I pulled out a Behringer Eurodesk analog-style soundboard that's been sitting in the closet the other day, and decided I wanted to start a project to route a home theater setup for my small bedroom through it after recieving a couple bookshelf speakers.
The plan is to run an optical cable from my TV to a digital/analog converter to input the signal to the mixer, then output from the mixer with a small amp to the two bookshelf speakers. The television itself is going to act as the center speaker.
I just don't know if the signal will be strong enough after going through the converter to reach the mixer effectively, and if I'll need some sort of pre-amp or receiver to make it work. I don't have much experience with home theater systems at all, and what I would only describe as "just sufficient" understanding of operating the board. I've spent a bit of time the last couple days just figuring out how to choose an amp, so I'm probably behind the curve compared to anyone who's reading this post.
Any ideas/input would be appreciated. I also want to acknowledge that I know this isn't really a practical setup, and I'm really only doing it 1) because I think it might be cool, and 2) as a sort of learning opportunity. The soundboard was given to me after a local church switched to digital, so I figure "Why Not?" After all, the upfront cost of the soundboard was free to me.
What kind of outlook might I have in sound quality (or loss of) with this sort of setup, and what could I improve?
