Description
The ATND8677a is a Dante-enabled microphone desk stand for use with any
gooseneck microphone with a three-pin XLRM-type output connector. The desk stand
is designed for surface-mount applications such as high-quality sound reinforcement,
conferencing, distance learning and other demanding sound pickup applications.
The desk stand 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/
o), 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
desk stand’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-o. The
roll-o position reduces the pickup of low-frequency ambient noise (such as trac,
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 desk stand provides 12V DC phantom power by default,
which can be switched o and on.
The gain, low-cut UniSteep® filter, red/green LED status indicator and phantom power
can all be controlled locally or remotely via third-party software.* Recessed buttons
on the bottom of the desk stand allow user to configure the desk stand settings
locally. Audio, low-cut, gain and phantom power 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 stand are as follows: audio toggle on/
o (with audio muted at power up), low-cut filter o, +30 dB input gain, phantom
power on.
The audio output of the ATND8677a 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 desk stand’s heavy die-cast case and non-slip silicone foam bottom pads
minimize coupling of surface vibration to the microphone. The stand features a lowreflectance black finish.
Installation and Operation
The ATND8677a is powered by network PoE.
The electronics in the desk stand take up to 30 seconds to stabilize after
power is applied.
The desk stand 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, input gain level and phantom power—can be adjusted by
pressing the appropriate recessed button on the bottom of the desk stand.
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 dierence is the status of the audio when the
desk stand 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 o), 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 o by pressing the button beneath “LOW
CUT” on the bottom of the desk stand. The filter is o by default. The LED above
“LOW CUT” illuminates red when the filter is o, 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 desk stand. 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.
By default, the desk stand supplies 12 V DC of phantom power, which is required
by most gooseneck microphones. Phantom power can be turned o by pressing
the button beneath “PHANTOM” on the bottom of the desk stand. The LED above
“PHANTOM” illuminates green when power is on and red when it is o.
To lock the Local settings, press and hold the button beneath “LOCK” on the bottom
of the desk stand. 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 desk stand will turn o seven seconds after the last
button is pressed. Pressing any button will cause the LEDs to relight.
To return the desk stand to its default Local settings, press the GAIN and LOW CUT
buttons simultaneously.

The desk stand 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 filter, input gain level and phantom
power to be controlled remotely. In Remote mode the desk stand’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 desk stand in the open sun or in areas where temperatures exceed
110° F (43° C) for extended periods. Extremely high humidity should also be avoided.
Note: Placing any object on a surface (such as a conference table) before its finish is
fully cured may result in damage to the finish.

connector and an RJ45 type output connection using standard network protocol.
It shall have a frequency response of 20 Hz to 20,000 Hz. An 80 Hz “low cut”
switch shall be provided to tailor the low-frequency response to minimize pickup
of unwanted sounds; it shall be selectable both locally and remotely via third-party
