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.The A-H2 supports A-BUS Amplified Keypads and Amplified Volume Controls. An optional Status feature indicates on your keypads when the source receiver is on and turns your keypads off when it's turned off.Ideal for adding a couple of rooms to a stereo system, the A-H2 can also link to an A-H4 hub to add zones to an A-BUS system. The A-H2 is designed for surface mounting, such as on a shelf or in a rack with your source equipment.
