Mini Passive Mixer

thingiverse

Mini audio mixer with 2 stereo inputs, 1 mono input, and 1 stereo output. 3.5mm jacks are included. Plans and more details can be found at http://therandomlab.blogspot.com/2015/05/simple-passive-monostereo-to-stereo.html. This particular model does not match the original schematic exactly, as it features two stereo channels and one mono channel merged into a single stereo output. A 10K potentiometer, 1K resistors, and 1uF capacitors were used in its construction. The 3.5mm sockets utilized are "5-Pack CESS 3.5mm Stereo Balanced TRS Socket Female Connector Panel Chassis Mount (#318: 3.5mm Stereo Socket,5-Pack)" from Amazon. M3 screws were employed to secure the lid in place.
