Looking for help understanding setting up Universes.
Ok I'm a volunteer at our PAC which is a new high school(fall 2018) with 860 seating. We have 15 Pars above stage, CYC lights, 6 Mythos plus a number of Lekos on all 3 electrics & FOH. I understand how to patch into the different universes for each fixture. Plus we are currently patched into using 2 universes. But I am trying to understand what I think is the hardware side. our 1st & 2nd Electrics & the FOH(Catwalk) are on the 1st universe. The 3rd Electric & the 2 Mythos on the Catwalk((Data fed is via a wireless setup to the CAT) are on the 2nd Universe. Is each universe set up at the DMX Control unit & either hardwired in to the Electrics or Wireless sent? How would I go about adding a 3rd universe if we wish to do this so we can have more options with the total number of addresses we can use? Looking to educate myself on this topic so any help is awesome.
