Audio-Technica BP4027 15in Stereo Shotgun Broadcast Production Microphone

Audio-Technica BP4027 15in Stereo Shotgun Broadcast Production Microphone

The Audio-Technica BP4027 15in Stereo Shotgun Broadcast Production Microphone is a high-end microphone engineered specifically for professional broadcasting and production use. Originally developed for the Sydney Games in 2000, this microphone has stood the test of time and continues to be a top choice among broadcasters, videographers, and sound recordists. With its innovative Mid-Side (MS) arrangement, the BP4027 offers unparalleled flexibility, allowing users to select between left-right stereo outputs or discrete Mid-Side signals for post-production manipulation.

This 15-inch microphone features independent line-cardioid and figure-of-eight condenser elements, providing precise audio capture. A switchable low-frequency roll-off filter minimizes unwanted low-frequency noise, while its rugged yet lightweight design makes it perfect for camera-mount use. The BP4027 is not just a tool for professionals but a versatile asset in any audio toolkit. It comes with a 0.61 m (24") cable and is RoHS compliant, ensuring it meets all EU directives on hazardous substances.
