You're talking about Dolby Digital but streaming Atmos will be encoded in Dolby Digital Plus

What I find quite odd about the Denon diagram is the height level of the side surrounds. From my knowledge they should be quite high in the room. (I have a Jamo THX setup and they suggest min. 2 meters). Question is now if Denon always suggested to bring side surrounds at ear level or if this an "Atmos effect" as airspace now belongs to the ceiling/Atmos speakers?

Couldn't agree more. All my movie content is on shiny disc and is likely to be that way until the day comes when I can stream the exact same quality. But that's me...

If your existing Front Heights fall within the angle range of 30-45 degrees, then you can leave them where they are, and add another pair of top speakers and you are good to go. That other pair could be Top Middle, and the range for TM is 65-100 degrees, so do a quick diagram of your room and see where they fall in relation to your seating position.

Anybody care to speculate if these upcoming Atmos soundtracks will retain the original volume level when played on a non-Atmos 7 ch AVR or will there be attenuation, like when 7.1 tracks get lowered by 3dB on 5 ch AVRs?

They were pointing directly down, Roger. They also looked, as far as I could tell from a quick glance when the AT cover was briefly pulled back, as if they were conventional designs and not dual concentrics. I am expecting, as you are, that DC designs, with a wide, 90 degree all-round dispersion, oriented towards the MLP, will make a good difference and perhaps close the gap between the spaciousness of the Atmos speakers and the in-ceiling speakers I heard at both my demos. Then we will have the best of both worlds - the terrific spaciousness which the Atmos speakers create, plus the extra precision which the ceiling speakers create.

I believe he was referring to Heights mounted in the conventional 'height position' (ie top of the front or rear wall). You can of course mount a speaker on the ceiling and designate it as Front Height or Top Front thanks to the angle overlap: 30-45 vs 30-55 respectively.

Denon and Dolby say that their posted combinations will work well, even when FH speakers are used in the regular FH position, which is closer to the 30 degrees than anything else. Personally, I feel that the speakers should all be on the ceiling for the best result, even if one pair is designated in the AVR as Front Height, and I suspect that is what Marc meant. No doubt he will confirm or otherwise in due course.

At both demos I have attended the surrounds were all at ear height. The reason, I believe, is to create the maximum separation between the surrounds and the ceiling speakers (or just the ceiling in the case of Atmos speakers). The requisite phantom imagine between 'sets' of speakers won’t work well if some of the speakers are very close to some of the others - eg if the surrounds and the Top Rears are only separated by a couple of feet.

I am lowering my own surrounds for this reason. Incidentally, if more than one listener has to be considered it may be worth lowering the surrounds but still ensuring that they fire over the heads of the listeners, to prevent a listener on the left from having the surround speaker 'blocked' by the listener to the right, and vice-versa.

I think this might have been covered earlier in the thread but I can't locate it.

Can someone tell me.....what happens if you put 5 screen speakers up front? I believe atmos does/can allow for this.

In the cinema but not, AFAIK, at home. At home, typical screen widths would make it less useful than in a cinema where the screens are so much wider.

Dolby may have allowed for it in the home Atmos spec, but the real question is whether any AVR manufacturers will enable it as an option. So far, none of the mainstream manufacturers has.

since the Atmos objects are metadata and contained in the existing TrueHD /DD+ track, I would expect no change. non-Atmos AVR's will ignore the metadata & just process the TrueHD track as they normally would. that's my interpretation.

remember, part of Atmo is still the 7.1 conventional channels anyway.

The reason for the recommended 6' height was that this height allowed for a more immersive soundfield within the limitation of only one available surround height. Now there are two heights, this no longer holds value.

As Keith wrote, the effect will be less if the side Surounds and Overheads are very close to each other.

Think of it as a hemisphere where you try to spread out the speakers as even as possible, but within the guidelines of Atmos and the way it's implemented into the hardware at this point. Meaning you cannot put speakers anywhere it suits you, since the positions are preset into the hardware. It may come, though, if the processor can figure out where you have put the speakers via triangulation from multiple microphone points in the room.

Well, I doubt avs constitutes as much as 3% of the population, so there you have it.

Haven't seen it yet, but since that guy also dislikes matrix and avatar, I would not grant him a second more of attention for the remainder of my life..

JJ confirmed that Dolby are giving full capability to the AVR manufacturers to be able to use full speaker positional information. It is entirely up to the manufacturer to implement this or not, either by allowing the user to enter details manually or allowing the AVR to handle it through the measuring process which is part of the setup routine. Currently, as we know, none of the mainstream manufacturers is giving us this capability in their first generation Atmos units.

I'm beginning to think Yamaha might surpise us with the RX-A3040, because why else would they have just modified their angle meaasuring device? They've measured angles for years but only using 3 mic positions, and now they added a 4 position out of the plane so they can measure everything needed by Atmos. So for sure they will be measuring actual speaker angles, and if the rendering engine can use this information it's trivial for them to make use of it.

Also adding Atmos support in a later FW update means they can keep their powder dry and spring this as a surprise after everyone else is committed to fixed angles.

Very interesting. Yamaha has never been in the game for me before, but perhaps they just got into it.

So how do I use this Denon sheet exactly? I calculated that if I would go for installing front heights at between 45 and 30 degrees to the main listening position I would have a distance between 170 and 207 cm as distance between main listening position and ceiling is around 120 cm. Now my main speakers are at about 400 cm distance to the listening position. That means I would have to install the front heights somewhere in the middle between main listening position and main speakers. Are these tboughts correct?
BTW I found a really nice tool to calculate distances from the angles. It is in german but I think self explanatory:

I loved everything about it. I found it to be one of the most involving, immersive movie experiences of the year. I was on the edge of my seat half of the running time. The incredible sound and visuals perfectly complemented the story IMO. And to hear it in Atmos... well....

I do hope you are right. It would be great to see at least one of the mainstream manufacturers using the features Dolby have provided.

I've been a longtime fan of Yamaha going back decades. My very first 'proper' stereo amplifier was a Yamaha, decades ago. I sold it to a friend in the late '70s and, amazingly, he still uses it to this very day. How's that for build quality?

I only moved away from Yamaha with the advent of AV units because I attach so much importance to Audyssey's XT32 in my system. I am sure that if Yamaha had XT32, it would be my go-to brand. I am not all that familiar with the latest version of YPAO but I understand that it is much improved over earlier incarnations. Add that to the ability to measure speaker locations (if this comes off) and Yamaha might just be coming back on to the radar of a lot of people.

Front Height + Top Rear
Front Height + Rear Height
Top Front + Top Rear (default)
Top Front + Rear Height
Top Middle + Rear Height

Dolby have now confirmed, and even praised Denon for the fact, that those combinations will all work well.
So that means Dolby Atmos would be possible with neither ceiling speakers nor Dolby Atmos enabled speakers just by using front and rear heights at an angle firing about straight into your direction. This could solve my "low ceiling dilemma" as ceiling height should not matter that much! I wonder how this will sound!

And if the next gen of processor come out and support more channels I buy 4 Dolby Atmos enabled speakers additionally!

For me too Hollywood Sandra Bullock almost dies, I don't know how many times to miraculously make it then get to that Chinese space station and reenter the atmosphere..
Remember she was tumbling in space out of control screaming and flailing she should have died then.
The sound and video were amazing and that's what got me through it but the content was just too unbelievable..

Now my main speakers are at about 400 cm distance to the listening position. That means I would have to install the front heights somewhere in the middle between main listening position and main speakers. Are these tboughts correct?
BTW I found a really nice tool to calculate distances from the angles.
Yes, you are correct. In my room, using a 42 degree angle from the MLP, the Top Front or Front Height speakers on the ceiling fall in between the MLP and the front wall, which is perfect.

I just drew a scale rectangle on a piece of paper, using the scale 1mm = 2cm, to represent the room, measured where my ears are in the room and marked them on the diagram and then used my schoolboy protractor to draw a line at the relevant angle until it intersected the ceiling. Easy then to measure the distance from that point to the front wall - and bingo - you have your speaker position. If it isn't quite where you want it, then repeat using any angle in the permitted range for the speaker pair you are concerned with and you are good to go. Then repeat the whole process for the Top rear or Top Middle etc...

My first Dolby surround unit was also from Yamaha in the early nineties. Then I moved to Lexicon but they have just become too slow so I am looking into Yamaha again. I am going to the IFA in Berlin in three weeks where Yamaha apperently will announce /demonstrate a CX A5000 sucessor which will have Dolby Atmos!

In Denons at least, and supported by Dolby for Atmos, you can use Front Height and Rear Height speakers so long as they comply with the angles to the listening ears which are laid down in the specs (see the oft-posted diagram).

Both FilmMixer and myself have recently commented that this configuration might not be as effective as overhead speakers, but neither of us has currently heard such a configuration so we could be surprised. And Dolby specifically support that configuration so it must be, at the very least, a reasonable way to go or, presumably, it would not be a supported configuration. In my reply to this specific question (see my report) Stephen from Dolby said that while they (Dolby) are recommending a 'standard' configuration (using Top Front, Top Middle and Top Rear in 5/7.1.2 or 5/7.1.4 configurations) they also allow for the full Atmos experience with other configurations and indeed he commended Denon for making these other configurations available.

In your case, with your room, the configuration you are considering might be less than ideal, but still much better than no Atmos at all. I wish you well with it and would love to read a report of how it sounds if you do go that way.
