The MKH40 has a large number of applications, for example as a main microphone, especially in lightly reverberent or acoustically less perfect rooms, with instrumental groups or for speech applications. Its wide-angled, neutral directional characteristics and high level of reverse attenuation ensure an exceptionally balanced sound.FeaturesMaximum front-to-back ratioExceptionally low inherent self-noiseSymmetrical transducer technology ensures extremely low distortionTransformerless and fully floating balanced outputSwitchable roll-off filter to compensate for proximity effects at a distance of approx. 0.5 mSwitchable pre-attenuationBlack, anodized light metal bodySpecificationsPick-up Pattern: CardioidFrequency Response: 40Hz - 20kHzSensitivity (free field, no load, 1kHz): 25 (8) mV/Pa +/-1dBNominal Impedance: 150 ohmsMin.
