Looking back at old posts, it sounded like both the UMC and XMC were going to use a single Cirrus dual core DSP chip. But the way it is described
"Twin Cirrus® 32 bit dual core DSP’s for uncompromised high resolution HD audio decoding"
it sounds like there are TWO dual core chipset in the design. Am I reading this right? If correct, that would mean 4 seperate core processors on two chipsets.

First post here but joined and have surfed for a while - original owner of DMC-1...
Couple of questions for Dan/Lonnie/Dann –
These questions were mentioned to some extent by nemesis in the “Aren't we supposed to get XMC-1 news this week” thread, but I don’t recall seeing any clarification?
Will there be side-axis channels on the UMC/XMC and if so will XLR connection be included?
It was indicated that there will be 3 sub outputs on the XMC-1 –
Will these outputs allow various configurations? Most interested in capabilities for allowing a stereo pair for true full range mains and 1 LFE?
Since there is going to be a lot of processing power, will these “extra” outputs (side-axis and additional sub outputs) possibly be fully configurable (i.e., create their contents from any or all of the other 7.1 channels, and also adjust their bandwidth, level, and delay)?
Is there any consideration of a computer interface for configuration/setup of the processor that would allow saving and loading of different system configurations as desired?
Thanks,
Eric

I've got a few questions, and comments as well. I'm in the LCD TV/projector camp so those 2 HDMI outs are a requirement for me. I'd like to make sure the output resolution can be set independently for each, one 720p and one 1080p? It's not relevant to me if they're both outputting at the same time. Is there going to be a DMC replacement? I was originally going for the DMC replacement, but if there's not going to be one, this XMC appears to cover everything I need.... and then some.  Would it be possible to have some kind of debug/info screen that shows us the sample rate and bit depth of the source? I'm always concerned that my xbox and some DVD players are only spitting out 48khz / 24 bits when playing a CD, which should be 44.1khz / 16 bits. It'd be a great way for some of us to double-check that our sources aren't doing a conversion on us. This would also help if we were setting up a computer as an AV client and wanted to make sure a conversion wasn't happening there as well. I wouldn't mind some clarification on what type of streaming you're looking into. I ripped all my CDs to FLAC a couple years ago and stream them using XBMC off an xbox. As you can imagine, I'd love to have a source that is better than an xbox. However, I'm pretty picky as to the methodology. I don't use Apple products, or anything that would cause vendor lock-in. I guess XBMC works for me since it uses a samba share, which doesn't require any additional software to be installed on the computer. Dave |

This would also help if we were setting up a computer as an AV client and wanted to make sure a conversion wasn't happening there as well. I like this idea also (the more info the better) and would like to see it in the main display. My Onkyo can do this. I wouldn't mind some clarification on what type of streaming you're looking into.

Dave Would also like more info on what is being considered for streaming. I have all Apple Lossless and to decode it would likely require a licensing fee to Apple (unlike FLAC). Also would love to see (HD) video streaming. While this may seem a little exotic at this time it's likely to become more of a standard. |

Did I miss a phono input and HDRadio. Please says I does that would be very very nice.

Wow, those are great specs. 8 HDMI inputs is amazing. This really is going to be a flagship product. I'm very glad I'm on the pre-order list...
I don't currently need the second video zone, but it's great to have just in case. The main benefits to me are the DACs and the balanced outputs. Those, alone, justify the upcharge over the UMC-1.

Question on the Quadruple bass manager.
Is this a like a standard 40-160hz adjustable crossover found on most plate amps?
I was hoping that there might also be a subsonic filter, i.e. selectable high pass in the 15hz and above range.
Maybe this will be on the Emo subs, but was hoping to have it on the XMC.
I was looking at getting a Reckhorn B1 bass manager just for the adjustable e subsonic filter.
I use a ep2500, and get overexcursion problems from ultra low bass. the EP2500 has a standard 35hz cut, on/off, which is too high, and probably not a steep enough cutoff.
Any thoughts

Thank you very much for the update Lonnie.
Looks like everything is covered as far as features I was hoping for, with the exception of one. The ability to stream video & audio from a media server and hopefully the INTERNET.
Certainly looks like I may end up with a new Emo processor after all.
Also a projected price would be nice.
The XMC-1 sounds like its going to be a real STUD!
Man... reading the features list gave me a woody. ;D

One question, which AD DAC's will be used?  Will it be the AD1955's? Or something similar? I'm wondering this too... What's the configuration? Is it a single multichannel DAC like UMC or multiple Stereo DACs? It seems my choice between UMC and XMC has been picked for me with this info, but I'd like a little more information on the DACs and other sonic upgrades from UMC... mainly out of curiosity. A bit bummed that I am going to have to wait even longer now! Though, it's not a big deal... I need to get a laptop this month, so having some buffer between new toys never hurts |

LCSeminole: Thanks for the info on the DSD, didnt know about that. So basically with DSD if you have a player with SACD capability all you really need is just an HDMI connection, with that you got your video up to 1080p, good for digital audio with the new formats, and good for SACD no need for analog connections. Sounds good, thanks again. Actually as far as I know, not all SACD players can output DSD over HDMI. I know OPPO's do, don't have one, but just learned it surfing around. Some can decode and output LPCM over HDMI, but I guess some people don't like this. I wouldn't know as I'm out of the SACD loop, maybe some SACD users could chime in an enlighten you more. Just my two cents. |

Just my two cents. DSD over HDMI is the SACD equivalent of the digital PCM output over coax/optical from CD players. Not all SACD players can do this - my Denon 3930Ci can't. DSD was added to the HDMI spec in revision 1.2, so I had assumed that any device that is HDMI 1.3 compatible supports it, but I'm not positive. |

The XMC-1 sounds like its going to be a real STUD! Man... reading the features list gave me a woody. ;D just using this as an example not wanting to call out anyone in particular out...with that said... I dont understand why the XMC should have wireless streaming capabilities? It reminds me of the old saying "Jack of all trades, Master of none". I guess to each there own but if streaming is a requirement, there are most likely dedicated media streamers already available that fit the bill. Why include it in the XMC when you can get one now that probably does it better (obviously no ones tried it, but in my experience it always bears out that a dedicated something is usually better than a multi-tasking something; if you follow) Just my .02 |

This looks like a truly giant-killing piece of equipment! Great job, Emotiva! I'm really looking forward to a "buy it now" button next to this one!
I asked this question elsewhere on the forums, but maybe this is a better place for it.
I have an MMC-1 now, with an IPS amp that I use in a bi-amp configuration. I also have a two channel setup in an adjoining area. I'm thinking that it would be awesome to have my turntable, possibly an Emo CD player, and other two channel gear, connected to the XMC. I could use it in the main listening area, but most times would prefer to listen to two channel music in the second zone. This way I could use the same sources in both zones, or in only one zone. In fact, I can probably do this with the MMC, but haven't tried yet.
So, here is my question. Given that the second zone will most likely only be a two-channel zone, will the XMC have a pure analog path through to that second zone? I could get an RPA-2 to drive the second zone speakers. If it's a pure analog path, then I think the sound quality would be awesome with it set up this way. The only other issue would be a separate zone for the remote, such that when I am in the second zone, I can adjust the volume of the emotiva from the second zone, independent of the first zone.
Lonnie, any comments on this? Does anyone have thoughts on how this may work in XMC?

From my understanding, the 1.2 (and 1.3) spec supports DSD, but it doesn't require it, which is why you don't see all 1.2 or 1.3 players supporting DSD.
