The A-H484 multisource hub allows you to play up to four audio sources through your A-BUS system. You can select any source independently in each zone at the keypad or with an A-LRC1 remote control. Each zone may have one or two rooms with A-KP2 Amplified Keypads.
To control the sources, you can use either the A-LRC1 or the source manufacturer’s remote. The A-H484 passes source commands from each zone to the source selected in that zone. It also provides a common IR output to pass source commands from all zones.
The A-H484 provides four zones. Multiple A-H484 hubs can be linked together to accommodate larger systems.
Simple and elegant, the A-K3 Amplified Keypad provides easy control of your music. Turn it on or off, select from up to six sources, or adjust the volume with just a touch—or use a remote control if you prefer.
As inconspicuous as a light switch, the A-K3 complements your décor. Its built-in amplifier powers your room speakers directly, or you can use its line outputs to feed an external amplifier or powered subwoofer.
The A-K3 works with any A-BUS hub or controller, as well as with A-BUS-ready receivers and A-BUS subzones on multiroom controllers.
Local Source Input
The A-LC3 Local Source Input allows you to connect a computer, CD player, or other audio source to the room speakers in an A-BUS zone. It automatically selects the connected source when it senses an audio signal. You can then use the room keypad or volume control to adjust the speaker volume while playing the local source, just as you would while listening to a source through the main A-BUS system. When used with a Russound A-K5L keypad, it will turn on the zone’s keypad.
Designed to install in a single-gang wall box, the A-LC3 connects with CAT-5 cable between the A-BUS system hub (or A-BUS-ready receiver) and an A-BUS Amplified Keypad or Amplified Volume Control.
The 845.1 IR Micro-Emitter transfers infrared commands to a single audio-video component or other device. Its head attaches to the component’s IR sensor with an adhesive pad. The emitter’s cable plugs into an emitter jack on a multiroom controller or hub, or an IR connecting block such as the Russound 857 or IRB-6.

Questions and Answers:
By Alfred B. Klamm from Germany on July 25, 2012
I'm interessted in the a-bus set you offer. Did yout send it to customers in Germany? Are there problems with german audio or elektric standards? What's the price for shipping? Are there customs duty to pay?
Thank's for helping!
By Customer Service - Q&A on July 25, 2012
The most economical way to ship to Germany is USPS priority international. Put in your postal code, change the country to Germany, and select USPS priority international for your shipping method and press Apply for shipping quote on the site.

I have installed Russound's A-BUS system in my home. Wnen I turned off the source music (receiver, Ipod, etc), why all the wall pads (the amplifers) and hubs could not be turned off, but still on? My understanding that A-BUS should turn off all the wall pads and hub when the music source turned off.
By Customer Service - Q&A on November 29, 2011
The Owner’s Manual and information does not seem to answer your question. I see that the system features auto turn on when you turn the source on. Then the wall plate/amplifiers become active. I am assuming you need to turn off the system either at the key pad or with the remote control. I would suggest you direct the same question to the following:
email@example.com. They are the company that first introduced A-Bus to the US (from Australia).

What is a good ceiling speaker for this system? I know the system has low wattage, so what kind of speaker would be the best choice to produce good quality sound despite the power limitations of A-BUS?
By Customer Service - Q&A on February 24, 2012
I would not sell the A-BUS short regarding power. The whole concept was that the amplification would be located in the Volume controller in the room closer to the speakers. The ideal setup is to have a dedicated amplifier per room. Shorter Speaker level runs produce less loss. We would recommend the OSD PRO series in-ceiling speakers. They have the broadest selection and are the most efficent (91dB) take less power to drive them.
