Ok, long story short, I am a volunteer Church Technically Specialist. Basically it means and since I know a little bit about technology they asked me run the COVID broadcasting and the Audio System in our chapel.\n\nWhen the church upgraded it's broadcast system, which the old XLR Audio system feeds into, all all of a sudden if you plug anything into the XLR system that need to be be plugged into a 120 V socket you get a ton of static (like the static sound on an old television)\n\nI've tried adding a "Ebtech Hum X - Plug-Style AC Voltage Ground Loop Hum Eliminator' and a "Hosa GLT-255 XLR Female to XLR Male Ground Lift Hum Stopper" hoping it was a ground loop or something.\n\nDoes anybody have any suggestions on things I might try. Remember it only happens when you plug in something that needs 120 volts. Regular mics work battery, powered computers will work, and even battery powered microphones will work if the pickup is battery powered also. I really don't want to fly the installers back out her.
