It is a bidirectional module meaning the inputs can be outputs and vice versa.
It has two main uses depending on the direc- tion you are using the module.

– When using Réseaux with one input and multiple outputs you have attenuated copies of the input. Great to send a signal around. Specially if you have modules which do not have attenuators built in.

– When using one output and multiple inputs you have a mixer with set levels. It can mix both CVs and audio signals.
