QC with SYN2 anyone?

I want to start using my QC in conjunction with my SYNergy 2 with a Synergy amp, 4CM. I got the4CM with the amp and QC and it sounds incredible. I am using the QC for FX only as I love the Synergy tube preamps and tube power. I am not sure ho to hook the Syn 2 into this thing. Any help would be appreciated.
