Overview

ATND931a

With its low-profile and rugged-yet-highly-flexible design, the ATND931a condenser gooseneck microphone is a perfect fit for boardrooms, school and government settings, teleconferencing, houses of worship and other installed applications. The microphone, which features UniGuard® RFI-shielding technology for outstanding rejection of radio frequency interference (RFI), attaches to the provided ATND8734a Dante-enabled wall/ceiling plate power module via a special TA3F-type connector designed to optimize RFI immunity.

The power module is equipped with an 80 Hz low-cut UniSteep® filter, three-position input gain level selector (+30 dB, +40 dB, and +50 dB), and a red/green LED status indicator (all controlled remotely via third-party software*). It mounts in a standard metal U.S. 2-gang electrical box, and its RJ45 output jack allows for easy connection to the network via CAT5e (or better) cable. 

The ATND931a also offers plug-and-play compatibility with AES67 networks, including those that utilize Livewire, RAVENNA and Q-LAN AoIP technologies, and has expansive Dante Domain Manager features, including role-based security, cross-subnet routing, SNMP alerts, and more.

Includes a two-stage foam windscreen. Additional interchangeable elements – omnidirectional (360°), cardioid (120°), hypercardioid (100°), and MicroLine® (90°) – are available separately.

Available configurations:

ATND931aC: cardioid polar pattern (120° acceptance angle); low-reflectance black finish.

ATND931aH: hypercardioid polar pattern (100° acceptance angle); low-reflectance black finish.

ATND931aML: MicroLine® polar pattern (90° acceptance angle); low-reflectance black finish.

ATND931aWC: cardioid polar pattern (120° acceptance angle); low-reflectance white finish.

ATND931aWH: hypercardioid polar pattern (100° acceptance angle); low-reflectance white finish.

ATND931aWML: MicroLine® polar pattern (90° acceptance angle); low-reflectance white finish.
