[Alan’s] friend came to him with a problem. He loved listening to his scanner, but hated the volume differences between stations. Some transmitters would be very low volume, others would nearly blow ...

A microphone preamp circuit is used to amplify a microphone’s output signal to match the input level of the devices following it in the signal chain. Matching the peaks of the microphone’s signal ...

This audio amplifier circuit is useful in classrooms to reduce the strain of lecturing ,if the surrounding environment is noisy. It uses the power amplifier IC LM380 that gives 2 watts output which is ...

ok, so im just fooling around with audio circuit related stuff trying to learn new stuff, and I have some questions.<BR><BR>I am making a Bandpass filter with peak ...

“Phantom powering” is the most common way to power a microphone. The technique supplies 48 V provided through two 6.81-kΩ resistors in a differential input line. 1 This idea explains an improved way ...

One big factor in avoiding the pickup of power line hum in audio circuits is to keep audio cables away from any power lines, cables or circuits (most notably power transformers). Use good cable ...

The field of wave digital modeling has emerged as a robust framework for simulating nonlinear audio circuits with high fidelity, bridging the gap between analogue intricacies and digital efficiency.
