A-BUS Installation Instructions

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.

●Audio input from the main ampliﬁer’s tape output or second zone output.

●4 Infrared (IR) outputs to remote controllable source components and the main ampli- ﬁer (to allow for input selection). Dual emitters may be used.

●Power supply for system power (supplied). (Should not to be connected to the ampli- ﬁers switched output.)

●Status optional (see below)

●Zone outputs to go to A-BUS volume control power modules. ●Expansion ports- to add additional zones. (A-BUS - HUB1X4)

●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).

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-buttonA-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.

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.

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.

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:

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.

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.

●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.

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.

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.
