What's a better output connection for HD Omni?

Need a lil help for output routing using the HD Omni. I'm correctly using the Trs 1& 2 outputs going to a Samsung C-Control to be able to utilize the Sub-Woofer output & TalkBack on the Samsung C-Control. Wondering if I could achieve a better setup(sound) by using a DB25 cable for output routing & just setup different monitor mix's for the Subwoofer for when I don't need it! Or maybe there a way to route that I'm not aware of.
