Befaco's 1U ST AMP is a stereo preamplifier that brings external audio signals to the higher Eurorack level. The module in Intellijel 1U format uses the same pinout as the Intellijel cases(Palette 104, 7U Performance), making it fully compatible with the rear connectors of the Intelljel case. Other equipment like eg. TE Pocket Operator, Korg Volca or a smartphone can be connected to the 3.5mm stereo jack input. The gain is selectable in the factor Gain x1, x5 and x10 and can be finely levelled with the control; the signal output is in stereo.
