Details: The Polycom SoundStation VTX 1000 with Acoustic Clarity Technology is truly a leap in voice conferencing technology. It's the world's first conference phone that automatically adapts to each meeting environment, providing high fidelity voice clarity for all participants. With the SoundStation VTX 1000, conference call participants can speak at a normal, natural conversation level and be heard clearly from up to 20-feet away from the microphone - even in large conference rooms. And, when two SoundStation VTX 1000 conference phones connect on opposite ends of a call, the phones automatically connect in VTX Wideband mode, resulting in extraordinary fidelity. SoundStation VTX 1000 is the voice platform for the future. No wonder Polycom is the #1 choice in conference phones, worldwide.
