Two S16's, Two X32's, one P16D, eight P16M.
S16-->S16-->X32 FOH-->X32 Record, using generic Cat5e UTP (install, through conduit). Roughly 100-150' runs. Also, X32 FOH-->P16D-->8X P16M, also generic C5eUTP. Add patch cables at FOH and the P16's (connected via Neutrik NE8FDP's).
No problems. Though figuring out how to get returns from Record to FOH took a bit of thinking.
