Overview

ES931

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.

Available configurations:

ES931PMC: cardioid polar pattern (120° acceptance angle); AT8534 wall/ceiling plate power module (+10 dB gain switch, 80 Hz high-pass UniSteep® filter); low-reflectance black finish.

ES931PMH: hypercardioid polar pattern (100° acceptance angle); AT8534 wall/ceiling plate power module (+10 dB gain switch, 80 Hz high-pass UniSteep® filter); low-reflectance black finish.

ES931PMML: MicroLine polar pattern (90° acceptance angle); AT8534 wall/ceiling plate power module (+10 dB gain switch, 80 Hz high-pass UniSteep® filter); low-reflectance black finish.

ES931PMWC: cardioid polar pattern (120° acceptance angle); AT8534 wall/ceiling plate power module (+10 dB gain switch, 80 Hz high-pass UniSteep® filter); low-reflectance white finish.

ES931PMWH: hypercardioid polar pattern (100° acceptance angle); AT8534 wall/ceiling plate power module (+10 dB gain switch, 80 Hz high-pass UniSteep® filter); low-reflectance white finish.

ES931PMWML: MicroLine polar pattern (90° acceptance angle); AT8534 wall/ceiling plate power module (+10 dB gain switch, 80 Hz high-pass UniSteep® filter); low-reflectance white finish.
