Add-on A-BUS expansion hub for relaying sound to eight rooms.

Four-room/eight-room A-BUS expansion hub


Using any A-BUS®-compatible Harman Kardon® products as a central source, the ABH 4000 expansion hub provides flexible sound distribution (via AB 1 amplified in-wall modules) across four separate entertainment zones to as many as eight rooms in your house or apartment. And if you need to add A-BUS connectivity to a receiver, pre-amplifier or surround processor that is not A-BUS/ready™, the hub’s onboard audio inputs will distribute sound from “Tape” or “Multiroom” ports. To provide even more extensive sound coverage, you can cascade multiple units together using standard Cat. 5/5e cables.
