ES947 Cardioid Condenser Boundary Microphone

The new Engineered Sound. Contractor-exclusive innovations for every acoustical challenge. And safe haven from RFI.

This low-profile cardioid condenser boundary microphone is recommended for unobtrusive table-, ceiling-, or panel-mount applications in high-quality sound reinforcement, professional recording and teleconferencing. Designed for permanent installation, the microphone is equipped with a self-contained power module with an XLRM-type output connector, eliminating the need for an external power module. Protected by a rugged all-metal case with a two-layer steel mesh grille, the microphone has a cardioid pattern for enhanced gain before feedback and improved signal-to-noise ratio. It is available in two colors: black (ES947) and white (ES947W).
  • Designed for surface-mount applications such as high-quality sound reinforcement, professional recording and teleconferencing

  • Low-profile element provides uniform cardioid polar pattern with 120º acceptance angle

  • Mounts unobtrusively in table-tops, ceilings and wall panels

  • Self-contained power module with XLRM-type output connector

  • Rugged all-metal case with a two-layer steel mesh grille

  • 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)

  • Available in two colors: black (ES947) and white (ES947W)
  • RoHS compliant—free from all substances specified in the EU directive on hazardous substances

Answer: 
Thank you for your inquiry. It can be mounted in the ceiling. This microphone is directional, so place it in such a way that the speaker and other sounds are in the off axis of the microphone to better reject these sounds.
