Could be your adapter, I know I had an issue getting a trs mic to work with what on the outside looked like a mini connector trs, but wasn't, I needed to use a trs to ts adapter to even get it to work. Or even the camera, pretty sure that wad my issue.Correct, I think it is a TRS connector. That is the type of cables I used when I hooked everything up. As explained in earlier posts. Quite a lot to read on this thread.
