“Utilizing the NE5532 operational amplifier, a voice level meter circuit assesses audio signals. The NE5532 is a widely used operational amplifier (op-amp), carefully designed for applications requiring excellent audio performance. This IC is frequently used in various audio equipment, including …
“A basic 4 channel mono audio mixer with gain amplifier and a 10 LED VU-meter BACKGROUND I am designing and building a series of Eurorack modules for interfacing modular analog synthesizers. As I am not a musician, I am …
“Band Pass filter is one which can pass only a specified band of frequencies. For example a band pass filter for woofers have the lower cutoff frequency as 200Hz and upper cutoff frequency as 2KHz, that is the mid range …
“Good afternoon, dear viewers and readers. In todays article, I will show you the universal microphone amplifier based on the microcircuit NE5532. The microphone amplifier schematic diagram and printed circuit board (PCB) were developed in Easy EDA online environment. The …
“In this project we will keep it simple when it comes to wireless audio communication. Instead of trying to use an nRF24 or RF modules, we will go back to the old days in which they used AM radios. I …
“I built a shortwave radio receiver from scratch using only cheap and easily available components, i.e. standard transistors, op-amps and 74xx logic chips. No typical radio parts – no coils, no variable capacitors, no exotic diodes. This project is easy …
“I’ve been building (and trying to perfect) the headphone amp for some time now. Some of you would have seen my previous ‘ible builds. For those that haven’t I have linked these below. On my older builds I …
“After discovering Cew27’sCmoy Headphone Amp a few months ago on Instructables, I’ve been inspired to build my own. I was also inspired by Koogars amazing Crystal CMoy Free Form Headphone Amplifier which I have been admiring for a …
