4 Zone/Single Source Surface Mount Hub



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.

With a receiver or preamplifier connected to the A-H4, you can select any of your music sources to enjoy throughout the house. Or you can connect just a single audio source, such as a computer or a CD changer.

For added convenience, an optional Status feature indicates on your keypads when the receiver is on and turns all your keypads off when it’s turned off.

The A-H4 is designed for surface mounting, such as on a shelf or in a rack with your source equipment.
