Array Microphones

array-micsMPA416 is a 1/4” prepolarized free-field measurement microphone. It is an ideal choice for array applications where a large number of microphones are required.

MPA466 is the TEDS version of  1/4” prepolarized free-field measurement microphone MPA416. It has the information of microphone model, serial number, sensitivity, reference frequency, calibration date, and other information to facilitate plug and play and reduce the setup time of the testing system.

sps980MPA436 is another 1/4” prepolarized free-field integraged measurement microphone with he length 24mm and a lower sensitivity at 12.5mV/Pa.
