Troubleshooting Guide Ifthe remote ABUS modules do not operate at all: - Verify all connections between the remote modules and the ABH 4 - Check the RJ45 connection between the ABH 4 and the host receiver (ABUS/ READY systems) -Check the AC power connection at both the ABH 4s Power jack and on the Power Supply If the remote modules status LED is lit but there is no sound: -Make certain that an active source has been selected on the host receiver -Check the RJ45 connection between the ABH 4 and the host receiver (ABUS/ READY systems) -Check the audio connections between the ABH 4 and the host receiver (nonABUS/ READY systems) For additional troubleshooting information and updated operational and installa tion hints, please visit the Product Support section of the Harman Kardon Web site at www.harmankardon.com. Specifications ABH 4 Dimensions (D x W x H): 35/16" x 73/16" x 13/16" (83mm x 184mm x 30mm) Weight: 0.9 lb (410g) Power Supply Dimensions (D x W x H): 213/16" x 515/16" x 17/16" (70mm x 151mm x 36mm) Weight: 1 lb (450g)Power Supply Input: 108 – 264 VAC, 115 watts Power Supply Output: 24volt, 4amp supply included Status Power: 12 volts, 200ma Wiring protocol for ABUS connections: TIA wiring specification for TIA 568A Operation When the installation is complete and all connections have been made to the ABH 4 and receiver, processor or preamplifier, and the ABUS 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. After checking the connections, plug the AC power cord from the ABH 4s Power Supply into a nonswitched AC outlet and turn on the host receiver, processor or preamplifier. Operation of the ABH 4 is seamless, as the remote ABUS modules will communicate directly with the host source. When the ABH 4 is used with an ABUS/ READY receiver, the ABUS modules in the remote room operate as if they were connected directly to the host receiver.Nofurther controls are needed. Follow the instructions included with the ABUS modules for operation information. When the ABH 4 is used in the standalone mode with a source that is not ABUS/ READY , the method of operation varies depending on the specifics of the installation: -When a 12volt adaptor is not connected to the ABH 4s Status Input ¡ , the system is able to pass through IR commands from the remote modules to turn on the host receiver, processor or preamplifier, but there is no power to a remote modules internal amplifier until an audio signal is sensed at the ABH 4s Audio Inputs £ . -When a 12volt adaptor is connected to the ABH 4s Status Input ¡ ,the system is ready for full operation at all times, including passthrough of IR commands from remote ABUS modules as well as power to the remote modules internal amplifiers. The three LED indicators on the ABH 4 signify the following operational modes: Status Indicator å lights when the system is activated either by con nection to an ABUS/ READY receiver that is turned on, when a signal is sensed at the Audio Inputs £ or when a 12volt power source is connected to the Status Inputs ¡ . This light indicates that the remote modules are active and ready to accept and transmit commands. -The Power Indicator ∫ lights when the AC Power Supply is connected to the ABH 4 and/or when a connection is made between the ABH 4 and an ABUS/ READY receiver.This light indicates that the system is powered on and is operational. - The IR Indicator ç flashes whenever an IR command is transmitted through the system. Optional Step Five: Status Power Connection Ifyour system requires that the remote ABUS models are active and able to receive commands when the host receiver, processor or preamplifier is not turned on, connect an optional power supply to the Status Input ¡ .The power supply is the small type typically used to power portable electronics products and should provide a nominal 12 volts DC at 200 mA, using a standard 2.1 plug with Center Positive. Optional Step Six: Connect IR Emitters Ifyou are not using direct IR control connections to IR In jacks on products by Harman Kardon and wish to control a receiver, processor or preamp, or a source product such as a CD or DVD player, connect optional IR emitters to the IR Emitter Jacks ¶ and then place them over the IR sensor on the front panel of the unit to be controlled in accordance with the emitter manufacturersinstructions. Optional Step Seven: Remote IR Sensor Connection If the source and control equipment is behind cabinet doors or dark glass and you wish to have an optional IR sensor in the main listening room control those products, connect that sensor (not included) to the Local IR Input Terminals § .To make the installation easier, the black connector block may be removed by grasping the top and bottom of the block and pulling it out toward you. Reinstall it after the connections are made by simply pushing it back into the socket. When using an optional IR receiver (not supplied) the connections are as follows: ABH 4 Local IR Connection Point Sensor Connection Point V+ +12VSIG IR OUT GND GND NOTE: The STAT connection is not used in standard installations. If you are not familiar with the use of external IR sensors in systems integration applications,we strongly recommend that a trained custom installer perform the installation. Connections to a NonABUS/ READY Product The ABH 4 may also be used to bring the benefits of ABUS technology to audio systems that are not ABUS/ 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. Although this installation is rela tively simple, you may wish to have it completed by a trained installer who is familiar with ABUS and audio/video systems integration. Step One: Connect an Audio Source Connect the audio outputs of the source that will be used to feed the ABUS modules by using a standard audio interconnect cable (not included) connecting the Audio Inputs £ on the ABH 4 to the audio outputs of the source device. The source may be the tape outputs of a stereo preamplifier or receiver, the tape outputs or multiroom outputs of an audio/video receiver or surround processor, or it may be a direct connection to a single source such as a CD player or tuner. Step Two: Connect the ABUS Modules Connect the RJ45 jacks on the Cat. 5 cabling that runs to the remote room modules to the ABUS Outputs - on the ABH 4. Make certain that the con nector is wired in accordance with the standard TIA 568A colorcoding. Connect the ABUS modules in the remote rooms to the cable in accordance with the instructions for the module. Step Three: Connect the AC Power Supply Connect the AC Power Supply furnished with the ABH 4 to the Power Input ™ . Plug the AC power cord into the socket on the Power Supply. Do not connect the power cord to an AC outlet at this time. Optional Step Four: Multiple ABH 4 Connections If you are using more than one ABH 4 in a system, connect the Expansion Out Jack ∞ to the Expansion In Jack ¢ on another ABH 4, using the RJ45 jumper cable supplied with the second ABH 4. Then, follow steps two and three as shown above. NOTE: The following steps provide additional options that extend the flexibility of your ABUS system. If you are not familiar with audio/video systems installations, you may wish to have them completed by a properly trained installer.
