Based on models originally developed for use in the broadcast of the Sydney Olympics in 2000, the Audio Technica BP4029 (9.29" long) is engineered for high-end broadcast and production use. It features independent line-cardioid and figure-of-eight elements configured in an MS (Mid-Side) arrangement with switch-selectable internal matrixing. This innovative microphone allows sound recordists the choice of selecting a left-right stereo output (wide or narrow) via the microphone's internal matrixing system or choosing discreet Mid-Side signals for later manipulation, a flexibility not available from any other manufacturer.

A switchable low frequency roll-off filter helps minimize the pickup of unwanted low frequency noise. These phantom-powered models feature a rugged lightweight design and sleek black color scheme, perfect for on-camera use.
