I just finish a weding. To my surprise found a 4 seconds sound drop out in in the midle of a song. I'm wondering if I have done something wrong or was it the camera that fail.

Hi Mike,

Not really knowing anything about your set up, it is pretty tough to say what went wrong. If the image and timecode are intact on the tape during those 4 seconds, I'd guess that it is very unlikely to be either the tape or a fault in the camera electronics. In general, an accidental switch throw or loose connection in the audio path would be more likely culprits.

Often you will get a dropout that dosen't show on the video but rather only the audio. Often, in Post, it will show up in the video too.

Thank you for your reply, this happend 2 times on the same video, the first time lasted for 4 second the second time 2 seconds. I used ME 66 mic. this is a fairly new mic. with hardly any used, no adjustment was made at the moment. I will be very carefull next time hopefully it was just me and no the camera.

So the Me66 was connected directly by XLR cable to one of the XLR jacks in the back of the XL2?

The variables I can think of to try diagnosing this would be:
- the XLR cable itself
- XLR connector
- power to the mic (battery vs phantom power issue)

If you mix-n-match different parts of the audio path during test recordings, you should be able to duplicate and identify the fault. I'm not very experienced with audio, but my bet is on a failing XLR cable -- which is what I'd hope for as the fix is easy and cheap! Second choice would be the XLR connector itself, either on the mic or the camera. A short disruption of power to the mic could do it, too.
