Weird "warbling"
« on: January 19, 2020, 12:30:51 pm »

We are in production of a show, using two Shure GLX-D1 among 10 other headsets. This is a small, intimate theater, with direct line of sight to the receivers. It is about 50 feet from the stage to the receivers. These two mics cut out about 3 or 4 times a second, giving this warbly sound. Dont know how else to describe the sound. Maybe "gurgling" would be another way to describe it. Weve tested them even when all the other mics are turned off. And we have tested them individually. In both scenarios they still do it, so we concluded it was not a frequency conflict. Any ideas?

Are these two units in the same WiFi channel as a nearby WAP or other 2.4GHz production element (lighting, automation, etc.)? Have you tried changing channels/frequencies to that of one of the "good" units?

Do you hear the warbling sound when the mic elements (headsets) are disconnected?

GLX series are in the most horrible spectrum .
  the receivers need to be as close as possible to where the mics will be used . Good luck

Are all of the systems GLX-D1? I'd have to look up the specs, but most 2.4 GHz systems have a very finite limit of how many you can use simultaneously in the same space, and ten seems like a lot. From your description of the issue, it sounds to me like both units are trying to use the same channel at the same time, Again, I haven't used this system, and haven't looked at the manual, but I encountered a similar issue with some lower end Shure product (possibly in 900 MHz) that had both been synced to the same channel.
