The Fred W. Smith National Library for the Study of George Washington is a $45 million leading scholarly research facility for America’s first president. It is also filled with state-of-the-art technology that allows scholars-in-residence to videoconference with colleagues around the world. A SymNet Edge Dante networked audio DSP system delivers high-quality audio for the library’s six videoconferencing systems, as well as background audio and paging services. A dedicated SymNet Radius 12x8 DSP together with a custom Crestron computer control interface serve as the heart and brains of thelibrary’s recording studio.

Richard Derbyshire of Shen, Milsom & Wilke’s Washington, D.C., office designed the sound-reinforcement system, and IES Communications of Roanoke, Va., installed it. The sound reinforcement system and conferencing systems are located primarily in the conference wing of the library, where four conference rooms join the library’s lecture and conferencing space, The David M. Rubenstein Leadership Hall. Here, an 18ft. by 8ft. tiled screen provides videoconferencing. Four SymNet Edge frames are outfitted with 11 AEC cards, two two-line analog telephone interface cards, three analog input cards, and two analog output cards, all working in conjunction with two SymNet xIn12 and two SymNet xOut12 I/O expanders. The units are integrated using the Dante network audio protocol. All of the conferencing systems benefit from Symetrix’ advanced AEC hardware and DSP algorithms.

The audio and video recording studio is centered around a SymNet Radius 12x8 processor. Its open architecture allows custom recording and playback functionality that users control via a Crestron interface.
