Important Safety and Installation Information

Low-voltage wiring systems must be properly installed to mini-

mize the possibility of accidental contact with hazardous power

and lighting wiring. Never place remote control wiring near bare

power wires or lightning rods,antennas, transformers,steam or

hot water pipes,or heating ducts. Never run low voltage wire in

any conduit, box, channel, duct or other enclosure containing

power or lighting circuits of any type.In addition to ensuring

proper separation between any AC power wiring and the

Category 5/5e cable used for A-BUS,®it is important to avoid

running the A-BUS cable in parallel to any AC wiring.Always

maintain at least the minimum separation between AC wiring

and the A-BUS cable or ANY low-voltage cable that is required

by the NEC or any applicable local building codes or regulations.

Make sure to follow all instructions when preparing wiring for

use with the AB 1 module.Failure to do so may result in a

potential safety hazard, including possible danger to persons

and/or equipment.

If you will be running the cable through a ventilation plenum,

remember

to use plenum-rated cable to comply with NEC and

other safety requirements.Failure to do so may result in a

potential fire or safety hazard.

Always observe the appropriate safety codes for concealed

wiring. Be extremely careful not to cut through or drill into con-

cealed wiring or pipes.Make a small inspection opening before

cutting or drilling.

Dust or dirt can cause special problems on wiring contacts.

Be sure all contacts are clean, and that all parts are installed

correctly to protect them from dust and dirt.

Your new Harman Kardon AB 1 Amplified In-Wall Module

has been custom-designed for use with Harman Kardon’s

A-BUS/Ready products and it is also compatible with other

A-BUS-compatible systems.Do not connect it to any

other device.

The AB 1 is only to be installed by qualified personnel and as

per the requirements of all applicable state and local building

codes,as well as NEC (National Electrical Code) requirements.

Check with your local authorities as needed to ensure that

all wiring inside walls is installed in compliance with the

proper standards.Failure to do so may present a potential

safety hazard.

If you have any doubt about your ability to work with electrical

and telecommunications wiring, you are advised to hire a

professional licensed electrician or custom installer to install

this product.

Installation Planning

The AB 1 may be installed in any location appropriate for stan-

dard in-wall electrical components.You are responsible for

selecting and properly installing an appropriate electrical junction

box or plaster ring. Be sure to check the fit of the box or ring

with the AB 1 before installation into the wall.

Since the AB 1 uses a built-in infrared sensor to relay com-

mands to the A/V receiver, be sure to avoid installing the AB 1

in an area subject to potential interference with the IR signal.

Possible sources of interference include plasma video displays,

dimmer-controlled lighting, bright sunlight, and reflective surfaces

such as mirrors or blank walls.You may wish to temporarily

place the component to be controlled using the sensor in the

proposed location in order to test the integrity of IR signals.

When determining the specific location for an AB 1,keep in

mind that it should be in a convenient place where it may be

operated manually, or that,when it is used with a remote con-

trol, the mounting position enables the built-in IR sensor to “see”

commands from any place in the room. In practice,the AB 1

may be mounted close to other wall switches,but remember

that the AB 1 should NEVER be installed in the same gang box

as any switch or product, such as a light switch or dimmer,

where AC line voltage is present.

When planning the installation, it is also wise to consider the

distance from the AB 1 module to the speakers,particularly

when they are in-wall or ceiling mounted. Be certain that there

are no solid walls or load-bearing structures that would prevent

the speaker wires from reaching their location.

The wiring used to connect the AB 1 to the A-BUS/Ready

receiver may be Category 5, 5e (or better) wiring.Be certain

that any safety requirements mandating the use of plenum

wiring are taken into account.The speaker wiring should also be

in-wall rated as required, and may not exceed 14 AWG.To sim-

plify wiring you may wish to use two-pair CL-3 rated in-wall

wiring and run a single cable from the AB 1 to both locations.

One pair will be used to connect the first speaker and the other

will continue to the second speaker.

Speaker Selection

The AB 1 is compatible with most modern in-wall or ceiling

speakers,provided that they have an efficiency rated at 88dB

or greater. Minimum speaker impedance is six ohms.

It is possible to run two pairs of speakers from one AB 1,

but we do not recommend that due to the degradation in

performance.

What Is Included

Your AB 1 in-wall module includes two mounting screws: self-

starting, universal-head machine screws.

You are responsible for providing a Decora-style wall-plate,

available in a variety of colors and finishes at your local hard-

ware retailer.

You are also responsible for providing the speakers and a

sufficient length of Category 5/5e (or better) UTP (unshielded

twisted pair) cable and an RJ-45 modular plug.The wiring

scheme is the standard TIA T568A configuration.The maximum

length should not exceed 150 feet in order to avoid degrading

the signal. Further information on the correct wiring configuration

is provided in these instructions.

¡Input Cable Connection Block – Using standard IDT

punch-down tools,connect the Category 5/5e cable linking the

AB 1 to the receiver to this connection block in accordance with

the color code printed on the circuit board.

™Output Level Trims – These trim pots are used to match

the output level of the AB 1 module to the specific speakers

in use.

£Speaker Terminal Block – The wire used to connect the

AB 1 to your speakers is connected to this terminal block. Insert

the wire in accordance with the color coding shown and then

tighten the screw.Note that the maximum wire size is 14 AWG.

Installation and Connection

IMPORTANT SAFETY NOTES:

• Before beginning the installation process, make certain

that all electronic products in the system are turned off

and disconnected from their A/V power connection.

This avoids the possibility of accidental activation,

which could possibly damage the equipment or cause

personal injury. Do not turn on the equipment until

instructed to do so.

• Be certain to observe all appropriate safety measures

when installing any wiring, including, but not limited to,

the use of eye protection when required, and attention

to the required distances between low-voltage wiring

and high-voltage AC mains wiring.

Step One: Run a Category 5/5e cable from the receiver

location to the module.

Run a splice-free Category 5/5e cable from the location where

the AB 1 module will be installed to the location where the

A-BUS/Ready receiver is placed.At each end, make certain to

leave sufficient wire for ease of installation.Any extra wire may

be trimmed back during the installation. Remember that you will

need to have access to the rear of the AB 1 after the module is

connected, but before the module is secured into the wall box.

Step Two: Prepare and install an RJ-45 plug at the

receiver end of the system.

The connection and cable termination at the receiver end of the

installation is a standard RJ-45 connector using the TIA T568A

configuration.

Connect an RJ-45 plug to the end of the wire as follows.

Looking at the connector with its clip down and the wires

coming out of the connector

toward you, numbered from left

to right, the typical pin colors are as follows:

Pin # Striped Wire Pairs Solid Wire Colors

1Screw Holes – After you have completed installation, these

screw holes accept the screws supplied with your Decora-style

wall plate to attach it to the AB 1.

2Screw Slots – Use the supplied machine screws to attach

the AB 1 to an electrical junction box or plaster ring through

these slots.

3Volume ⁄/¤Buttons – Pressing these buttons

raises or lowers the volume level of the speakers connected

to the AB 1.

4IR Sensor – This sensor receives signals from a remote

control, such as the Zone II remote supplied with Harman Kardon

multichannel-capable receivers,and passes them on to the

receiver or other compatible source components.

5Status LED –The LED behind the red window will light

when the AB 1 is connected to an A-BUS/Ready receiver

that is turned on. It is now ready to accept control commands,

as long as the AVR’s Multiroom system is activated.It will

flash when a command is received from a compatible

remote control.

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 5will 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 3on 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 3for 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.

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 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 pro

grammed with the proper

Harman Kardon IR codes, at the AB 1’s IR Sensor 4and

pressing the remote’s Power On button.

You may adjust the volume in the remote room by pressing the

Volume Up/Down Buttons 3on 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.
