Has anyone heard a 9.1.2 setup?

9.1.2 is possible with Atmos. However, I've not heard that configuration.

 

Although, I'd much rather have 4 (overhead or upward firing) Atmos Speakers in place.... not just 2.

 

Since Atmos also supports Wide (Front L/R)... I'm considering that option.

 

I guess that would be 7.2.4

Your HT is like a Roman Coliseum. 6 subs certainly make sense in that space (and impressive). The beauty of Atmos is that its object based, not channel based. Leaving Atmos out of the conversation for the moment, the traditional channel based content of a 9.1 mix is authored in 10 "beds" (and that "bed" is assigned to a specific speaker or speakers). By contrast, the Atmos portion is not limited to a channel or 10 beds. The Atmos portion of the mix has 118 individual tracks to create the "path" of any object (or 118 paths for 118 objects). Traditional beds are limited to a 2D space, while objects are 3D. And, since the object is rendered in 3D, it can be panned front to back, left to right, up & down (basically where ever the sound designer wants to place the object).

 

Important to note, that pan path is not limited to just an Atmos speaker, whether it's an overhead ceiling speaker or an upward firing add-on module. Additionally, the object is not authored to a specific speaker, (for increased realism) the object is mixed to a point anywhere in the room. Since its mixed to a 3D space or point in the room.... that object path will pass thru every available speaker in the path (not just the ceiling, overhead or upward-firing modules). An Atmos authored track utilizes all your speakers, whether you have 5 traditional floor level speakers in place, 7, 9, 11 or up to 24. Its that combined mix of both objects & beds that provides the full immersive & overhead experience of Atmos. I've seen professional reviews where they were critical of Atmos Blu-rays because the overhead speakers "were not very active". That's not a fair or accurate observation. For example, Atmos can render a glass clinking in a restaurant... why would that make the overhead speaker active? It would not. Overhead or upward firing modules are key to Atmos by putting/moving sound above the Main Listening Position, but... only when it makes sense to place objects overhead (jets, helicopters, rain, music, etc). That said, Dolby Atmos Speakers / ceiling speakers are not the only place Atmos is authored, all of your speakers are included with an Atmos authored track.

 

Long story short, use Front Wide (L/R) with a 9.6.2 set-up. Atmos should recognize that configuration with both beds & objects vs. just traditional channel based 9.x.x. That's why I'm considering going from 5.2.4.... to 7.2.4 (using Front Wide L/R).    

 

 

EDIT: I have a pair of RB-35's packed away, not in use. A pair of stands & another Emotiva mini would make 7.2.4 possible with little or no effort. hmmmm.

I actually have 6 subs, so it would be 9.6.4
 this is probably my biggest pet peeve in this hobby. lol  :D  its all one channel anyways. doesn't matter if you have a million subs until there is two discrete lfe channels its x.1.x

 

Of course the LFE is one channel. But without specifying:  x.1.x.  /  x.2.x  /  x.4.x  /  x.6.x

 

No one would know how many subs you have in place. That's far more helpful information than if one just puts x.1.x

 sure they would! you list two subs in your signature. so i bet you have two. i list 4 18's in mine. listing you have a velodyne 12 and a polk 12 is useful. listing 5.2.4 only lets me know you have 2 bose bass modules  :ph34r:

x.1  /  x.2  / etc. is used in far more situations then a signature buried on a forum. Every AVR company uses x.1 or x.2 in their spec to designate that either 1 or 2 pre-outs are available. Denon, Yamaha or Onkyo don't really care what brand of sub's you have in place. Just because its your pet peeve... doesn't mean its not useful. Dolby has established the x.x.x standard. You can certainly choose to ignore the standard... but that doesn't change the fact that the standard exists.

and you can certainly ignore the fact that it annoys me lol cause you stating who set the standard or the fact that a receiver is sold to someone stating it is 7.1 or 7.2 doesn't lessen the fact that my pet peeve still exists.  :emotion-21:

The 11-channel Marantz 7702 has you maxed out @ your current 7.6.4 set up.

 

Are you 9ch via XLR & 2 (heights) via pre-outs?

 

If so, it looks like you still have 2ch available (assignable) via XLR for Front Wide (R/L). 

 

Use the Front Wide & add an external 2ch amp for 9.6.4.

In the typical HT, 4 atmos speakers should be plenty.  You want some space between them so that you can pickup spatial cues. :)

(lol) The quest never ends. :blink:  In addition to traditional imaging & room calibration, now with Atmos, DTS:X & Auro 3D... we have to maintain proper angular speaker separation & firing angles with the 3D triangular volume of a particular space.

 

We all have our "single" calibration mic for Audyssey (or MCACC, DCAC, or YPAO).

 

But, Trinnov, who has offered the first 32 channel processor (for 22.1.10 Atmos) has a new 3D measurement mic with 4 staggered, omni-directional capsules (forming a tetrahedron pattern). This will achieve (among other things) proper triangulation of distance, angle & elevation for spatial accuracy & remapping within a 3D soundstage.  Those "1" capsule Audyssey mics are so 2015 (lol).

No.. two different animals. I was just posting a uber-precise, big $$$$, extreme example of what our hobby has to offer. The Trinnov mic is designed to work with their proprietary systems & 3D mapping for items such as their Altitude 32 preamp (32 channels). Not really sure how an Echo can properly calibrate an AVR. You need to use the AVR's software & Atmos Renderer to measure, calibrate & remap any room measurements.

 

But no worries, all existing Atmos capable AVR's have the Dolby Atmos Renderer (software) & decoder built-in. And Audyssey can calibrate your room with the existing mic. I wonder if future AVR's will have the desire or find it necessary for a similar 3D mic technology to obtain even more precision. But the Trinniov system is around $20,000 - $25,000. Not sure how fast the tech will trickle down to more modest systems 

 

This a great video in the link below, that covers a lot of Atmos 101. A bit long & somewhat dry, but still an informative presentation about bringing Atmos to the Home environment:

 

 

I really like how he explains object based audio vs. traditional channels. It also touches on "spatial coding" and how the Dolby Atmos Renderer will know  & adapt to the layout of your room, and the number of speakers you have (or will have in the future). Basically Atmos is extremely flexible and an Atmos track will replicate the experience "custom" to your individual space. Your proposed configuration will adjust & fit with Atmos playback.
