I'm going crazy here...I feel like this should be something simple, but I can't find what I need. Basically, I'm setting up a home theater. I have everything else put together, but I need a way to easily route and switch the audio channels from various devices (TV, Xbox, DVD, Music, appletv, etc) to my speakers. The thing is, they're powered speakers, and all the home theater receivers that I can find are amplifiers as well. I don't need an amplifier, and on the receiver that I have now, the volume control doesn't work on the direct line outs, just the amplified outputs. So I just need something that I can plug a bunch of audio sources into (4 stereo channels would be enough), have a single stereo direct out that goes to my speakers, and then a master volume control for the output (to the speakers). Can someone point me in the right direction here? I know I could just plug everything in a little Mackie mixer that I have, but that doesn't really fit with the whole 'home theater' look/feel.
