Yeah man I have the Mg 10/2. I have to work around mine in order to hook it up to my p.c. It's not a very good board I don't think when it comes to the mic pres. Wish I could help you get it hooked up, but it should be rather simple since you got buss outs on that mixer. Are you just trying to get it hooked up to your pc?
If you're using the group busses to output to your soundcard remember to pan each channel pair hard left & hard right, otherwise you'll get bleed between the channels.
If you're not using the group busses you can go 'direct out' to the soundcard from the inserts
