Summary

[edit]
Description

I was recently comparing several powered speaker systems, but didn’t like the audible *Pop* I heard when plugging and unplugging the 3.5mm headphone jack into each of them. I made a switchbox that eliminates this pop by switching the one input (my mobile phone) to any of the four outputs. This one has stereo logarithmic-taper potentiometers wired as voltage dividers, effectively acting as independent volume knobs on each channel.
