The Intellijel Octalink 1U is a connection module for modular synthesizers in Eurorack format. The module is always used in pairs. It is used to connect up to eight control and audio signals between two separate Eurorack systems. The network port is connected to the eight sockets, so that each individual system can be pre-patched. All signals that are to be forwarded from one system to another, such as master clock, start, stop or master CV, are then connected via the Octalink 1U module pair with only one network cable. The Octalink 1U is compatible with the Doepfer A-180-9 multicore module.
