Troubleshooting Guide
I
f the remote A-BUS modules do not operate at all:
Verify all connections between the remote modules and the ABH 4
• Check the RJ-45 connection between the ABH 4 and the host receiver
(A-BUS/
READY systems)
Check the AC power connection at both the ABH 4’s Power jack and on
t
he Power Supply
If the remote module’s status LED is lit but there is no sound:
• Make certain that an active source has been selected on the host receiver
Check the RJ-45 connection between the ABH 4 and the host receiver
(A-BUS/READY systems)
Check the audio connections between the ABH 4 and the host receiver
(
non-A-BUS/
READY s
ystems)

t
ion hints, please visit the Product Support section of the Harman Kardon Web

Operation
W
hen 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
b
een 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 4’s Power
S
upply into a non-switched AC outlet and turn on the host receiver, processor or
preamplifier. Operation of the ABH 4 is seamless, as the remote A-BUS modules
w
ill communicate directly with the host source.
When the ABH 4 is used with an A-BUS/
READY receiver, the A-BUS modules in
the remote room operate as if they were connected directly to the host receiver.
N
o further controls are needed. Follow the instructions included with the A-BUS
modules for operation information.
When the ABH 4 is used in the stand-alone mode with a source that is not
A-BUS/READY, the method of operation varies depending on the specifics of the
installation:
When a 12-volt adaptor is not connected to the ABH 4’s
S
tatus 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 module’s internal amplifier until an audio signal is sensed at the
ABH 4’s Audio Inputs £.
When a 12-volt adaptor is connected to the ABH 4’s
S
tatus Input
¡,
the
system is ready for full operation at all times, including pass-through of IR
commands from remote A-BUS modules as well as power to the remote
modules’ internal amplifiers.
The three LED indicators on the ABH 4 signify the following operational modes:
The
S
tatus Indicator
å l
ights when the system is activated either by con-
nection to an A-BUS/READY receiver that is turned on, when a signal is sensed
at the Audio Inputs £ or when a 12-volt 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
P
ower Indicator
l
ights when the AC Power Supply is connected to
the ABH 4 and/or when a connection is made between the ABH 4 and an
A-BUS/R
EADY
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
I
f your system requires that the remote A-BUS models are active and able to
receive commands when the host receiver, processor or preamplifier is not
t
urned on, connect an optional power supply to the
S
tatus 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
I
f you 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 manufacturer’s
i
nstructions.
Optional Step Seven: Remote IR Sensor Connection
If the source and control equipment is behind cabinet doors or dark glass and
y
ou 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+ +12V
S
IG IR OUT
GND GND
NOTE: The STAT connection is not used in standard installations.
I
f 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 Non-A-BUS/
READY
Product
T
he 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
r
equired 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 A-BUS and audio/video systems integration.
Step One: Connect an Audio Source
C
onnect the audio outputs of the source that will be used to feed the A-BUS
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.
T
he 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,
o
r it may be a direct connection to a single source such as a CD player or tuner.
Step Two: Connect the A-BUS Modules
Connect the RJ-45 jacks on the Cat. 5 cabling that runs to the remote room
m
odules to the
A
-BUS Outputs
o
n the ABH 4. Make certain that the con-
nector is wired in accordance with the standard TIA 568A color-coding. Connect
the A-BUS modules in the remote rooms to the cable in accordance with the
instructions for the module.
Step Three: Connect the AC Power Supply
C
onnect the AC Power Supply furnished with the ABH 4 to the
P
ower 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.
O
ptional 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 RJ-45
jumper cable supplied with the second ABH 4. Then, follow steps two and three
as shown above.

OTE:
T
he following steps provide additional options that extend the flexibility of
your A-BUS system. If you are not familiar with audio/video systems installations,
you may wish to have them completed by a properly trained installer.
