According to the spec page at the M-Audio website, the Audio Buddy has a pair of independent 1/4" outputs - unbalanced or balanced TRS. One for each mic you have plugged into its inputs. The RCA inputs on the Audiophile are not balanced, so you need cables with one standard mono 1/4" connector on one end (just like a guitar cable) and one RCA plug on the other, not a stereo pair. You need one for each of the Audio Buddy's outputs, and you should consider them as two separate mono sources, not a stereo source. It's best to record mono tracks in your recording software and use panning and stereo effects to give your final mix its stereo image.
