The MKH is a lightweight long shotgun microphone. Its excellent directivity is particularly suited to applications undertaken in difficult conditions, such as high background noise and distance microphone positioning. Its frequency-independant directivity prevents sound coloration from off-axis sound sources. Features: Exceptionally low inherent self-noise Transformerless and fully floating balanced output Infra-sonic cut-off filter Symmetrical transducer technology ensures extremely low distortion Switchable pre-attenuation, switchable roll-off filter and switchable treble emphasis Rugged and weather-proof Black, anodised light meter casing Supply schedule: 1 MKH 70 Technical Data: Pick-up pattern: super cardioid/ lobar Frequency response: 50- 20,000 Hz Sensitivity (free field, no load) (1kHz): 50 (15) mV/Pa Nominal impedance: 150 ohms Min. terminating impedance: 1000 ohms Equivalent noise level A-weighted (DIN IEC 651) CCIR weighted (CCIR 468-3): 8 (15) dB 20(26) dB Max. sound pressure level: 123 (133) dB at 1 kHz Power supply: phantom 48 +/-4 V Supply current: 2 mA Dimensions in mm: O25 x 410
