Hey guys, I'm new to home recording and need some help... I have the AT2041SP (AT2020 Side-address cardioid condenser microphone and AT2021 Small-diaphragm condenser mic). I've been trying to get a clean sound out of it using the usb (printer cable style) on my Peavey 8 Mixer but to no avail... I always get this weird high pitched ringing noise in the background. At first I thought this was normal, but when I asked my buddy cole (http://www.youtube.com/user/20hurtztv) about it he said it definitely wasn't. I brought my equipment to his house and he was getting the same thing on fruity loops that I was getting on Reaper. However, once he plugged it into his DI (which then led into his computer) the sound quality improved dramatically and we didn't hear the ringing noise at all. This is also true when just using the headphone out as well. I'm seriously considering getting a DI because of how frustrated I am at this point, but if anyone knows anything that could possibly help, any advice would be greatly appreciated... Heres a small rendered file of me saying test a few times http://www.filedropper.com/problem Thanks guys.
