Hey guys. Lately I hear a high-pitched whistle on my 7D's soundtrack. I use the sennheiser mke 400 and the battery LED does not indicate that the battery was low or anything like that.

Any ideas?

Do you hear this when you play back in the camera too?

You haven't accidently hit the sensitivity switch of the mike?

 

[FixMix]

yes it is in the camera as well.
No hit that I know of. Why?

I'm sorry, English is not my native tongue. I meant: did you put the mike in the more sensitive mode, by accident?
To me it sounds like the auto gain is in overdrive.

No problem, mine neither

No I tested all settings (low/high gain etc.). I was in contact with my seller by now. The mic will be replaced because I've bought it less then 30 days ago.
