If you have an external source linked to your BluOS Player via an Optical or Analog Input, you can utilize the connected Player to play this source. To have this external source play through multiple Players across your BluOS network, you should create a group comprising these Players, with the Player connected to the external source serving as the primary Player within this group.
For example, if you have a Bluesound POWERNODE linked to your TV via an optical connection and require to stream the TV's audio to your Bluesound PULSE M in the kitchen, designate the POWERNODE as the primary Player and form a group with other Players.
