[QUOTE="Shane Presley, post: 2377, member: 110"] I have a community center ( converted old chruch) - that I have been struggling over the past year to get their lighting dimmers situation solid. I had 4 x leprechon LD2400 in there, and there is 4 bars of 6 1K pars, and 2 bars with 12 lekos (6 per side) on it. I replaced the leprechons with 2 x CD80 packs, re-built etc.... I THOUGHT everything would be fine, until the co-ordinator for the space texts me , and says there's a loud buzz near where the camlocks connect. the cams were put in by a contractor, nice grey box, lockable etc... anyway it's located at the back of the stage. The church is being used by an orchestra for rehearsal performance space, and the conductor will "lose his shit" if he hears this buzz... (He makes the centre turn the ceiling fans off - installed 55' up). So any ideas how the CD80's are "buzzier" than the leprechons, or how I might go about masking this power draw buzz? BTW - the dimmers are located in the basement, not in the same room as the stage... I am coming off the cams at 200 amps, (down through the floor) to a junction box to 2 x 100 ( knife switch disconnects), then BX to the cd80's.... This is the picture in the basement - from here, the cams run up through the ceiling and tie into the building cam box ( a more rectangluar, off the shelf box) located directly above this set-up...
