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:
Step Four: Connect the speaker cable to the AB 1.
Connect speaker wires to the AB 1 module using the color-
code chart on the
Speaker Terminal Block £ as a guide.
Be careful to properly observe the positive (+) and negative (-“)
polarity indications, and to avoid having the wire strands from
one cable touch another.
Insert the wire into the terminal block. Tighten the retaining
screws to secure the wire.

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 1s
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.
Using the supplied mounting screws, attach the AB 1 to the
junction box or plaster ring through the
Screw Slots 2.

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 owners 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 1s amplifier
may be turned on by simply pointing the Zone II remote sup-
plied with the unit, or any remote pro
grammed with the proper
Harman Kardon IR codes, at the AB 1s
IR Sensor 4 and
pressing the remotes 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
turned up.
- Check for proper adjustments of the output level trims.
- Check the speaker connections.
If the receiver or other components do not respond to com-
mands from the AB 1 or a remote pointed at the AB 1:
- Make certain that the A-BUS/Ready receivers Multiroom
system has been turned on.
- Make certain that the Cat. 5/5e cable is properly connected
to both the AB 1 and receiver.
- Make certain that there is a proper connection between
the A-BUS/Ready receiver and any additional IR controlled
components.
- Make certain that the remote is properly programmed to
operate the receiver and other components.
