CARDIOID CONDENSER HANGING MICROPHONE
natural_image
Close-up of a black mechanical hook or connector with a textured end and threaded shaft (no text or symbols visible)- Available in two colors: black (U853A / U853R) and white (U853AW / U853RW).
The U853A requires 11V to 52V DC phantom power or a 1.5V AA battery for operation. A battery need not be in place for phantom power operation.
Alkaline batteries are recommended for longest life. Remove the battery during long-term storage.
The U853R requires 11V to 52V phantom power operation only.
A uniform 120^ angle of acceptance provides well-balanced audio pickup. The microphone should be located forward of the front-most source, above the rear-most source, and "aimed" between them (Fig.1). Increasing the height of the mic above the sources will tend to equalize sound levels between them, but may also increase from the mic to the rear-most pickup should be no more than twice the distance to the front source, to maintain front-to-rear balance (Fig.1).
Width of pickup is approximately three times the distance to the closest performer. If additional mics are needed for wide sources, they should be positioned apart laterally at least three times the distance to front source, to avoid phase cancellation (Fig.2).
To orient the microphone in the proper direction, twist the housing slightly in its wire holder. (Clockwise rotation moves the microphone to the right; counterclockwise rotation moves it to the left.)
Output from the power module's XLRM-type connector 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.
At integral 80 Hz high-pass UniSteep ^® 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 traffic, air-handling systems, etc.), room reverberation and mechanically coupled vibrations.
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.

心形指向性悬挂式电容话筒
natural_image
Close-up of a black mechanical hook with coiled ends and a textured tip (no text or symbols visible)- 不显眼的设计，并涂上低反光的颜色涂料。
- 设有两种颜色选择 : 黑色 U853A / U853R ，及白色 U853AW / U853RW。
U853A话筒使用 直流11V 至52V 幻象供电或一枚1.5V AA 3号电池供电操作，当使用幻象供电时，可不用安装电池。
建议使用硷性电池工作，当长期不使用电池时，请把电池取出。
U853R话筒只作 直流11V至52V幻象供电操作。
标准配置为心形指向，收音角度可为 120^ 。话筒安装时，应先决定最前及最后的声源位置，而话筒应瞄准两者之间的中央位置(图1)，然后提升话筒高度，使前后声源趋向平衡；但却可能会增加背景噪音声及回声，所以调校话筒时，应避免最后的声源距离长于最前声源的两倍(图1)，以维持前后平衡。
而与其他话筒的宽度距离，应以最前声源的大致三倍距离为最佳设定(图2)，这样做既可覆盖每点声源，又可避免话筒的相位互相抵消情况出现。
话筒附有一条悬挂弹簧，可将收音头固定调校到任何正确位置。(把收音顺时针转动，话筒会向右转；反时针转动时，话筒会左转)
低阻抗的平衡音频输出，话筒音频信号最终以卡农公头的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。
内置高质量高通滤波电路，可由平直的频率响应，开启为于 80 Hz 以下衰减的收音效果，应高通滤波器可减低收音环境中低频噪声（如外间汽车引擎声，空调系统的风声等），房间中的回声及机械性的震动声。
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^ 的地方，而极高湿度也应避免。
