Hi dears,
I'm a newbie who would like to split the mic signal both to the camera and the iPad simultaneously. So I did this nice cable split. But...
If I connect everything, the camera and the ipad receive no audio at all!
If I connect only one of them (be it the ipad or the camera) it receive/record proper audio.

What am I missing?
