UMM-6 USB Measurement Microphone

I’m using this mic in conjunction with room eq rew wizard to calibrate my dsp-408, which controls my soundstage and it works great! You can also avoid buying a separate SPL meter by using this mic with the SPL meter in room eq wizard

Works as advertised, I'm very happy. The accessories are useful, that calibration file was available and can I use it, and the storage case is very good too. Delivery was perfect. The recommended software Room EQ Wizard ([...] - I use the Linux version) is very well documented and works best. Thank you

EDIT: just wanted to clarify, i recently figured out what the problems were. I didnt have the measurement software set up correctly. There are a lot of things that are default that shouldnt have been the default in my measurement. Since then i've managed to get good recordings. Noise floor is a bit high, low frequency measurements might not give you a quite accurate picture (and they shouldnt) but it gets the job done. --------------------------------- I am NOT the foremost authority on these types of devices, so take what I write here with caution. Its entirely possible i have far too high of expectations or simply dont understand what I'm doing. I'll just explain my proceedures and you can see what you think. SKYPE/VOIP USAGE: This mic cannot reliably be used for this type of thing. It is a high quality measurement mic, but there is far too much noise. I think this is because it is picking up everything around me, including the noise floor of things like my computer fans, the air conditioning, etc. Stuff that your ears normally filter out as background/white noise are easily picked up by this. Measurement/Calibration usage: I was informed by Dayton that you cannot use this to measure anything below 200hz. I still dont know why this is. I think it has to do with "minimum phase issues". I dont know if they meant "it doesnt measure correctly/accurately/precisely below 200hz" or "it will measure but the measurement will be useless". I am quite sure they meant the latter, as that makes far more sense. In RoomEQWizard, i was picking up TONS of noise in the noise floor, but I think it made no difference once I actually played a tone. Overall, this was a pretty terrible purchase. Not because it doesnt work or anything, but because I dont have any clue what i'm doing and what I expected, and the Room EQ Wizard site would have you believe that you can easily measure everything but once you try, you'll quickly find that every source will tell you a bunch of conflicting information that is incredibly hard to sift through. Overall the mic does what it was designed to do: measure stuff. It does the job well, almost too well. It does not require phantom power, comes with a calibration file, and personally i feel it has some issues with its sensitivity and ease of use. Based on that I'm giving it a 3.0 as an "its OK" rating. I dont get any warm fuzzy feelings from this purchase, and i'm sure that if I knew what I was doing I'd feel a lot better about this mic.

Works perfect

Using to test sound system, extremely easy to set up (download config file from Dayton website first) and use

Why on Earth did I not buy one of these a long time ago? No phantom power special boxes, plug into the computer, launch the audio measure software and you ar golden. I honestly have no way to determine the accuracy of the product. My guess is it's pretty darn good and likely way better than most people require. I general these get used for an RTA to see if you are going deaf or just can't hear, or maybe you drank too much. Either way this simplified in one shot what used to be a real hassle.

Very handy tool for finding out how your speakers are ACTUALLY performing. Basically plug 'n' play if you have the appropriate software (REW, HolmImpulse or other similar products). Just remember to download and load the calibration curve (unique to every mike) from the website - there are instructions included with the UMM-6 about how to do this.

Setup is easy, USB to PC. Loading profile to correct response for this specific mic serial number also easy. Worked well to setup pa system eg using Smaart Live. Not sure how accurate it is...acceptable results for price.

REWに使用するために購入しました。UMM-6をMACに接続して、MACの入力装置としてUMM-6を設定後、REWをたち上げると、REWにマイクが認識され、キャリブレーションデータの読み込みもできました。その後、測定も問題なくできています。USB出力のマイクを選定したおかげでオーディオインターフェースが不要となり費用を節約できました。

I found it to give constant results when used with REW setting up a miniDSP 2x4 HD

Use it with REW software... very easy to set and use this mic

カーオディオのＲＴＡ用に購入。 アプリごとに少し波形が異なるので 相性がありそう。 エタニのＲＴＡが一番しっかりきたが アプリの使用がそろそろできなくなりそうなので今後どうするか…

収納ケースは少々安っぽいですが本体はしっかりした作りです。自作スピーカーの周波数特性の計測で使用する目的で購入いたしました。ホームページよりマイクのキャリブレーションのためのソフトと周波数計測のフリーソフトをノートPCダウンロードとて使用しております。価格以上の性能であると思います。
