CARDIOID CONDENSER QUICK-MOUNT
GOOSENECK MICROPHONE
- Designed for high-quality sound
reinforcement, professional
recording and broadcasting.
- Superior off-axis rejection for
maximum gain before feedback.
- UniGuard™ RFI-shielding
technology offers outstanding
rejection of radio frequency
interference (RFI).
- Easy-to-adjust, rugged, small-
dimeter, alternating gooseneck with
virtually no “memory” permits quick
positioning into desired shape.
- UniSteep® lter provides a steep
low-frequency attenuation to
improve sound pickup without
affecting voice quality.
- Self-contained electronics eliminate
need for external power module.
- Accepts interchangeable elements
to permit angle of acceptance from
90° to 360°.
- Two-stage foam windscreen yields
dramatically improved resistance to
P-pops and other breath blasts.
- Quick-mount design with 3-pin
XLRM-type connector insert at base
plugs into any standard XLRF-type
surface or cable connector.
- Optional shock mount attenuates
noise, shock and vibration
transmitted through the mounting
surface.
The U857Q stands 365mm from the table or podium, it is also
available in a 419mm version as U857QM and 481mm version
as U857QL. The three models are identical in all other respects
and require 11V to 52V phantom power for operation.
Output from the microphone's XLRM-type connector is low
impedance (Lo-Z) balanced. The signal appears scross 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 at frequency response to a low-end roll-off.
The roll-off position reduces the microphone's sensitivity to
popping in close vocal use. It also reduces the pickup of low-
frequency ambient noise (such as trafc, air-handling systems,
etc.), room reveberation and mechanically coupled vibrations.
Avoid leaving the microphone in the open sun or in areas where
trmperatures exceed 43°C for extended periods. Extremely high
humidity should also be avoided.

心形指向性 快速安装式
专业型鹅颈式会议话筒
- 设计于高质量收音、专业录音、电
视广播、会议等高要求的收音应
用。
- 良好的隔音设计，在最大增益时仍
能避免啸叫声的出现。
- UniGuard™ - 射频干扰(RFI)屏敝
技术，提供杰出的防止射频干扰
能力，避免收音时受到如手提电
话等的干扰。
- 易于调节、耐用、细小、可反覆摆
动而没有“记忆”效果的鹅颈弯
曲结构，可快速及随意地把话筒
收音头固定在合适的位置。
- UniSteep® - 高通滤波器，提供了
一个高效能的高通滤波，把低频
噪声作出衰减而无损话音的收音
质量。
- 内置话筒前置放大器供电组件，无
需使用外置供电模组。
- 更换式的收音头设计，可选配适合
的收音头配合实际的应用，收音
角度可由90 °至360°。
- 附有双层式防风海棉罩，可减低在
讲话时收到不雅的喷气声及其他
风声的情况出现。
- 快速安装设计，在话筒接线端为标
准的 3针卡农公头 XLRM，可连接
到以 任 何以 3针卡农 母头X LR F设
计的会议话筒座上，亦可在有需
要时直接连线到调音台上。
- 可选配桌面防震话筒座，把话筒固
定安装在桌面或其他板面上，并
能减低碰撞平面时产生的敲击声
及震动声。
U857Q 全长为365mm，可安装在桌面或控制板上使用。另外，
U857QM 全长为419mm和U857QM 全长为481mm，而三个型号
的其他细节均相同，并同样以直流 11V 至52V 幻象供电工作。
低阻抗的平衡音频输出，音频信号以卡农公头的 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 UniSteep® 高通滤波电路，可轻易由平直的频率响
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

声(如外间汔车引擎声，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°C的地方，而
极高湿度也应避免。
