Recently when I use my Sennheiser MKH-416 mic, there is always a boost of high frequency noise (11kHz+,  -55dB),  which cost me a lot of time and effort in post-production.  

 

So I tried to conduct a experiment, using a K6/ME66 mic to compare with the  MKH-416.  In the experiment,  I used Sound Devices 702T,  and made everything else as controlled variables (time / place / direction/ gain/ input terminals… ).  However, no matter how the independent variables changed, the high frequency noise was always there.

 

Have you come across the same problem?  Is it an inherent self-noise of MKH-416?  Do you know how to fix it?

 

Please have a look at a picture of the frequency spectrum in the attachment.  

 

Thanks for your answer in advance.

 

Thanks.
