Product Details

Dayton Audio UMM-6 USB Measurement Microphone 

The Dayton Audio UMM-6 is a professional-quality USB measurement and recording microphone that 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 individually calibrated using a laboratory-standard measurement microphone, for consistent, repeatable measurements on the PC that match the level of precision previously offered only by expensive stand-alone microphones and measurement equipment, and 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.

Dayton Audio UMM-6 USB Measurement Microphone— is rated 4.5 out of 5 by 6.
Rated 5 out of 5 by from Perfectly works with MathAudio Room EQ for FoobarThe key benefit of this measurement mic is that it does not require a separate adapter or mixing board, it plugs directly into the computer. Its calibration file is compatible with the free MathAudio Room EQ component for Foobar2000. In fact, I have a room correction system at the price of this microphone!

Rated 4 out of 5 by from Good measurement microphoneThis is a nice instrumentation/measurementmicrophone, packaged with all required hardwareand software, at an affordable price. For thebenefit of those considering purchasing it, Ioffer some information not in the productdescription:1. It is intended for sound level measurements,not for recording. It has a wide dynamic range(I think it's 135 dB) and so is not particularlysensitive for voice or acoustic musicalinstruments. Still, given its flat spectralresponse, it could prove useful for recordingloud performances.2. The file format for use on Windows PCs is*.wma.3. I agree with another reviewer that the 5/16"mounting screw on the tripod is non-standard.I would have preferred a conventional 1/4", too.4. The entire user's manual is one pagelong. Given that it is a plug-and-play USBdevice, that is all that is really needed formost applications, but don't expect much interms of technical documentation.

Rated 5 out of 5 by from Great Mic, Great QualityThe mic arrived packaged well, and the included case is a great way to transport everything. I use this for my car, as I compete in Sound Quality in Car Audio. It is invaluable as a measurement mic, letting me see the problems I am hearing, and fine tune my system.I have used it for my home stereo as well, but not much to tune there, just speaker placement. Thanks to Dayton for another fantastic product!

Rated 4 out of 5 by from Great mic, except.....Here's the deal.....the mic is very well made, comes in a case, incudes a decent length of USB cable, mini tripod, however I can't imagine anybody not wanting to mount it on a tripod. I was disappointed to discover the female thread on the mic holder is not the standard 1/4" thread of a tripod mount, but a larger 5/16".I would absolutely purchase again, but I cannot give it 5 stars because of this overlook.

Rated 5 out of 5 by from Perfect for REWI use this mic for taking measurement sweeps of home theater and hifi systems using REW and it works perfectly. Not having to worry about a pre amp or phantom power is nice, just plug in to USB and go. I have not gotten the mic independently calibrated so I have to trust that the supplied cal file by serial number is accurate... Nothing suggests that it wouldn't be.

Rated 4 out of 5 by from Car Audio TuningGreat product! For some serious car audio quality, I use this mic with my laptop, and some software called "Room Equalizer Wizard" to measure system response and properly EQ the sound processor.If you want to take the next step in car audio tuning, this is a very good choice.

What is the noise floor of this measurement system?

The specs mention 127db SPL as max level, and S/N of 70 db (A weighted). Does that mean that the microphone has a noise floor of 57db SPL (127-70) or is some other reference level used for the S/N measurement?
Asked by: TedM
In signal theory, the noise floor is the measure of the signal created from the sum of all the noise sources and unwanted signals within a measurement system.Microphones themselves noise floor is practically immeasurable, adding in a preamp stage to make it function is were thing begin to change and 99.99% cause of hiss / hence, noise floor.Other noise floor causes:thermal noise, black-body, cosmic noise as well as atmospheric noise.57db refers to the lowest measurable sound pressure on the diaphragm that'saccurate within manufactures specifications.Us sound engineers refer noise floor as "AIR" stemming from electronics circuit hiss.
