Digi 002/003: can I connect an Analog output to the line-in on my soundcard?

Can I connect the Analog (3-8) outputs to the line-in on my computer soundcard? The only input I have on my computer soundcard (P9X79 WS) is one 1/8" line in jack that I am guessing is unbalanced, -10 dbV. I do not have any digital S/PDIF inputs, or anything else that might be useful. So, in this case I would be trying to connect the Digi 002r's balanced, 1/4-inch TRS analog outputs (+4 dbV) into my computer's sound card (the P9X79 WS, which has one 1/8" line in jack, and once again, I am guessing is unbalanced, -10 dbV.
