Russound A-H4D

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.
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, a Status feature indicates on your keypads when the receiver is on and turns all your keypads off when it's turned off.
Designed with an attractive Decora® style, the A-H4D installs in a double-gang wall box.
