Dayton Audio EMM-6 Electret Measurement Microphone is rated 4.8333 out of 5 by 18.
Rated 5 out of 5 by from Nice qualityBought this to use with TrueRTA. You can download the calibration file and load it right into TrueRTA. Mic comes in a padded box with clip and foam cover. Seems a quality piece and has worked accurately in tests I've seen of the Mic.

Rated 5 out of 5 by from Great service and product of the highest level.I definitely want to congratulate you for the excellent service offered. The microphones (I have purchased two pieces) are excellent, they have a considerable base of linearity, a sign of good design and control of production, they also have the very substantial surplus value of the calibration, carried out for each piece marked with the serial number. It works, are perfectly linear, on axis.A special note for Parts Express: I ordered two microphones, and they sent me two objects with sequential serial number, one thing that I really appreciated, a sign of professionalism and expertise, as well as kindness. Thank you.Regards, Robert .VREL, Italy

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!

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

Asked by: ariel
This mic "listens" or picks up the room acoustic information only. The 1204 USB mixer is an interface to get this information to a computer to be analized by software. You can also buy a DBX "Drive Rack PA" unit that will do a great job and eliminate this mixer and the computer. There are four models. Choose the one that suits your particular situation.

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
According the specs, as it says the capsule is 6mm. That is the outer diameter of the microphone within it's tolerances. If the calibrator is meant for the microphone or is within same standard it will fit. They work together to calibrate the measuring system for what it is for to be used. You wouldn't be able to do anything for the microphone, its is the rest of the system that is calibrated for the flat curve and your files help for that adjustment. The system runs each range thru the microphone to get the level flat and when you check your speakers it corresponds to that signal.

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?
Asked by: vaguedes
This particular microphone requires phantom power. In order to use it with your notebook, you need a preamp (with phantom power) that has a USB output. I have listed the device you need below.

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.

Do I really need to buy a $100 preamp for a $50 mic

I dont use mic's but I needed to test my speaker designs. Unfortunatly I seem to be caught in a "tar baby" situation. I got the EMM-6. Built the balanced cables. Needed phantom power so I bought the Behringer PS400 $22. True Audio's RTA could not see the EMM-6 on my laptop So researching TA-RTA's HELP told me that the Behringer UCA202 USB adaptor is the way to go. I buy a UCA202 $34. My laptop can now see the EMM-6 but it is way down in the noise <-60 dB at best>. Sheesh. Another answer here suggests a ART USB dual preamp $100. Do I really need all of this equipment to get a micophone <> to work? My laptop sound system has 12 dB boost. Should I use this? Does it degrade the signal with post processing? Seems like using a precision mic and running it through the volume control on a cheep phone.I have tested all the cables and am running phantom power at 48v.
Asked by: Eric
You need to have a good power supply for your mic. Otherwise your readings and measurements will be inaccurate.

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?
Asked by: frank18944a1
I would recommend using an in-line phantom power supply, I've linked one below for your convenience.
