Here is a link to my first REW measurement. Its not what you asked for because I have spent the entire time so far with the UMC chasing down a ground loop. Having to order a fiber optic HDMI cable to beat it. But that is another story.

Here is the link. Its the center channel along with the sub, and one filter applied in the Xilica. 45 hz -8.25db .21oct q=6.863

Noise floor in room is read to be around 42dB because the UMM6 mic is known to not measure the noise floor any lower.

Thanks. Looks pretty good. Strong reflection after 2ms (floor/ceiling?). Bass array needs better time-alignment.
What does the sub array look like without the filter and center? Set crossover to 250Hz for the measurement.

I wonder if that reflection is the false screen wall or the soffit.

I was thinking that above 200hz the graph looked pretty bad. Is that normal behavior? Your 1/48 smoothed graph above looks extremely different.

The reflection might be the chair. Must be something very close to the speaker and/or the mic.

Response doesn't look bad, it's normal behavior. What you see is room modes and reflections.

Lol I am running tests now.. I forgot the LFE channel runs 10db hot so I got a nice surprise of 99dB at 12.9hz. Found a can light rattle (just loose).

My link above should have the new set of files now.

All of the new tests are with the UMC-200 now.

13Hz seems to be your first room mode. It's visible in your measurement. How large is the whole structure around your HT?

The theater is at the end of the basement. But the rest of the basement is another 1500 sq ft or so. The room is normally sealed but the door had to be cracked for the HDMI cable to reach outside the room to my equipment rack.

So everyone with a XP2040 check your settings if REW delivers low Q settings at subwoofer frequencies. Normally REW uses the unsmoothed response below 200Hz. Above 200Hz it matches the smoothing set under "graph controls".
Everybody watch out for the next REW beta (b22). It fixes the poor results with XP2040 and has a fix for another EQ matching issue.

New user set-up questions

Markus,

I'm a little late to the party, but my I am replacing my Onkyo PRSC885P and just ordered UMC-200.

I watched the setup videos on the Emotiva website and noticed when going through the menu's there was a "Bi-Amp" option which I would like to use.

I don't see any mention of it in the .pdf of the user's manual and was wondering if you were familiar with it. If it is like my Onkyo, I would use the rear surround output jacks in addition to the front output jacks? Where can I find more detail on this?

Also, I use a Monster Power Center for my components. It has a remote “DC In” Control allowing me to automatically turn on the PowerCenter via the Remote “DC Out”. But the connector to the Pre-amp is a normal wall outlet "plug" which would not work with a pre-amp without a place to plug it in (my Onkyo and ohter receivers I have owned had at least one such plug on the back). Where can I learn more about the triggers on the UMC-200 so I know if it is compatible with my Monster Powere Center in some way? I like the flexibility of my amplifiers turning on automatically when I turn on my pre-amp.

Thanks in advance for your help.

Tom

thos19, just set up my system this weekend. Ran a trigger cable from the UMC-202 to a Marantz MM7055 amp' and it works fine. I also use a Monster power center, HTS5100MKll, and tried a couple of hookups with it but prefer the trigger connection.

BTW, after running the EmoQ Gen2 I think it is just about worth the price of the unit. No system mix of components I've had over many years has sounded as good as my current setup.
And this in a room that is far from ideal.

My current setup:

Pioneer 60" 140FD Monitor
Emotiva UMC-202
Marantz MM7055 amp
TiVo Roamio Plus DVR
OPPO BDP-105 Blu-ray player
Darbee video enhancer
Monitor Audio Gold speaker system 5.1
2 Velodyne 12" sub woofers

Thanks elphillips. I'll consider trying it that way.

BTW, I am using a TiVo series 4. Did you need to output the audio via toslink to your UMC-200? I had read about HDMI audio issues in hooking up TiVo's to the UMC-200, and that was mentioned as a work-around.

My setup is older, but works pretty well:

Sony KV46XBR5 LCD TV
NEW: Emotiva UMC-200 processor
Chiro C500 & C300 amps
Tivo Series 4
AppleTV
Playstation 3
Mirage 3si (front), Csi (center), OM-R2 (side surrounds), BPPS-210 (sub)

How would you like to use bi-amping?

thos19, connected TiVo to the UMC-200 with HDMI. Optical will work. You have to go into the menu and pair the optical with the HDMI your using for video.

Just put this together this weekend.

Very bad idea to put speakers in a cabinet as shown in the picture. Horizontal response will vary a lot due to lobing (interference effect between tweeter and woofer). Those speakers are designed for vertical placement.

Yeah, but it looks cool. With respect to Mr. D'Appolito, I'll consider placing them on top of the cabinet, upright.

My front speakers are very large, and with my Onkyo pre-amp (PRSC-885P), Bi-Amping allowed me to have a separate amplifier channel for the tweeter/mid-range and have a separate amplifier channel for the woofer (providing, in my opinion, improved bass and treble performance).

With my Onkyo, the FRONT L/R outputs feed the front speakers’ tweeter terminals. And the SURR BACK L/R outputs feed the front speakers’ woofer terminals.

I saw the term "BI-AMP" on the menu tree in the setup video on the Emotiva website. I was wondering if the UMC-200 had the same Bi-Amp setup.

The short answer to your question is yes, it will do this very simply. In fact, it sounds like the Onkyo uses the exact same process to allow bi-amping of your speakers. You give up surround back speakers and gain bi-amping.

Not sure how these speakers would benefit from bi-amping, especially from the useless "bi-amp" implementation the UMC-200 offers. I'd use the passive crossover they came with. Soundwise it's more important to get the splice to the subs right.

I bought these when I worked for Tweeter, Etc. in Boston back in 1993. The Mirage rep. we worked with recommended using the bi-amp option when I bought them via re-seller accommodation. I never questioned the suggestion and I've always been pleased with the sound.

Got my UMC-200 and set it up over the weekend. Very impressed so far. The sound is excellent, though the automatic calibration via EMO-Q listed the speaker distances significantly higher than the actual distances (12 feet vs. 28 feet, in some cases). A partial result (to me) is an excessively boomy bass response. Maybe the vaulted ceiling of my room is hurting the calibrations? Is it recommended that I re-run EMO-Q, or input the distances manually?

EmoQ is not known for accurate distance measurements. Enter them manually. It's a simple process. I had to do the same, and I have still ended up going with a Flat EQ instead of the EmoQ settings. Truth be told, EmoQ didn't change much, a slight roll-off on the highs. I prefer the Flat sound.

I still want to spend some time with REW and the PEQ in the UMC, at least for my sub, but everything sounds good enough now that I'm not real motivated to spend the time yet.

Don't waste your time with Emo-Q. It's known for not being able to set speaker distances accurately and what it does to the in-room response can only be described as distortion.

Get a SPL meter to set speaker levels and use an ordinary measuring tape to set speaker distances.

If you want to really improve your system with an UMC-200 you'd need to learn how to do acoustic measurements. Here's a good start: http://www.roomeqwizard.com

I'll grab the laptop and the SPL meter. You guys buy some beer on the way over.
