Audio-Technica BP4001 Cardioid Dynamic Microphone
The Audio-Technica BP4001 is a handheld cardioid dynamic microphone tailored for clear, articulate reproduction of the spoken word, made for on-location interviews, ENG, EFP, and sports broadcasting.
Its back-cavity assembly floats inside the handle shell, isolating the element from handling noise. The cardioid pattern reduces pickup from the sides and rear, which helps cut unwanted sound and control feedback. An integral windscreen protects against wind and breath noise, and the rugged housing with a hardened-steel grille stands up to field use.
The extended handle leaves room for a mic flag. The balanced, low-impedance output comes from an integral 3-pin XLR connector, and the BP4001 works in the hand or on a stand. It is also available with an omnidirectional pattern as the BP4002.
The included AT8470 Quiet-Flex stand clamp fits 5/8″-27 threaded stands. A 5/8″-27 to 3/8″-16 threaded adapter, a foam windscreen, a carrying case, and a soft protective pouch are also included. The BP4001 is 240.8 mm (9.48 inches) long and weighs 275 g (9.7 oz).
