Hello Michael and welcome to the Cow Audio Forum.
I think what you have here is not uncommon in situations in which you go directly from mic to camera. Let me talk it through, though without the mixer.
Mics can, themselves, overload before getting to a transmitter or camera. If the mic too sensitive, you have to use a less sensitive mic.
The input of the transmitter could be overloaded by what the mic is picking up , even if the mic is not distorting. That’s an adjustment on the transmitter.
The fact that your FCP footage is a -12 means you probably weren’t overdriving the camera input, but with no way to calibrate the receiver to the camera, you could have been sending line level from the receiver to a mic input on the camera. The receiver output could have overloaded the front end of the camera before it even got to the camera input controls.
The term is “gain staging” you need to know that each stage is properly set to get the loudest audio that doesn’t get too loud and distort somewhere along the chain.
How’s that work for you?

Ty Ford
