Dayton Audio EMM-6 Electret Measurement Microphone
Dayton Audio EMM-6 Electret Measurement Microphone is rated 4.7143 out of 5 by 21.
Rated 5 out of 5 by from Great measurement mics for the priceI do system optimizations for local churches. These mics work great for use with Smaart (or whatever software platform you prefer). Because of the included calibration files, when I pulled all four of my new mics up, they had an almost identical spectrum plot. For this price? That's awesome!

Rated 5 out of 5 by from Essential piece of gearBesides it's affordable price, the major factor in choosing this specific microphone was ability to obtain (download) it's own calibration response data from manufacturer's website. 'Own' meaning the actual microphone, as each one is measured separately and flagged with serial number. Overall, it's a solid product and I'd gladly recommend it to anybody looking for measurement mic.

Rated 5 out of 5 by from Quality Measurement Mic at Great Price PointI needed a small condenser mic to measure the response in my room before and after applying acoustic treatment. This Dayton Audio mic - in conjunction with the freely available Room EQ Wizard (REW) program - has done everything I've needed it to at a ridiculously low price. You can even download it's unique frequency response calibration file from the Internet for free. Nice!

Rated 5 out of 5 by from The little mic that could.For about the cost of getting your mic calibrated, you can buy this little mic which not only comes with it's frequency response curve in the box - but also has a downloadable txt file that can be used as a software microphone cal file.I purchased two of these mics - they have sequential serial numbers, and slightly different response curves - however, the calibration file straightens both lines out.They perform well for room and speaker calibration - I ran mine against a slightly more expensive mic which has had third party calibration, and I found that the responses were comparable - if not a couple dB less gain overall.Other than that - response data seemed consistent with other data I had generated - which is really what's important.

Rated 4 out of 5 by from Cute story.Did a sound job for an acoustic band playing a Barn Party. Now I'd had the Dayton EMM-6 for a month or so, bought it for this kind of job. I'd had used it in studio for testing, and tuning speaker systems. And it worked well. Produced very earpleasing results. Very close to the results I got using an Earthworks. Used it in the theatre and really liked the results there, too. Self noise was low enough that it wasn't a factor. Frequency response was broad and flat, distortion was low enough that harmonics didn't interfere with results. And I mean really flat. I didn't expect the results I got when I did my tests. It's not a B&K, or Earthworks. But, then, for a Barn Party, would you really want to take an Earthworks?So, I'd done some preliminary tuning of the amp/speaker complex using Harman's System Architect on my XTI, and got a nice smooth, flat sound with the Crown amp and Klipsch speakers, in the house. I'm figuring small variations, and tweaks only when I finally get to the Barn.I took everything out to the Barn Party, and when I got set up, I put the EMM-6 on a stand, ran it to my Analyzer, fired everything up, and found some real hard resonances to be tuned out. Just about the time I opened System Architect, someone knocked the stand over. And stepped on the EMM-6, and tripped over now free mic cable, and dropped a tray of buffet line service on the mic. Before I could get over to the mic/stand and cable and pick things up, the guy driving the scissor lift ran flat smooth over the stand, the mic and cable connector. :) I dug the mic out of the straw and dirt, and took it back to the sound board to check it out, and tripped on a concrete ramp in front of the sound board, dropped the mic on the concrete, and the farm dog, supervising the set up, grabbed it and off he went.By the time I caught up to him, he'd chewed the head off the mic, and was burying the body in the yard.So, though I did get to use the mic, and found it to be much more than I expected, the very job I bought it for....well, it just missed living for its destiny.The job came off ok with what I'd already done, and I made a point of ordering a new EMM-6, and a new mic stand that night when I got back.Bottom line, I recommend this mic. It's quiet, sensitive, though not level calibrated, and very flat, with an acceptable distortion. As a sound system set up tool, very nice. As a dog toy...a little expensive.

Rated 5 out of 5 by from Great overall productIts great to finally do some room acoustic analysis, this mic made that possible. Construction is good, response is good, and having a cal file is great. Now to fix my listening room...

Rated 5 out of 5 by from Seems 2 b fine.Hav'nt had it long....so far so good! Looks identical 2 the Behringer..... :( But 2 has better sensitivity, and reads tit for tat with another more expensice mic I have so ....... But really, 4 the bucks how can U beat it??? And with a windscreen??? I would buy another and hope it's just like this one. For basic room analizing I say go 4 it!

Rated 5 out of 5 by from Little omniOutstanding value for a decently performing small capsule omni. With the correction file downloaded and applied to your testing software you have a pretty good testing setup. I use the 1/3rd octave TrueRTA package, also a fine value.For the budding recording hobbiest/engineer, buy 6 or 12 of these and learn how to PLACE mics from the getgo. Save the spendy mics for later after you learn your craft. You would be astonished at how well this little omni can do when placed well. Embrace the Inverse Square Law, grasshopper.

Rated 5 out of 5 by from Don't buy anything elseAt twice the price a mic this built this well with it's own individual cal file would be a real bargain. At less than $50 the EMM-6 has absolutely NO competition. Rock solid construction, ships with a nicely padded plastic carrying case... and did I mention a unique cal file for each mic???? This does exactly what it is supposed to... if you are reading this and you understand what it does then you are wasting money buying any other similar product. Superb. Running REW and TrueRTA with it.

Rated 5 out of 5 by from Simply Awesome for the Money.This is a high quality, custom calibrated microphone for less than $50. It does what it's designed to do and it does it well. You will be happy with this purchase.

Rated 4 out of 5 by from Nice microphone for speaker measurementsThis is a nice microphone. I use it together with the Behringer 802 mixer/preamp. The combination works well.Don't forget to use a reasonably long (about 1m) straight boom when doing speaker measurements. I constructed a simple one from a pvc pipe (about same diameter as the microphone) and placed an XLR in the end for easy attachment of the microphone.It would have been perfect if the calibration file contained phase information as well, but it doesn't really matter as long as all drivers are measured with the same setup.
Date published: 2012-01-07
Rated 5 out of 5 by from I couldn't ask for more at this price rangeI've never used another measurement mic, so I can't compare it to anything, but I can say it does the job. I've been using it with both HOLM Impulse and Audata's SpeakerWorkshop. Both programs accept the calibration file. The data I get makes sense, and the speakers turn out well, so I guess it must be accurate. The included mount attaches conveniently to my camera tripod. The protective carrying case is a nice touch. It's big enough to re-cut the foam and add my power supply and a cable adapter. I can't think of anything else a hobbyist could ask for.

Rated 5 out of 5 by from great micI bought this mic a while back and it hasnt let me down since. I used rew for the software and a micmate for the power. The emm6 is the cheapest mic I could find and with the cal file makes it a crazy good deal. I mainly used the mic to take measurements in my car and find out that the car is a terrible place to put speakers. I also found myself cutting my speaker mounts up and completely redoing my car.So overall the mic is a great value and really good quality but it did end up costing me time and fiberglass, other than that for car and room measurements you cant beat it for the price.

Rated 5 out of 5 by from Cal file incorrect?Great deal on a nice mic but beware the supplied cal may not be very accurate.

Rated 4 out of 5 by from Very impressive measurement mic for the $I got this for a business trip to Asia. I didn't want to take my Earthworks M30. For frequency response measurements, this is very impressive. With the calibration file, it is amazingly close to my Earthworks M30. It is not quite as sensitive as the Earthworks (about 5dB less). I have not compared the self noise or recorded with it, but will after I return from my Asia trip. I will also compare how it does with THD measurements.

Dayton Audio EMM-6 Electret Measurement Microphone

EMM-6 vs Omnimic USB Frequency Response Below 18Hz

I'm wondering if these mics use the same internals. Your site says the Omnimic setup goes down to 5Hz, and the EMM-6 says 18Hz-20KHz. Will the EMM-6 show me bass below 18Hz? I need the best one for ultra low bass response. Which one should I get?
Asked by: MasterODisaster
If certainty in very low bass is what you need, the OmniMic is your choice. Irrespective of whether the "internals" are the same, the OmniMic is a system of hardware and software that has been calibrated to meet or exceed published specs. At the production level, the frequency response of these kind of mics varies. Most of them meet minimum design specs and are sold at that level. Those that have superior performance specs are selected for use as reference mics. From there, other factors, such as case design and tuning, come into play. The EMM-6 is a great bargain but you should not buy it with the expectation that you will have flat coverage below 18hz. An aside: the world of 5hz is an unpredictable place. Unlike 5khz, where smoothing the edge of a surface can have an effect that you can hear, large changes in architecture can be required to effect small changes in response at frequencies below 30hz.

Is this mic suitable for use with a home theater receiver that has audyssey or other automated channel setup features? Thanks.

I have a Denon 2808ci and need a mic to run auto-setup. If this isn't the right product, do you have any other suggestions?
Asked by: jmarchitect
You would have to ask the maker of the receiver. They often purchase microphones that aren't truly flat and compensate with EQ circuitry in the receiver. So while this is an excellent mic- it's output curve may not match that of the electronics within your receiver.

Do a sound level calibrator fit in it?

I know that a calibration file come with every mic but if I want to ajust the calibration before each test is the tip of the micro fit in the hole of the calibrator? Or what is the outside diameter of the tip of the micro?
Asked by: jo prev
I am not aware of any microphone calibration system that involves sticking the capsule end of the microphone into a hole in a calibration device.If you want to use the calbration file to "perfectly" flatten the microphone response, you would apply counter EQ with an analog or digital equalizer.

Is the supplied calibration file ON or OFF-AXIS?

Basically, measurement mics can be used either facing the audio source or facing straight up (usually for surround sound systems). The calibration file should correlate with how your measuring. Pointed at an audio source would require an ON-AXIS calibration file. Pointing the mic straight up would req an OFF-AXIS cal file.
Asked by: JLiRD808
The EMM-6 is designed as an on-axis measurement device.

phantom power for UCA202

I'm looking for the lowest cost way to connect the EMM6 for use with ARTA. I already have UCA202 which has line inputs. Is a phantom power supply sufficient or do I also need to add a preamp? It seems like I can get all the gain I need from the sound card.
Asked by: JackNC
Yes, it is a condenser mic.

How reliable is the calibration file for this product?

I know that Dayton supposedly offers a "unique" calibration file for each mic when u enter it's serial number, but can it really be counted on as totally accurate? Competitors offer calibrated measurement mics for AT LEAST twice as much $$$ ....wondering if this is the real deal or some fluff.
Asked by: JLiRD808
The calibration files for these microphones are very accurate. Each mic has a linear calibration file consisting of 256 entries (25 per octave) at a resolution of 0.1dB. Each file is tailored to ONE specific microphone, not to a particular day's production run or group of microphones which measure within a certain tolerance.

With this microphone, will the xenyx mixer and a cable be all that is needed to measure room frequency response?

Asked by: ariel
As long as you have some kind of audio diagnostic software on your computer, yes. The Xenyx mixer would provide the phantom power for the EMM-6, as well as the USB interface to your computer. If you do not possess any such software already, I've included a couple links below to relevant products that we carry.

Phantom Supply voltage

Can this EMM-6 operate under 8V supply? My Clio box has 7.8V supply. I tried it but somehow the sensitivity doesn't seem to be there. Just out of curiosity, I connected a small headphone and it seems to work much better as a microphone.
Asked by: Young
This unit requires phantom power in the range of +15 to +48 volts.

How to connect phantom power

The data sheet gives pin numbers 2 & 3 for the microphone but no pin numbers for phantom power. I assume that phantom V+ goes to pin 1 but what pin is common for the mic element and phantom power? Is the common pin 2 or pin 3?

I would recommend using an in-line phantom power supply, I've linked one below for your convenience.

to connect the notebook

I wonder whether to connect directly into my notebook I need some other product, because I have installed an RTA and I need a microphone to make MEASUREMENT I need anything else to plug in the USB port?
