The 4071 features a specially designed, fixed microphone grid with a soft presence boost of typically 5 dB at 4 - 6 kHz. Speech intelligibility, clarity and definition of voices and instruments lie within the area that the 4071 grid boosts. While clarity seems to be missing from chest-worn microphone placement, the 4071 will make voices cut through. Typical applications are ENG/EFP use on the reporter in studio or in the field, or film production use, with hidden microphone placements on the actors.
When recording voices from mic placement on a performers body, no frequency below 100 Hz is attractive. For this reason, an acoustical low-cut has been incorporated in the 4071 capsule so the built-in pre amp, and the perhaps following wireless system, will have much larger headroom. Apart from the low-cut feature, type 4071 uses the same prepolarised omnidirectional miniature condenser capsule as its world-famous "brother" 4061. A wide range of connection adapters makes it possible to use the 4071 with most professional wireless system available plus 48 V phantom.
