With full duplex for natural, simultaneous two-way conversation, the Sound Station2 EX will exceed your expectations. You can speak in a normal voice and be heard clearly up to ten feet away – making every call a more productive call. You’ll also enjoy many features, including a large backlit display that offers easily visible call information and telephone functions. Smart technology, such as Dynamic Noise Reduction (DNR), provides maximum microphone sensitivity, while reducing distracting room and background noise. And the SoundStation2 offers 360-degree microphone coverage with intelligent mixing so only the microphone closest to the speaker is on for crystal clear conferencing.
