I am setting up a condenser mic for my ProTools 8 system on the Digi 03 interface. I have a Neuman TML 103 mic running through a 25 FT Planet Waves XLR cable. When I turn on Phantom power and put the gain at about 50% the mic starts to pick up random high-hissing electrical sounds that come in and out.
I recorded it and put on SoundCloud https://soundcloud.com/fireflies-the-musical/static-noise-condenser-neuman-tlm103/s-BI5UX
The Noise comes in at 0:11, and then 0:23 and many other places. My phone was on the table about 10 feet away and I had no other electronics on me. When I got loser to the mic also, are around 1:00 there is another hiss that comes in. The only thing plugged in now is my Mac Pro, Monitor, and DiGi03, all going to the same power source, a surge protector plugged into another surge protector.
Any help on getting a clean sound is much appreciated.
