Hi boys and girls, I've tried looking this up, and didn't find anything helpful, but something tells me it could be a pretty common issue. Maybe you can help me figure it out. In a nutshell: I was recording some pretty cool drums with my Fast Track c600 (that's 4 channels) and at some point my recordings started getting a lot of noise, but only when I use either of my two condensers (I have a MXL v57 and a behringer). My recordings are still very much to my liking with my dynamic Shure SM58, or when I plug my Les Paul into Guitar Rig 5 and mix it all together. Being a heavy rocker, I don't mind going dynamic on the vocals. But creating a stereo field with the built-in mics of my TASCAM DR-40 is not ideal for drums. Could this be a phantom power issue? If so, is there a way to take care of it (without having to throw out this interface and buy a new one)? It's not the mics, cause they both get the exact same noise... neither is it the cables, cause I have several and ran tests.... I've tried with the interface on USB power and with the power plug on... I don't have electrical grounding in my house, that could be it (maybe?). Guys, I dig your wells of knowledge, please help a struggling brother out. Peace!
