Can you help identify the problem with the distortion in the vocal mic in this clip? It's a Shure GLXD system. Wondering if the problem is proximity to the Allen & Heath ME-1 mixing console the choir director is using? https://youtu.be/QBoEL3tZdbk
Debbie,
I am not a fan of the GLXD system, one of the singers in a wedding band I worked for had one.
Because these operate in the 2.4GHz spectrum they are constantly being hit by phones and other Wifi garbage. One of the issues I discovered (when hearing that same crunchy drop-out sound you are hearing) was the GLXD receiver was too close to the router I was using for my mixer. Moving the two away from each other helped, but didn't completely fix the issue.
I tried changing the channel the GLXD was using (it is supposed to find a clean frequency on its own) but could never get the unit to operate trouble-free for any extended period of time.
The singer finally sold the unit and got herself a Shure SLXD which operates in the UHF band. No issues since then (and I always scan the venue prior to a performance).
Just my 2-cents.
