Description

iSEMcon EMX-7150 Matched Pair.

Matched microphones have the same sensitivity value (m/Pa), and are packaged together with other microphones that all have the same sensitivity. This means they will produce the same output voltage for a given input, and therefore present the same signal levels to the analyzer as long as the preamp gains are matched as well.

This is not the same as having matched frequency response – typically, measurement microphones have nominally flat frequency responses out of the box, and if desired, tolerances can be further tightened electronically with a microphone correction curve. Sensitivity-matching microphones involves sorting of hundreds of capsules to find individual capsules that fall within a close tolerance. Once they are found, they are packaged together to be sold as a set.

In practice, this means you could take a matched pair, triple, or quad etc. – calibrate one of the inputs for SPL – and copy the calibration value to the other inputs; they would all match. To match the microphones in frequency response as well, simply load each microphone’s correction file.

Note: Each iSEMcon EMX-7150 comes with individually measured and serialized calibration data. Data can be downloaded from the iSEMcon website by entering your mic’s serial #.

  • Industrial Acoustics
  • Room acoustics analysis
  • Sound reinforcement
  • Real time analyzers

The EMX-7150 is a 1⁄4” microphone made from stainless steel and using state of the art water tight Neutrik*2 connectors has a very accurate frequency response combined with the capability to measure high sound pressure levels up to 145dBspl. It is low impedance measurement microphone that can be operated from 12…52 V Phantom Power which is available on most professional microphone preamplifiers and professional computer interfaces. With its mechanically robust design it is well suited for harsh environment use such as open air sound reinforcement measurements. Its class 1 frequency response (NOTE: NOT A CLASS 1 MICROPHONE) makes it predestined for Room acoustics analysis including recording studios and home theaters. It can normally be used without the included freefield calibration data file for compensation. In this case take the individual calibration data as proof of its superb performance.

Our super protection windshield SWS -7 is recommended for open air use when limited amounts of spraying water as well as trickling water impact the microphone.
