SAFETY INFORMATION
Important Safety Information
Verify Line Voltage Before Use
Your AVR 144 has been designed for use with 120-volt AC current. Connection to
a line voltage other than that for which it is intended can create a safety and fire
hazard and may damage the unit.
If you have any questions about the voltage requirements for your specific model, or
about the line voltage in your area, contact your selling dealer before plugging the unit
into a wall outlet.
Do Not Use Extension Cords
To avoid safety hazards, use only the power cord attached to your unit.We do not
recommend that extension cords be used with this product. As with all electrical
devices, do not run power cords under rugs or carpets or place heavy objects on
them. Damaged power cords should be replaced immediately by an authorized service
center with a cord meeting factory specifications.
Handle the AC Power Cord Gently
When disconnecting the power cord from an AC outlet, always pull the plug; never
pull the cord. If you do not intend to use the unit for any considerable length of time,
disconnect the plug from the AC outlet.
Do Not Open the Cabinet
There are no user-serviceable components inside this product. Opening the cabinet
may present a shock hazard, and any modification to the product will void your
guarantee. If water or any metal object such as a paper clip, wire or staple accidentally falls inside the unit, disconnect it from the AC power source immediately, and
consult an authorized service center.
CATV or Antenna Grounding
If an outside antenna or cable system is connected to this product, be certain that it is
grounded so as to provide some protection against voltage surges and static charges.
Section 810 of the National Electrical Code, ANSI/NFPA No. 70-1984, provides
information with
grounding of the lead-in wire to an antenna
tors, location of antenna discharge unit,
requirements of the grounding electrode.
NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call the CATV
(cable TV) system installer’s attention to article 820-40 of the NEC, which provides
guidelines for proper grounding and, in particular, specifies that the cable ground
shall be connected to the grounding system of the building, as close to the point
of cable entry as possible.
Installation Location
• To ensure proper operation and to avoid the potential for safety hazards, place the
unit on a firm and level surface. When placing the unit on a shelf, be certain that
the shelf and any mounting hardware can support the weight of the product.
• Make certain that proper space is provided both above and below the unit for
ventilation. If this product will be installed in a cabinet or other enclosed area,
make certain that there is sufficient air movement within the cabinet. Under some
circumstances, a fan may be required.
• Do not place the unit directly on a carpeted surface.
• Avoid installation in extremely hot or cold locations, or in an area that is exposed
to direct sunlight or heating equipment.
• Avoid moist or humid locations.
• Do not obstruct the ventilation slots on the top of the unit, or place objects
directly over them.
• Due to the weight of the AVR 144 and the heat generated by the amplifiers,
there is the remote possibility that the rubber padding on the bottom of the
respect to proper grounding of the mast and supporting structure,
discharge unit, size of grounding conduc-
connection to grounding electrodes and
unit’s feet may leave marks on certain wood or veneer materials. Use caution
when placing the unit on soft woods or other materials that may be damaged
by heat or heavy objects. Some surface finishes may be particularly sensitive to
absorbing such marks, due to a variety of factors beyond Harman Kardon's control, including the nature of the finish, cleaning materials used, and normal heat
and vibration caused by the use of the product, or other factors.We recommend
that caution be exercised in choosing an installation location for the component and
in normal maintenance practices, as your warranty will not cover this type of damage
to furniture.
Cleaning
When the unit gets dirty, wipe it with a clean, soft, dry cloth. If necessary, and only after
unplugging the AC power cord, wipe it with a soft cloth dampened with mild soapy
water, then a fresh cloth with clean water. Wipe it dry immediately with a dry cloth.
NEVER use benzene, aerosol cleaners, thinner, alcohol or any other volatile cleaning
agent. Do not use abrasive cleaners, as they may damage the finish of metal parts.
Avoid spraying insecticide near the unit.

audio so that louder passages are reduced in volume to avoid disturbing
others, while dialogue remains intelligible.
Track Skip: These buttons have no effect on the receiver, but are
used with many source components to change tracks or chapters.
Transport Controls: These buttons have no effect on the receiver,
but are used to control many source components. By default, when the
remote is operating the receiver, these buttons will control a DVD player.

INTRODUCTION TO HOME THEATER
The AVR 144 may be the first multichannel surround sound receiver you
have owned. Although it has more connections and features than older
two-channel receivers, many of the principles are similar and the new
concepts are easy to understand. This introductory section will help you
to familiarize yourself with the basic concepts, which will make setup and
operation smoother.
If you are already familiar with home theater, you may skip this section
and proceed to the Connections section on page 16.
Typical Home Theater System
A home theater typically includes your audio/video receiver, which controls the system; a DVD player; a source component for television broadcasts, which may be a cable box, a satellite dish receiver, an HDTV tuner
or simply an antenna connected to the TV; a video display (television);
and loudspeakers.
All of these components are connected using various types of cables for
audio and video signals.
Multichannel Audio
The main benefit of a home theater system is that several loudspeakers
are used in various locations around the room to produce “surround
sound.” Surround sound helps to immerse you in the musical or film
presentation for increased realism.
The AVR 144 may have up to five speakers connected directly to it
(plus a subwoofer). Each speaker is powered by its own amplifier channel inside the receiver. When more than two speakers are used, it is
called a multichannel system.
Front Left and Right – The main speakers are used the same way
•
as in a two-channel system. However, you may notice that in many
surround modes, these speakers are used more for ambient sound
while the main action is moved to the center speaker.
• Center – The center speaker is usually placed above or below the
video screen, and is used mostly for dialogue in movies and television
programs. This placement allows the dialogue to originate near the
actors’ faces, for a more natural sound.
• Surround Left and Right – The surround speakers are used to
improve directionality of ambient sounds. In addition, by using more
loudspeakers in the system, more dynamic soundtracks may be
played without risk of overloading any one speaker.
Many people expect the surround speakers to play as loudly as the
front speakers. Although all of the speakers in the system will be calibrated to sound equally loud at the listening position, most artists use
the surround speaker for ambient effects only, and they program their
materials to steer very little sound to these speakers.
Subwoofer – A subwoofer is a special-purpose speaker designed
•
to play only the lowest frequencies (the bass). It may be used to
augment smaller, limited-range satellite speakers used for the other
channels. In addition, many digital-format programs, such as movies
recorded in Dolby Digital, contain a special low-frequency effects
(LFE) channel which is directed only to the subwoofer. The LFE channel packs the punch of a rumbling train or airplane, or the power of
an explosion, adding realism and excitement to your home theater.
Many people use two subwoofers, placed on the left and right sides
of the room, for additional power and even distribution of the sound.
Surround Modes
There are different theories as to the best way to present surround
sound and to distribute soundtrack information among the various
speakers. A variety of algorithms have been developed in an effort to
accurately reproduce the way we hear sounds in the real world. The
result is a rich variety of surround mode options. Some modes are
selected automatically, depending on the signal being received from the
source. In many cases, you may select a surround mode manually.
Several companies have taken surround sound in slightly differing directions. It is helpful to group the numerous surround modes either by their
brand name, or by using a generic name:
Dolby Laboratories, Inc. Modes – Dolby Digital, Dolby Pro Logic II,
•
Dolby Virtual Speaker, Dolby Headphone
• DTS Modes – DTS, DTS Neo:6, DTS 96/24
• Harman International (Harman Kardon’s Parent Company) –
Logic 7
• DSP Modes – Generic modes that include Hall 1, Hall 2 and Theater
• Stereo Modes – Generic modes that expand upon conventional two-
channel stereo, including DSP Surround Off, Analog Bypass Surround
Off and 5-Channel Stereo
Table 4 on pages 39 – 41 contains detailed explanations of the differences between the various mode groups, and the mode options available within each group. Digital modes, such as Dolby Digital and DTS,
are only available with specially encoded programs, such as DVDs and
digital cable or satellite television. Other modes may be used with various digital and analog signals to create a different surround presentation, or to use a different number of speakers. Surround mode selection
depends upon the number of speakers in your system, the materials
you are watching or listening to, and your personal tastes. Feel free to
experiment.

There are different types of audio and video connections used to connect the receiver to the speakers and video display, and to connect
the source devices to the receiver. To make it easier to keep them all
straight, the Consumer Electronics Association (CEA) has established a
color-coding standard. Table 1 may be helpful to you as a reference
while you set up your system.
Table 1–Connection Color Guide
Types of Cables
This section will briefly review different types of cables and connections
that you may use to set up your system.
Speaker Connections
Speaker cables carry an amplified signal from the receiver’s speaker
terminals to each loudspeaker. Speaker cables contain two wire
conductors, or leads, inside plastic insulation. The two conductors are
usually differentiated in some way, by using different colors, or stripes,
or even by adding a ridge to the insulation. Sometimes the actual wires
are different, one being copper red and the other silver.
The differentiation is important because each speaker must be connected
to the receiver’s speaker-output terminals using two wires, one positive
(+) and one negative (–). This is called speaker polarity. It’s important to
maintain the proper polarity for all speakers in the system. If some speakers
have their negative terminals connected to the receiver’s positive
terminals, performance can suffer, especially for the low frequencies.
Always connect the positive terminal on the loudspeaker, which is usually
colored red, to the positive terminal on the receiver, which is colored as
shown in the Connection Color Guide (Table 1). Similarly, always connect the black negative terminal on the speaker to the black negative
terminal on the receiver.
The AVR 144 uses binding-post speaker
terminals that can accept banana plugs
Figure 1 – Binding-Post Speaker Terminals With Banana Plugs

or bare-wire cables.
Banana plugs are simply plugged into the
hole in the middle of the terminal cap.
See Figure 1.
Bare wire cables are installed as follows (see Figure 2):
1. Unscrew the terminal cap until the pass-through hole in the collar is
revealed.
2. Insert the bare end of the wire into the hole.
3. Screw the cap back into place until the wire is held snugly.
Figure 2 – Binding-Post Speaker Terminals With Bare Wires
Subwoofer
The subwoofer is a specialized type of loudspeaker that is usually connected in a different way. The subwoofer is used to play only the low
frequencies (bass), which require much more power than the other
speaker channels. In order to obtain the best results, most speaker
manufacturers offer powered subwoofers, in which the speaker contains
its own amplifier on board. Sometimes the subwoofer is connected to
the receiver using the front left and right speaker outputs, and then the
front left and right speakers are connected to terminals on the subwoofer. More often, a line-level (nonamplified) connection is made
from the receiver’s Subwoofer Output to a corresponding jack on the
subwoofer, as shown in Figure 3.
Although the subwoofer output looks similar to the analog audio jacks
used for the various components, it is filtered and only allows the low
frequencies to pass. Don’t connect this output to your other devices.
Although doing so won’t cause any harm, performance will suffer.
Figure 3 – Subwoofer
Connecting Source Devices to the AVR
The AVR 144 is designed to process audio and video input signals,
playing back the audio and displaying the video on a television or monitor connected to the AVR. These signals originate in what are known as
“source devices,” including your DVD player, CD player, DVR (digital
video recorder) or other recorder, tape deck, game console, cable or
satellite television box or MP3 player. Although the tuner is built into the
AVR, it also counts as a source, even though no external connections
are needed, other than the FM and AM antennas.
Separate connections are required for the audio and video portions of
the signal. The types of connections used depend upon what’s available
on the source device, and for video signals, the capabilities of your
video display.

Audio Connections
There are two formats for audio connections: digital and analog. Digital
audio signals are of higher quality, and are required for listening to
sources encoded with digital surround modes, such as Dolby Digital and
DTS. There are two types of digital audio connections commonly used:
coaxial and optical. Either type of digital audio connection may be used
for each source device, but never both simultaneously for the same
source. However, it’s okay to make both analog and digital audio connections at the same time, to the same source.
Digital Audio
Coaxial digital audio jacks are usually color-coded in orange. Although
they look similar to analog jacks, they should not be confused, and you
should not connect coaxial digital audio outputs to analog inputs or
vice versa. See Figure 4.
Figure 4 – Coaxial Digital Audio
Optical digital audio connectors are normally covered by a shutter to
protect them from dust. The shutter opens as the cable is inserted.Input
connectors are color-coded using a black shutter. See Figure 5.
Figure 5 – Optical Digital Audio
Due to the nature of digital signals as binary bits, they aren’t subject
to signal degradation the way analog signals are. Therefore, the quality
of coaxial and optical digital audio connections should be the same,
although it is important to limit the length of the cable. Whichever type of
connection you choose, Harman Kardon recommends that you always
select the highest quality cables available within your budget.
Multichannel analog connections are used with advanced sources where
the digital content is copy-protected and all surround processing is performed inside the source. These types of connections are usually used
with DVD-Audio, SACD, Blu-ray Disc, HD-DVD and other advanced
players. See Figure 7.
Figure 7 – Multichannel Analog Audio
Video Connections
Although some sources produce an audio signal only (e.g., CD player,
tape deck), many sources output both audio and video signals (e.g.,
DVD player, cable television box, HDTV tuner, satellite box, VCR, DVR).
In addition to the audio connection, you will need to connect one type of
video connection for each source (never more than one at the same
time for any source).
There are three types of analog video connections: composite video,
S-video and component video.
Composite video is the basic connection most commonly available.
The jack is usually color-coded in yellow, and looks like an analog audio
jack, although it is important never to confuse the two. Do not plug a
composite video cable into an analog or coaxial digital audio jack, and
vice versa. Both the chrominance (color) and luminance (intensity)
components of the video signal are transmitted using a single cable.
See Figure 8.
Analog Audio
Analog connections require two cables, one for the left channel (white)
and one for the right channel (red). These two cables are often attached
to each other for most of their length. See Figure 6.
Most sources that have digital audio jacks also have analog audio jacks,
although some older types of sources, such as tape decks, have only
analog jacks. For sources that are capable of both digital and analog
audio, you may wish to make both connections. If you wish to record
materials from DVDs or other copy-protected sources, you will only be
able to do so using analog connections. Remember to comply with all
laws regarding copyright, if you choose to make a copy for your own
personal use.

Figure 8 – Composite Video
S-video, or “separate” video, transmits the chrominance and luminance
components using separate wires contained within a single cable. The
plug on an S-video cable contains four metal pins, plus a plastic guide
pin. Be careful to line up the plug correctly when you insert it into the
jack on the receiver, source or video display. See Figure 9.
Figure 9 – S-Video
Component video separates the video signal into three components –
one luminance (“Y”) and two subsampled color signals (“Pb” and “Pr”) –
that are transmitted using three separate cables. The “Y” cable is colorcoded green, the “Pb” cable is colored blue and the “Pr” cable is colored red. See Figure 10.

If it’s available on your video display, component video is recommended as the best quality connection, followed by S-video and then
composite video.
Antennas
The AVR 144 uses separate terminals for the included FM and AM
antennas that provide proper reception for the tuner.
The FM antenna uses a 75-ohm F-connector. See Figure 11.
Figure 11 – FM Antenna
The AM loop antenna needs to be assembled. Then connect the two
leads to the screw terminals on the receiver. See Figure 12.

Before you begin to connect cables, it is important to set up your
speakers in their correct locations in the room.
Optimally, the speakers should be placed in a circle with the listening
position at its center. The distance from the listening position to the
video display forms the radius of the circle.
The speakers should be angled so that they directly face the listening
position.
The center speaker is placed either on top of, below or mounted on the
wall above or below the video display screen.
The front left and right speakers are placed along the circle, about 30
degrees from the center speaker and angled toward the listener.
It is best to place the front left/right and center speakers as close to the
same height as possible, preferably at about the same height as the listener’s ears. In any event, the center speaker should be no more than
two feet above or below the left/right speakers.
The side surround speakers should be placed 110 degrees from the
center speaker, that is, slightly behind and angled toward the listener. If
this isn’t feasible, place the surround speakers behind the listener, with
each surround speaker facing the opposite-side front speaker. The surround speakers may be placed a little higher than the listener’s ears.
The subwoofer’s location is less critical, since low-frequency sounds are
omnidirectional. Placing the subwoofer close to a wall or in a corner will
reinforce the low frequencies, and may create a “boomy” sound. You
may wish to experiment over time by placing the subwoofer where the
listener normally sits and then walking around the room until the low
frequencies sound best. Place the subwoofer in that spot.
NOTE: Your receiver will sound its best when the same model
loudspeaker is used for all positions (other than the subwoofer).
If that isn’t possible, try to use speakers made by the same
manufacturer.

INSTALLATION
You are now ready to connect your various components to your receiver.
Before beginning, make sure that all components, including the AVR 144,
are turned completely off and their power cords are unplugged. Don’t
plug any of the power cords back in until you have finished
making all of your connections.
Remember that your receiver generates heat while it is playing. Select a
location that leaves several inches of space on all sides of the receiver. It
is preferable to avoid completely enclosing the receiver inside a cabinet.
It is also preferable to stack components on separate shelves rather
than directly on top of the receiver. Some surface finishes are delicate.
Try to select a location with a sturdy surface finish.
Step One – Connect the Speakers
If you have not yet done so, place your speakers in the listening room
as described in the Speaker Placement section above.
Connect the center, front left, front right, surround left and surround right
loudspeakers to the corresponding speaker terminals on the AVR 144.
Remember to maintain the proper polarity by always connecting the
positive and negative terminals on each speaker to the positive and
negative terminals on the receiver. Use the Connection Color Guide
on page 16 as a reference. See Figure 14.
Figure 14 – Speaker Connections
Step Two – Connect the Subwoofer
Connect the Subwoofer Output on the AVR 144 to the line-level input on
your subwoofer. See Figure 15. Consult the manufacturer’s guide for the
