AVM500-ES is an EtherSound Network Matrix in a 19” 1U rack box for linking and routing up to 5 EtherSound Networks together. AVM500-ES Integrates a full matrix router of 320 x 320 audio channels. AVM500-ES enhances EtherSound standard daisy chain connection and enables to build star architectures of mixed bidirectional EtherSound or ES100 devices or sub-network. Multi AVM500-ES can be ringed together using their twin IN and OUT A Ports to create a redundant ring of EtherSound Networks. AVM500-ES has an auxiliary power supply input to build safety systems.
