Measurement microphone M 102

recordingcapacitoromnidirectional

The M 102 combines high quality measurement capsule technology with a nickel metal membrane and a modular pre-amplifier. The certified capsule combined with a 48V phantom powered pre-amplifier reaches a constant magnitude and phase response and long-term stable transmission properties. A sound calibrator can be used for optimal level adjustment. This mic is ideally suited for applications where a low noise level is demanded as a main mic for recordings that should include a certain amount of room response. It is also perfect as a spot mic for recording instruments close up, where the low frequencies need to be captured cleanly and with detail or for use as main mics like an AB stereo pair or a Decca Tree because of its precise, long-term stable transmission properties. It can be supplied as a matched stereo pair or Decca Tree triple on request. The mic has an excellent transient response and is perfect to record instruments with extreme transients. The sound transducer is an externally polarised capsule with a diameter of 23.8 mm and an extremely thin nickel metal diaphragm. This diaphragm is "grown in place" on the metal structure of the capsule making it one uniform piece. The diaphragm structure is the same in all directions and is a pure sampler of the sound pressure wave without distortions that can happen with other construction methods. The omni-directional pressure transducer is without any proximity effect. Because of the free-field equalisation, the mic has a constant frequency response from below 20Hz up to 20kHz. The static pressure equalisation between the capsule interior and the atmosphere is obtained via a tiny vent into the preamplifier.
