New mic option from the good folks at Minidsp

post #1 of 137
Thread Starter 
Woke up this morning to find the minidsp newsletter in my mailbox. They are soon to release the 2x8 minidsp in a box--the kit is no longer your only option. Same form factor as the unbalanced 2x4 unit, only grey instead of black. $180.

Also, they now are offering an omni-directional condenser mic that comes with it's own unique cal file. 133 db limit and measures down to 5 Hz. Offered for $75. Not sure how good of a deal this is, because I don't currently have a calibrated mic myself but it seems interesting at first glance.



UMIK-1

The UMIK-1 is an omni-directional USB measurement microphone providing Plug & Play acoustic measurement. From speaker & room acoustic measurement to recording, this microphone provides low noise and accurate results you can rely on. Forget about driver installation, OS compatibility and un-calibrated mics. The Umik-1 is a USB Audio class 1 device automatically recognized by all Operating Systems (Windows/Mac/Linux). It is provided with a unique calibration file based on the serial number to insure an accurate measurement. Combined with REW software or other acoustic measurement software, it is the perfect match for a plug&play measurement system.

Cool mic because it's USB otherwise it wouldn't be special. But this way it appears you don't need phantom power.

You will be limited by cord length though. For me this would be a big deal cause I need about 20ft.
post #3 of 137
No problem with the cord. You can get an extension. I would need about the same length.

So would you still need an external sound card with this?
post #4 of 137
It sure does look like a Behringer ECM8000, which also exists as the Dayton Audio EMM6. Not identical, but very close, quite likely using the same element. The quality control on the Behringer has deteriorated as of late, but the Dayton has a calibration file, and it's cheaper than the Behringer too. The UMIK claims 5Hz response, the Dayton only 18Hz, but that distinction is of little significance to most of us. The Dayton is on sale right now for $38.

Bill it looks like the Dayton xlr so it would require phantom power. This one is USB

OK, didn't notice that. So it's probably a USB version of the Behringer/Dayton, and considering it saves you having to have a separate USB/XLR that makes it worth the price for the convenience aspect alone.
post #7 of 137
it must not need a separate sound card either. i have never seen one with USB OUT before so that saves money as well. this looks like a great deal!

yep. just read the description. no sound card needed.

I don't use a separate sound card, even the cheesy on-board in my shop laptop calibrates to dead flat with HolmImpulse.

Isn't this mic the same as the dayton?

Correct me if i'm wrong as I know nothing about mics.

post #13 of 137
It is a mic that basically has a USB ADC built-in.

Parts Express is offering a Dayton version of the same thing: http://www.parts-express.com/pe/showdetl.cfm?partnumber=390-808

It looks quite similar to the mic used in the OmniMic kit. It seems to undercut the OmniMic significantly given how easy REW is to use. OmniMic does provide some extra functionality.

It is due to be released in January. I plan on picking one up so I don't have to use my external USB soundcard and phantom power unit. I also won't need external power since it will just run on my laptop's battery.

Tux, it appears they both use a standard USB plug so you should be able to buy a longer USB cable. There is likely an upper limit on how long, but I've used 20ft USB cables with other devices.

That's the point of having a USB mic, you don't need an external card or pre-amp.

well the correction graph sure looks better than the galaxy cm140.
it's only 1db down at 5hz. relatively flat until 5hz, whereas the cm140 is only flat to 100hz.

That's because the Galaxy is C weighted. Chances are both use the ubiquitous Panasonic capsule or a knock-off of it.

Cool (and typically innovative) idea from miniDSP. The only thing that would make it better for some uses is both on axis and grazing incidence cal files. But that's minor, and since most people don't (and shouldn't) do much in the treble based on listening position measurements a very minor nitpick.

Huh? I promise your iMac has a built-in sound card.

I used to use an Audyssey mike straight into the mike-in on my MacBook in a pinch. That's good enough for most uses.

Interesting. Though it's also worth mentioning that one can get a pretty good USB mike for free (and measurement software with tones for all eight channels, too) with an Anthem AVR, and Paradigm's PBK kit is I think around $100 with the same mike for those who prefer to see before they buy. I should send my Anthem mike to Cross Spectrum, to see how it compares with the Dayton EMM-6 I bought from Herb last year.

i didnt realize i could use an Audyssey mic. How well would that work?
post #20 of 137
So... You can buy USB extensions? I didn't know that. I need one for the keyboard/mouse receiver on my HTPC. Its in a closet 12ft away.

That makes this mic pretty attractive to me. One less component to deal with.

Perfectly adequately for lots of things, such as for instance getting the the best blend between mains and subs. Not as well for designing speakers, or for EQ'ing very deep bass for people who are into that sort of thing.

hmm. i want one that works well using a minidsp for my subs

if its really this flat this is a super bargain considering the dayton emm6 response is nowhere near this good

I've used one for that. It works fine. They do, IIRC, have some rolloff below 30Hz, but take that into account and you're good to go.

i have the anthem arc mic. don't think you could use the mic with rew.

i thought the galaxy is supposed to be a mic preamp and just output all the signal it gets in line level to the soundcard?

I don't know about REW, as I've not used that program. I have used my Anthem mike successfully with the gold standard measurement program for hobbyists, FuzzMeasure. (Other top-tier measurement programs, such as OmniMic, come with a mike designed to work with the software.)

There's no technical reason, I wouldn't think, why the Anthem mike would work with FuzzMeasure but not with lesser programs.

True, the cal file is locked in a proprietary format. But I'm not too concerned about these. These Panasonic capsules and well-made knockoffs (basically that's what all value-priced measurement mikes use) are pretty good. For example, look at the comparison of the cal files for my Dayton EMM-6 (factory and Cross Spectrum Labs) here. If you don't want to click on the link, the gist is that not placing the mike with lab-grade precision will make more of a difference.

But if you're really, really concerned about the lack of calibration, here's a little secret: run Anthem Quick Measure in the ARC software, then without moving speaker or mike, run the same sweep in FuzzMeasure or a lesser measurement program. You can construct a good-enough "cal file" from the difference in the graphs, if you think they're warranted. Hey, you'e given me an idea for another blog post! smile.gif

i'm gonna have to try them back with rew once i get back home. your suggestion on the quick measure to create a calibration file is brilliant! tho i wouldn't exactly call rew as lesser program.

i did clicked on the link and get a 404

Sorry, my fault. I inadvertently lopped an "l" off the URL (.htm rather than .html). It's fixed now in post 26.
