The Audio-Technica BP4071 L Shotgun Microphone is one of the longest shotgun microphones in the world at 539 mm, designed to meet the demanding needs of professional broadcast, film, and television. Its extremely narrow directivity makes it ideal for long-distance sound capture in challenging environments like film sets, theaters, or sporting events. With exceptional rejection of side and rear noise, this microphone ensures perfect intelligibility, even in noisy surroundings, while capturing all frequencies from 20 Hz to 18 kHz.
Equipped with the proprietary "Double Wave Diaphragm" technology, the BP4071L offers high sensitivity and low self-noise, delivering a clean, balanced signal even in high-output conditions. It includes a switchable 80 Hz low-cut filter to minimize unwanted low-frequency noise and a -10 dB attenuator for added versatility. The robust design, made from lightweight aluminum alloy, is durable and resistant to mobile phone interference. Included accessories like a foam windscreen, clip, and protective carry case ensure maximum functionality and convenience.
