With sensitive, high-performance speakers, SoundStation Premier delivers crisp, clear sound that's twice as loud as Polycom's SoundStation. It's also twice as quiet. The SoundStation Premier's automatic microphone switching technology means that only the microphone nearest the person talking is on, limiting extraneous noise from around the room. ??Like all Polycom voice conferencing solutions, the SoundStation Premier is designed with Polycom's breakthrough Acoustic Clarity Technology, which allows natural, two-way conversations.
