Each Nexia device comes pre-configured from the factory with a default system design. The factory default configuration for a NEXIA VC is a 'videoconference system' with 8 automixer AEC mic inputs, 2 program line inputs, and a codec input feeding a matrix to 4 outputs and a codec output (see design layout below). This "VC Default Configuration.NEX" file can be found under Sample Files on the NEXIA software CD. If you wish to load your own custom designed configuration you will need to reset/initialize the unit(s) first.
