There was a pretty bad case of hum bars on the projector in the main events room this year (light bars that slowly rolled up the screen). It was definately caused by a ground loop, no question about it. Maybe the con could invest in some ground lifts for next year? Or even try to power the projector from the same outlet that everything else is getting power from.. it would of course mean a long extension cord, but that would at least minimize the chance of getting a ground loop in the first place. Just a suggestion wanted to throw in ..
