Dayton Audio UMM-6 USB Measurement Microphone 

The Dayton Audio UMM-6 professional-quality USB measurement and recording microphone is designed to work with industry-standard third party recording and measurement software. The rugged construction and compact size make it the perfect companion for audio professionals who must work on-location performing acoustic analysis, monitoring audio levels, or recording. Each UMM-6 is calibrated individually using a laboratory-standard reference microphone, for consistent, repeatable PC measurements that match the level of precision offered previously only by expensive stand-alone microphones and measurement equipment. Works great with the Room EQ Wizard software.

A carrying case with foam insert, 10 ft. USB connection cable, and a mini tripod mic stand are included with the UMM-6. 

Calibration Note: A unique serialized calibration file is available for the UMM-6. This calibration file can be used by most audio-analysis software. To obtain your individual calibration file, visit Dayton Audio's website where you will be prompted to enter the serial number from the body of your UMM-6. After entering the serial number, your download will start.

Rated 5 out of 5 by from UMM-6 Measurement Mic ReviewFirst thing is " lets realize this is a sub $100.00 Mic and you get much more for that in my opinion. Case works fine , Clip is Fine, Calibration file was close for most people it will be more than adequate.If your doing quick work like figuring out RT 60 times with let's say Audacity or some other freeware the mic will pay for itself the very first use.In all good cheap USB mic with better than decent attributes for less than $100.00 why wouldn't you own one?Last note to all " Please don't expect proper measurements with a solid mic stand as your base " You must isolate the unit from a stand " even if you rig up a bungee with rubber bands, NO the carpet is not considered isolation" Rock On!!!

Rated 5 out of 5 by from Seems to work wellUnfortunately I don't have any other measurement equipment to compare its results, but I used it to calibrate the listening experience of my home stereo system, and the results were great.

Dayton Audio UMM-6 USB Measurement Microphone 

About 75% of the time my UMM-6 will come up as not a recognized device in Windows 7 and it will no function. REW will not recognize it, and it will not record audio. Does anyone else have this issue? Is it a bad micx?

Asked by: AverageJoeAudiophile

What is the max SPL this mic can measure? Is it as accurate as the mic that is used with a TermLab set-up? I saw the max SPL of 127 @1%THD at 1000Hz. Does that mean it can only measure up to 127db at 1000Hz? What about a 40Hz tone?

Asked by: Necco
This mic is capsule limited at roughly 120 dB. At such a low frequency it might be slightly lower than that.
