  • Overview


    With its low-profile and rugged-yet-highly-flexible design, the ES931PMH hypercardioid 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 hypercardioid polar pattern with 100° acceptance angle, comes with a two-stage foam windscreen and is available with low-reflectance black (ES931PMH) or white (ES931PMWH) finish. Additional interchangeable elements – omnidirectional (360°), cardioid (120°) and MicroLine® (90°) – are available separately.

  • Q & A

    Good Day, We have a lecture hall renovation under construction at the State University of New York "ESF" campus . The teaching wall is focused on a 20' W chalkboard, underneath a same-size rear-projection glazing. the Hall seats roughly 155 students in (9) rows. The room is 52 feet wide x 45 feet deep. would you have any concerns mounting an ES931PMH on the ceiling, 12 feet above the floor at the teaching wall (and 8 1/2' feet above the floor at the back of the room)? How far back from the teaching wall would you recommend installing it? Thank you Andrew M. Gil, AIA Associate, Project Manager

    Andrew
