Stereo Shotgun Microphone feature independent line-cardioid and figure-of-eight elements configured in an MS (Mid-Side) arrangement with switch-selectable internal matrixing. It allows sound recordists the choice of selecting a left-right stereo output (wide or narrow) via the mic'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. The BP4027 mic also features a rugged lightweight design and sleek black color scheme, perfect for on-camera use.
Originally, based on models odeveloped for use in the broadcast of the Sydney Games in 2000, the BP4027 mic is 14.96 inches long and is engineered for high-end broadcast and production use.
