AI-assisted summary
Description from the seller
CONDENSER MICROPHONE FOR AUDIO MEASUREMENTS
The Beyerdynamic MM 1 is a measuring microphone specifically designed for the measurement of sound amplification and PA systems. It is designed to operate with spectrum analyzers to measure the frequency response and sound pressure levels of loudspeaker systems. The MM1 is the ideal microphone for measuring audio signals in research and development, for reverberation tests and other applications. The microphone’s narrow tubular construction ensures that it has negligible influence on the sound field, so increases in pressure level are avoided thanks to the linear frequency response.
Main features
Transducer type: Condenser (back-electret)
Operating principle: Pressure
Polar pattern: Omnidirectional, calibrated diffuse field
Open-circuit voltage at 1 kHz (0 dB = 1 V/Pa): 15 mV/Pa (-36.5 dBV) ± 1 dB
Nominal impedance: 330 Ω
Load impedance: ≥ 2.2 kΩ
Connector: 3-pin XLR
Length: 133 mm
Diameter: 9–19 mm
Weight without cable: 88 g
Frequency response: 20 Hz - 20 kHz (50 Hz - 16 kHz ± 1.5 dB)
Max SPL at 1 kHz: 128 dB
SNR relative to 1 Pa: > 57 dB
Equivalent SPL: about 28 dB (A-weighted)
Power supply: Phantom 12-48 V
