I haven't seen any reasonable discussion of why Dirac at 96/24 will be better than Dirac at 48/24. Do we need Dirac room correction that works at frequencies above 24Khz? Dirac Live that samples at 96/24 is available on some processors and Mini DSP units. So, apparently Dirac must believe there is some value in a higher sample rate. Dirac Live on Emotiva processors down-samples music files above 48/24 to 48/24. It seems reasonable that removing the need to download-sample would be advantageous.
For me its just figures.

Thank you Mark/all for getting all of this info out to us!!! Some questions (sorry if I missed the info in the 8 pages I read through): - with respect to the RMC-1+ demo......was there any popping of the speakers as the processor changed audio modes etc? Are they finally gone? :-) - did anyone ask about how the exchange/upgrade program would work for people outside of the USA eg in my case Australia? - When will the shop be open for us to buy the new processor (I understand they will ship Q1 2025, but wondering when the purchases can start)? - Left field/dumb question. From the pictures I can see the Pi4 (a Pi Compute Module 4 - anyone know how much memory?).......it looks like its plugged into a proprietary motherboard (hard to see) using the Pi's 2 x 100pin high density connectors? I wonder if this can be maybe upgraded in the future with a Pi Compute Module 5 (mechanical/pcie/os allowing) if more grunt is needed? Thanks again. Jim I did not hear any noises during the demo. The switching was also much faster. |

anyone took video of the demo, so we can have a gauge of the new switch performance, how fast it switches etc..

So, will the expansion boards be available for the RMC-1+ right out of the gate or down the road. It sounds like the RMC-1+ can presently support 9.1.6 with a path to 11.1.8 and finally 11.5.8 or does it actually presently support 11.1.8 then later will support 11.5.8? If it presently supports 11.1.8 (obviously with the need for expansion cards) does that mean that it would presently support 9.4.6 or do we have to wait for multi-sub support when 11.5.8 support arrives? Sorry, this is still a little unclear to me. (9.4.6 is my personal configuration of interest) Also, is the full compliment of HDMI 2.1b features supported or is it a case of only some of the 2.1b features being supported. 2.1b features I am wondering about are: Dynamic HDR Source Based Tone Mapping Auto Low Latency Mode Quick Frame Transport HDMI Cable Power (to power active cables) It sounds like Variable Refresh Rate and Quick Media Switching is supported but maybe just a verification there?
What does 'enhanced' atmos decoding mean? What does it do here that couldn't be done before?
Finally, their original soft launch features included being 'music streaming capable', what does that mean?
Thanks for the great write up, much appreciated! The way I read this is technically dolby supports home standard layouts up to 11.1.8. I don't think this means the RMC-1+ has it and it sounds like subwoofer expansions are also on a wish list of possibilities which I would imagine are higher on the priority list with dlbc and the competition coming in at 9.4.6. I sure would hope that they would honor a trade in when and if the expansions become available. But I do believe it sounds certain there won't be any possible 11.9.8 support etc. Sounds like 24 channel theoretical limit is confirmed. Thanks for trying to answer this Irobertson.
Looking at the Dolby Atmos Home Installation guidlines they do say that they support up to 34 speakers:
"Figure 1: At left is a Dolby Atmos system with five speakers on the floor and four overhead speakers; at right is a Dolby Atmos system with up to 24 speakers on the floor and 10 overhead speakers." pg. 4
"In addition to the typical configurations in the previous section, Dolby Atmos can support more speaker positions, up to a maximum of 34 total (for example, 24.1.10)." pg. 51
What I think I've gleaned from the thread (plus maybe a healthy dose of presumption?) is that the XMC-2+ and RMC-1+ offer up to 9.1.6 channels of processing as they are. The RMC-1+ has three expansion slots and will ship with the Phono + XLR Stereo input expansion card installed in one of its expansion slots. There will be an expansion module to add 4 more speaker channels and another expansion module to add 4 more subwoofer channels which will fill the three available slots and gives us the quoted 11.5.8 output count. It sounds like they are working with Dirac on certification for the two expansion cards and they will be made available based on that and it also sounds like the priority is to complete this certification for the speaker expansion first, then the subwoofer expansion. Finally, it sounds like they haven't shut the door on the capability of replacing the Phono + XLR Stereo input expansion card with one of either of the other two expansion cards in the future but this is neither promised nor a priority at the moment.
To my knowledge, the other questions weren't answered? I may have missed it, answers just haven't been posted yet or there wasn't an opportunity to ask... Either way, I very much appreciate the effort of everyone involved, these capabilities will be known soon enough but just in case it just hasn't been posted yet or someone can point out that I missed it in the thread, I'll drop them again. Maybe @keithl can address these also and/or my presumptive thoughts above.
Is the full compliment of HDMI 2.1b features supported or is it a case of only some of the 2.1b features being supported.
2.1b features I am wondering about are:
Dynamic HDR
Source Based Tone Mapping
Auto Low Latency Mode
Quick Frame Transport
HDMI Cable Power (to power active cables)
It sounds like Variable Refresh Rate and Quick Media Switching is supported but maybe just a verification there?
What does 'enhanced' Atmos decoding mean? What does it do here that couldn't be done before?
Finally, their original soft launch features included being 'music streaming capable', what does that mean?
Thanks again for all the effort guys!
Edit: fixed some spelling and grammar errors

The switching was also much faster. - I didn't hear any popping noises at all either the Dream Theater demo or Damon's. Nobody asked about Australia, but Cathy did mention a couple countries outside the US who have fulfillment centers. It's best to call Emotiva directly with country-specific questions. In the past, the site will add new gear once it's in the house to ship. On the Pi, we didn't ask any details on it. Its sole purpose is to run Dirac, and I don't know if it's easily replaced or not.

anyone took video of the demo, so we can have a gauge of the new switch performance, how fast it switches etc.. I didn't take any videos, but I did count "1-1000, 2-1000..." as Damon switched from input to input. 4K source to 4K source was ~3-4 seconds. 4K to 8K he said they had clocked at ~8. Damon did say they've done timing tests, and it's dependent on cable length and type. They had a very long cable (I want to say 50' from memory), and that ~doubled time vs. a shorter (~1 M) cable. In the Dream Theater demo, they switch from the Zidoo to the Xbox, and it switched quickly enough that I didn't even notice waiting. I wasn't paying attention to the time but it didn't feel like I was waiting for it. Maybe someone else got a video on the switching and can share that. Mark |

Mark Glad to hear that Mark by just switching sources around didn't make you notice it. sounds positive to me. So, the new shipping date is Q1 25? |

Thanks for the great write up, much appreciated! Sorry that I missed your questions...I didn't see your post until today. So, just like the current RMC-1, they currently come with a total of 15 XLR connectors on the back...13 heights, backs, surrounds, FR/FL, Center and 3 that can be R/L Sub or Height + a "center" sub...per the picture in the "gear/demo folder" of 2nd post (pre-pros Plus series pic shows that best). I didn't ask about expansion card availability, but yes - they would be required for more channels. I don't see the output expansion cards on their site, so timing of those would be something to ask Emotiva unless someone got an answer at Emofest they can share. And all Lonnie said about 11.5.8 was that the RMC1+ would "eventually be able to" He didn't cite timing, and we didn't talk any options between 9.1.6 and 11.5.8 We didn't ask details on the 2.1b features, but they did say it's 2.1b compliant. It does include VRR and quick switching per the paragraph starting with "Equipment is..." in the 1st post. I didn't personally ask about the "enhanced" Atmos decoding as I didn't notice that until after the event when I looked at the list of features Dan gave me...maybe someone else got details and can share. And, I don't have any information on the original soft launch features including music streaming. I do recall them talking a potential streaming expansion module "way back", but I've not heard any more about that so it may no longer be in the plans. Worth asking them, but I suspect they'd suggest going for the streamer they are soon to release. Mark |

Glad to hear that Mark by just switching sources around didn't make you notice it. sounds positive to me. So, the new shipping date is Q1 25? Per the first post on timing they said: "Current status is that chips are in for models going out for beta testing, and additional chips will be in early December to enable production. Basic chassis’ are being assembled now and will be finalized once the chips (and also a distribution board for the power supply) arrive in December. Net, if all goes as planned – timing is end of year." So, it's not firm yet, and the steps they laid out have to happen. They are assembling chassis's without the video boards and power distribution boards and boxing them up as they wait for the parts. The picture "RMC-1Plus-d" is one of those built so far. Net, assuming the parts come in on time and the beta test goes well, production completion should be quick. Mark |

Will the changes made to the new amp modules be applied to the Differential Reference Modules used in the DR series of amps? I apologize if this question has been answered.
"Other Miscellaneous
Emotiva is working on new amp modules. These were designed by a young, but experienced amp designer (Dave Goodman) and – among other things – have new resistors in the output stage and more of them. They are better at power handling and are reportedly help the module be stable down to 2 ohms. Lonnie reported performance is great, and work remains on “intelligence” (essentially, operation with their power supplies). They will be able to be used in the current XPA chassis either as a new build or retrofit."

Still higher than I was expecting, and close to triple the current running power, though similar to the AV10 specs. Thats a big jump on upgrade price, I've basically kept it in cupboard for 2 years, what a waste of time. Should've sold it back then, at previous upgrade price I'd have taken a punt on the new model. Very disappointing |

For me its just figures.
Why would a high sample rate and room correction be mutually exclusive for Emotiva processors? The mini DSP can do it. So can some other processors. |

Right now, I am very much looking forward to the new XPA-Gen4 amplifier modules re-designed for 2-ohm stability by the Director of Product Development who has been at Krell for over 31 years! I would certainly find professional reviews on these new Gen4 amplifier modules as very interesting!

Mark Interesting, it surprises me that the Pi is only for Dirac purposes? So it's only moving the Little Black Box internally? Would have thought they used the Pi for other tasks as well. Thx Jim |

Actually, the EDNIB Pi was brought on just for Dirac. But the Pi mounted on the ECC-2 does other things like WiFi, Bluetooth, and Embedded Web Interface.  |
