BP40
Large-Diaphragm Dynamic Broadcast Microphone
Features
Description
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 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 "-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 "-27
threads. A soft protective pouch is also included.
Installation and Operation
Output is low impedance (Lo-Z) balanced. The signal appears
across Pins 2 and 3; Pin 1 is ground (shield). Output phase is “Pin
2 hot”— positive acoustic pressure produces positive voltage at
Pin 2.
To avoid phase cancellation and poor sound, all mic cables must
be wired consistently: Pin 1-to-Pin 1, etc.
An integral 100 Hz high-pass filter provides easy switching
from a flat frequency response to a low-end roll-off. The roll-
off position reduces the pickup of low-frequency ambient noise
(such as trafc, air-handling systems, etc.), room reverberation
and mechanically coupled vibrations.
To engage the lter slide the switch toward the “bent” line.
Take care to keep foreign particles from entering the windscreen.
An accumulation of iron or steel lings on the diaphragm, and/or
foreign material in the windscreens mesh surface, can degrade
performance.
