I anticipate having to install a new sound system in a building that previously had a sound system, which has been stripped out. I anticipate about a dozen XLR microphone connections at one end of a large seating area, with the audio board at the other end. There is presently a steel conduit in place for the mic cables. What I would hope to do is run three "Cat5" cables thru the conduit , along with a single "ground" wire, thru the conduitto a junction block in a steel junction box at each end of the conduit. From that box on would be standard 2 conductor plus shield cables to each XLR jack. On the audio board end a similar arrangement. The single ground wire will connect with all the shields at each end, and serve as the other side of the phantom power circuit. Has anybody done something like this? Does anybody see any problems?
The motivation is cost. Mic cable is not cheap, while cat 5 cable costs a lot less as it is tending toward obsolete. And probably even cat4 cable is available and will still be OK at audio frequencies.
