Dual subs: Could try dual mono or one as LFE and the other Mono - the way the new algorythm works you may be equally good either way. Lonnie??

Hi question for those who are running 2 subwoofers. Which 2 are you using? Right left or center? I also see the choice is mono or dual mono? Any thoughts or which one I should choose,? Any help would be greatly appreciated. Thanks Joe From page 71 of the 'preliminary' manual:
"The RMC-1 supports up to three subwoofers; each of which receives the same monaural LFE and low frequency content. The left, right, and center designations are provided strictly to aid in identifying each subwoofer by connection and room location." In other words, it doesn't matter. I have four subs connected to the center sub output via a pair of two channel amps daisy chained. Each amp drives two subs. But each sub receives the same mono signal.
Hopefully there will be an add on RMC-1 module and/or a future Dirac option to address multiple subs

Ok if each sub receives the same mono sign why does the left and right have the option of dual mono along with mono? The center only has the option of mono?

Also, much more flexability, and I've seen that works well with DIRAC anyway. We don't know if and when EMOTIVA will release a better multi-sub solution than they currently have.

That will incorporate the LFE and summed bass signals. Now if you were running three subs you could do one for LFE only and the other two for dual mono. Lonnie

Lonnie lonnie , are you stating that my 16’ X 19’ X 8’ theater needs another duel 15”” driver sub? 🤯

Stereo subs in a 2.2 configuration isn't supported? Is it road-mapped? I'm hoping the RMC's bass management gets another overhaul because 11.5.8 isn't really 11.5.8 without flexible bass management. Here is a snippet from Lyngdorf's MP-50 (supports 7.5.4/5.5.6/9.5.2) manual. Lyngdorf's bass management flexibility pales in comparison to StormAudio. Step up again into a Trinnov I have yet to encounter a scenario which cannot be implemented. I have stereo subs (folded horns) in the front for bass management (125Hz xover) and separate subs for LFE. I could always use an external DSP [w/Front L&R set Large] to accomplish but such a workaround (extra DA/AD conversions) is far from ideal.

Correct me if I’m wrong, but on the production and post-production side, dual-mono is two discreet (same or different) signals sans panning.
Since bass is non-directional and panning is moot, could they be referring to stereo as dual-mono?

From the RMC-1 Manual currently posted: On the otherhand, the XMC-1 does provide Stereo to the subs. From the XMC-1 Manual for comparison: edit: I wonder if the latest firmware with the super dooper subwoofer sauce changes things such that the subs CAN be configured in true stereo ??

From the RMC-1 Manual currently posted: View AttachmentOn the otherhand, the XMC-1 does provide Stereo to the subs. From the XMC-1 Manual for comparison: View AttachmentAgain it’s 6 of one, half dozen of the other. Sending low freq content form the left and right channels can be thought of as stereo, even though it’s technically only dual-mono. I think it’s a semantics issue that is the same result no matter how you (or Emotiva) say it.

I have two pairs of subs on my XMC-1, a front pair and a rear pair. After trying all the different schemes, I run the two pairs as a pair of dual-mono subs, equivalent to running two subs as dual-mono. Bearing in mind the RMC-1 may work differently, using dual-mono lets the processor set amplitude (gain) and delay (phase) independently (and Dirac Live treats them as two subs) so it will handle the integration for you. If you use mono, you must integrate them by adjusting phase/delay and levels for each sub yourself, manually or by using a miniDSP, Behringer, dbx, or similar processing unit.

Sub discussion makes me dizzy. I have been sucked down the sub rabbit hole too many times. Hook them up in the best place you can for your room, balance them as well as you can to get the sound YOU like and move on. That rabbit hole will get you. You have been warned. So, what have people noticed good and bad about the new firmware 1.5?

Here is the statement I remembered Jun 18, 2019 10:13:07 GMT -4 KeithL said: Bass management is what you're using when you set a speaker to small and assign it a crossover. The RMC-1 itself currently has bass management that complies with Dolby's standards for Atmos - which means a single subwoofer channel. On the RMC-1 you can assign one, two, or three subs to that channel. In the future we may add the option for stereo subwoofers or more advanced options.

Trying to avoid doing a cold start reset (unplug from wall ect) to get RMC-1 to pass EDID info from sink to source when going from 4K HDR movie Justice League (using JVC600 4k HDR projector) to 4K DV Justice League (using 4k DV/HDR LG tv). Maybe a Hot Connect/Sink cmd would do this and avoid all this powering down, unplugging and powering back up. Don't mind waiting for all the devices to sync up. Movie: 4K Justice League (4kDV or 4kHDR, ATMOS or neural:X) Config: (disc)OPPO203/Main_V/A ---> Input1/RMC-1 RMC-1/Output1 --->---> JVC600 RMC-1/Output2 ---> LG_C8_77"_OLED
Have you tried completely unplugging the HDMI of each sink device and see if the issue remains for each one individually? Lonnie Yes. Each Output/sink works individually with no issues ... worse case is there is only a sync issue present and this is corrected by shifting RMC-1 inputs 1 > 3 >1 to trigger a hot plug connect ... like you said. Why does the other "inactive" output affect the active output? Are there any restrictions on how to use RMC-1 outputs? I've normally used output 2 for LG C* 77" OLED and output 1 for JVC600 projector ... unless in "audio only" mode.

I did test my projector again today with firmware 1.5. It still behaves the same, resyncing all the time.. Then I tried to change settings in my bluray player. Instead of relying that the hdmi sync being right I set the output resolution to 1080p/24. Also turned off Dolby Vision and HDR10. I put in a standard bluray disc, checked that it got both input and output in Rec709/sdr, 1080p/24 and everything else correct. It still did the resyncs all the time. Then I removed the Sony ZD9 from the output 2 on RMC. Then no more resyncing, I sat for almost one hour and a half testing different discs. Even some 4k disc that I scaled down to rec709 and 1080p. Everything worked fine. This worked fine on my previous AVR.. So is there something that RMC checks for that other manufacturers don’t that make it behave like this? Something that I have reacted to, and my friend visisting also, is that everytime I press pause RMC let go of audio sync. For example while playing a 4k movie with atmos, then pressing pause on the bluray player makes RMC go to PCM. Why does it do that? Yes if I press stop, but it should keep it in pause IMO. From what you describe it sounds like your Dish box is failing to "notice" that the RMC-1 has turned on... (So, it has "gone to sleep", shut off its output, and not noticed that it should turn the output back on because the RMC-1 is "there" again.)
However.....
"Maybe there’s a problem with the Sony TV hogging the HDMI sync somehow? Even though it’s in standby.." This is also a distinct possibility. HDMI devices remain "visible" to other HDMI devices, even when they're in Standby, even when they're off, and even when they're unplugged from the AC line. (An HDMI device actually sends power down the HDMI connection so it can read the status of the device at the other end - even if its off.) We have absolutely seen situations where a certain HDMI device causes problems - even when it's turned off - or ONLY when it's turned off. The easy way to rule this out is to physically unplug the HDMI cable between that TV and the RMC-1 and see if the problem goes away.
While much much better generally there’s still much work to do until you reach other manufacturers level. Example, I have problem syncing with my parabol dish receiver. when I start it I usually get only picture, no sound at all. No matter of restarting any devices or changing order of start help. If RMC is on and I pull the plug of the dish receiver and reconnect it will sync picture and sound. It never works from standby. This has actually become worse since 1.4. Also the problem with two different output units. I have serious problems using my projector, as reported in earlier posts. And no problem at all from my TV. This with 1080p sources that should work for both outputs. If this has to do with output 1 or 2 problems, problems with devices that has different HDMI standard, resolution or whatever it still doesn’t work as it should. Not even close. As I said, I can’t even start my projector for a minute before resyncs start. It even resynced before outputting video from the bluray player, other than its logo. Maybe there’s a problem with the Sony TV hogging the HDMI sync somehow? Even though it’s in standby.. Same cable and everything worked flawlessly on Pioneer SC-LX801.

I apologize if you answered this before - but are you using the TV and projector at the same time? You mention that you disconnected the TV and the PJ works fine, so I am wondering if you are trying to use them at the same time. Mark

Could your AVR have done video processing or was it also just pass through? That would account for differences in the way the two handle dual displays.
