    On iVAM1-1, the AoIP source can be selected through the Source Select option. The iVAM1-1 is set up at the Wohler factory to be used as a slave rather than a master within the Dante network. Other devices or software, such as a Dante Controller, are expected to be responsible for most device configurations and all audio routing.
