How many sets of stereo monitors from XMON?

Looking into a new controller and haven't been able to find much info on the xmon hardware. Can someone tell me how many speaker outs XMON will give me with an ICON or S6? I'm currently using a C24 with main monitor outs going to a full range system with sub, alt monitors going to a pair of avantones, and the SLS output going to a small set of passive monitors. How will XMON handle this monitoring setup?

Thanks for any insight before I make the plunge.
