I am working to upgrage a gradeschool theatre (K-8) from lights on/lights off circuit breaker control to something with dimmers. Since this is a parish school (read "no money"), and I'm strictly volunteer,it's a labor of love. Anyway, I eBay'd a couple of CD-80 12x2400 watt dimmer packs - that alledgedly work. I have cleaned them up on the inside and out and I would like to test them out to see what I've got before I hook them up in a more permanent installation. Unfortunately, they speak AMX and I'm having trouble even finding an AMX board to rent for a test. Is there any way to test the dimmers and interface without a controller? Second, assuming the dimmer packs work and I save my pennies for a DMX controller would I be better off going with an external DMX>AMX converter or biting the bullet and replacing the internals with either a new Strand DMX interface or the Johnson Systems retrofit? Any and all suggestions are welcome. Thanks in advance.
