A market success - The new MMS 214 1/2" and MMS 212 1/2" measurement microphones

The market development regarding the newly developed measurement microphones has been extremely positive since the successful launch in 2022.

The growing demand confirms the ambition of the MTG R&D department to develop measurement microphones for extreme operating conditions and particularly demanding measurement tasks.

MMS 214 1/2“ Measurement Microphone with particularly low inherent noise level

• free-field
• 2 Hz to 20 kHz
• 6,5 dBA to 104 dB
• IEPE (BNC)
• Microphone power supply: IEPE
• TEDS acc. IEEE 1451

The MMS 214 has a particularly low inherent noiselevel and is designed for acoustic measurementsof low sound pressure levels close to the thresholdof human hearing.

The electrical connection is viaa BNC cable to devices with IEPE supply.

The microphone preamplifier internally generatesthe polarization voltage for the externally polarizedmicrophone capsule.

The measurement microphone is equipped with a build-in memory for microphone identification (TEDS acc. IEEE 1451).


MMS 212 1/2“ Measurement Microphone for rugged environment

• free-field
• 3,5 Hz to 20 kHz
• 15 dBA to 139 dB
• IEPE (BNC)
• Microphone power supply: IEPE
• TEDS acc. IEEE 1451

The MMS 212 is very insensitive to extreme temperature, humidity, dust and vibration and therefore designed for applications in rugged environments. It can be calibrated with a standard 1/2“ sound calibrator.

The electrical connection is via a BNC cable to devices with IEPE supply. An integrated power-on indicator permanently shows the correct function.

The measurement microphone is suitable for sound level meters of IEC class 1 acc. IEC 61672.
