User manual BIAMP 1200-2400

[. . . ] Intended for a variety of videoconferencing applications, Nexia VC uses Biamp's proprietary SonaTM AEC algorithm for more natural sound and full-duplex transmission of speech. [. . . ] The internal system design is completely user definable via PC software, and can be controlled via daVinciTM software screens, RS-232 control systems, and a variety of optional remote controls. Multi-unit Nexia systems can be created utilizing Ethernet and NexLink digital audio linking.
