The Audio-Technica BP4029 is a compact 236 mm stereo shotgun microphone using an MS (Mid-Side) arrangement with independent line-cardioid and figure-of-eight elements. The shorter body makes it ideal for camera-mounted use, while switch-selectable internal matrixing provides wide or narrow stereo output, or discrete M/S signals for post-production flexibility.
