Hi. I have a setup where I have a audio matrix switch in the basement AV closet and would like to place the amplifiers for the distributed audio closer to where the speakers will be. Around 20 zones are in the same building on different floors, and 6 zones are in another building next door. They need to play music from the same source in sync. Is there some way I could transport the output from the matrix switch to the amplifiers over ethernet or any other similar solution? Thanks.
