The 7.1 an along inputs are pure along. There is NO AD/DA conversion. We spent a lot of time and money making sure this is a pristine signal path. Dan, This is one of the biggest reasons I wanted to purchase the XMC-1. The fact that the XMC-1 essentially performs on par with the XSP-1 and the DC-1 makes this prepro unique. Lonnie, Ray and you deserve recognition for the achievement the XMC-1 represents!!

After getting into the minor problems we have seen the TITLE of this is INSIDE TIPs so how about some setup tips from the guys that designed this great piece of gear.

But that is OK because that is my office setup.

Hey Keith, I think we're ready for a second entry in the "Tips" thread. I'm excited to see what else you have for us, and don't want this to die off early like the "Emo-zine" idea. Keep the good work going please!

Thanks .... and sorry for "going dark" there while I finished up the new updated version of the manual. Now that that's in approval, I'll be getting back to posting more goodies Hey Keith, I think we're ready for a second entry in the "Tips" thread. I'm excited to see what else you have for us, and don't want this to die off early like the "Emo-zine" idea. Keep the good work going please!

Wow! I am very impressed that Emotiva implemented the separate EQ on dual-mono subs feature so quickly. It's certainly a very powerful feature, even though making the best use of it may be difficult.
I am just now putting the finishing touches on my bass optimization mini-project. Sadly, my mains responses are such a mess as compared that they undo much of my efforts to tune the subs. That is, until I stuffed the ports on them and set the crossover at 120 Hz. Now it will be interesting to find out how much "directional bass" I hear. So far, I'm hearing less than with the crossover at 80 Hz. I am becoming more convinced that nulls in the response are the cause of directional bass in the lower frequencies. I believe we can perceive the SPL difference of bass between our two ears.
Of course others may have opinions that differ with mine who will be very happy to have the "stereo bass" feature. Flexibility is a wonderful thing. Keep up the good work!

Wow! I am very impressed that Emotiva implemented the separate EQ on dual-mono subs feature so quickly. It is what you see. What I see is that they just implemented joining the bass before passing to separately equalized unrelated (how they call them "stereo") subs. It is not really dual sub bass management (or dual-mono subs as we call it to contradict their "stereo" concept). It's certainly a very powerful feature, even though making the best use of it may be difficult. While this can be made to proper dual-sub bass management manually (by mostly repeating parametric EQ config on both subs) this will lead to totally incorrect BM together with the main XMC-1 feature - the Dirac, if it is implemented the same way. This is not a dual sub bass management and not what was really asked! The comments with reasoning about the need to EQ both (pre-integrated) subs as a unit was to date ignored by Emotiva. Something tells me I'll need to raise the BM question again once Dirac is released. I do not want to have a choice between a dual sub BM and Dirac. And manual parametric EQ, while is very good on XMC-1, is not an option if the time-domain correction of the Dirac is on another side of the equation...

So if I understand you correctly you want to know how DIRAC handles the .2 sub setup on the XMC, correct? The answer to that question may or may not lead to other questions but we should reserve comment until the DIRAC question is first answered. So Keith, how does DIRAC handle the XMC dual sub outs? Are they EQ'd independently or as a unit and who does that affect the current options available when using DIRAC? This answer most likely should be in another thread.

So if I understand you correctly you want to know how DIRAC handles the .2 sub setup on the XMC, correct? The issue is that we need it to act as .1, not .2. We should be able to set the distance and gain independently, and then EQ (or DRC) them as 1 unit.

We should be able to set the distance and gain independently, and then EQ (or DRC) them as 1 unit. As the Dirac is not a simple parametric EQ but a full FIR filter correcting time and amplitude (yes I know that might be over-simplified), how would you independently set distance and trim for the 2 subs without calculating 2 filters? If the XMC-1 computed 2 signals, one for sub with a different distance and trim, then you would still need 2 Dirac filters because the inputs are not the same... If you applied the distance and trim after Dirac, then you would be corrupting the Dirac correction... Guessing at the types of scenarios you are considering, perhaps you could get where you want with 2 independent Dirac subwoofer filters by altering the Dirac curve to raise the target frequencies so that a frequency in a null on one sub gets a higher level from the one that is not in a null - this assumes that Dirac's analysis of the data does not already attempt to consider such things...

See this post from Flavio, who is a Dirac employee: emotivalounge.proboards.com/post/664789/threadIf you have more thoughts or questions about Dirac and bass management, please post them in that thread. There are some very knowledgable people trying to think through this in that thread.

Even on the top of the page I cant see how to subscribe to a thread??? Go to Profile Edit Profile Click the tab called Notifications Choose Email when a Bookmark is updated. Then Save the Notification settings. Now when you bookmark a thread you'll get an email. The dropdown menu where it says Actions is where you'll find the option to Bookmark.

Keith I did the update a few days ago ( note, it would be nice to notify owners by email, some of us do not live on the web site anyway you were talking about some problems with the dual monitors. Mine when I start to exit, I get a load pop through the left side when I am on Levels in the setup menu and go back from whatever speaker you were setting the levels to Levels on the menu there is a pause a that point and then when the music start back up the Left sub really thumbs with what sounds like 50 HZ or lower. I have to make sure before even starting into setup on the main menu to have the volume below -30. Also while the digital noise between tracks on the Oppo 103 is mostly gone it is still in the back ground some of the time and if I use Pandora it is there between every song. Forgot , I am not using the PEQ yet until I get the problems ironed out.

This is not so much an "inside tip" but more an "outside tip"! In case some of you are looking for a serial number for your XMC-1, it can be found on one of the outside corners of the outer box. I had a feeling someone may be looking for the number!

I had a feeling someone may be looking for the number! So is the number on the inside of the case or someone just forgot to stamp the backside? Edit: is this the first product that voids the warranty if you dispose of the box???,,,,he,,,,,,he,,,,,,

However as with any gear, it behooves the customer to record it somewhere safe. I never dispose of any boxes just in case (that really helps if one decides to sell/return/ship the unit).

Sage advice hemster! These were the jokes,,,he,,,he,,,, but really, I have a room full of boxes, I'm a little twisted. Being that I just got the 100s and the boxes were damaged I've asked them to replace them because they were damaged in delivery from the retailer to me. You never know when you'll need the boxes but some day they, the 100s, will be moved again and the safest way to do that is with the boxes made for the product. Much easier to get the boxes replaced now then later when I need them and not when they would get around to sending them and most likely charge me for them. Get more with sugar! I've asked nicely and pointed out my need and reason, they said it would be no problem. Very kind of them and I'm greatful.

I had a feeling someone may be looking for the number! What an odd decision not to stamp them somewhere on the body. Are you, by any chance, monitoring a certain thread on AVS where this might have come up?
