Im working on building a simple home studio, and things are subject to change...but as for now, this is what I plan to be getting. This external sound card M-Audio Sound Card Along with these monitors M-Audio BX8 Moniters And then with this Subwoofer M-Audio SBX Sub. So heres my question...I looked at the manual for the sound card, and I see the line outputs for the moniters, and it has 4 output lines, so then would the 2 monitors and the sub each have there own output line, or how would that work? Thanks
