My parents have a tv in their upstairs living room. They have 2 bookshelf speakers hooked up to a cheap stereo receiver. The receiver is powering the bookshelf speakers and ceiling speakers in the kitchen and dining room. When they are watching TV, they have audio coming out of the tv, bookshelfs, and ceiling speakers. There is a delay between the tv/bookshelfs and the ceiling speakers. If I get a better receiver for them, can I set the distance delay so they won't hear a delay with the ceiling speakers. It sounds like they want all the same sounds to come out of each speaker and the tv. Is that called mono? Or can they do stereo with that setup? Can the tv speaker be used as a center channel or does it only output all channels? I'm usually pretty good with this stuff, but these are some questions that have confused me.
