8 Channel passive mixer, also available as DIY project
RK-003
The new RK003 ‘Quickie board’ is pre-assembled and even smaller than the original by using SMD components. There’s a small 3D print enclosure model here as well on Google Drive
The RK-003 is a stereo (audio) mixer which you can use in your mobile setup.
Features are:
- No batteries (Passive mixer)
- Small Raspberry Pi Zero footprint
- DIY Kit (optional assembly)
‘Passive mixer’ means there is no built in amplifier and although there is volume drop on this system when you mix all channels together; We thought the fun factor is very high anyway.
Just crank up your amp a bit more and connect your Volca’s, Pocket Operators, Boutiques, Nintendo’s, iPhones,.. or any device you’d like to use to jam away.
