A multiroom system is anything from a music system with speakers in two rooms, to a system that allows you to watch any of your home entertainment sources in any room of your home - and beyond!
All from a single system hidden somewhere in your home.
At the office you access your work via a network, but you are not interested where the server is situated. In your home you access what you want to listen to, or watch, via a keypad in the wall or wireless Tablet in the same way.
Your CD player, Music storage hard drive, radio, hi-fi, video, satellite receiver etc. can be hidden away and distributed around your home without a wire in sight!
It is quite common to hide the main system in a less important room and then to access and control it, with no equipment visible, from any other room of your home. Including the main music room, with the same sound quality.
