And Dolby Atmos speakers set by Klipsch, which includes two R-625FA, one R-52C, on pair of R-51M, two R-610F, one pair of R-41SA and R-120SW. The player used for this test is Panasonic 4K Ultra HD Blu-ray DP-UB820.

I evaluated the quality of the receiver’s sound on different scenes – from calm ones to gunshots, plus paid attention to dialogues and their clarity.

And as noted above, the decoder part of Dolby Atmos will adapt to what you have at home. It seems like today many home systems are sold as 7.1.2, that is 9 speakers and one subwoofer. The more speaker channels your playback equipment has, the better the resolution can be, ie you might be able to better pinpoint the sound in 3D space. If your playback environment has speakers above your head the playback equipment will "move" the sound around including above your head. Once the helicopter has disappeared from the sound scene, the same "object" may instead be a seagull or whatever.

One example of an "object" might be a helicopter sound moving around in the space above your head. The placement is done by playing back the sound in several speakers at the same time, perhaps a little stronger in one and weaker in a few others, all in order to allow your ears to hear a 3D space. But if fewer speakers are available, it will use whatever there is. The decoder (basically a complicated computer program) in your playback equipment will do its best to map these objects to the available speakers, up to 34 for home use. I believe the limit is 128 concurrent "objects", most of them can be placed anywhere in 3D space by the recording engineers.

The sound is not transferred as channels, but as "objects" placed in 3D space.

Dolby Atmos adapts to the actual number of speakers available.
