Description
The ATND971 is a Dante-enabled, wide-range condenser microphone with a cardioid polar pattern. It is designed
for surface-mount applications such as high-quality sound reinforcement, conferencing, distance learning and other
demanding sound pickup applications.
The microphone features a touch-sensitive capacitive-type user switch with integral red/green LED status indicator.
In Local mode the user switch mutes and unmutes the microphone. It can be set to toggle between live and muted
audio (toggle on/off), to permit live audio only while the switch is pressed (press to talk), or to mute the audio
while the switch is pressed (press to mute). In Remote mode the user switch can be used to trigger functions on
compatible Dante-enabled devices, such as a video camera’s pan/tilt or a room’s lighting preset. While in Remote
mode the microphone’s audio output is controlled remotely.
The audio output of the ATND971 can be routed using Audinate’s Dante Controller, which is available for download
at the Audinate website (www.audinate.com). The site also provides Dante routing and software instructions.
The microphone is equipped with UniGuard
®
RFI-shielding technology, which offers outstanding rejection of radio
frequency interference (RFI).
The microphone’s cardioid polar pattern provides a 120° angle of acceptance (cardioid in hemisphere above
mounting surface). Additional interchangeable elements with omnidirectional (360°) and hypercardioid (100°) pickup
patterns are available.
Operation and Maintenance
The ATND971 is powered by network PoE. The electronics in the microphone take up
to 30 seconds to stabilize after power is applied.
The microphone should be placed on a at, unobstructed mounting surface, with the
front of the microphone facing the sound source. The sound source should not be
below, or higher than 60° above, the plane of the mounting surface.
The microphone features a touch-sensitive user switch with integral red/green LED status indicator. The user switch
has four Local settings that can be chosen by pressing the button beneath “SWITCH FUNCTION” and “DEFAULT
MODE.” The default setting is TOGGLE ON/OFF. Press the button once to change setting to TOGGLE ON/OFF. In both
settings the user switch will toggle between mute and unmute – the only difference is the status of the audio when
the microphone is turned on. Press the button a second time to select MOM. ON (momentary on), wherein the audio
will be on only while the user switch is being pressed (press to talk). Press the button a third time to select MOM.
OFF (momentary off), wherein the audio will be muted while the user switch is being pressed. Press the button a
fourth time to cycle the setting back to the default. The “SWITCH FUNCTION” and “DEFAULT MODE” LEDs will
illuminate red or green to indicate the current setting.
Turn the low-cut UniSteep
®
lter on and off by pressing the button beneath “LOW CUT” on the bottom of the
microphone. The lter is off by default. The LED above “LOW CUT” illuminates red when the lter is off, green when
it is on.
There are three input gain levels that can be selected: +30 dB (for loudest voices), +40 dB and +50 dB (for softest
voices). To adjust the gain level, press the button beneath “GAIN” on the bottom of the microphone. Pressing the
button once changes the level from +30 dB to +40 dB, pressing it again changes the level to +50 dB and pressing a
third time returns the level to +30 dB. The LED above “GAIN” illuminates green for +30 dB, orange for +40 dB and
red for +50 dB.
To lock the Local settings, press and hold the button beneath “LOCK” on the bottom of the microphone. Press and
hold again to unlock settings. The LED above “LOCK” will illuminate red when locked and remain unlit when not
locked. If a setting button is pressed while the lock is on, the LOCK LED will blink.
All LEDs on the bottom of the microphone will turn off seven seconds after the last button is pressed. Pressing any
button will cause the LEDs to relight.

To return the microphone to its default Local settings, press the GAIN and LOW CUT buttons simultaneously.
The microphone can also be controlled remotely via third-party software.* When this software is used it will
override local control, causing the audio to remain on and the red/green LED status indicator, low-cut lter and input
gain level to be controlled remotely. In Remote mode the microphone’s user switch can be programmed to trigger
functions on compatible Dante-enabled devices. When in remote mode the Remote LED is illuminated.
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.

说明
ATND971是一枚具有Dante功能，宽阔频宽的电容式心形指向性界面话筒，设计于平面放
置应用，提供高质量收音、会议、远程教学等高要求的收音应用。
话筒设有电容感应轻触开关，并设置有以红/绿色显示LED指示灯。在本地模式下，用户可
开关话筒以静音或讲话操作，当中可以设置讲话和静音间的反覆切换 (锁存式开/关)之间的
实时和静音音频切换；或预设静音而只在按下时讲话(点动讲话)，或预设讲话而只在按下
时静音(点动静音)。在远程模式中，轻触开关可用来控制兼容Dante功能的设备，例如视频
摄像机的拍摄目标位置或房间的照明预置功能。同时话筒的音频输出亦可在远程模式中作
出远端控制。
ATND971的音频输出可以使用Audinate公司的Dante控制器作路线布局，可在Audinate网站
(www.audinate.com)下载有关软件。该网站还提供Dante的路由控制和软件说明。
话筒配备有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。
话筒的心形指向性提供120°的收音角度(平面上的心形半圆)，并可选配其他适合的收音头
配合实际的应用，包括全指向性360°、超心形指向性100°。
操作与维护
ATND971需要由网络的PoE供电。话筒的电子部份需要在上电30秒后
才达到稳定的状态。
话筒应放置在平面上，及没有阻碍物的环境使用。音源应在话筒的
前方发声，理想的收音角度应在平面至60°高度之内。
话筒配置有一个整合式的轻触感应用户开关，和红/绿色LED状态指示灯。此用户开关设有
四组设置选择，可以通过按下底部的按钮选择“开关功能(SWITCH FUNCTION)”和“默认模
式(DEFAULT MODE)”。在预设状态下为“锁存开关模式 (TOGGLE ON/OFF)”，按下一次可按
钮来更改更默认模式，两种模式同样是设置用户开关在静音和讲话间的反覆切换 - 唯一的
区别只是在话筒上电时的音频状态。再按下第二次，会设置为“点动开启模式(MOM.ON)”,
话筒正常时为静音，只在按下用户开关时才开启讲话 (按下讲话)。再按下第三次，会设
置为“点动关闭模式(MOM.OFF)”,话筒正常时为开启，只在按下用户开关时才会关闭静音
(按下静音)。当再按下第四次时，会恢复到周期设置的预设状态。在“开关功能(SWITCH
FUNCTION)”和“默认模式(DEFAULT MODE)”的指示灯会亮起红色或绿色来显示当前设置。
话筒配置有UniSteep® 高通过滤器开闭，可按下话筒底部的“LOW CUT”按钮选择。该过滤
器预设是关闭的，即“LOW CUT”的LED会亮起红色；而在选择于开启状态时，LED会亮起
绿色显示。
另外，话筒亦配置有三种输入增益选择，亦即是 +30dB (在大音量讲话)、+40dB 和
+50dB (用于柔弱的音量)。要调整增益电平，可按下话筒底部的“GAIN”按钮。按下一次
可把级别从 +30dB 改至 +40dB，再按第二次会把增益改变至 +50dB，如再按第三次会把
增益电平返回+30dB。上述“GAIN”的LED会分别以绿色(+30dB)，橙色(+40dB)和红色
(+50dB)显示。
如要锁定本地设置，可持续按下话筒底部的“LOCK”按钮，再次持续按下可解除锁定。当
锁定时，“LOCK”的 LED会显示红色；而在未锁定时会保持熄灭。当锁定时如果按下其他
按钮，LOCK指示灯会闪烁显示。
在最后一之按下按钮后，话筒底部的所有LED将会保持7秒后关闭，直至再按下任何按钮
后，LED指示灯才重新亮起。

把话筒的本地模式恢复回默认预设状态，可同时按下“GAIN”和“LOW CUT”按钮即可。
话筒也可以通过第三方软件进行远程控制。*在使用这些软件时，软件将会无视本地控制的
设定，从而使音频维持开启，而LED指示灯的红/绿状态、高通滤波器和输入增益均由远程
控制所取代。在远程模式时，话筒上的用户开关可以被编程为控制其他兼容Dante设备的
操作。在操作于远程模式时，远程(Remote)LED将亮起显示。
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。
