What are the implications of using the multicast signal?

Multicast is very efficient for one-to-many signal distribution, such as front-of-house to many amplifiers in a stadium. With multicast, a single stream of network packets is transmitted by the source and the packets are replicated by the network switches as they travel through the network. In networks that do not support controlled distribution of multicast (a common case), the multicast packets carrying the audio channels will flood throughout the network. Dante devices support IGMP snooping which avoids flooding and delivers the multicast audio packets only to devices that have requested those channels. For point-to-point connections between two Dante devices, multicast is not useful and is not recommended.
