With its low-profile and rugged-yet-highly-flexible design, the ES931 condenser gooseneck microphone is a perfect fit for boardrooms, school and government settings, teleconferencing, houses of worship, and other installed applications. The microphone is equipped with a special TA3F-type connector that works with compatible Audio-Technica power modules and features UniGuard RFI-shielding technology for outstanding rejection of radio frequency interference (RFI). The mic comes with a two-stage foam windscreen. Additional interchangeable elements - omnidirectional (360°), cardioid (120°), hypercardioid (100°), and MicroLine (90°) - are available separately.
