Pro broadcast 380mm stereo M-S shotgun
Based on models originally developed for use in the broadcast of the Sydney Olympics in 2000, the BP4027 (14.96″ long) and BP4029 (9.29″ long) Stereo Shotgun models are engineered for high-end broadcast and production use. Both microphones feature independent line-cardioid and figure-of-eight elements configured in an MS (Mid-Side) arrangement with switch-selectable internal matrixing. These innovative microphones allow 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.
