still having problems

[jacks763]

I really fill silly asking this question, but MTU tells me that they do not send manuels with the computers that they sell, that I can get the manuel from help in the Hoster progam, that only gives information pertaining to Hoster and I don't know how to hook up my computer to my mixing board. This unit does not have av\rca jacks, that I'm familiar with and I was told by Radio Shack that there is no adapter available. How do you get your audio from your computers to your amplifiers?
