Modules A-180-2 is a simple multi-connectors. It has eight inter-connected sockets, so that you can "multiply" any audio or control signal. From the factory the module comes as two four-fold multiples. But it can be modified as an eight-fold multiple (solder bridge on the pcb). Though the module is very "primitive" it is 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.

For the distribution of control voltages used for pitch control of several VCOs the buffered multiple A-185-2 is recommended. This module has a built in buffer (and a lot of additional features like CV summing) that avoids small voltage losses that may be heard in pitch control applications.
