Each Nexia device comes pre-configured from the factory with a default system design. The factory default configuration for a NEXIA TC is a 'teleconference system' with 8 automixer AEC mic inputs, 2 program line inputs, and a telephone input feeding a matrix to 4 outputs and a telephone output (see design layout below). This "TC 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.
