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.
Thanks
Mike

"TV as center channel" - older projection sets often has a "center speaker input" and a setup menu selection that allowed the built in speakers to be used with a surround a/v receiver (5.1 or more with dedicated channels for surround speakers) and used as a center speaker. Most flat panel TV's do not have this "feature".

When playing TV audio through a stereo or a/v receiver, you should turn the TV sound down to almost nothing - there will be an echo effect due to the slight processing delay of the external electronics vs. the built in TV audio. One or the other, TV sound or external sound - something to experiment with anyway.

Are you saying there's no delay between the TV and bookshelf speakers, but there is a delay between that combo and the ceiling speakers....which are driven by the same amp as the bookshelf speakers?
If so, the delay from the ceiling speakers is probably due to their distance away from the TV. You'd need to delay the TV and bookshelf speakers to match the delay due to distance. Since the bookshelf and ceiling speakers are driven by the same amp, it's not going to be possible, and will throw lipsync off as well.

no, there is no delay between the TV and it's internal speakers....once you feed audio output to another external amplifier the very slight delay can be introduced and that can be noticeable when both the internal speakers and the external amplified speakers are playing. A very slight delay can sound like an "echo" or "reverb", where a longer delay will introduce a noticeable shift in the two audio sources.

Assuming analog connections, how would a delay be introduced?

Are you the OP?
