I have the Neumann TM 103. I recently been having a problem. When I am in protools ready to record vocals the mic will cut off and on. I have to jiggle the mic cord at the connection point on the mic a little and then find the right spot and boom it is fine. And then it goes on and off more frequently and I have to do the same thing. THe mic hasn't been moved or dropped. I thought it might be the mic chord and went out an got a new one and the same thing. Is it something I can do or should I take it in to a shop somewhere. I am in Las Vegas. I just don't want to be taken Thanks.
