This is not normal for a MKH-30, their self noise is a very smooth
paaaaah sound.
You need to verify that it's actually from the mic and not something
from cabling, a poor contact in a XLR, your phantom power, etc. If it's
from the mic for sure, then record the sound and send that along with
the mic to Sennheiser.
I know that here in the US you can call Sennheiser and talk to their
techs about a problem. If they know what they are looking for it's
easier. On a intermittent I'd definitely call.
