“This is a crossfader circuit. It accepts two inputs and fades between them, with the output being a mix of the two inputs (or just one of the inputs). It’s a simple circuit, very useful, and easy to build! It does invert the signal going through it, so you won’t be able to use it for control voltages.
Supplies:
Here’s what you’ll need:
1 potentiometer, 20K will work best, but you can get away with anything from 5K to 100K
4 10K resistors
1 20K resistor
1 100nF ceramic disc capacitor
1 TL074 quad op amp
Various wires for power and stuff
Pliers to bend stuff
Clippers to cut wires
A soldering iron and solder
A desire to become a soldering ni”
