MicroLine® Condenser Gooseneck Microphone

Overview

With its low-profile and rugged-yet-highly-flexible design, the ES931PMML MicroLine® 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 MicroLine® polar pattern with narrow 90° acceptance angle, comes with a two-stage foam windscreen and is available with low-reflectance black (ES931PMML) or white (ES931PMWML) finish. Additional interchangeable elements – omnidirectional (360°), cardioid (120°) and hypercardioid (100°) – are available separately.
