Reply to Using an S2 as a mixer

Hi all, first question so go easy.

I have purchased a S2 and loving it, just wanted to know if I could use it as a mixer with lets say Track Scratch Pro, x2 turntables/cdj's?

I know it hasnt got the S4 outputs to use it with the upgrade package but say I bought scratch duo 2/Scratch Pro 2 full packages with soundcard etc could I just use it as a standard mixer?

Thanks and merry Xmas to you all
