Hi, My friend and I got a simple Behringer 1204FX mixer in the mail today. It's going to be used to make podcasts etc, but we have one problem. I've used some audio equipment in the past, but most of it was still just jacks and RCA plugs. On this mixer though, the main outputs are 2 XLR sockets, probably both mono. Am I right when I say that there is no such thing as a twin-mono-xlr to mini-jack cable? We're trying to connect the output to his computer's line-in. There's also '3 and 4' outputs as well as 'control room' (REC) outputs, which are normal mono 6.3mm jack plugs. These have separate faders on the mixer. Is there a difference between these (the 3 and 4 ones) and the main outputs? How should we connect this?
