OK, I thought the crossovers were still applied in the analog only domain. So scratch that part. Come to think of it, how would an incoming two channel signal be applied. Is there an analog only mode that can be applied (as opposed to using the 8 channel inputs)? Is it that full range speakers are required for straight 2 channel analog? That would make some sense.

My take on it is exactly that. Use the same EQ levels for all channels for frequencies below the crossover unless there is a particular channel that you would like to run hot or cold for some reason. If, on the other hand, you have an external equalizer, then leave all frequencies flat and adjust via the external equalizer.

You run into a problem with the LFE channel though, it doesn't have the same EQ bands, so you cant match the bass being redirected from your mains with the bass from the actual LFE channel. I'm not sure how noticeable that would be in practice, but its not really ideal that's for sure

I'm not sure how noticeable that would be in practice, but its not really ideal that's for sure Good point nickwin - The same number of bands in the sub range for both the sub and main channel EQs would be rad. You should submit that as a feature request. (if you haven't already) I guess I'm lucky and only need to tame a bump at around thirty cycles so the number of bands for the mains should do. One nice thing about this is that if I wanna make the movies sound more 'exciting' while leaving the two channel response correct for a more musical presentation, this dueling EQ setup lets me do this without any fiddling before switching sources.

This is all a very interesting discussion. For me, I am just really glad that in stereo + sub mode that there is bass MGMT as Lonnie has described. It sounds good enough for me, and the multi-channel EQ appears to be awesome for all channels, including 0.1 channel.
In the finer nuances being kicked around re. matching what frequencies get EQ'd on stereo mode vs. what are available on a per-speaker basis in multi-channel mode...that's all a very interesting theoretical discussion.
But, I really have to wonder, can any of the subtle aspects that might result from what many are describing as ideal be even remotely audible?
I'm thinking that my ears (47 year old ones) can tell if bass is there or not, if it's too loud or not, and if it's clear/warm/pleasant or not. But I'd bet almost anyone a pack of gum that my ears could not detect being hot or weak at 20 hz vs. 30 hz vs. 40 hz. It would either sound hot or sound weak or sound right on overall. And, I'd bet two packs of gums that even the typical non-aged, well-tuned golden ears would not be able to tell either (in a true blind test, that is...). For me, if it's hot, I could tone down the EQ in the UMC-1 OR I could turn it down via the sub's gain knob...I'm pretty sure either would work.
For any system, my overall gauge has been, "does it sound good" - independent of what some meter might say. I'd bet (based on what I read) that most would listen to the UMC-1 set up to its best and say, "gee, that sounds really good!" Net, I have to wonder if the theoretical nuances raised here really matter in the practical world.
Anyone have a POV (esp. one based on listener review data and not theory) on that?

Dyohn, Read my comments in UMC-1 firmware from China. Thanks

My subwoofer seems to be running hot even when I use the UMC's internal test tones and a SPL meter. You're not the only one and that seems to be a different issue. Sorry for re-hashing in this thread. I missed that big Markus thread when catching up after a vacation. - LoopinFool Any updates to this? Am I correct to assume that the way the UMC handles bass is hardware coded and not software? Where is this "Markus" thread ? I tried to search for it, but haven't found anything yet.

All of the information so far is for those who have a sub-woofer, in my case I am using JBL base-reflex studio monitors for right - left front units, each having 15 inch drivers and would love to see an option to route the LFE - subwoofer eq capabilities to the right - left front channels.

So, as a solution to the aforementioned issues, could I just plug a miniDSP into the "Mix" output and EQ my sub with that, or does the signal run through the UMC's EQ before it goes out of "Mix"?

I'm using a MiniDSP on the sub output which covers LFE + the re-directed bass and it works very well - certainly there is far more control than you get from Emo-Q.

Well, I'm going to implement a miniDSP to EQ the sub, no question there. I'm just trying to figure out the best (to me) way to hook it up. My question is, is there a not-EQed output that I can plug the miniDSP into? The manual really isn't clear about a lot of things. Good thing Emo has forums =)

You plug the miniDSP into the sub output so you get the LFE + re-directed bass only. If you were to use a mix output for example, you would also get all the sound above the crossover and things would become very messy I would think.

Yeah, but I'd rather just bypass the EQ all together. The miniDSP can take care of crossover and EQ duty at the same time easily.

If you want to do that, you can just set the speakers to "full" make sure Emo-Q is off and then you feed the 7.1 outputs (or the outputs you need from the 7.1 outputs) to your MiniDSP or MiniDSPs. If you just want to do Stereo, you would just need one MiniDSP.
If you want to do all channels you will probably need several (4 or more) and things will get more complicated as you will have to work out how to do your own bass re-direction and merge the re-directed bass from the 7 channels to your sub.

I really can't see doing bass redirection with just the miniDSP. The UMC-1s bass redirection is fine if you don't use the UMC-1s built in equalization IMHO. I do use miniDSPs not only for equalization but for the LCR crossovers.

I agree - it would be doable via MiniDSP but complicated and likely not worth the effort.

I have just ordered an 8x8 MiniDSP in order to remove all bass management, XO & EQ from the UMC-1.
I will set all the speakers to full range and run all 7.1 channels through the MiniDSP. The 8x8 has a built in matrix switcher which allows you to sum all the channels to a sub channel and then has an individual 6 band PEQ for all channels.
This way I can use pure direct mode for 2 channel listening with subs while also having correct bass management and EQ for movies.
