A-BUS Local Source Input Module (ABUS-LS1RJ): The LIM provides “local”
input capability for sources such as TV sound, MP3 player, computer sound cards,
etc. located in the zone. The LIM automatically switches to the local input when a local
source is detected. 30-seconds after the local source ceases, the LIM automatically
reverts to the main input source. The LIM is easy to install. Note- Care should be taken
during pre-wire to run the category 5 cable from the hub to the power module via the
LIM installation point if this facility is to be made available. This is often a forgotten
requirement, e.g. In the case of local TV, the category 5 cable should be run past the
room’s aerial point.

A-BUS COMPATIBILITY:
by
This product complies with the A-BUS format. The A-BUS format has been adopted by
other manufacturers who make variety of products that can give your system added
flexibility. When looking to expand and/or upgrade your home entertainment system,
be sure to look for products that carry the A-BUS trademark.

Welcome to A-BUS Multi-Room Audio. When combined with our source equipment
(receiver, CD player, etc.) and speakers., A-BUS creates a versatile whole-house au-
dio system that will fill your home with high-quality music for years to come.
A-BUS SYSTEM OVERVIEW:
A-BUS Hub (ABUS-HUB1X2, ABUS-HUB1X4): The A-BUS hub is the core of the
system, distributing audio signal, system power and status indication to A-BUS power
modules installed in rooms throughout the home and sends IR commands from the
power modules back to the source components. It is usually located near the main
sound system (Amplifier/Receiver, CD, DVD, Tape, Cable, etc.). They typically have
two or more zone outputs with expansions ports (IN/OUT) so multiple hubs can be
connected to tailor the system to individual requirements.

●OUT: Connects to additional hubs to add more zones or rooms. (Each hub requires
its own power supply)
●IN: connects to the direct input of an A-BUS/READY amplifier or connects to an A-
BUS input selector.

●Local infrared input (xantech™ compatible) to relay IR commands if the main system
amplifier is concealed (single zone amplifiers only).
PRODUCT INSTALLATION NOTES:
●All A-BUS RJ-45 connectors are wires to the 568A standard.
●The colour code order of punchdown connectors may vary.
●Standard CAT5 patch leads may be used.
A-BUS Volume Control Power Modules (ABUS-VC2RJ): A-BUS volume control
power modules are stereo amplifiers with level control that power a pair of speakers
in each room. Only one category 5 cable is required between the hub and the power
module. Speaker cable is run from the power module to the speakers except when the
A-BUS power module is located on the speaker itself. Standard rotary A-BUS power
modules do not include infrared repeating. IR-equipped modules relay 38KHz and 56
KHz codes to the source components for input track/channel selection, etc. They also
include infrared talkback and status indication. An LED indicator indicates when the
A-BUS system is on (See Power/Status below) and it flashes signifying an infrared
command has been received. The volume level on touch-button A-BUS modules can
also be operated by the ARC-40 remote control handset (supplied with ABUS-VC2RJ).
The IR repeater system is always active regardless of system status.
●The infrared system will relay 38kHz and 56 kHz commands.
IMPORTANT: Substitute power supplies are not recommended.
Pre-Wiring: All cabling between the A-BUS/READY amplifier/interface module, dis-
tribution hubs and power modules should be category 5 cable or better. The recom-
mended maximum cable run is 100 feet (30m). Speaker wire should be run from the
power module point to the speaker points; however, it is recommended that the cat-
egory 5 by extended to the speaker points as well to allow for the installation of an A-
BUS/direct speaker system which has the power module incorporated in the speaker.
A-BUS power modules will accept up to 14 gauge cable. It is recommended to extend
the category 5 cable past the power modules to the speaker points for future require-
ments. It is recommended that all category 5 cables at the hub end be terminated
with wall mounted RJ-45 sockets with standard (568A) patch leads between the wall
socket and the hub.
Before installing the category 5 cables check for Local Input Module requirements.
Eg. in the case of a local TV, the CAT5 cable should be run past the room’s antenna
connection point. A 12” taped loop of cable for access is recommended. The same
could be applied to a point in a child’s room next to a desk where a computer or MP3
player may be located.
Audio, IR Data and Status Connections: A-BUS/READY amplifiers are equipped
with an RJ-45 A-BUS output socket enabling direct connection to either a single A-BUS
Volume Control power module for one extra zone or to an A-BUS hub for multiple-
zones. The A-BUS/READY outlet supplies audio, status and infrared data connection.
Some A-BUS/READY amplifiers can power one power module independently while
others require a separate power supply. The A-BUS/READY jack may also be con-
nected to the Expansion Input of an A-BUS hub to enable multiple zones.
IMPORTANT: When purchasing a new amplifier or home theater receiver look for the
A-BUS/READY logo on the front. That means a simple RJ-45 connection on the back
immediately connects you to the whole-house system, as long as the house is wired
for A-BUS.
IMPORTANT: These instructions contain directions for installers of A-BUS systems.
The manufacturer or its agents shall not be liable to any person or entity for loss or
damage, including consequential loss or damage, arising out of any error or fault in the
installation of the A-BUS system or any of its components parts.
Power/Status: There are several ways to activate an A-BUS system. When not in
operation the A-BUS system is in standby mode. It is activated by:
●Automatic Signal Sensing (Default): The Hub automatically detects when audio sig-
nal is present and activates the A-BUS system. 30 seconds after the audio signal ends
the system returns to standby.
●Main System Sensing (Preferred): A-BUS also activates automatically when the main
sound system is switched on (including source components). A 12-volt 100-300 amp
power pack should be plugged between the main amplifier’s switched power outlet and
the hub’s Status input.
●A-BUS/READY: The hub can be directly connected to an A-BUS/READY amplifier
via the Expansion Input port. The A-BUS system automatically powers up when the
A-BUS/READY amplifier is switched on. This may be done via remote control from any
room. Note: The hub power supply is still required.
IMPORTANT INSTALLATION GUIDELINES:
Before installation, review the manuals included with each component in your system.
If you are unsure of any of the installation procedures, it is recommended that you
contact your dealer or a professional electronics installer. During installation, do not
connect power to the hub. Before powering up the system, make sure all volume levels
are on minimum level. Note- before installing the power modules into the walls be sure
to adjust the trim pots after all modules have been connected. The power modules
should be installed into standard UL/CSA approved electrical J-Boxes.
