The MKH 40 has a large number of applications, for example as a main microphone, especially in lightly reverberant or acoustically less perfect room, with instrumental group or for speech applications. Its wide-angled, neutral directional characteristics and high level of reverse attenuation ensure an exceptionally balanced sound. Features: Maximum front-to-back ratio Exceptionally low inherent self-noise Symmetrical transducer technology ensures extremely low distortion Transformer less and fully floating balanced output Switchable roll-off filter to compensate for proximity effects at a distance of approx. 0.5 m Switchable pre-attention Black, anodized light metal casing Supply schedule: 1 MKH 40, 1 MZS 40 shock mount, 1 MZW 41 windshield Technical: Pick-up pattern: cardioid Frequency response: 40- 20,000 Hz Sensitivity (free field, no load) (1kHz): 25 (8) mV/Pa +/- 1dB Nominal impedance: 150 ohms Min. terminating impedance: 1000 ohms Equivalent noise level A-weighted (DIN IEC 651) CCIR weighted (CCIR 468-3): 12 (18) dB 21(27) dB Max. sound pressure level: 134 (142) dB at 1 kHz Power supply: phantom 48 +/-4 V Supply current: 2 mA Dimensions in mm: O25 x 153 Weight: approx. 100g
