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.
This phantom-powered cardioid condenser boundary microphone features a 5-pin XLR output connector with a
touch-sensitive capacitive-type user switch for enhanced control in conference and boardroom installations. Not only
can the switch be configured to toggle between mute and live audio, but, with the microphone’s external contact
closure, it can also be set up to trigger an external device, such as a camera or the room’s lighting.
Designed for clear, highly intelligible conferencing, recording, monitoring and other demanding sound pickup
applications, the ES947CFM5 mounts unobtrusively in tabletops or panels, but includes a highly visible two-state RGB
LED ring (7 selectable colors + OFF) to indicate mute status.
The microphone’s cardioid polar pattern provides 120° coverage. A rugged all-metal case with a two-layer steel mesh
grille protects the microphone element, while our UniGuard® RFI-shielding technology provides outstanding rejection of
radio frequency interference (RFI).
The ES947C/FM5 is equipped with a self-contained power module, eliminating the need for an external one, 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.

品。请妥善保存本手册，以供将来参考。
■说明
ES947C/FM5 心形指向性电容式界面话筒配备了5针 XLRM 型输出连接器和一个电容感应
式轻触开关，可增强对会议室装置的控制。不仅可以将开关设置为在控制话筒静音和收音
之间的切换，还可以通过话筒的接点闭合来触发外部设备，例如摄像头或房间的照明系统
。
采用不显眼设计，可以安装在桌面或控制面板上，以提供最佳的隐藏性，提供清晰而通透
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，而话筒顶部设有可见度
高的双态式 RGB LED 灯环（7种可选颜色 + 关灯），能显示开启/静音状态。
话筒采用坚固的全金属外壳和两层穿孔保护网格，其心形指向性模式提供了120°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。
ES947C/FM5 内置 XLRM 型输出连接器的独立供电模组，从而无需外部电源元件。话筒配
备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
■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。
