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 trac, 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 dierence 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.
