MM 1
Measurement Microphone
Order # 449.350
FEATURES
APPLICATIONS
• Linear frequency response in the diffuse field / under 90°
• Omnidirectional polar pattern
• Calibrated open circuit voltage
• Narrow tubular construction
The 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 analysers 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
negligable 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.
