SoundStation Premier EX delivers the world's best full-duplex audio quality for any conferencing situation - it's the closest thing to handset audio quality. Polycom's full-duplex technology allows you to talk and listen at the same time, just as naturally as if you were in the same room - no clipping and no distortion like you get with ordinary speakerphones. The Polycom SoundStation Premier Satellite system adds a second powerful speaker to the one built into Polycom SoundStation Premier, to fill almost any size room with crystal clear sound. You can also get up to seven directional microphones for broader coverage. Featuring a modular, portable design, Polycom SoundStation Premier Satellite is easy to install and customize for the largest conference or boardrooms. Other features include convenient console connectivity for a standard analog phone line, an RCA jack that allows you to record calls, and an interface to connect a telephone handset for privacy.
