The Audio-Technica BP4029 Short M-S Stereo Shotgun Mic is a professional 9.3-inch stereo shotgun microphone designed for high-end broadcast and production use.
The Audio-Technica BP4029 Short M-S Stereo Shotgun Mic is a high-performance condenser microphone engineered for professional broadcasters, videographers, and sound recordists. Measuring 9.29 inches in length, this compact shotgun microphone provides exceptional audio capture for high-end production environments. The design originates from models developed for major international broadcast events, ensuring reliable performance in demanding field conditions.
This microphone utilizes an innovative Mid-Side (M-S) arrangement featuring independent line-cardioid and figure-of-eight condenser elements. This configuration allows the Audio-Technica BP4029 to capture accurate spatial imaging and provide flexible output options. The system supports discrete Mid-Side signals, giving recordists the ability to manipulate the stereo width during later production stages.
The Audio-Technica BP4029 includes an internal matrixing system with a switch-selectable interface. Users can choose between a non-matrixed M-S mode or two different internally-matrixed left-right stereo modes. The matrixed options provide a choice between wide and narrow stereo images, allowing the microphone to adapt to various recording environments and subject distances without external processing.
A switchable low-frequency roll-off filter helps maintain audio clarity by minimizing the pickup of unwanted ambient noise. This feature effectively reduces low-end interference in unpredictable recording locations. The microphone operates on phantom power, delivering consistent performance for professional recording hardware and camera systems.
Constructed for on-camera applications, the Audio-Technica BP4029 features a rugged yet lightweight housing. The sleek black color scheme ensures the microphone remains unobtrusive during filming. Its compact size makes it an ideal choice for camera-mount use where space and weight are critical factors.
The package includes a 0.61-meter (24-inch) cable equipped with a 5-pin XLRF connector to two standard 3-pin XLRM connectors, ensuring immediate compatibility with professional audio interfaces. The Audio-Technica BP4029 is RoHS compliant and free from hazardous substances specified in EU directives.
