4-channel stereo mixer in 28HP 1U Intellijel format. Pairs as Hexmix submix expander.

28 HP Eurorack module

STMix 1U is the 1U sibling of Befaco's STMix 3U module — a compact four-channel stereo mixer in the 28 HP Intellijel 1U format. Each channel has L and R inputs and a single attenuator knob. Every channel supports mono operation by simply patching L only — the L signal is internally duplicated to R, placing the source in the center of the stereo mix. All inputs are AC-coupled for audio fidelity. STMix can run standalone or chain via its rear 6-pin connector (X2) into a Hexmix to expand its submix.
