A-BUS multi-room audio is unique in distributing audio to the target room,
amplifying it at the keypad, then passing it to the loudspeaker. This means that
you can use your existing stereo source, eg normal stack system, micro or mini hi-fi
without any additional amplifying equipment in the source room.
Single source
In addition to your main listening room, which remains unaffected,
A-BUS delivers music to up to another 4 rooms using the standard single source kit, but this can be expanded considerably
Wiring installation is straightforward using Cat5e cable from the surface mount hub to the keypads, then
speaker cable to the loudspeakers.
Volume control is by the amplified keypads. These are available as either US style - see above photo on left, or
as an EU/UK style with flat plates, shown above centre and right photos. The system has an IR receiver built into each of the
keypads that can receive and transmit signals back to the
stereo components via 4 built-in IR emitter outlets for full control. Single source
kits include hub, keypads, power supply, remote control, IR emitter and punch down tool. 4 source kits also include
a local source input plate, extra IR emitters and the learning remote control.
The standard US style keypads require
US style single backboxes.)
The system has a power rating of 8 Watts, which is ideal for general
listening throughout your house. Ceiling speakers with matched power ratings are
supplied separately and can be chosen from our in-ceiling speakers range.

If you want to have a tidy termination of the Cat 5e cable from the keypads near the central hub, you can use the HNS RJ45 data outlets
either with or without the HomeCabling patch panel, and connect to the hub by a patch lead. If you use this system
you must use our special T568A to T568B patch leads, because the Russound unit uses the American RJ45 colour coding but
the HNS system uses the UK T568B colour coding. Price for the 1.5 metre patch lead is shown below.
Multi-source
ABUS is also available as MULTI-SOURCE with the 4 source surface mount hub, which allows you
to choose independently from 4 sources in any of the 4 rooms. In fact each zone can drive two keypads so
you can easily have music to 8 rooms! (NB: if you have more than 4 keypads working off a single hub,
then to power these you need an extra power supply). You can add this to your existing A-BUS system,
or buy it as part of a complete kit (AM341UK, see below),
including the 4 souce 4 zone hub, 4 AKP2.2 keypads, a learning remote,
APS power supply, and a single A-LC local source input.
System expansion
The range of surface mount hubs allow you to add an extra 2 or 4 zones to your
existing system, or have a complete 2 zone system.
The hubs
require an A-BUS APS power source, which drives 4 keypads. For 5 to 8 keypads you need two
power supply units. For 9 or more keypads you need extra hubs and more power units
You can combine the Russound ABUS keypad with Lutron Grafik Eye light control wall station keypads in a US style double gang
faceplate as shown in the photo. These faceplates can be white plastic (Decora type or screwless type as shown) or stainless steel
or brass Decora type, see here.
Local source input
You can also add a local (room) input option with the ALC3 wall mount plate. This is ideal where your youngsters want
to listen to their own mini system or personal CD player through the room speakers. It is also ideal if you want
to use the stereo room speakers whilst watching TV. The ALC does not require power.
More power
For rooms
where you need more music volume, Russound
offer their
R235LS in-line amplifier, generating 35 Watts per
single zone (2 channel). This links to the AKP keypad and is controlled from it, using the keypad amp just as a pre-amp.
