Doepfer A-180-2 Vintage Edition with a black faceplate and custom knobs.
Modules A-180-1 and A-180-2 are simple multi-connectors. They have eight inter-connected sockets, so that you can “multiply” any audio or control signal.
From the factory the modules come as two four-fold multiples. But they can be modified as an eight-fold multiple (solder bridge on the pcb).
Though these modules are very “primitive” they are required very often in patches (e.g. to distribute a clock signal or a control voltage).
Within a big A-100 system sufficient multiples should be planned. The function of A-180-1 and A-180-2 is the same. The modules differ only in the front panel width.
