A Couple of Atmos Questions

I should clearly define what I mean by "channel". I am referring to the left and right front speakers as one channel.

So this my set up:

Front speakers channel, left and right - one amplifier
Back speakers channel, left and right - one amplifer
Center speaker channel, mono - one bridged amplifer
ATMOS channel, left and right - one amplifier

My question concerns the ATMOS channel. If one has more than one set of left and right ATMOS speakers, are all of the speakers playing the same source material?

Thank you. John
No, if you have four height speakers each speaker will have discrete sounds coming out of them, similar to your floor speakers, most atmos mixers work in 7.1.4 so eleven seperate channels of sound, although if you only have two heights like me the sound will fold down

Atmos is designed to scale depending on the setup. If you have an Atmos receiver that does 9 or more channels, then it will utilize all four height/top channels.
 
And you're defining a channel as one speaker, left or right, correct? That makes more sense, actually.
Yes. One speaker equals one channel. Atmos does use four top channels IF you set the configuration in the speaker setup to the correct layout. A 7 channel Atmos receiver is limited to 2 top channels/speakers. A 9+ Atmos receiver will have the speaker layout options to utilize 4 discreet top channels. A 9 channel receiver will go 5.1.4. An 11 channel receiver will go 7.1.4. Beyond that, for 6 channel tops, it gets very expensive for the receiver/processor.

Thank you for the clear explanation. I presume all of the musical info for the four discrete channels will be heard in the two that I have, so I can live with that. Thanks again.

From my experience, with two different receivers, the Atmos is summed to just the two channels and will work best directly overhead. My Yamaha and Denon doesn't make any compensation if you set them up as front tops/heights or rear tops/heights. All the Atmos info is simply added to both channels regardless of settings. DTS-X will send height sounds to the front channels if the configuration is set for only rear height channels. Vise-versa if you set your two heights to front tops/heights.

That’s usually what “channel” means in the audio world. I believe your use of the term to describe TWO amplifier / speaker connections is the source of a lot of confusion here. It took me analyzing your connection diagram to figure out that that might be what you meant.
