The Befaco 1U TRS is a combination of splitter and adapter for the 1U series of the . First, the module is connected to the pin headers of the socket pairs 1+2, 3+4 or 5+6, resulting in two or four usable connections depending on the cable and signal used. In addition, it can be selected per socket of the 1U TRS whether the connection is operated with line or Eurorack level. Since all three contacts (tip, ring, GND) of the large jack sockets of the case are used, there are different constellations when using TS, TRS or insert cables. If TS (mono) cables are used, two signals are available at the 1U TRS, which is available at both jacks. TRS and insert cables carry two signals each, resulting in four signals at the 1U TRS, which carry the signals of 2x ring and 2x tip.
