There is an amazing amount of technology built into the Quattro yet it isabout half the size of competitive units that do less.

Unlike other products that utilize their multiple microphones by gating one of them at any time based on the signal level, the Quattro uses all of its four microphones concurrently with "beamforming" technology.

uses its microphones to develop a beam directed at the person or persons speaking. Our "beam" is not just looking for the loudest signal it is actually checking for noise, reverberation, and stray non-voice sounds like key strokes and door slams, and then works to eliminate them. If more than one person is speaking at the same time the Quattro will effectively create several 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 audio onto 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 for a 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. Most other products either compromise the full duplex performance, limit the loudspeaker sound level, or design the microphone as far as possible from thespeaker. Our echo cancellers work in the confinedsmall space that the Quattro is packaged in and with a sound level which is about four times louder than any other product you have experienced before.
