ABH 4 4-Room A-BUS® Expansion Hub ® ® Power for the Digital Revolution. Power for the Digital Revolution.
Introduction Additional Installation Information Thank you for choosing Harman Kardon®! The ABH 4 Expansion Hub that you have purchased will enable you to extend the capabilities of an A-BUS®based multiroom system to four or more rooms, with a Harman Kardon A-BUS/READY receiver as the control point.
• A-BUS Outputs: These jacks are the communications link between the remote A-BUS modules and the ABH 4, carrying audio signals and power to the A-BUS modules, and IR commands from the A-BUS modules to the ABH 4 and products connected to it. Connect a cable from each remote A-BUS module to these outputs using standard RJ-45 connectors with cabling wired in compliance with the TIA 568A standard.
• Drill a pilot hole and install an anchor or retaining socket sufficient to accommodate a #10 pan-head Phillips-type wood screw that is at least 1 inch long at each side, under the circular part of the tracing. If you have any questions or doubt about the ability of the wall surface to properly support the weight of the ABH 4, consult a properly trained installer before proceeding.
When using an A-BUS/READY product, use the supplied RJ-45 jumper cable to connect the A-BUS jack on the receiver to the “Expansion In” jack on the ABH 4.

Connections to a Non-A-BUS/READY Product Optional Step Five: Status Power Connection The ABH 4 may also be used to bring the benefits of A-BUS technology to audio systems that are not A-BUS/READY. To do this, a few additional steps are required to connect an audio feed and to install any required infrared emitters that are used to control the source equipment.
When using the ABH 4 with non-A-BUS/READY receivers, connect either the Multiroom outputs (if available) or the Tape outputs to the Audio Input ¢ jacks on the ABH 4. Optional 12V power supply Connect to either the Multiroom or the Tape outputs, but not both.
Operation Specifications When the installation is complete and all connections have been made to the ABH 4 and receiver, processor or preamplifier, and the A-BUS modules have been properly installed in the remote rooms, operation of the ABH 4 is simple. There are no user controls on the ABH 4. ABH 4 Dimensions (D x W x H): 3-5/16" x 7-3/16" x 1-3/16" (83mm x 184mm x 30mm) Weight: 0.
