Sony wireless into Canon 60D
 

Okay, while I have used wireless mics for many years, I'm a recent convert to DSLR and still fumbling around with it. In the process, I found that the Rode VideoMic Pro works well when the audio gain on the camera is cranked down and the mic is set to 20db. But when I hook up my Sony UHF wireless the audio sounds clear but muted. Just for grins and giggles, I plugged the cable into the monitor out jack on the receiver, instead of into the regular audio output jack. The audio in the camera is now crisp and clear and has perfect volume..

Howzat? Is the monitor out jack acting like a line into the camera?

And are there any risks to the camera doing it this way?

Thanks,
Charles
