Audio-Technica BP4071 Line Gradient Condenser Microphone

For location sound, broadcast, film/TV and critical monitoring, the Audio-Technica BP4071 line gradient shotgun microphone delivers focused, professional-grade audio where intelligibility matters most. This Audio-Technica pro microphone uses an innovative interference-tube design to achieve the directivity of mics up to 50% longer while remaining a compact 15.6" — ideal for boom, pistol grip, or fixed security/surveillance mounts. With a low noise floor, transformerless direct-coupled balanced output and a sensitivity of -29 dB, the BP4071 captures clear dialogue and ambient detail across a wide 20 Hz–20 kHz frequency range. The cardioid polar pattern and switchable 80 Hz high-pass filter plus 10 dB pad let engineers control proximity effect, wind rumble and high SPL sources without adding noise. Built in a lightweight structural-grade aluminum housing and backed by a 5-year limited warranty, the BP4071 is suited for theater reinforcement, wildlife recording, on-set boom work and security monitoring installations. Equip your next production or surveillance project with the Audio-Technica BP4071 for reliable, focused audio capture — order now or contact sales for bulk and system integration options.
