes new trails for Class D amplification. The amp uses cutting-edge GaNFET transistors in its output stage, delivering a massive 400wpc! Read on.

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 ...

It may not be to everyone's taste, but this brand new monobloc amplifier from McIntosh cleverly blends both vacuum tube and solid-state technology in one chassis. If you’re not a serious audiophile ...

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 ...

A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...

The new 200W McIntosh MA352 Integrated Amplifier brings vacuum-tube technology and solid state components together in a unique hybrid design. Classic American audio brand McIntosh Labs – the brand ...

Different classes of amplifiers. What are the benefits of class AB amplifiers? Patents that address the quiescent current of class AB amps. Amplifiers have many classifications, and each class has its ...
