About this listing
The Beyerdynamic MM 1 is a measurement microphone which has been designed specifically for measuring sound reinforcement and PA-systems. It is designed to work with spectrum analyzers for measuring frequency response and sound pressure levels of loud speaker systems. The MM 1 is the ideal microphone for the measurement of audio signals in the research, development, for reverberation testings and other applications.The narrow tubular construction ensures that the microphone has negligible influence on the sound field so that an increase in sound pressure is avoided with high frequencies. A natural reproduction is achieved due to the linear frequency response.Beyerdynamic Mm 1 Features:Linear Frequency ResponseOmnidirectional Polar PatternCalibrated Open Circuit VoltageNarrow Tubular ConstructionBeyerdynamic Mm 1 Specifications:Transducer type: Condenser (back electret)Operating principle: PressurePolar pattern: Omnidirectional, diffuse field calibratedOpen circuit voltage at 1 kHz (0dB = 1V/Pa): 15 mV/Pa( = -36.5 dBV) ± 1 dBNominal impedance: 330 ohmLoad impedance: = 2.2 kohmConnector: 3-pin XLRLength: 133 mmShaft diameter: 19 mmHead diameter: 9 mmWeight without cable: 88 gFrequency response: 20 - 20,000 Hz (50 - 16,000 Hz ±1.5 dB)Max.
