Russound 1-source, 4-zone A-BUS distribution hub

The A-H4 is a four-zone expansion hub for Russound A-BUS systems. With the A-H4 connected to a receiver or preamp, you can select any of your audio sources and send music to up to four rooms. You can also connect the A-H4 to an additional A-BUS hub, expanding your system to more locations around your home. The A-H4 works with Russound amplified volume controls and is compatible with Russound IR (infrared) emitters. It's designed for surface-mounting, such as on a shelf or in your equipment rack.
