[QUOTE="Shane Presley, post: 35139, member: 110"] Re: Cam lock power hummm / buzz.... Thanks Guys, I did and on-site, and it's basically when she has the dimmers at 50%, that there is a SLIGHT buzz. The problem is her orch conductor client... he MAY cause a fuss etc... I mentioned she might be able to build some sort of cover over top of the cams that is insualted, to mask some of the sound. There's nothing I can do electrcially, as everyone has mentioned, other that maybe opening up installed the cam box (which I would rather not do, especically when it's under load) to "feel around" for a vibrating component. It definitely vibrates at 50% load, but goes away in the last 3% before 100% on the master. Thanks for the ideas. TJ, could something in the dimmer be transferring that buzz up 50ft of 2 ott cams to that connection, causing it to vibrate?. it is the 60hz buzz, I'm just wondering where to start to isolate , and look for it. the dimmer packs are buzzing , but they are in the basement. the cam connection upstairs is making the same noise as the dimmer packs...just at about 50% of the volume. again, it all goes away at 100% master full on , or off....
