If more than one person is speaking atthe same time the Quattro will effectively createseveral beams and mix them together in a sophisticated way based on each beam"s Signal (voice) to Noise Ratio. This is being re-evaluated thousands of times per second to ensure the best and cleanest possible signal is being sent to the far end.- We also provide high definition, wide band audioonto networks that accept it- Typical phone lines have frequency responses of approximately 300 to 3500Hz which lack dynamic range and sound flat. The Quattro can provide up to 20 to 20,000Hz fora full sounding conference including all of the voice inflections and nuances that provide for a much more natural and productive meeting experience.- Features echo cancellers that provide true full-duplex communication.
