Cardioid Condenser Boundary Microphone with 5-Pin XLR Output and Remote Muting

  • Designed for surface-mount applications such as conferencing, recording, monitoring, and other demanding sound pickup applications
  • Logic I/O capability permits control of remote devices from mic’s touch-sensitive capacitive-type user switch
  • Highly visible two-state RGB LED ring (7 selectable colors + OFF) indicates mute status
  • Low-profile element provides uniform cardioid polar pattern with 120° acceptance angle
  • Mounts unobtrusively in tabletops and panels
  • Self-contained power module with XLRM-type output connector
  • Rugged all-metal case with a two-layer perforated grille
  • Rubber Isolators provide mechanical dampening of mounting-surface vibration
  • Requires 11V to 52V DC phantom power
  • UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)

    This phantom-powered cardioid condenser boundary microphone features a 5-pin XLR output connector with a touch-sensitive capacitive-type user switch for enhanced control in conference and boardroom installations. Not only can the switch be configured to toggle between mute and live auido, but, with the microphone’s external contact closure, it can also be set up to trigger an external device,u sch as a camera or the room’s lighting.

    Designed for clear, highly intelligible conferencing, recording, monitoring and other demanding sound pickup applications, the ES947C/FM5 mounts unobtrusively in tabletops or panels, but includes a highly visible two-state RGB LED ring (7 selectable colors + OFF) to indicate mute status.

    The microphone’s cardioid polar pattern provides 120° coverage. A rugged all-metal case with a two-layer steel mesh grille protects the microphone element, while our UniGuard® RFI-shielding technology provides outstanding rejection of radio frequency interference (RFI).

    The ES947C/FM5 is equipped with a self-contained power module, eliminating the need for an external one, and comes with a pair of rubber isolators for optional mechanical isolation from the mounting surface.
