With its low profile and rugged yet highly flexible design, The ATND931WC cardioid 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 ATND8734 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.

This gooseneck mic provides a uniform cardioid polar pattern with 120° acceptance angle, comes with a two stage foam windscreen and is available with low reflectance black (ATND931C) or white (ATND931WC) finish. Additional interchangeable elements – omnidirectional (360°), hypercardioid (100°) and MicroLine® (90°) – are available separately.

Wall/ceiling plate power module with Dante™ network output permits permanent installation in standard, 2 gang electrical box and direct connection to the network via Ethernet cable

Uniform cardioid polar pattern with 120° acceptance angle

Low profile design with low reflectance finish for minimum visibility

Superior off axis rejection for maximum gain before feedback

Logic input accepts external switches for connection to the Dante network

UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)

UniSteep® filter provides a steep low frequency attenuation to minimize pickup of undesired ambient noise

Rugged, easy to adjust, small diameter gooseneck can be positioned quickly into desired shape

Available interchangeable elements permit angle of acceptance from 90° to 360°

Ideal for boardrooms, school and government settings, teleconferencing, houses of worship and other installed applications

Available in two colors: black (ATND931C) and white (ATND931WC)
