Harman Kardon ABH4 Four Room A-BUS Expansion Hub with RJ-45 Connection Jumper Cable

With the Harman/Kardon ABH 4 Expansion Hub no room in the house need be without music, no matter which AVR is in use. For existing systems linked to A-BUS Ready products, the ABH 4 allows you to power up to four rooms, or even more with additional ABH 4 hubs.

For systems without an A-BUS Ready jack, the ABH 4's onboard audio inputs add the simplicity of A-BUS technology to any multichannel or stereo receiver with a "Tape" or "Multiroom" output; you can even use it directly with a CD or DVD player or outboard tuner to bring music to any room.
