Audio-Technica BP4071 Short Videomikrofon

The BP4071 is a professional-grade short line-plus-gradient shotgun condenser microphone developed for broadcast, film, and EFP location sound applications where the highest possible off-axis rejection and low self-noise are required in a compact body. Its transformerless circuit provides extremely low self-noise suitable for distant dialogue pickup and quiet scene ambience recording demanded by professional film and broadcast production standards.

Professional Broadcast Noise Floor

With a self-noise specification of under 10 dB SPL (A-weighted), the BP4071 meets the stringent low-noise requirements of professional film dialogue and broadcast location recording. This low noise floor allows boom operators to work further from the talent while maintaining a clean signal that requires minimal noise reduction in post-production.

Interference Tube Design

The precision-machined interference tube provides high directional selectivity in the mid and high frequencies, concentrating pickup directly on-axis and rejecting ambient noise from the sides. The cardioid element handles the low frequencies below the effective range of the tube, maintaining useful directional control across the full speech bandwidth.

Transformerless Output Circuit

The transformerless output provides wide dynamic range, excellent common-mode rejection, and consistent performance across long cable runs typical of boom pole and plant mic applications. The BP4071 operates on 48V phantom power and connects via standard 3-pin XLR to broadcast mixers, portable recorders, and camera audio systems.
