Audio-Technica has announced four new condenser boundary microphones – the ES945O/FM3 omnidirectional, ES947C/FM3 cardioid, ES945O/FM5 omnidirectional and ES947C/FM5 cardioid condenser boundary microphone.

These mics feature a capacitive-type user switch for audio muting, making them especially suited to conferencing applications. The FM3 models replace the existing ES945/LED and ES947/LED and feature local muting, while the FM5 models are new and offer an advanced feature set offering remote muting and control.

Audio-Technica boundary mic familyThe omni ES945O/FM3 and cardioid ES947C/FM3 have a 3-pin XLR output connector and mount unobtrusively in tabletops or panels, but include a highly visible two-state RGB LED ring (seven selectable colours and ‘off’) to indicate mute status. The mics’ polar patterns provide 360° (ES945O/FM3) and 120° (ES947C/FM3) coverage, respectively.

A rugged all-metal case with a two-layer steel mesh grille protects the microphone element, while proprietary UniGuard RFI-shielding technology provides outstanding rejection of radio frequency interference (RFI). Both mics are equipped with a self-contained power module, eliminating the need for an external one, and come with a pair of rubber isolators for mechanical isolation from the mounting surface.

The omnidirectional ES945O/FM5 and cardioid ES947C/FM5 have a similar feature set to the FM3 models, but offer remote muting and control, as well as a 5-pin XLR output connector. Additionally, with the FM5 models, not only can the switch be configured for remote muting and/or external contact closure, but it can also be set up to trigger an external device, such as a camera or the room’s lighting.

Key features:

  • Designed for surface-mount applications.
  • Capacitive touchswitch (local muting for FM3, remote muting for FM5).
  • Logic I/O permits remote muting and control (FM5 only).
  • Two-state RGB LED ring indicating mute status.
  • Self-contained power module with 3-pin (FM3) or 5-pin (FM5) XLR output.
  • All-metal case with two-layer steel mesh grille.
  • Rubber Isolators provide mechanical dampening of mounting-surface vibration.
  • 11V-52V DC phantom power
  • UniGuard RFI-shielding technology.
  • RoHS compliant.

The ES945O/FM3 and ES947C/FM3 boundary microphones will be available in Q2 2021 with US MSRP pricing of US$263 and US$263 respectively. The new ES945O/FM5 and ES947C/FM5 are now available with US MSRP pricing of US$279 and US$279 respectively.
