When making the connections at each end of the cable, strip the outer insulation jacket about 1-1/2" to 2" from the end. The cable is constructed of four twisted pairs of wires, as indicated above. Flatten the wire ends to prepare them for insertion into the connector. Fully insert the wire into the connector, being certain to check the color codes of the pin assignments one last time. Carefully crimp the connector, making sure that each wire is securely fastened. Step Three: Connect the Category 5/5e cable to the AB 2. Once the wire is run to the remote location where the AB 2 will be installed, connect the Category 5/5e cable to the AB 2. Prior to making the connections, strip the outer jacket of the Cat. 5/5e cable 1-1/2" to 2" from the end, taking care not to nickthe inner conductors. Next, separate the four twisted pairs within the cable and then untwist the ends of each pair about 1/2." All terminations are made at the Input-Cable Connection Block . Connect the wires using standard 110 Insulation Displacement Connector (IDC) tools and procedures. DO NOT use screwdrivers to insert the wire into the IDC connection points. Make certain that there are no shorts between any of the individual wires, as this may cause damage to the AB 2. From left to right, the connections are made as indicated in the figure below. Step Four: Connect the speaker cable to the AB 2. Connect speaker wires to the AB 2 module using the color- coded chart on the Speaker Terminal Blockas a guide. Observe the positive (+) and negative (–) polarity indications, and avoid having the wire strands from one cable touch another. Loosen the retaining screws on the Speaker Terminal Block and insert the wire into the appropriate slots. Tighten the retaining screws to secure the wire. Step Five: Connecting the AB 2 to the A-BUS-equipped product. After making certain that the connections to the speaker cable and Cat. 5/5e cable have been made properly, plug the RJ-45 jack at the receiver end of the cable into the A-BUS jack on the back of the A-BUS-equipped product, and connect its IR output to the source devices IR input, daisychaining for more than one source. Next, turn on the receiver or other source and turn on the Multiroom system. As a confirmation that the system connections have been made, theStatus LEDwill light. When the AB 2 is turned on by pressing a source selector or using a remote control to issue an IR command, the red LED on the Power Off key will light, and a green LED will indicate the current source. Step Six: Adjust the output levels. This step sets the level adjustments for the AB 2. Once this process is complete, all further volume settings are made with the Volume Up/Down Buttonson the AB 2, the included remote, or any compatible third-party remote. With the Multiroom system activated and a source playing, press the Volume Up Buttonfor 20 seconds so that the AB 2s volume is set at its maximum. Next, adjust each of the Brown Brown and White Blue Blue and White Green Green and White Orange Orange and White Output-Level Trimsuntil the output begins to clip. At this point, back the trim control down in the opposite direction until the clipping stops. This is the correct level for your specific A-BUS- equipped product and the AB 2. Before proceeding further, lower the volume back to normal listening level. Step Seven (Optional): Switch keypads. You may switch keypads to better reflect the source devices connected to the ABH 4000 or other multizone hub. The Power Off/Mute, Skip Up/Down and Volume Up/Down keys remain the same, but the source names change from AVR to TN (tuner), CD to SAT, DVD to VID, and MP3 to The Bridge icon. Note, however, that The Bridge may only be connected to a Harman Kardon A-BUS-equipped product, and may only be selected as a playback source by pressing and holding the AVR Button on the AB 2 keypad. To switch keypad sets, remove the AB 2s white front panel by gently pressing the four clips that secure it to the back of the metal chassis. Be gentle so as not to inadvertently break off the clips. The entire keypad set may be removed and replaced, with the small holes on the sides of the keypad frame fitting over the corresponding pins on the back of the AB 2 front panel. When replacing the front panel, orient it so that the red lens fits over the red LED on the chassis. Step Eight: Install the AB 2. Place the AB 2 in the junction box or plaster ring, making sure that any loose wire is carefully secured inside the wall or box, and that there are no shorts between any of the connections. Using the supplied mounting screws, attach the AB 2 to the junction box or plaster ring through the Screw Slots. Attach a Decora-style wall plate (not included) through the AB 2s Screw Holes. Although any color Decora wall plate may be used with the AB 2, the AB 2 itself should not be painted. OperationWhen the AB 2 is properly connected to the system and the system is in standby mode (power is present but the A-BUS- equipped product is powered off), the Status LED will light to indicate that the system is ready to be turned on. When the AB 2 is turned on, the red LED under the Power Off key will light, and a green LED will light under the current sources key. Tap a source selector or use the ABR remote to turn on the AB 2 and begin play. Some source selectors offer additional commands, as indicated in the table below. NOTE: Some receiver models may require you to manually turn on their multiroom systembefore the AB 2 can be used. Consult the owners manual for the receiver for more information.Selector Tap/ABR Remote Press and Hold (AB 2 only) AVR First press turns on Selects The Bridge as system and plays tuner; the source and begins additional presses change play tuner band CD * Turns on system and issuesDisc SkipPlay/Pause command DVD * Turns on system and Playbegins play MP3 * Turns on system and Playbegins play Power Off Mute Powers system off (if AVR is current source, turns off AVRs multiroom system; if a device connected to the ABH hub is current source, turns off hub) Skip Up/ If source is: If source is: Down * - AVR – Preset Up - AVR – Preset Down (AB 2 only) - CD – Track Skip Up - CD – Track Skip Down - DVD – Next Chapter - DVD – Previous Chapter - MP3 – No effect - MP3 – No effect Volume Up Volume Up Increases volume Volume Volume Down Decreases volume Down System Off If Source 1 is playing, Not applicable (ABR turns off an A-BUS- Remote equipped product; if only) another source is playing, AVR remains on and ABH 4000 is turned off *These keys only affect the ABH hub and devices connected to it. The keypad itself offers local volume control and muting, and limited source control. For more sophisticated control over the AVR and source devices, point a remote at the IR sensor and enter the desired command. To turn off the AVRs multiroom system, select the AVR as the source and press and hold the Power Off key. The AVRs main listening area will not be affected. If the AB 2 is connected to an ABH hub, turn off the hub by selecting any source other than the AVR. Then press and hold the Power Off key. NOTE: Play/pause functionality may vary by model for Harman Kardon CD and DVD players. System power-off functionality may vary for remotes other than the one included with the AB 2. The operation of your AB 2 with a Harman Kardon AVRs second-zone remote may vary from model to model. Not all features will work with all models. Functions requiring press and hold are not available when a remote control is used. Due to technology advancements, the AB 2 may not operate as expected with older Harman Kardon products; connect those sources to an ABH 4000s analog inputs.
