I have a question on using a patchbay to transfer the signal from a line mixer to the front input on a preamp. In a rack, if I was to take the output from a line mixer and plug it into the back of the patchbay and run a cable out the front of the patchbay to the input on the preamp, would this work? I'm trying to avoid leaving an open space to run the cable to the front of the rack. I would also like to plug the basses into the front of the patchbay and run the bay to the line mixer so I don't have to plug in and out of the line mixer all the time. Sorry for the long post but patchbays kind've confuse me. Thanks for the time.
