When the folks at Emotiva test the UMC-1, what's the room like where they do so?

They test them?
post #8613 of 17192
It's obviously the most perfect room in the world. Their umc works flawlessly. They got mine back on Monday for repair, waiting to hear something.

Kind of bizarre advice, or, inability on Emo's part to understand or investigate their own software system.

I saw that post at Emotiva Lounge from someone who had verified that his wiring was correct and was still getting a report that the speakers were out of phase. The answer did seem odd. The owner had double-checked his wires and they were correct, plus the behavior of the system suggests that the phase is correct. If the wires between amp and speaker are right, there would seem to be only two reasonable possibilities to explain the Emo-Q results: a hardware problem (speaker, amp, or processor getting the phase wrong) or a software problem (Emo-Q making a mistake when checking phase). I really doubt that the hardware (which is all built by Emotiva) is at fault - software is much more likely. Lonnie's answer is to simply say to set it up however you like. I will give Lonnie the benefit of the doubt and assume that his response is not meant to suggest that the customer likes the out-of-phase sound and can't tell red from black (although one could interpret it that way), but in doing so I'm not sure what value his answer has. It doesn't address the question of why the owner's Emo-Q setup mis-reported speaker phase.

Did the LMC-1 really get all worked out? As I recall, there were a number of issues that were either not resolved or were resolved by saying "we can't fix that, we designed it with that limitation" when they discontinued the product.

If you switched the wiring on the speaker so it registered as in phase, then it would actually be out of phase and play wrong with real material...

The LMC-1 never did become a sold choice. It definitely had its limitations.

This is not uncommon with many brands, I have had Onkyo and Denon choices tell me my speakers where wired out of phase (The speakers were just fine). A person just needs to confirm with a simple test and then ignore the message.

Field Testing - Cross your fingers and issue whatever you have, hoping it works.

Looks like Emo opted for field testing.

been in the software business for over 20 years.

There is a reason companies offer Beta releases all the time

If anyone runs a business where they build a product that requires testing they would understand that there is no profit in testing something 100% because its just too costly to test. Especially in a business where you contract out the manufacturing of the product!

Has anyone tried the USP-1 as a Headphone amp?

I am interested in setting up a small desktop solution that could possibly turned into an office two channel unit. But for now it will mainly be used to drive some hard to drive headphones and use a cheap discman as the source.

Thoughts?

They have a dedicated theater room for real world situation, and I suppose they must test them in the lab, too.

If you check the Emotiva website, and look for a link to EMOTV, there is a video that is filmed in the HT room.
post #8620 of 17192
I know about the theater but if they don't have a regular old room with not much special going on, then it's no wonder they're releasing buggy processors.

I have had the UMC-1 since monday. The UMC-1 has the potential of entering into awesomeness. It does sound amazing. But even after the FW upgrade is still has bugs. IMO..EMO-Q is flaky at best. IF your the type who completely rely's on auto room correction SW you may be disappointed with this unit. Emotiva has stated they will continue to address lingering issues. There are still other minor bugs I've had..none of which has stopped me from enjoying a movie or listening to some tunes. However there is one reported issue that I will have to investigate. Someone stated that the UMC-1 subwoofer equalizer has no effect. He was using REW..it could be a setup issue. I'm gonna run some subwoofer test tones tonight off of a test CD and using my radio shack meter to see if I can confirm his findings...

The UMC offers a lot of user controls and flexibility..especially in regard to bass management. A tweaker could really love this unit. I'm in the process of setting up REW myself to see what kind of results I can get with the UMC and its numerous user definable settings...

And don't forget about the stereo playback over digital connection issue that seems to be a problem for some people (myself included). WHat I hear is a rhythmic clicking or smearing (about once per second) from the right channel only. Seems to happen only with 44.1 kHz material (or a multiple), and only if the UMC-1 is set to stereo mode. It seems like some kind of clocking error. One other user found it in direct mode as well in certain configurations. The unit(s) at Emotiva do not exhibit this behavior, so I don't know if they are actively pursuing it, or not.

I'll test it tonight, I'm sure you'll get your answer before then. I just bought one of these and it sounds pretty good in 2ch.

I have no problems (so far) listening to CD's via the coax connection in Stereo or Direct mode...

Agree. It does help to label a release as Beta, however.

Emo should maximum profit from the UMC-1 based on your threory.

Do you mind me asking what 'phones you'll be testing this with. I'm new to the "can's scene" but supposedly some are much harder to drive than others. And it seems I picked up one of those - AKG K601's. These are supposedly mother's to drive.

I'm having a shootout Emotiva RPA-1 vs. Anthem MCA-20

Don't forget to let us know how the base management test goes. I believe I read the same comment from someone stating that base management (Sub 11-band EQ) wasn't working even after update. I need base management in my system and this is one of the best selling points for the UMC-1 in my situation. If the sub EQ doesn't work very well or at all, that would be huge for me.

Grado Sr80..I never use the head phone section of any piece I've own...But I think I'll start on that path soon enough, thus upgrading to a better set.

I've own that same Anthem amp, and wasn't too happy with it.Would be waiting to hear the out come.

I'm starting to get into it myself - for a fraction of the price of full-size audio gear you can get sound that is simply awesome. Plus it lets me continue to listen after the kids are in bed

No one says a company should get it 100% right before release. BUT, and IMO this is a BIG BUT, I do think a company should let people know that they are releasing a product that has not been finalized. I personally would not want to spend the amount of time many UMC-1 folks have downloading new "fixes".

That's why beta testing is better, so that a company can get it right or nearly right before release. It seems that there are still many issues yet for the UMC-1. So in my opinion it was released way to early.

Hi all. I just got an XPA-2 and XPA-5. After installing the 2 to drive my left and right mains I get a slight popping nosie out of my left main speaker (Def Tech ST) when I switch channels and I aquire a new audio signal. It always happens on DD 5.1 channels and when I go from 5.1 to 2.0 or vice-versa, but not when I'm on a 2.0 station and switch to another 2.0 station. I am using a Pioneer SC-27 as a pre-pro. I have a Tivo HD connected to a DVDO Edge connected to my Pioneer via HDMI for audio. The amps are connected directly to the wall where I have a PS Audio sololoist installed in-wall. I changed outlets, switched cables (I am using Monster RCA interconnects) and even switched speaker cables. Nothing helped. I did not have this noise when I had an XPA-3 driving my Right, Left and Center channels and also did not get it using a Marantz MM8003. Has anyone else experienced anything like this?
post #8636 of 17192
Does anyone here know the XPA-1's power consumption specs (max, idle, etc.)? The manual's no help. Thanks.

Try swapping the left and right inputs on the XPA-2. If the sound moves to the right speaker, it is in the signal coming from the pre-pro and the amp is working properly. If it stays in the left, it is coming from the amp - contact Emotiva for warranty service.

The popping sound moves to whatever speaker the left channel of the XPA-2 drives. Wouldn't that mean there's something wrong with the left channel?

OK, I just got my UMC-1 will be available April 4th email. Should I pull the trigger or is it still to buggy yet? I don't need it now, as I have a Denon 4308ci with no issues. I was just going to move AVRs around when I get the UMC-1.

So, what is the verdict? Wait a till fall when hopefully all of the bugs are worked out or get it in April?

Mike
