STEREO SHOTGUN MICROPHONE
- Designed for broadcasters, videographers and sound recordists.
- Compact, lightweight design is perfect for camera-mount use.
- Independent line-cardioid and gure-of-eight condenser elements.
- Switchable low-frequency roll-o.
- Switch selection of non-matrixed M-S mode and two internally-matrixed
left/right stereo modes.
MID-SIDE OPERATION: In M-S mode, the BP4029 provides independent
Mid and Side signals. This allows the width of the stereo image to be
adjusted in post production or in the eld with a matrix mixer.
MATRIXED STEREO: The BP4029 oers two internally-matrixed modes
which provide traditional “left-right” stereo without the need for external
mixers. To accommodate varying acoustic environments, the user may
select between a “wide” pattern (LR-W) with increased ambient pickup,
and a “narrow” pattern (LR-N) which oers more rejection and less
ambience. Output phase is “Pin 2 hot.”
For correct left-right stereo orientation, position the microphone so the
word “UP” is on top, with the switches on the bottom. In all modes,
locating the BP4029 nearer the sound source enhances the apparent
width of the stereo image, while decreasing room ambience. Moving
away from the sound source will result in a narrower stereo image and
more “room sound.”

The BP4029 requires 11V to 52V DC phantom power on both XLR3M
connectors. Wiring must be balanced throughout, and all mic cables in
the system must be wired consistently: Pin 1-to-Pin 1, etc. If connecting
to unbalanced inputs, good-quality balanced line transformers must be
used.
The microphone is RoHS compliant–free from all substances specied in
the EU directive on hazardous substances.
Avoid leaving the microphone in the open sun or in areas where
temperatures exceed 43° C for extended periods. Extremely high humidity
should also be avoided.
