The CMIT I am using was purchased last year, April, and it mainly stays in the Blimp Windshield. Last week I went a set. It is a genuinely dusty indoor environment. So I paid extra attention asking the boom OP do not take it out of the Windshield. However, on the second day of shooting, The mic starts making weird noises like this.
It is recorded in a quiet indoor condition. But the self-noise is extreme. I do saw on Schoeps website saying
Not too sure if I should send it to do the services. It happened twice on my three-day shooting, so I do have a strong concern about it. If I sent it back, do I have to send it back to Germany, or I can do the service in the state.
