i like my usb mic..id say invest 100 on that..phantom power is also an effective method,does your mixer have phantom power?..ive never heard of using rca cables though? or guitar plug in? well if thats what your doing... hmmm...maybe something to do with the ground?
I say RCA because my Behringer Xenyx came with a usb sound card. Most mixers do. Or you can go through the back outputs with a guitar cable with adapter. Makes sense if you look at a mixer ^_^
