Measurement microphone MM 210

The 1/2 ”measuring microphone MM 210 opens up the possibility of using a high quality, pre-polarized measuring microphone capsule MK 250 on measuring systems with IEPE supply. Array arrangements and envelope surface measurement methods, for example in motor vehicle acoustics, come into consideration as typical applications.

The electrical connection is made via the permanently attached BNC connector with standard BNC cables. The preamplifier is equipped with built-in memory for microphone identification, with which microphone data can be written and read by the manufacturer/user (IEEE P1451.4 TEDS editor).

We recommend the MH 64 microphone holder with a 1/2 ”clamp to hold the microphone. The use of the 1/2 ”measuring microphone capsule accessories such as windshield, nose cone, dry adapter etc. is possible without any problems.

The measurement microphone can be calibrated with the Pistonfon Type 5002 or with other suitable sound pressure calibrators.
