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 BP4027 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 BP4027 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 BP4027 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 BP4027 requires 11V to 52V DC phantom power on Pins 2 and 3
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.

立体声超指向性话筒
- 专为广播,影视拍摄和录音师而设计 。
- 小型及轻重的结构,是用于摄像机挂件的理想配置 。
- 内置独立的超指向性,和 8字形指向性收音头。
- 设有高通滤波开关,有效降低环境中低频噪声 。
- 可选择非矩阵的M-S模式,或两种内置矩阵的左右立体声模式 。
中声道/边声道操作:在M-S模式中,BP4027 话筒提供独立的中
声道和边声道信号,可在现场矩阵调音,或在后期制作时作灵活
广阔的立体声音像调制。
矩阵立体声操作: BP4027 话筒内置两种立体声矩阵设定,提供
传统的左右声道立体声信号输出,而不需特别配置矩阵调音器。
为配合不同的音像环境,话筒设有宽指向的立体声矩阵和窄指向
的立体声矩阵选择,提供广阔或细小音像环境。输出相位将以正
相位电平设于 2号针脚上。
为取得正确的左右立体声定位,需把话筒上的 "UP" 文字向上,而
开关向下。在所有模式中,应把 BP4027 接近音源,以减少回音
混响和提高立体声收音效果。远离音源时会收窄立体声音像和增
加“房间回声”混响。

组 的XLR3M 2 号及3号针脚输出端子上,可使用调音台上的幻象电
源,也可以使用鐵三角的 单通道或 四通道幻象电AT8801 AT8506
源供电器作独立供电。
低阻抗的平衡音频输出,音频信号以卡农公头输出端子的 2号及 3
号针脚输出,而 1号针脚则为地线 (屏蔽)连接。输出相位将以正相
位电平设于 2号针脚上。如连接到非平衡器材,必须配合高质量
的平衡转换变压器使用。
话筒符合 RoHS规格,在构造上不含有欧盟禁用的危害性物质。
把话筒暴露于高温中可能导致输出电平逐渐及永久性减弱,应避
免将话筒留在日晒的地方或长时间置于温度超过 43°C的地方,而
极高湿度也应避免。
