if you want to maintain your stereo signal you need to make sure every step of your signal chain is stereo. this includes using a a stereo DI box (or just two mono i guess). while you could convert to rca, i really don't see any reason to unless you want to use multiple adapters (each of which adds a little noise) or the tape input on your console.
i would recommend a cable like this: http://www.amazon.com/Hosa-CMP153-Cable … B000068O3C
it's pretty inexpensive, and if you have your own submix just send each of those to separate channels like vegas said, or just use a stereo DI, and send it straight to the house console. a stereo DI might be something to invest in, but any venue that is serious will likely have one on hand. that being said, i would strongly reconsider how worthwhile you feel hard pans are in a live environment.
i think there's a discussion about it somewhere in this thread: http://chipmusic.org/forums/topic/12403 … eo-issues/
good luck dude!
