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 at
response or low-frequency roll-off (via integral 100 Hz high-pass lter).
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 ts
any microphone stand with 5/8"-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 ts
stands with 5/8"-27 threads. A soft protective pouch is also included.
