Doepfer A-138j Inverting/Interrupting Mixer (Janus Mixer)
- Order number: 220286
- Depth: 31
Mix, Attenuate, Invert, Offset, Mute - Doepfer’s 138j Inverting/Interrupting Mixer is a nice 4channel utility for all kinds of signals.
Each channel has a 3-way switch, that lets you decide whether to attenuate, invert or mute the incoming signal. Channel 1 can also deliver an Offset-voltage of +/-5V when nothing is plugged into the input. There are two Mix outputs - probably saving you a multiple or Stackcable. On Channel 1 and 2 there are also two outs each. When you use Out A, the signal is passed on to the Mix out. When using Out B, it gets removed.
The Module is DC-coupled, meaning it is suitable for all kinds of modular signals. With (just) 6HP it delivers a ton of applications, that is much needed in every rack.

WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
