Audio-Technica BP4029 9.3in Stereo Shotgun Broadcast Production Microphone

Based on models originally developed for use during the broadcast of the Sydney Games in 2000, the Audio-Technica BP4029 9.3in Stereo Shotgun Broadcast Production Microphone is designed specifically for high-end broadcast and production environments. Engineered with precision, this microphone offers exceptional audio quality that meets the stringent demands of professional broadcasters, videographers, and sound recordists. Its compact and lightweight design makes it ideal for on-camera use, while its sophisticated technology ensures superior performance and flexibility.

One of the standout features of the BP4029 is its independent line-cardioid and figure-of-eight elements configured in a Mid-Side (MS) arrangement with switch-selectable internal matrixing. This innovative design allows users to choose between a left-right stereo output (wide or narrow) or discrete Mid-Side signals for post-production manipulation—a level of versatility not available from any other manufacturer. The microphone also includes a switchable low-frequency roll-off filter to minimize unwanted low-frequency noise, enhancing your audio clarity.

Built from rugged materials and finished with a sleek black color scheme, the BP4029 not only looks professional but is also highly durable, ensuring it can withstand the rigors of constant use. Phantom-powered and RoHS compliant, this microphone adheres to international standards for safety and environmental sustainability.
