OK,I bought 4 Elation sixpar 100tm's. Very happy with their output and color. In addition,I am using PAR 38's with LED spot lamps for white lighting only.I am very happy with them too. 2 questions.I have an older controller,maybe 20 years old.Can that be used to control the new lights? Also,with my old controller or a new controller,can I use it for both the elations and the the PAR's . The new Elations of course can run the XLR right into the fixture.For the PAR's,I would need power packs which I have,Can one controller do both?
