The innovative A-BUS system makes it incredibly easy to bring Harman Kardon sound to a remote room. Connected via a single cable, the AB 1 powers most in-wall speakers from its internal amplifier, with volume controlled by the up/down toggle or a Harman Kardon remote. A built-in IR sensor completes the package, making it simpler than ever to enjoy music throughout the house.

REVIEWS:
1) Very nicely done: Looks great, sounds great and sends commands great, every new house being built today should be wired for AB1. Just add the ABH4 and a A-Bus ready receiver and you will simply be amazed at what all you can do, oh and did I say how good it sounds, it drives my Polk Audio ceiling speakers just fine.
