Thank you for purchasing this product. Before using the product, read through the user manual to ensure that
you will use the product correctly.
Please keep this manual for future reference.
With its low-profile design that mounts unobtrusively in tabletops, ceilings or panels for minimum visibility, the
ES945WO/XLR omnidirectional condenser boundary microphone provides clear, highly intelligible audio that is
perfect for conferencing, recording, monitoring and other demanding sound pickup applications.
Protected by a rugged all-metal case with a two-layer perforated grille, the microphone’s omnidirectional polar
pattern affords a 360° pickup angle, while its UniGuard® RFI-shielding technology provides outstanding
rejection of radio frequency interference (RFI). The microphone also offers IPX4 water resistance to protect it
from splashes of water.
The ES945WO/XLR is equipped with a self-contained power module with an XLRM-type output connector,
eliminating the need for an external power module. The integral power module can be powered from any
external 11V to 52V DC phantom power supply.
The microphone is white colour, and comes with a pair of rubber isolators for optional mechanical isolation from
the mounting surface.
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.
Connect the output terminals of the microphone to a device that has a microphone input (balanced input)
compatible with a phantom power supply. The output connector is an XLRM-type with polarity as shown in the
figure below.
For product improvement, the product is sublect to modification without notice.

■说明
ES945WO/XLR 全指向性电容式界面话筒采用不显眼设计，可以毫不费力地安装在桌面、
天花板或控制面板上，以提供最佳的隐藏性，可作清晰而通透的收音，非常适合会议、
录音、监听和其他要求苛刻的收音应用。
话筒采用坚固的全金属外壳和两层穿孔保护网格，其全指向性模式提供了360°的收音角
度，而话筒配有 UniGuard® RFI 屏蔽技术可以有效地抑制射频干扰。ES945WO/XLR 还
具有 IPX4 防水功能，可防止被水溅进内部。
ES945WO/XLR 配备了带有 XLRM 型输出连接器的独立供电模组，从而无需外部电源元件
，供电模组使用直流 11V 至 52V 幻象供电。
话筒为白色外观，并配有一对橡胶防震垫片，用于可阻隔安装表面的机械式振动。
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。
■连接步骤
将话筒的输出端子连接到具有兼容幻象电源的话筒输入（平衡输入）的设备。输出接口是
XLRM 型接口，其极性如下图所示。
