Description from the seller
Condenser microphone for audio measurements
The Beyerdynamic MM 1 is a measurement microphone designed specifically for measuring 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 testing and other applications. The microphone’s slim tubular construction ensures it has a negligible influence on the sound field, so that increases in pressure level are avoided thanks to its linear frequency response.
Main features
Transducer type: Condenser (back-electret)
Operating principle: Pressure
Polar diagram: 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 Ohms
Load impedance: ≥ 2.2 kΩ
Connector: 3-pin XLR
Length: 133mm
Diameter: 9-19 mm
Weight without cable: 88 g
Frequency response: 20 Hz - 20 kHz (50 Hz - 16 kHz ± 1.5 dB)
SPL max at 1 kHz: 128 dB
S/N relative to 1 Pa: > 57 dB
Equivalent SPL: about 28 dB (A-weighted)
Power supply: Phantom 12-48V
