Audio-Technica BP4001 Cardioid Dynamic Microphone

With its long handle and low handling noise, the BP4001 makes a great handheld interview mic. The cardioid pickup pattern helps zero in on your sound source.

The Audio-Technica BP4001 cardioid dynamic microphone is tailored for extremely clear and articulate reproduction of spoken words. Featuring an extended handle that easily accommodates microphone flags, the BP4001 is ideal for all aspects of broadcast and remote newsgathering: on-location interviews, ENG, EFP, sports applications and much more. Designed to provide exceptional isolation from handling noise, the microphone is ruggedly built to withstand the abrasion and jostling expected with life in the field. The microphone offers a 3-pin XLRM-type output connector and comes generously equipped with a slip-on foam windscreen, vinyl carrying case, soft protective pouch, and professional stand clamp. It is available with an omnidirectional polar pattern as the BP4002.
