Some kind of continuity beeper has been a standard piece of gear since the dawn of electronics. Sure, you probably have an ...

THE properties of the amplifier to be described are entirely due to the type of transistor used, and the purpose of this communication is to report on its suitability for the amplification of ...

Here is a pedal to heat up the relationship between your electric guitar and amp by applying some vintage tone sweetening mojo to the front end. It is called the WEM CCB-1 Copicat, and it is as preamp ...

With fully balanced and improved circuitry throughout, the BAT VK-85 Preamp and REX 300 Amp claim pure musicality from a $27,500 combo. The REX 300 is a lower-powered version of the highly regarded ...

We may receive a commission on purchases made from links. High-end microphones are wildly expensive. As of this writing, there are used U47s on Reverb for over $20,000. But parts are affordable if you ...

Members can download this article in PDF format. In designing an input stage for an analog-to-digital converter (ADC), engineers choose a particular amplifier, assign a target gain, and note the ...

In a signal-conditioning op-amp application, is there an optimum circuit topology for optimizing SNR and SFDR? Here’s a succinct analysis, part mathematical, part simulation, and part cookbook, from ...

The circuit in Figure 1 is suited for inductive sources such as a dynamic microphone, transformer or inductance sensor/pick up. Figure 1 A simple amplifier circuit suited for inductive sources such as ...

The Anthem STR preamp and power amplifier emphasize fidelity first armed with the latest in 32 bit DSP, ARC room correction, and oodles of power reserves on tap. More details in our review so read on.

In Seemingly Simple Circuits: Transresistance Amplifier, Part 1– Approximating Op-Amps, the op-amp was approximated from a single-pole, finite gain amplifier to an infinite-gain, single-pole op-amp, ...
