I recently picked up the Denon AVR X510BT for my home theater setup. We have 8 speakers wired in my house, 4 in my living room, and 4 in other parts of the house. I realize the receiver I have isn't able to take advantage of all those speakers, but we didn't have the money to upgrade to a 7.1/2 channel receiver. I'd like to have 2 of the 4 speakers in my living room working for when we're watching TV, and the rest available (although not necessarily at the same time) if we want to listen to music. Right now, I can't find a way to use only the 2 speakers for watching TV in my living room and the rest for listening to music. There doesn't seem to be a setting where I can select certain speakers to be active in certain modes, and other speakers active in other modes. furthermore, it seems that when I do play music through all the speakers, they all sound different in different rooms because I plugged the speaker wire into slots designated for tasks the speakers weren't designed for! Is what I'm asking for even possible with the receiver I bought? If not, let me know so I can return it for something better.
