Realremo - is your question about the pre-outs because you want to be able to connect the Jolida to a subwoofer in your 2.1 system?
If so, another option, and one that is preferred by a good many subwoofer manufacturers, is to connect the speaker terminals on the amp to high-level inputs on the subwoofer, rather than go from line-level outputs on the amp to corresponding inputs on the sub.
Sorry if that's not pertinent to your question but your mention of wanting to run a 2.1 system made me think it might be.
