Description

The ATND8734a is a Dante-enabled wall/ceiling plate power module designed for use with gooseneck and hanging microphones that have a TA3F-type connector. The power module is equipped with an RJ45 output jack that allows for easy connection to the network via CAT5e (or better) cable. Additionally, logic input screw terminals accept an external switch for connection to the Dante™ network.

The power module is equipped with an 80 Hz low-cut UniSteep® ﬁlter, threeposition input gain level selector (+30 dB, +40 dB and +50 dB), and red/green LED status indicator, which can all be controlled remotely via third-party software.* Default settings for the power module are as follows: low-cut ﬁlter o, +40 dB input gain, LEDs o.

The ATND8734a features a circular cover plate that can be removed and painted with commercially available spray paint.

Architect’s and Engineer’s Speciﬁcations

The power module shall be of a type that can be mounted to a wall or ceiling. It shall mount in a standard 2-gang metal electrical box and have a removable, circular cover plate. The power module shall have a TB3M-type input connector, designed to work with gooseneck and hanging microphones that have a TA3F-type output connector. The power module’s output connector shall be an RJ45-type with standard network protocol. Logic input screw terminals shall be provided to accept commercially available external switches. The power module shall be capable of driving a Dante audio ﬂow. The module shall be equipped with a green connection LED that lights when a link is established between the module and another device on the network, and the LED shall blink when data is being transferred between the two.

The power module shall include: an 80 Hz “low cut” switch to tailor the lowfrequency response and minimize pickup of unwanted sounds; three-position input gain control (+30 dB, +40 dB, and +50 dB); and a red/green LED indicator ring. Each of these shall be controlled via third-party software.*

The power module shall be powered by network PoE.

Installation and Operation

The ATND8734a wall/ceiling plate power module is designed to be mounted in a standard metal U.S. 2-gang electrical box. For safety and best performance, use the electrical box only for the ATND8734a; do not include any AC power conductors. Use commercially available screws to mount the power module.

Connect the TA3F-type connector on a gooseneck microphone to the TA3M-type connector on the power module. Use CAT5e (or better) cable terminated with an RJ45 connector to connect the power module to the network.

The power module is equipped with logic input screw terminals which can be used to trigger functions on compatible Dante-enabled devices, such as a video camera’s pan/tilt or a rooms lighting preset.

The power module is powered by network PoE.
