The central component of any A-BUS system
What do you need to start an A-BUS system? First, select a hub, in either single-source or a multi-source version.
The A-H484 multisource hub allows you to play up to four audio sources through your A-BUS system. You can select any source independently in each zone at the keypad or with an A-LRC1 remote control. Each zone may have one or two rooms with A-K4 Amplified Keypads.
The A-H4 hub is the heart of a single-source A-BUS music system. It sends the output of your audio source to A-BUS Amplified Keypads or Amplified Volume Controls in up to four rooms. If you want music in more rooms, multiple A-H4 hubs can link together to provide more A-BUS zones.
As the heart of a single-source A-BUS system, the A-H4D hub sends music from your audio source to A-BUS Amplified Keypads or Amplified Volume Controls in up to four rooms. To provide music in more rooms, one or more A-H4Dx Expansion Hubs can be added to the A-H4D.
The A-H2 hub gives you two rooms of music from a single source. By connecting a receiver to the hub, you can use the receiver to select other sources. Or you can connect just a single audio source, such as a computer or a CD changer.
