Over the last month or so, both of my WL183 mics have begun to pop hysterically. It doesn't appear to be the mic's themselves, and the receivers don't pop when I use them for my wireless handhelds. We tried changing the frequency/band but still encountered the loud pop. Would the body packs be able to cause these pops?
I suspect that the WL183 mic elements need to be re-tightened. Remove the foam windscreen (if there is one) and tighten each element as tight as possible using fingers only.
