Description
The ATND971a 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. An integral
80 Hz low-cut UniSteep® filter provides easy switching from a flat frequency response
to a low-end roll-off. The roll-off position reduces the pickup of low-frequency
ambient noise (such as traffic, air-handling systems, etc.), room reverberation and
mechanically coupled vibrations. A three-position input gain level selector permits
trim adjustment to accommodate louder and softer voices.
The gain, low-cut UniSteep® filter and red/green LED status indicator can all be
controlled locally or remotely via third-party software.* Recessed buttons on the
bottom of the microphone allow user to configure the microphone settings locally.
Audio, low-cut and gain settings can be locked in Local mode by pressing and
holding the lock button. This lock will prevent end users from adjusting the settings.
Default settings for the microphone are as follows: audio toggle on/off (with audio
muted at power up), low-cut filter off, +30 dB input gain.
The audio output of the ATND971a 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.
The microphone’s heavy die-cast case and non-slip silicone foam bottom pads
minimize coupling of surface vibration to the microphone. The microphone includes a
soft protective pouch and features a low-reflectance black finish.
Installation and Operation
The ATND971a 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 flat,
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. In Local mode, which is the default, the user switch mutes
and unmutes the audio. The Local mode settings for the user switch – as well as
the low-cut UniSteep® filter and input gain level – can be adjusted by pressing the
appropriate recessed button on the bottom of the microphone.
The user switch has four Local settings (see User Switch Settings and Functions in
Local Mode below) that can be chosen by pressing the button beneath “SWITCH
FUNCTION” and “DEFAULT MODE.” The default setting is TOGGLE ON/OFF (with
audio muted at power up). Press the button once to change setting to TOGGLE
ON/OFF (with audio on at power up). 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 setting 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 setting button a third time to select MOM. OFF
(momentary off), wherein the audio will be muted while the user switch is being
pressed (press to mute). Press the setting 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® filter on and off by pressing the button beneath “LOW
CUT” on the bottom of the microphone. The filter is off by default. The LED above
“LOW CUT” illuminates red when the filter 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.
