ATND971

Cardioid Condenser Boundary Microphone with Dante™ Network Output

Features

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.
