You'll need a mixer to do this, consider contacting a PreSonus reseller to see if they'll let you demo a console to determine if you want to buy it or not.
Alternatively you can register a My.PreSonus.com account, get a demo of Studio One Professional for 30 days, then if you don't buy it, use Studio One Prime which is free to use with many of the same mixer features available in the mixer.
