Greeting all,
I have a reasonably professional home studio: 2 Tascam DA-30 8 track digital records (16 tracks total) Grace 101 pre amps, and a Mackie Digital 8 bus mixer. I recorded my last CD with this set up with excellent results. There was one problem however. I perform primarily acoustic music (guitars, resonators, bass, mandolin etc) and one of primary mic set ups is to use a pair of Neumann KM-184s in stereo. For reasons I cannot explain, I get an unusual interference with the KM 184s. It is a high end radio interference of some sort (NOT a 60 cycle hum) which is very sensitive to where the mic is placed in the room. The problem is so severe that I could only record in one very specific location. Moving even an inch to either side would create interference.
I've talked to numerous sound pro's including Neumann and have purchesed Neumann cables ($60.00 a pop!) and Blueberry Kiwi cables to no effect. These lesson the interference somewhat but do not remove it. I do not have this problem with the other mics in my collection (an AKG 460 mic, a B.L.U.E. Blueberry mic or a Rode large diaphram mic), but their sound isn't as good as the Neumann's. I'm beginning to suspect there might be magnetic field interference in the room. Does sanyone have any suggestions on where I might learn about magnetic field interference or have any other suggestions about how to deal with this?
Thanks!
