Audio-Technica BP4001 Cardioid Dynamic Interview Microphone
The BP4001 is a cardioid dynamic microphone built specifically for on-location interviews, ENG, EFP, and sports reporting, where clear and articulate speech matters more than studio nuance. Its cardioid pattern reduces pickup from the sides and rear, isolating a reporter's or subject's voice from crowd noise and wind on a busy sidewalk or sideline.
The back-cavity assembly floats inside the handle shell, a design that decouples the capsule from the body so handling noise, taps, bumps, cable jostling, doesn't make it into the signal. It's built to withstand the abrasion and knocks that come with daily field use, and it ships ready to work: a slip-on foam windscreen, vinyl carrying case, soft protective pouch, and a professional stand clamp are all included.
