Note that one wire in each pair is always a solid color, and the other is either white or striped. Make sure that the twisted pairs of wires consist of those attached to pins 1 and 2, pins 3 and 6, pins 4 and 5, and pins 7 and 8.
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 cer- tain 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 1.
Once the wire is run to the remote location where the AB 1 will be installed, connect the Category 5/5e cable to the AB 1. 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 nick the 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 Insulation Displacement Terminal (IDT) tools and procedures. DO NOT use screwdrivers to insert the wire into the IDT connection points. Also, take special care to make certain that there are no shorts between any of the individual wires, as this may cause damage to the AB 1. From left to right, the connections are made
as follows:
• Brown
• White w/Brown Stripe
• Blue
• White w/Blue Stripe
• Green
• White w/Green Stripe
• Orange
• White w/Orange Stripe
Step Five: Connecting the AB 1 to the
A-BUS/Ready product.
To set the output trims, the AB 1 must first be connected to the A-BUS/Ready receiver. After first checking to make certain that the connections to the speaker cable and Cat. 5/5e cable have properly been made, plug the RJ-45 jack at the receiver end of the cable into the A-BUS jack on the back of the A-BUS/Ready receiver.
Next, turn on the receiver and make any adjustments required to turn on the Multiroom system and send an active source to the output. As a confirmation that the connections have been made and that receiver is on, the Status LED 5 will light up. So that the level adjustments are as accurate as possible, select a program source or music type that is representative of what will most often be listened to in the room where the A-BUS module will be installed.
Step Six: Adjust the output levels.
This step sets the level adjustments for the AB 1. Once this process is complete, all further volume settings are made with the Volume Up/Down Buttons 3 on the AB 1, the Zone II remote, or an optional third-party remote that is programmed for Harman Kardon products.
With the Multiroom system activated and a source playing, press the Volume Up Button 3 for 20 seconds so that the AB 1’s volume is set at its maximum. Next, adjust each of the Output Level Trims ™ until 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/ Ready receiver and AB 1. Before proceeding further, lower the volume back to normal listening level using the Volume Down Button 3.
Step Seven: Install the AB 1.
Place the AB 1 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.
Attach a Decora-style wall plate (not included) through the AB 1’s Screw Holes 1. Although any color Decora wall plate may be used with the AB 1, the AB 1 itself should not be painted.
Operation
Once the AB 1 is properly connected and the levels have been set, operation is simple.
In order to use the AB 1 module, the A-BUS/Ready receiver must be turned on and placed in the Multiroom mode. The procedure for doing this will vary from model to model, so we suggest that you consult the owner’s manual for your receiver for the correct instructions. As long as the receiver is powered up, and the Multiroom system is turned on, the AB 1’s amplifier may be turned on by simply pointing the Zone II remote sup- plied with the unit, or any remote programmed with the proper Harman Kardon IR codes, at the AB 1’s IR Sensor 4 and pressing the remote’s Power On button.
You may adjust the volume in the remote room by pressing the Volume Up/Down Buttons 3 on the AB 1 or with the vol- ume control buttons on the remote. The remote may also be used to operate the receiver to change sources and make other adjustments, such as changing the station on the tuner. When the proper IR codes are programmed in the remote being used, you may also operate compatible source components, such as CD or DVD players, that are connected to the IR remote output jack on the receiver.
To turn the remote room feed off, press the OFF button on the Zone II or other properly programmed remote.
Troubleshooting Guide
If you cannot hear any sound from the speakers connected to the AB 1:
• Make certain that the Cat. 5/5e cable is properly connected |
to both the AB 1 and receiver. |
• Make certain that the receiver is turned on and that the |
Multiroom mode is properly activated. |
• Make certain that any needed volume-level adjustments on |
the receiver are properly made. |
• Make certain that the volume control on the AB 1 is |
Other notes on using the AB 1 and other A-BUS products with Harman Kardon A-BUS/Ready receivers:
•When using the AB 1 with Harman Kardon A-BUS/Ready products, you may connect only one AB 1 at a time unless optional, external A-BUS-powered hub equipment is used.
•If A-BUS keypads or other A-BUS accessories not specifically designed for use with Harman Kardon products are used, their operation may be slightly different than with the AB 1. Consult the support area of the Harman Kardon Web site at www.harmankardon.com.
