Hey guys, I need some advice. In our Auditorium, we have two duplex outlets in our control booth that are being fed from our dimmer rack via a constant module. The dimmer rack also houses all the dimmers for the stage and house lights. I personally do not feel that this is a good idea because SCR dimmers put noise and harmonics on the lines, correct? We are going to be getting a full sound system put in during January 2009, and I don't think the new equipment should be powered from these outlets because of the harmonics and voltage flucuations. Also, couldn't noise enter our sound system because of this as well? The Power supply is 480 volt 3 phase before our transformer, then comes out as 208Y/120 into the dimmer rack. I am going to present this problem to the school engineer, and I just need to know if there is anything else I should mention as to why this is (or isn't, if so) a problem. Thanks!
