Boundary Microphone Array


For high-quality sound in small conference spaces
Customizable directionality and coverage patterns

  • Hypercardioid and cardioid polar patterns can be formed 360 degrees around the microphone when used with the ATDM Series Digital SmartMixer® or compatible mixers
  • Multiple and simultaneous pickup patterns can be made to suit the seating positions of conference participants
  • Easily control the microphone from any position via three MUTE touch controls
  • Create an optimal audio environment for calls via touch controls for talking, muting, or localizing sound or changing the LED colors
  • Microphone ON/OFF status is indicated by seven ED colors that can be changed to match your branding or call environment
  • LED ring visible from any direction
  • Compatible with 20 to 52 V DC phantom power supplies
  • Proprietary shielding technology that protects the audio signals from radio frequency interference (RFI)
  • Low-profile, space-saving design: 88 mm diameter, 22 mm height
  • Fixable to the table with a dedicated 20 mm jig in a 30 mm diameter hole, or with general-purpose M3 screws
  • Includes cables (RJ45 breakout cables x 2) necessary for connecting to a mixer; two standard RJ45 cables are required separately for transporting audio and control signals

    The ES964 is a compact boundary microphone array that is simple to install and provides clear audio for multi-person conference environments. This microphone is designed for small-group online conferences, and for businesses that are considering installation or expansion of shared or permanent conference spaces. With its low-profile design, the microphone takes up minimal space on a tabletop, but still captures clear, natural sound for online calls.

    The ES964 has one omnidirectional capsule and two bidirectional capsules that can be matrixed into discrete directions and varying polar patterns. Designed to work with compatible mixers such as the ATDM-0604a or ATDM-1012, or with an open-architecture DSP, the microphone will provide 360-degree hypercardioid and cardioid polar patterns around the microphone for simultaneous pickup of all participants seated at the table.

    Intuitive touch controls enable users to mute audio or trigger a logic point from any of the three separate buttons on the mic. The buttons are accessible to meeting participants in multiple seating positions.

    The LED ring also provides immediate indication of the microphone’s ON/OFF/MUTE status and can be customized using seven different colors to match the design of your brand or office space.
