Mostly true.... you need eARC to get true hi-res multi-channel or Atmos.
(Technically you CAN get Atmos via DD+ with ARC... which would give you all the Atmos channels with high-quality compressed audio... but we've never seen a TV that offers that option.)
ARC doesnt have enough bandwich for hires/atmos (( |

I have had my xmc2 for almost 2 years, I came from an xmc1. I didn’t have many issues with the xmc1 but the xmc2 has never sounded great, muddy bass or zero bass, tried Dirac curves, 3 different Harmen curves, storm audio curves, Nad target curves, I could never get it to sound right, even after getting a reseller to do the Dirac calibration. “Even he said he’s never experienced so many issues in processor while doing a simple Dirac calibration.” Laggy remote /osd, HDMI switching issues, losing 1 out of 4 atmos speaker when level matching, then a loud pop sound will occur when it turns back on during playback, Audible noises with each adjustment of the volume at higher levels -20+…… I’m almost at my limit. Please tell me there is an major update coming soon to fix the bass management. The other option is to wait for the Anthem AVM70 to come on sale and jump ship and I really don’t want to as I’ve been an emotiva fan for many years now. Just because the emotiva processors are cheaper than their competitors with similar specs doesn’t mean you can release a half baked unit and then take so many years to not even get it right…. I almost feel cheated Keith, we feel very much the same way. I think we have both come to this from the same direction. I bought an XMC-1 and despite a few small issue that were either resolved over time, or circumvented by some other means, I was happy with it. When the XMC-2 and the RMC series were introduced I thought "great - here's the v2.0 product with all the issues oof the v1.0 fixed, along with refinements and greater control" - oh boy, was I wrong. From the day I received my RMC-1L I've had nothing but disappointment. I used to avidly recommend Emotiva products. That stopped pretty quickly. I just couldn't recommend something that had been giving me so much trouble, across so many basic functionality issues. The HDMI handshake issues have meant that I have only watched one or two BluRays for six months. It's just such a pain to make the BluRay player connect, involving multiple restarts and a very specific reboot order, my wife just gave up. We receive 150-200 screeners a year. I won an Emmy in 2018, so I'm on the voting panel for the Television academy as well as BAFA (the British society) so I have to watch an awful lot of stuff. These days we opt for the digital screeners. If we get a BluRay that isn't available as a screener, I'll try to get it set up, allowing an hour or so to go through the correct sequence, hoping that the BluRay player will connect. Yet, like you, I persist with my RMC1-L. Though I keep my eyes open for another AVP that will suit my needs. If I'd have found one that offers me what the Emotiva has promised, I might have bailed already. Though instead I just live in perpetual hope that, at some point, this AVP will eventually work as described when it was released. I hope that Emotiva solve these issues and send a unit to Amir at The Audio Science Review to independently test it, then address whatever issues he exposes. This will give Emotiva back some of the credibility it has lost with the people I know who have decent home theatre setups. Because currently they are scared off by people like me who have been tortured by the experience of trying to make the RMC simply change inputs without causing it to melt down. Like you I have used Emotiva products for years. Starting with my XMC-1 I've bought 7 other products from them and recommended at least 5 other people to use their products. The American Film Institute in Hollywood has four Emotiva processors in their screening rooms on my recommendation as I lecture in filmmaking there. It's not that I haven't been the attentive and loyal customer. But my disaffection with the RMC-1L is cooing to a head. If I can't get this all resolved by August, before the awards season deluge begins, I'm going to have to cut my losses and jump ship too. Question is, what is there to replace it? First off, congrats on winning an Emmy, that's pretty awesome! It's always interesting to get a peek behind the curtain to see what those in the industry use as far as processors and other equipment. I'm in pretty much the same boat as I've said on here before, I would really like to see these annoying issues resolved and the major point for me is the addition of DLBC. I know it's been discussed many times so I won't go into it too much further, but it was disappointing to say to the least to hear that there is no time frame to get this added, which tells me that it is not in development and will not be ready for quite some time. There's not really any perfect 16 channel processor out there but some are starting to take shape and if they fix the major issues would be solid contenders to jump ship to. Personally, the two in my price range would probably be the Monoprice HTP-1 and the JBL SDP-55. But again, neither of them are without their own issues. IF they manage to get further firmware updates (both companies have been silent on that for some time) then that will instill confidence in me that they are viable alternatives. At this point, even with their own issues, I'm considering them at some point in the next year since they have DLBC. The other issues are just trade offs compared to the XMC-2. And honestly those issues may be easier to live with than the ones with the XMC-2. I will give credit, I just upgraded from a TV to a JVC RS440 projector, I expect to have a host of issues, but so far it's actually handled it really well. I did purchase a fiber optic high bandwidth HDMI cable, so I'm not sure if that has helped or if it would have handled it the same way with copper. Either way, I've only had a couple handshake issues since moving over to it which surprised me. May be worth looking into to see if that helps? |

Either way, I've only had a couple handshake issues since moving over to it which surprised me. May be worth looking into to see if that helps? Keith, Thanks for that. I’ve had a 30 year career working as a cinematographer shooting movies, tv shows and TVCs. My Emmy was actually awarded for my “sideline” work developing tools for filmmakers. My key product is a directors viewfinder system used by filmmakers the world over, from Spielberg to budding film students. Even though I’ve gathered other awards as a filmmaker, it’s my work developing equipment and software for use by my filmmaking heroes that brings me the most pride. Consequently I’m well aware of the difficulties in designing software and hardware in general. This of course makes me deeply sympathetic to the plight of Emotiva. I truly believe they are a decent company run by people who are at pains to address the shortcomings of their products, while innovating both at the technical level and in their direct to consumer business model. I remain a fan of them. I’ve never had anything but respect for them and feel as though they have offered support to the best of their capability. The fact that these basic issues with HDMI connectivity and the delays in implementing features promised from the outset persist after two years stretch the goodwill I still hold for them. Like you I’m still optimistic for a satisfactory outcome to this situation. Beyond that, I’m still hoping to be dazzled by the innovative approach from a clearly talented group of engineers. I know these posts are monitored by Emotiva. I hope they understand the affinity we feel for their product and for them as people. I hope they dig themselves out of this pothole. |

ARC doesnt have enough bandwich for hires/atmos (( Keith, this is what I use, with LG OLED TV, AppleTV plus app on TV and Disney Plus, Amazon Prime Video, connected HDMI ARC. Atmos contents succsfully send to my RMC-1L and it shows imcoming stream is DD+ and has Atmos metadata on it. RMC-1L nicely play DD+ Atmos contents from TV via ARC. Only thing is that Netflix does not. It is really pain in the a**, under 1K USD basic receivers from Denon, Marantz, Onkyo and Yamaha, even under 100USD soundbar can decode DD+ Atmos from TV Netflix app but not Emotiva. I asked many times here and Emotiva customer support center but no answer at all. I don't know why you said "we've never seen a TV that offers that option". ![]() This picture shows my RMC-1L while playing Atmos contents from Amazon Prime Video app on my LG TV through ARC connection.  |

Some apps/devices insist on using multichannel PCM with Atmos layered on top which is completely incompatible with standard ARC (Requires EARC).

I've purchased Apple TV 6th generation 4K today, finally!!!! I have had headache for ages because of the stupid ARC and TV internal apps, especially Netflix. Netflix can't detect RMC-1 as ATMOS capable deivce, so ATMOS never showed up. At 15 of Jun, 2 days ago, Disney plus app had been updated, and it also can't detect RMC-1 as ATMOS device anymore, same as Netflix. I was frustrated, and think, why am I struggle with this sh** apps? So I accept suggestion from everyone here, buy on Apple TV box. ....and.... You know what? I think that I am really idiot. Why I never search goolge for "Netflix Atmos issue from Apple TV" before spend my money to Apple?  ?? Ok, Disney Plus, Apple TV plus, Amazon Prime Video, nice Atmos sign showed up! And it is not DD+ Atmos. It shows TrueHD Atmos! Bingo!!! HOWEVER.... Netflix, this fu**ing Netflix, no Atmos at all. All movies which I know they are Atmos movies, shows as "5.1" only. So I was dumb, and search this issues, all same problem as mine, are all over Reddit, Apple Support, Netflix Support, etc, etc. Why it is like this? What Netflix did on their app??? How about shield TV and XBOX??? Even if they are ok, I will not buy it again... |

I just did some research, there is bunch of people complaining this issues on Apple support... There may be a cable issue... change cable can fix it, or set 1080p, the Netflix shows Atmos... after change 4K, Atmos fixed.... I haven't had a enough time to test all of solutions, but I will change HDMI cable and test it today. Will connect to TV directly, it should be no problem. Whatever, I think that it is not a issue for Emotiva. Even though, why other apps (Disney, Amazon) works perfectly? No idea....  |

ATMOS will become deactivated and needs to be toggled on/off in the Audio system menu for it to work. Before I watch anything, I go into the setup menu and check the Audio options, if ATMOS isn't listed...I do the toggle or reboot. |

I had the same issues with my Amazon FireTV stick. No Atmos and it kept losing connection. Went with a Roku and Atmos is working great.

I assume you know, but it needs to be said, that you need the “Premium” Netflix plan to get both 4K/UHD AND Atmos. The Standard plan only delivers HD & 5.1. |

All the talk about level setting got me thinking that it’s been a while since I checked mine, and I wanted to do a comparison of internal vs external tones (I’d also scooted the sofa forward a little bit last time we cleaned the carpet — more ‘immersive’ 🙂). This is just another data point in the discussion. My measurements are taken with a UMIK-1 connected USB-C to an iPad Pro 11G2 / iPadOS 15.5, running AudioTools 15.5.9, I use the SPL Pro Digital Sound Level Meter function (dBC slow). BTW, AudioTools now runs on M1 based Macs like my MacBook Pro 14 at no additional cost. I didn’t notice a new version 15.6.x had come out with “ NEW! Now includes the HAA Home and Pro Installer Home Theater Testing modules (iPad Only)”, I’m checking that out today. I first reset my RMC-1 to factory defaults, then reloaded a backup that had my inputs, triggers, speaker size, levels, crossover, and distance, but no Dirac. I checked and tweaked my distances with an Amazon laser tape, because of the sofa move they all changed at least a few inches, some an entire foot or so. I then setup the UMIK at the MLP, with the iPad behind and out of the measurement path. Next I ran the RMC’s Internal Levels at Medium for all of my 7.2.4 speakers, I use the center channel for reference, on my system this produces a level of about 78 dBC SPL. All the speakers needed slight tweaking, typically 0.5 to 1 dB, some 1.5 maybe a 2, none of them were drastically off, but enough to warrant the effort. For the record, my two subs are connected L/R and configured Dual Mono, they are setup symmetrically to the MLP, behind and outside of the L/Rs, all my speakers are set to small, base layer crossed at 80Hz, heights at 100. Then I setup for external tones (I have not done this in possibly two years). I use the Dolby Labs files for Atmos system setup, there are individual files for each system configuration, I used the 7.1.4. I play these MP4 files from a USB Stick inserted in my Oppo UDP-203, then on via HDMI to the RMC-1 set for External levels. Generally the SPL was about 2dB lower, but the levels for each speaker were within 1 dB of the internal measurements … until I got to the subwoofers. First, because the Dolby tests produce a “.1” signal, both subwoofers are active, unlike the internal tones which test each speaker separately. One would expect a 3 dB increase because of this, but I measured a 12-13 dB increase. I don’t remember this being the case the last time I made these measurements (but I’m trying not to insist that my memory is as good as it used to be 😳). My first suspicion was “the G3P Elevated BM & LFE Issue” (thank you ttocs and marcl for your considerable work on this), but I don’t know if the numbers pencil out. I repeated the test with the same results (the Dolby test is a bit tedious because it’s essentially a video playing and unless you fast forward and rewind you have about 3 min of noise on each speaker). The second time I noticed that the subwoofers are playing along with all of the channels, I haven’t noticed this before either, but it may be ‘normal’ for external tests. The RMC-1 is just processing the signal being sent, and Dolby is sending a full range signal. I should probably go back and unplug my subs, before measuring again to see if their level is significantly affecting the measurements. Or possibly these aren’t useful files for this method. So far the only listening of the system were a few episodes of “Orville” steamed on TV and Amazon Prime (we’re rewatching the originals before starting the new season 🛸). With the 5.1 audio track through the DSU, the surrounds were definitely more evident and balanced, so the distance and level tweaking payed off. Whatever my bass is doing does not sound abnormal to me (but I may be getting less critical as I forget why I care 😮 just kidding, I do care, I just haven’t pursued it). Oh, I actually first loaded this firmware backup a couple weeks ago, so I’ve been running without Dirac since then; I’m waiting for some amp changes next week before I remeasure and reload, so my listening tests are s and s So another piece of data for the soup 🥣 |

I've fixed Apple TV Netflix Atmos issue. I've followed suggestion which some user posted on reddit. First, set Apple TV 1080p SDR mode. On this point, Netflix app still not showed "ATMOS" badge on contents but ATMOS will kick in on receiver when playing it. Still movies or series not showing ATMOS badge but 5.1 Go to setting, set video to 4K SDR, YBCR 4.2.0, match dynamic range ON, match frame rate ON. Go to Netflix, now all ATMOS badges will be appear on movies and series info, all should be fixed. It is weird, change to 1080p from 4K, and return to 4K again do the trick, it fixes some handshake process and.... how??? Of course it doesn't matter as long as that fixes last until my device's lifetime finish.  |

Of course it doesn't matter as long as that fixes last until my device's lifetime finish. I’ve had my own intermittent issues with audio dropouts when playing Atmos content on ATV4k. This has occurred across Emotiva XMC-2, Denon and Arcam AVRs, so it cant be the AVRs fault. Mostly Netflix but sometimes Apple TV+ and other apps and only on Atmos content. I finally found a solution on an AVS Forum to change the ATV4k from wired to wi-fi. I am amazed that this has eliminated the audio dropouts and I am at a total loss to understand why this fixes the problem. Every other device has always worked better with hard wired network connection. Go figure. So I think that the ATV4k is a work (hopefully) in progress, although it really should have been bullet proof by now, Apple needs to start caring more about this platform. |

So far the only listening of the system were a few episodes of “Orville” steamed on TV and Amazon Prime (we’re rewatching the originals before starting the new season 🛸). With the 5.1 audio track through the DSU, the surrounds were definitely more evident and balanced, so the distance and level tweaking payed off. Whatever my bass is doing does not sound abnormal to me (but I may be getting less critical as I forget why I care 😮 just kidding, I do care, I just haven’t pursued it). Oh, I actually first loaded this firmware backup a couple weeks ago, so I’ve been running without Dirac since then; I’m waiting for some amp changes next week before I remeasure and reload, so my listening tests are s and s So another piece of data for the soup 🥣 There was an issue with the Dolby disc that made me stop using it. I'm going to be out until late tonight, but I'll check tonight to refresh my memory about this. I too had huge bass - but only with certain tracks on that disc. Stay tuned. |

Then I setup for external tones (I have not done this in possibly two years). I use the Dolby Labs files for Atmos system setup, there are individual files for each system configuration, I used the 7.1.4. I play these MP4 files from a USB Stick inserted in my Oppo UDP-203, then on via HDMI to the RMC-1 set for External levels. Generally the SPL was about 2dB lower, but the levels for each speaker were within 1 dB of the internal measurements … until I got to the subwoofers. First, because the Dolby tests produce a “.1” signal, both subwoofers are active, unlike the internal tones which test each speaker separately. One would expect a 3 dB increase because of this, but I measured a 12-13 dB increase. I don’t remember this being the case the last time I made these measurements (but I’m trying not to insist that my memory is as good as it used to be 😳). My first suspicion was “the G3P Elevated BM & LFE Issue” (thank you ttocs and marcl for your considerable work on this), but I don’t know if the numbers pencil out. I repeated the test with the same results (the Dolby test is a bit tedious because it’s essentially a video playing and unless you fast forward and rewind you have about 3 min of noise on each speaker). The second time I noticed that the subwoofers are playing along with all of the channels, I haven’t noticed this before either, but it may be ‘normal’ for external tests. The RMC-1 is just processing the signal being sent, and Dolby is sending a full range signal. I should probably go back and unplug my subs, before measuring again to see if their level is significantly affecting the measurements. Or possibly these aren’t useful files for this method.

Stay tuned. + audioHTIT regarding the subs, if I'm reading correctly you should expect +10db for the LFE boost since the processor sees it as a .1, and +3 for there being two subs. So I think 13db is reasonable. But of course how the two subs interact to cancel or reinforce some modes could alter that. Make sense? |

Yes, I had thought that a possibility, but couldn’t remember when the +10 was to be considered, and the +13 seemed to fit right in. Thank you! |

I actually downloaded these files off their site years ago, but they’ve since disappeared, I didn’t know they were available on disk. If marcl’s explanation makes sense, what I’m seeing could be normal. As I mentioned, the final result doesn’t sound bass heavy, but I’m interested in what you find. |

Does anyone have recommendations for network streamers for airplay/spotify for the RMC-1 or any update on the network cards that may support this built-in? If I have an external solution, is there a way to connect this so that it will automatically switch on the RMC-1 once I send music to the streaming device? Thanks.
