Receiver: denon 1712 Fronts : pioneer fs52's Center: pionee cs22 When watching tv if the channel has hd audio the front speakers do all the background sound and the center does the vocals, is this right? I'm new to this and I assumed they all played the words not just the center. Should the right and left front be picking some of them up? Or is this hooked up right? When I switch to a channel where it has no hd audio, the center cuts off(receiver switches to stereo) and just the fronts play but now are also playing the words. Again not sure if this is standard or if I have something in the settings wrong.
