Multi-zone or multi-room Audio is simply your ‘media’ available in areas in and around your home - where you want it.
It could be as simple as a Home Theatre area with a second zone outside in the BBQ area. Or a sophisticated multi-room audio and/or
Ultra High Definition video system.
All can elegantly controlled by simple or more sophisticated and elegant ‘interfaces’, whether it be a volume control, keypad, remote or your smartphone in and around your home.
