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?
Thanks for your answer in advance.

I've never heard of a 416 doing this and browsed a few pro audio forums with no one reporting it.
I'd recommend a trip to the mothership (i.e. back to the factory for an overhaul) to repair the problem.
If you live in or near a major city, there are pro audio shops such as Trew Audio, Professional Sound Services and Gotham Sound to name a ferw that may be able to help.
You can also try posting this question on http://jwsoundgroup.net/, a forum for audio professionals who do this for a living and see if anyone there has any other suggestions.

The 416 requires 48vdc phantom power. Are you sure you are getting 48v to the mic? I would assume the Sound Devices supplied 48v phantom . . . but is there provision to switch the mic power to something less?

Melody Zhao, were you ever able to determine the cause of the hiss? I have the same problem and even Sennheiser was unable to help me.
I know this was posted 4 years ago, but I can’t find anyone with a similar problem anywhere but here.
