M2010 / M2015 Measurement Microphone
The M2010 and M2015 are compact and accurate measurement microphones for acoustics, R&D and production. They are particularly suited for applications with restricted space available. Main characteristics: • 1/2” omni-directional pressure microphone • Flatness Class 1 (IEC 61672-1)
M2010 / M2015 Measurement Microphone
• Phantom power 10 - 48 VDC • Measurement range M2010: 24 - 145 dBSPL (typical) M2015: 34 - 155 dBSPL (typical)
The microphones M2010 and M2015 are optimised for a flat, free-field response in the audio range 20Hz - 20kHz. The detachable microphone cable at the pre-amplifier simplifies integration into mechanical fixtures, such as robotic arms. The microphone includes a wind screen, a microphone stand and an individual calibration certificate with individual frequency response chart and sensitivity.
