We just got 15 LED Par's for our "Little Theatre" and to my dismay, they have 3-pin (is it still called DMX?) "control" inputs and outputs. I'm planning to control these off of a Leprecon LP-624 which has a 5-pin DMX port in addition to a 3-pin Microplex port. Can i control these LED's with the Microplex? If not, how would you advise controlling them from the 5-pin DMX port.To make this more complicated, I also have 4 Altman 6" Fresnels that I need to control off of the same board. Should I invest in a DMX splitter or not? What are my options? All help is appreciated. Thanks!!
