The ATND931aWC is a wide-range miniature condenser microphone with a cardioid polar pattern. It is designed for quality sound reinforcement. The small-diameter gooseneck design permits highly flexible positioning while maintaining a smooth, well-contoured appearance. The combination of small size and excellent response makes the microphone ideal for boardrooms, school and government settings, teleconferencing, houses of worship and other installed applications.
The microphone is equipped with UniGuard® RFI-shielding technology, which offers outstanding rejection of radio frequency interference (RFI). The microphone's cardioid polar pattern provides a 120° angle of acceptance. Additional interchangeable elements with omnidirectional (360°), hypercardioid (100°) and MicroLine® (90°) pickup patterns are available.
The microphone's free end connects 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 features a removable, circular cover plate that can be painted with commercially available spray paint. The power module includes an RJ-45 output jack 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, three-position 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 off, +40 dB input gain, LEDs off.
The microphone is enclosed in a rugged housing with a low-reflectance black finish and comes equipped with a wall/ceiling plate power module and a two-stage foam windscreen. The microphone is also available with black housing and windscreen as the ATND931aC.
