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/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. 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
desk stand provides 12V DC phantom power by default, which can be
switched off 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/off (with audio muted
at power up), low-cut filter off, +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 low-reflectance 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
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
difference 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
filter,
®
(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
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 12 V 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, 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.
