Multi and unicasts

  • Be aware that multicast’s are always sent, even when there is no “subscriber”. So the network components can be overloaded even if nowhere sound play’s
  • Unicast’s are only sent  if there is a valid routing and the receiving Dante unit is alive. Maximum 2 concurrent Dante Unicast can be sent per unit/stream. A third assigned unit will play nothing until one of the two unicast’s are free
