Hi guys,
I'm testing for some interviews next week and when I plug my wireless mic receiver into the 3.5mm mic jack there is a persistent ground loop/digital processing noise in the background. It's not overwhelming but it's enough to make the audio problematic. I don't have any wireless transmitters or any other accessories on the camera. It's almost like the 4D input isn't shielded properly or something.
I never have any issues with my Panasonic camera splitting the audio into twin XLR's, I really don't think my mics are the problem. In the below clip I've turned the audio up so you can hear it better.
I wonder if DJI have any input on this as I never got any feedback on my last query on here.
