The Audio-Technica BP4073 Lightweight Shotgun Microphone is well suited for capturing speech and audio in feature film recording, broadcast and theater sound reinforcement applications. The microphone measures just 9.17" in length, and weighs 3.5 oz making it ideal for long-term use on the ends of boompoles and handheld mounts.

Its wide frequency response, Line + Gradient pick up pattern and low noise result in transparent audio reproduction. An 80Hz hi-pass filter switch minimizes low-frequency noise and ambiance, while the 10dB pad switch provides added headroom when capturing transient (peak) audio signals. The BP4073 is RoHS compliant, providing RF (radio-frequency) interference free operation.
