Description
The ATND8677 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/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 desk stand's audio output is controlled remotely.
The audio output of the ATND8677 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 low-reflectance black finish.
Operation and Maintenance
The ATND8677 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. 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 desk stand 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
®
filter on and off by pressing the button beneath “LOW CUT” on the bottom of the
desk stand. 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 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 12V DC of phantom power, which is required by most gooseneck
microphones. Phantom power can be turned off 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 off.
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 off 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 and
input gain level 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 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.
