The easiest and cheapest way to be ready for this is with:
1 rca (male) > 1/8 stereo (to plug into your deck)
2 1/4" (male) to rca adapters
2 xlr (female) to rca adapters
This way, you are ready to take any rca, 1/4", or xlr outputs. Some people advise adding a pair of attenuators, but I have never needed them.
