I am planning to use an Emotiva UPA-7 (got from their last shipment) with a sonos ZP90 to power 3 sets of stereo speakers and maybe 1 sub.
I am wondering what is the best way to split the output from the Sonos so that the 2 stereo RCA outs can go to the 6 inputs on the UPA-7? I am a bit scared to just use a bunch of Y-connectors as I am not sure how it will affect the pre-amp signal before I amplify it. If that isn't a big deal, cool, but I am weary just hooking it up that way. I haven't found much on the internet in the way of rca splitters that are beyond just a y-connector.
I have considered just using an avr to do this assuming it has enough pre-amp outs, but that is overkill for when all I really need is a splitter.
Also, in an ideal world, I would use the last channel on the UPA-7 to power the sub for that zone as well as opposed to switching it with a different sub on another sub amp I have (would be a pain whenever I change zones). Of course, though, I would need a crossover in between the Sonos output and that sub. Anyone know of any decent stand-alone crossovers that won't break the bank?
