Monitoring Atmos in 5.1.2 speaker setup
Hi all,
Relatively new to Atmos here but have been searching in vein for an answer to this question.
We’re setting up a Dolby Atmos mixing room at our college using a 5.1.2 speaker setup and Pro Tools Internal Renderer. All working apart from this one thing…
Our speaker layout is similar to the 5.1.2 Overhead Speaker layout from the Dolby Atmos installation guide but L/R surrounds are closer to a 120 degree angle, ie slightly more behind.
The issue we’re having is that when I place the pan of an object or track assigned to bed to a position directly 90 degrees left (or right) of the “listener position”, there is no phantom image between say L speaker and Ls speaker. Sound is only coming out of the Ls at this position. As sound is then panned even closer to the back of the “room”, the level remains constant in the Ls speaker.
Is this the intended behaviour for this type of setup? If it is, I feel like the translation from placement in the 3D room window compared to perceived sound direction is way off. Or is there something with the way we’ve setup Pro Tools that could fix this?
Is there a way I could get those Ls/Rs speakers to act more like Lrs/Rrs speakers? Or can I monitor a mix that more closely resemble a traditional 5.1 speaker layout? (I’ve tried monitoring the 5.1 re-render but not had any luck thus far).
Ideally we’d obviously like to get 7 surround speaker installed but the space struggles to allow for it.
Appreciate any input.
Thanks,
Andreas

Have you experimented with different trim and downmix settings? A visual representation of the various downmix modes is available here: https://customer.dolby.com/content-creation-and-delivery/dolby-atmos-renderer-v530/documentation/dolby-atmos-renderer-users-guide/technology-overviews/visual-representation-of-51-downmix-options

I'm having the exact same issue here, but I cannot for the life of me figure out how to monitor my downmix in realtime. I'm mixing in Studio One using the internal renderer and panner, but routing to the Dolby Atmos Renderer using Dolby Audio Bridge.
Can you help me getting this to work?
Many thanks!
Matt
Is there a reason you are running the output of the internal Renderer in Studio One into Dolby Atmos Renderer application? Generally you would use a core audio output device directly out to your speakers from Studio One to monitor.
You can adjust your trim and downmix settings by clicking the wrench icon in the top right corner of the Dolby Atmos Renderer window and monitor the various outputs by selecting it in the output dropdown in the same window.

And yes there's a reason for that. Since I'm working with a 4.1.2 instead of a 5.1.2 (so no center speaker) I cannot use the phantom center with objects. The renderer in StudioOne doesn't allow for a 4.1.2 configuration, and the external Atmos renderer does.
So still waiting for an option to configure custom speaker layouts in S1 for now.
Also, I did think about that. The way I’m doing it now is by bypassing the internal renderer and just using the external one.
I made a 10ch mixbus that I use as the 7.1.2 bed. And for the objects I configured my IO for 64 stereo, and 128 mono objects (like in ProTools). I then use Dolby LTC generator for syncing, the Dolby music panner for panning my objects, and the studio one panner for everything in the bed. (Which I still think is a terrible panner since it’s spherical)
It’s a bit of a process, but it works well. I could do this in other DAWs but I like the built-in multichannel plugins in S1, and as soon as they add support for 4.1.x or other custom setups I can switch back to their internal renderer.
Thanks!
