    The BP40 is a large-diaphragm dynamic microphone with a hypercardioid polar pattern. It is designed for use as a broadcast vocal microphone.

    The hypercardioid polar pattern of the microphone is more sensitive to sound originating directly in front of the element, making it useful for controlling feedback and reducing pickup of unwanted sounds.

    The output of the microphone is a 3-pin XLRM-type connector. The microphone is equipped with a switch that permits choice of flat response or low-frequency roll-off (via integral 100 Hz high-pass filter).

    The microphone is enclosed in a rugged housing with a multistage windscreen. The capsule is set back from the screen to provide a more consistent response. The included AT8483 mounting clamp fits any microphone stand with ⅝"-27 threads. For improved protection from noise, shock and vibration, the AT8484 shock mount, available separately, may be used in place of the mounting clamp; it likewise fits stands with ⅝"-27 threads. A soft protective pouch is also included.
