Thanks to both of you for your responses, I appreciate it. I checked out the information you guys provided but neither fixed my issue. I dug a little deeper and I finally figured it out.
I was confused by the Output/Send routing, along with the first SPAN input not clearly stating it was an input like the other 3 available inputs. In FL Studio I would set the Output of a Mixer Insert directly to the Bus housing SPAN. In Sonar's case you keep the tracks outputting to their default Bus or Master and use the Sends. The input titled SPAN is in fact input 1, and the other options are listed properly as inputs 2-4.
Another problem is the VST3 version seems to only have 2 outputs, while the VST2 version has 8. The VST2 version for some reason is listed under Soft Synths rather than Audio FX.
Hopefully this information helps anyone else having issues with SPAN. Again, thank you guys for the replies.
