I want to get a processor...Where do I connect the surrounds


I have a 7.2 set up...Marantz sr7013 running surrounds/center channel only. I want a processor...how do you guys run the center channel surrounds and back surrounds. Another separate piece? 
Thanks to all who can help...

The Marantz sr7013 has 9 channels of amplification & is a complete 9.2 channel surround processor.First I would ask why add an external surround processor to this?
IF you must use separates you will need an external amplifier as well,the Marantz can be used as a PreAmp/Surround processor BUT NO capability to use the amplification section only(which would be labeled as "9.2 CH Amp IN"I believe...
 
Maybe ask again OP what do you want to do?

A center only.

Two rears only.

That is how it reads..
