■Connection to a video or web conference system
This unit can be connected to a video or web conference system for use as a microphone/speaker of the system.
Replacing the audio input/output of the system with this unit achieves a smoother conference for both talkers and
listeners.
■Audio conference that is "easy to talk" and "easy to hear"
This unit employs arrayed microphones with high voice capturing capability and speakers with high voice reproduction
capability. It also incorporates a high-performance adaptive echo canceller to eliminate interruptions of sound or drop in
the voice level when multiple talkers speak simultaneously. These features make your audio conference "easy to talk" and
"easy to hear".
