Superior Audio Performance

  • Enhances video conferencing audio by placing high-quality microphone closer to participants
  • Distributed Echo Cancellation® effectively eliminates echo
  • Noise cancellation removes background noises from fans or HVAC systems
  • Wideband digital audio (50 Hz-7 kHz) enhances audio quality – matches video conferencing system bandwidth
  • Full-duplex sound enables participants to speak and listen at the same time without cutting in and out
  • First-mic priority eliminates hollow "tunnel" sound by activating only the microphone closest to the person speaking
  • Three microphones provide 360° audio pickup
  • Adaptive ambient mode prevents room noise from activating the microphone and adapts to changing noise levels
  • PA adaptive mode prevents loudspeaker audio from activating microphones to prevent feedback


  • Link an additional AccuMic VC for expanded coverage in larger rooms

Ease of Use & Control

  • Plug and play design – simply simply plug into any set-top video conferencing system and use
  • Mute microphone with the push of a button for private discussions during a conference call
