You have to get the sound into the box somehow.

In one space we have a couple interfaces connected to one of these

This way we can connect various equipment to the interfaces without stressing the connections on the device itself. We damaged a line in on a 1010 interface once which was a touchy repair, so decided to leave them hooked to this patchbay and connect whatever we need that way.
Generally we just use it as a through..


I do not work here, but the benefits are still awesome
