  • Overview


    With its low-profile and rugged-yet-highly-flexible design, The ES931PMC 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 AT8534 wall/ceiling plate power module via a special TA3F-type connector designed to optimize RFI immunity.

    Switches in the power module permit a +10 dB gain setting for extra sensitive pickup as well as a choice of flat response or low-frequency roll-off (via integral 80 Hz high-pass UniSteep® filter) to help control undesired ambient noise. The power module mounts in a standard metal U.S. single-gang electrical box.

    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 (ES931PMC) or white (ES931PMWC) finish. Additional interchangeable elements – omnidirectional (360°), hypercardioid (100°) and MicroLine® (90°) – are available separately.
