Its not good business, and not what I am use to when it comes to Emotiva products. If anyone from Emotiva reads this post, you have alot of customers who are not happy with this situation.

Does Emotiva actually read these forums? I have a hard time believing they wouldn't want to fix this, and would deem the existing ears satisfactory. Would be nice to get some sort of statement from them...

People have made them aware via phone and e-mail, so even without reading this thread they have been informed. It's sad to hear they just say that it's correct and move on without just looking at how the spacing of the mounting holes is off, the diagram I posted of proper rack spacing should be more than sufficient to prove the mounting holes are drilled wrong, hell the fact that they have customers posting pictures of them not fitting should have been enough really. But considering this has been going on for over 6 months I wouldn't hold my breath, I would really much rather have the ears than have to buy the MA shelf, but I don't see them ever correcting this issue with their rack ears.

I sent Emotiva an e-mail this morning explaining everything I have written in this thread with the diagrams, hopefully this will get a response as to whether they plan on revising them or not. If they still somehow maintain they were drilled correctly, or do not have plans to make revisions, I will just have to settle with the MA rack shelf for my UPA-5

Wow, looks like quite the hot topic here. It looks like there is a lot of speculation, confusion and such so I will try to clear things up. Let me start by saying the rack ears were made to spec and are in fact made correctly and here are the reasons why. All of our equipment is made for consumer use and as such use convection cooling rather than forced fan cooling like pro gear so they will be silent in operation. Since the rack ears are the exact same size as the front face of the gear it was designed for, a certain amount of space above and below the gear is required to facilitate proper cooling even in a closed rack system. The rack ears are non-standard in respect to mounting on a specific start point, but they are specifically designed to be 1/2RU off to allow for cooling. I hope this helps to clarify things. Lonnie

The Rack mounting parts are the URE4 for the 4RU tall components like the XPA-2,3,5 and the URS 2 are for the UMC,USP,ERC etc. components.

Thanks for the explanation Lonnie, it was one of my original theories about the space for cooling, it just wasn't really explained that it was done intentionally, so people expecting rack ears to fit their amp in a standard 4RU space were a tad surprised. Normally people would space components out in a rack system to still allow cooling anyway, none of my components are stacked directly, there is always at least 1RU blank panel between components, up to 3RU for ones running hotter than others. If you ever decided to make a batch of standard mounting space 4RU brackets I'd be first on the list!

Understood. Maybe we will make a special trim piece out of 1/4" billet to finish it all off.

Now you're talkin' Make a trim piece that makes it all fit perfectly into a 5 RU space and I'm sold.

Thanks for chiming in on this Lonnie. I was thinking of making some custom blanking panels, but it would be awesome if there was a black anodized one offered to match. Sign me up.

Lonnie Thanks for the explanation, Lonnie. The idea makes sense, but I'm not sure the execution does - the gaps introduced by these rack ears has very negative aesthetic implications. As mentioned by others, it's standard practice to leave gaps between equipment to facilitate cooling. If you were to introduce anodized trim strips to fill the gap, that would be a huge improvement...

I hear ya, but I have to say I have had a lot of emails and phone calls from people wanting to remove the feet on the gear and literally stack the gear on top of each other so it looks like one large piece. You would think that leaving a gap would just be good common sence but that isn't always the case. So when we do things we have to consider worst case scenerio. But like I said, I will look into what would be needed to make some trim pieces.

Thanks for finally clearing this up even though it's taken about six months for an explanation. Now I just have to figure out how to fabricate 1 1/4 rack space vent panel to make my rack look finished like it's supposed to be. Maybe I can cut down a 2 space piece. It's no fun when manufacturers have to engineer things to be idiot proof.

I have to agree, its good that the item has been cleared up. It took entirely too long for it though. Also, do you think you would have already made trim pieces if you know its going to be off 1/2 space on the rack ears? Asthetics mean alot to most people, me being one of them

Lonnie, you have this figured out yet? What do you think the odds of trim pieces is, in reality? I need to figure out a mounting solution ASAP - either buy the rack ears and hope for some trim pieces, or bite the bullet for a Middle Atlantic custom shelf (though, the UPA-5 is not in their database ). Anyone have any cheaper alternatives for mounting in a MA rack?

I hate to say it but you are probably going to have to get the middle atlantic custom shelves. Look how long it took them to "address" the rack ear problem. I mean come on, you mean that 6 months ago you couldn't have said what was posted last week? The rack ear deal is a real black eye for emotiva in my opinion.

Anyone have any cheaper alternatives for mounting in a MA rack? I would imagine you could get the Middle atlantic shelf made for any of the amps like xpa-3 or xpa-5 or upa-7. Arent they all the same size? Im pretty sure they are. I have seen many different combos stacked and they all look the same to me.

They make racks for anything, whether it's in the database or not, no extra charge. You just have to fill out a spec sheet. And in this case the upa-5 & 7 are the same case/platform anyway so the MA rack works with both.

But like I said, I will look into what would be needed to make some trim pieces. I'm sure you're swamped and all, but could I make a suggestion here? There is really no point in advertising a 4RU unit if it can't be used in a 4RU space safely. So, here's my idea: For the 4U amps build a rack faceplate that will bolt-on in place of the existing aluminum trim. The trim will be tall enough to fill standard 5U space. The area between the aluminum trim pieces, where there is only space, will be covered with a perforated blanking piece. Perhaps something like this... (Sorry, crude example done in Visio)
