I have a Sony UWP-D Wireless Lav Mic set and I'm experiencing difficulties with audio in my office building. I can film any exterior shots with no issue. I also have no audio issues with audio within an enclosed staircase in a parking garage.
But when I use the UWP-D Mics when filming in my office building, the sound drops out every two or three seconds. Due to this only being observed in my office building (so far), I'm inclined to believe it's in the building and not the devices - but I'm more than willing to try any suggestions if anyone else has experienced the same issues with these or other wireless lav setups.
