From the project
Stereo audio balance indicator with KiCad source and PCB manufacturing files.
A stereo audio balance indicator that compares the relative signal levels of the left and right channels and provides a visual LED indication of channel imbalance.
The project was developed as a junior-year analog electronics project and includes the KiCad design source together with PCB manufacturing artifacts.
- Stereo left/right level comparison - LED-based visual indication - Adjustable response through potentiometers - Analog signal-processing design - KiCad schematic source - Gerber manufacturing package
