Compact four-channel stereo submixer for Eurorack
6 HP Eurorack module
STMix is a compact four-channel stereo mixer in 6HP, designed for mixing stereo or mono signals in a Eurorack system. It features DC-coupled inputs for mixing CV as well as audio, an unattenuated Aux stereo input, and can expand the Befaco Hexmix module via a six-pin ribbon connector on the back.
