Hey All, My church has used two XD-30 with the handheld transmitters for since 2010. We recently replaced one of them with a XD35 and have started having issues with the XD-30. We also have a XDR95 with a lav mic on it. Any time the lav mic gets near the XD30 I get a high pitch static type noise that I've never had before. I've tried changing channel with no luck. Any ideas?
