Introduction
Thank you for choosing Harman Kardon!
With the purchase of a Harman Kardon AVR 155
you are about to begin many years of listening
enjoyment. Designed to provide all the excitement
and detail of movie soundtracks and every nuance
of musical selections, the AVR is truly a multichannel receiver for the new millennium. In addition to
the traditional 5.1 digital decoding modes such as
Dolby Digital and DTS, it offers the latest advancements in surround technology such as Dolby Pro
Logic II, the full suite of DTS modes, DTS Neo:6
and the latest 5.1 channel versions of Harman's
own Logic 7 technology.
The AVR has been engineered so that it is easy
to take advantage of all the power of its digital
technology. On-screen menus, fully color coded
connection jacks and terminals make installation
fast and simple. However, to obtain the maximum enjoyment from your new receiver, we urge
you to read this manual. A few minutes spent
learning the functions of the various controls will
enable you to take advantage of all the power
the AVR is able to deliver.
If you have any questions about this product, its
installation or its operation, please contact your
retailer or custom installer. They are your best
local sources of information.
Description and Features
The AVR 155 is among the most versatile and
multifeatured A/V receivers available, incorporating a wide range of listening options. In addition
to Dolby Digital and DTS decoding for digital
sources, a broad choice of surround modes for
Matrix surround-encoded or Stereo recordings are
available for use with sources such as CD, VCR, TV
broadcasts and the AVR’s own FM/AM tuner.
Along with Dolby Digital, Dolby Pro Logic II, DTS
Neo:6, DTS 96/24, Dolby 3 Stereo, 5 Channel
Stereo and Hall and Theater modes, the AVR offers
Harman International’s exclusive Logic 7 process
in 5.1 versions to create a wider, more enveloping
field environment and more defined fly-overs and
pans.
Dolby Virtual Speaker is available to create
enveloping sound fields from front left and right
speakers, and the latest Dolby Headphone
circuitry creates an amazing sense of openness
with headphones.
In addition to providing a wide range of listening
options, the AVR is easy to configure so that it
provides the best results with your speakers and
specific listening-room environment.
A Stereo-Direct mode bypasses the digital processor to preserve all of the subtleties of older analog,
two-channel materials, while bass management,
available in the surround and Stereo-Digital
modes,improves your ability to tailor the sound to
suit your room acoustics or taste.
The AVR 155 takes the “video” part of its name
seriously. Along with three HDMI inputs and two
100MHz analog component video inputs, the
AVR 155 provides A/V sync delay so that the lip
sync errors – commonly seen when digital video
processing is used in a source, program or video
display – are eliminated. For the ultimate in flexibility, the AVR features connections for three video
devices, all with both composite and S-Video
inputs. Two additional audio inputs are available,
and a total of four digital inputs and two outputs
make the AVR 155 capable of handling all the
latest digital audio sources.
For compatibility with the latest HDTV video
sources and progressive scan DVD players, the
AVR also features wide-bandwidth, low-crosstalk
component video switching.
Coax and optical digital outputs are available for
direct connection to digital recorders. A video
recording output and a color-coded six-channel
input make the AVR 155 virtually future-proof,
with everything needed to accommodate to morrow’s new formats right on board.
An important addition to the AVR 155’s impressive list of features is EzSet/EQ
™
, which automates the configuration process to make it quicker, easier and more precise. Using the special
microphone supplied with the unit, EzSet/EQ
takes the guesswork out of entering speaker
“size” and crossover information, delay times for
all channels and output levels. In addition to the
configuration settings, EzSet/EQ also includes
room equalization so that the signals sent to
each speaker are tailored to provide accurate
sonic quality with your specific combination of
speaker type, room size and other factors that
influence room acoustics. With EzSet/EQ, your
system is custom-configured in a few minutes
with accuracy that previously required expensive
and hard-to-use test equipment.
In tandem with EzSet/EQ, the AVR 155 includes a
full set of manual configuration settings for those
who wish to custom-trim their system even further. A Triple Crossover bass management system
makes it possible to enter different crossover settings for each speaker group.
The AVR 155’s powerful amplifier uses traditi onal
Harman Kardon high-current design technologies
to meet the wide dynamic range of any program
selection.
Harman Kardon invented the high- fidelity receiver
more then fifty years ago. With state-of-the-art
circuitry and time-honored circuit designs, the
AVR 155 is the perfect combination of the latest
in digital audio technology, a quiet yet powerful
analog amplifier in an elegant, easy-to-use package.

Important Safety Information
READ THIS BEFORE OPERATING
YOUR UNIT
Do not install this equipment in a confined space
such as a case or similar – away from direct
sunlight, heat sources, vibration, dust, moisture,
and/or cold. Avoid installing this unit where foreign object may fall onto this unit and/or this unit
may be exposed to liquid dripping or splashing.
On the top of this unit, do not place:
– Burning objects (i.e. candles), as they may
cause fire, damage to this unit, and/or personal
injury.
– Containers with liquid in them, as they may fall
and liquid may cause electrical shock to the
user and/or damage to this unit.
Do not cover this unit with a newspaper, tablecloth, curtain, etc. in order not to obstruct heat
radiation. If the temperature inside this unit rises,
it may cause fire, damage to this unit, and/or personal injury.
Install this unit near the AC outlet and where the
AC power plug can be reached easily.
This unit is not disconnected from the AC power
source as long as it is connected to the wall outlet, even if this unit itself is turned off. This state is
called the standby mode. In this state, this unit is
designed to consume a very small quantity of
power.
WARNING. TO REDUCE THE RISK OF FIRE
OR ELECTRIC SHOCK, DO NOT EXPOSE THIS
APPLIANCE TO RAIN OR MOISTURE.
Verify Line Voltage Before Use
Your AVR has been designed for use with
220-230-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
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 depot 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 a staple accidentally falls inside the unit, disconnect it from
the AC power source immediately, and consult an
authorized service station.
Installation Location
n To assure 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.
n 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.
n Do not place the unit directly on a carpeted
surface.
n Avoid installation in extremely hot or cold
locations, or an area that is exposed to direct
sunlight or heating equipment.
n Avoid moist or humid locations.
�
n Do not obstruct the ventilation slots on the
top of the unit, or place objects directly over
them.
n Due to the weight of the AVR 155 and the heat
generated by the amplifiers, there is the remote
possibility that the rubber padding on the
bottom of the 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, wipe it with a soft
cloth dampened with mild soapy water, then a
fresh cloth with clean water. Wipe dry im mediately 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.
Moving the Unit
Before moving the unit, be certain to disconnect
any interconnection cords with other compo nents, and make certain that you disconnect the
unit from the AC outlet.
Unpacking
The carton and shipping materials used to protect your new receiver during shipment were
specially designed to cushion it from shock and
vibration. We suggest that you save the carton
and packing materials for use in shipping if you
move, or should the unit ever need repair.
To minimize the size of the carton in storage, you
may wish to flatten it. This is done by carefully
slitting the tape seams on the bottom and
collapsing the carton. Other cardboard inserts
may be stored in the same manner. Packing
materials that cannot be collapsed should be
saved along with the carton in a plastic bag.
If you do not wish to save the packaging
materials, please note that the carton and other
sections of the shipping protection are recyclable.
Please respect the environment and discard
those materials at a local recycling center.
It is important that you remove the protective
plastic film from the front-panel lens. Leaving the
film in place will affect the performance of your
remote control.

Main Remote Control Functions
INSTALLATION AND CONNECTIONS 13
ENGLISH
Installation and Connections
After unpacking the unit, and placing it on a solid
surface capable of supporting its weight, you will
need to make the connections to your audio and
video equipment.
Audio Equipment Connections
We recommend that you use high-quality interconnect cables when making connections to
source equipment and recorders to preserve the
integrity of the signals.
When making connections to audio source
equipment or speakers it is always a good
practice to unplug the unit from the AC wall
outlet. This prevents any possibility of
accidentally sending audio or transient signals to
the speakers that may damage them.
1. Connect the analog output of a CD player to
the CD inputs
6
.
NOTE: When the CD player has both fixed and
variable audio outputs it is best to use the fixed
output unless you find that the input to the
receiver is so low that the sound is noisy, or so
high that the signal is distorted.
2. Connect the analog Play/Out jacks of a
cassette deck, MD, CD-R or other audio recorder
to the Tape Input jacks
2
. Connect the analog
Record/In jacks on the recorder to the Tap e
Output jacks
3
on the AVR.
3. Connect the digital output of any digital
sources such as a CD or DVD changer or player,
advanced video game, a digital satellite receiver,
HDTV tuner or digital cable set-top box or the
output of a compatible computer sound card to
the Optical and Coaxial Digital Inputs
RN*Ó
.
We recommend connecting the coaxial digital
audio output of your DVD player to the Coax 1
Digital Audio Input
N
, since that digital input
is assigned to the DVD source by default.
The Video 2/Cable/Sat source defaults to the
Optical 1 Digital Audio Input
R
. If your
cable television set-top box or satellite receiver is
equipped with an optical digital audio output,
we recommend that you connect it to this input
to obtain the benefits of higher-quality digital
audio (such as PCM, Dolby Digital 2.0 or Dolby
Digital 5.1 signals when broadcast by your cable
or satellite provider).
4. Connect the Coaxial or Optical Digital
Outputs
A
on the rear panel of the AVR to the
matching digital input connections on a CD-R or
MiniDisc recorder.
5. Assemble the AM Loop Antenna supplied with
the unit as shown below. Connect it to the AM
and GND screw terminals
0
.
6. Connect the supplied FM antenna to the FM
(75 ohm) connection
1
. The FM antenna may
be an external roof antenna, an inside powered
or wire lead antenna or a connection from a
cable system. Note that if the antenna or
connection uses 300-ohm twin-lead cable, you
should use a 300-ohm-to-75-ohm adapter to
make the connection.
7. Connect an MP3 player, iPod or portable CD to
the Aux In minijack audio input to listen to music
through the AVR 155. Usually the headphone
jack on the portable player is the only one that
can be used, and you have to adjust the volume
to be at a reasonable level on the portable unit
as well as on the AVR 155. If a fixed Line Out
jack or dual phono plug output jacks are available, using these with the proper cables may
result in better sound quality.
8. Connect the front, center and surround
speaker outputs
DEF
to the respective
speakers.
To assure that all the audio signals are carried to
your speakers without loss of clarity or resolution,
we suggest that you use high-quality speaker
cable. Many brands of cable are available and the
choice of cable may be influenced by the distance
between your speakers and the receiver, the type
of speakers you use, personal preferences and
other factors. Your dealer or installer is a valuable
resource to consult in selecting the proper cable.
Regardless of the brand of cable selected, we recommend that you use a cable constructed of fine,
multistrand copper with an area greater than 2 mm
2
.
Cable with an area of 1.5 mm
2
may be used for
short runs of less than 4 m. We do not recommend that you use cables with an area less than
1mm
2
due to the power loss and degradation in
per for mance that will occur.
Cables that are run inside walls should have the
appropriate markings to indicate listing with any
appropriate testing agency standards. Questions
about running cables inside walls should be
referred to your installer or a licensed electrician
who is familiar with the applicable local building
codes in your area.
When connecting wires to the speakers, be
certain to observe proper polarity. Note that the
positive (+) terminal of each speaker connection
now carries a specific color code as noted on
page 8. However, most speakers will still use a
red terminal for the postive (+) connection.
Connect the “negative” or “black” wire to the
same terminal on both the receiver and the
speaker.
NOTE: While most speaker manufacturers
adhere to an industry convention of using black
terminals for negative and red ones for positive,
some manufacturers may vary from this con figura tion. To assure proper phase and optimal
performance, consult the identification plate on
your speaker or the speaker’s manual to verify
polarity. If you do not know the polarity of your
speaker, ask your dealer for advice before proceeding, or consult the speaker’s manufacturer.
We also recommend that the length of cable
used to connect speaker pairs be identical. For
example, use the same length piece of cable to
connect the front-left and front-right or
surround-left and surround-right speakers, even
if the speakers are a different distance from the
AVR.
9. Connections to a subwoofer are normally
made via a line level audio connection from the
Subwoofer Output
4
to the line-level input
of a subwoofer with a built-in amplifier. When a
passive subwoofer is used, the connection first
goes to a power amplifier, which will be
connected to one or more subwoofer speakers. If
you are using a powered subwoofer that does
not have line-level input connections, follow the
instructions furnished with the speaker for
connection information.
10. If an external multi-channel audio source
with 5.1 outputs such as an external digital
processor/decoder, DVD-Audio or SACD player is
used, connect the outputs of that device to the
6-Channel Direct Inputs
9
.
Video Equipment Connections
Video equipment is connected in the same manner
as audio components. Again, the use of highquality interconnect cables is recommended to
preserve signal quality. To ensure best video performance S-Video sources should be connected
to the AVR only with their S-Video In/Outputs,
not with their composite video connectors too.
1. Connect a VCR’s audio and video Play/Out
jacks to the Video 2 In jacks
MO
on the rear
panel. The Audio and Video Record/In jacks on
the VCR should be connected to the Video 1
Out jacks
P7
on the AVR.
2. Although any video device may be connected
to these jacks, we recommend connecting your
TV to the Audio 1 Audio/Video Input Jacks
HQ
so that you may take advantage of the fact
that the remote control is preprogrammed with
TV product codes for the Video 1 device.
For the same reason, we recommend connecting
your video recorder, cable TV converter or
satellite receiver to the Video 2 Audio/Video
Input Jacks
MO
.
3. Connect the analog audio and video
outputs of a DVD or laser disc player to the
DVD jacks
5C
.
14 INSTALLATION AND CONNECTIONS
Installation and Connections
• If your video display has component video
inputs (Y/Pr/Pb), connect the Component
Video Outputs
K
.
• If your display does not have digital or
component video inputs, connect the Video
Monitor Output
B
on the AVR to the
matching input on your display. Only one
connection is needed, and S-video is the higher
quality signal.
HDMI Connections
HDMI™is the abbreviation for High-Definition
Multimedia Interface, which is quickly becoming
the standard connection point between
advanced video/audio source products and
displays, particularly for high-definition video
signals. HDMI is a digital connection, eliminating
the need to convert signals back and forth from
digital to analog.
Some source or display components in your
system may use DVI (Digital Video Interface) for
digital video connections. DVI carries the same
digital video signals as HDMI but uses a larger
connector and does not transport audio or
control signals. In most cases, you may mix and
match DVI and HDMI digital video connections
by using optional connector adapters. Note,
however, that some DVI-equipped video displays
are not compatible with the HDCP copy
protection coding that is increasingly carried with
signals connected via HDMI. If you have an
HDMI source and a DVI-equipped display, you
may occasionally be unable to view a program if
the display does not include HDCP. This is not the
fault of the AVR or your source; it simply
indicates that the video display is not
compatible.
The AVR 155 is equipped for HDMI switching,
which means that it is able to select either of the
three HDMI inputs as the source that feeds your
system’s video display. This preserves the digital
signal in its original form by passing it directly
through from source to display. However, this
also means that the AVR does not have access to
the signal and thus it is not able to add menus or
on-screen messages to HDMI signals, or to
process the audio that may be part of the signal
in an HDMI connection.
Therefore, the following connections are required
when the AVR 155 is used with HDMI sources:
• Connect the HDMI output of a source to either
of the HDMI Inputs
V
.
• Connect the HDMI Output
W
of the AVR to
an HDMI input on your display.
• Connect either an optical or coaxial digital
audio output from the source to the AVR. The
default connections are Coaxial 2
N
for a
source connected to HDMI 1
V
and
Optical 2
R
for a source connected to
HDMI 2
V
. You may use any digital or analog
audio source in conjunction with the HDMI
inputs, but if it varies from the default you
must make a change to the input’s setting, as
shown on page 18.
• Even when HDMI inputs are used, it is important to make sure that a component, S-video
or composite video connection is made
between the AVR and your display. This is
needed to view both the setup menus and onscreen messages, and to view other (nonHDMI) video sources. The AVR 155 does not
convert analog video signals to HDMI.
• All component inputs/outputs can be used for
RGB signals too, in the same way as described
for the Y/Pr/Pb signals, then connected to the
jacks with the corresponding color.
But this is only correct as long as only the
three RGB video signals are output by the
video source, with a sync signal in the "G"
signal only, without any sync signal output
separately by the source.
SCART A/V Connections
For the connections described above your video
device needs RCA (cinch) connectors or/and SVideo connectors for all Audio and Video signals:
Any normal video device (Not SVHS or High 8)
for only playback needs 3 RCA jacks, VCRs for
record and playback even 6 RCA jacks. Any
S-Video device (SVHS, High 8) needs 2 RCA
(Audio) and 1 S-Video jack (Video), if it´s a playback unit, or 4 RCA (Audio In/Out) and 2 S-Video
(Video In/Out) jacks, if it´s a recording VCR.
Many european video devices are equipped with
RCA (Cinch) or S-Video jacks only partially, not
for all audio and video in/outputs needed as
described above, but with a so called Scart or
Euro-AV connector (almost rectangular jack with
21 pins, see drawings on next page).
In that case the following Scart to Cinch
adapters or cables are needed:
• Units for playback, such as satellite receivers,
camcorders, DVD or LD players, need an
adapter from Scart to 3 RCA plugs, see fig. 1
(normal video devices) or from Scart to 2
RCA+1 S-Video plugs, see fig. 4 (S-Video
devices).
• HiFi VCRs need an adapter from Scart to 6 RCA
plugs, see fig. 2 (normal video), or from Scart
to 4 Audio+2S-Video jacks, see fig. 5
(S-Video VCR). Read carefully the instruction
attached to the adapter to find which of the six
plugs is used for the record signal to the VCR
(connect with the AVR´s Out jacks) and for the
playback signal from the VCR (connect with
the AVR´s In jacks). Do not misconnect Audio
and Video signals. Don´t hesitate to consult
your dealer, if you are uncertain.
4. Connect the digital audio outputs of a CD,
MD or DVD player, satellite receiver, cable box or
HDTV converter to the appropriate Optical or
Coaxial Digital Inputs
RN*Ó
.
Remember that the DVD source defaults to the
Coaxial 1 Digital Input
N
. All other sources
default to their analog inputs, although any
source may be assigned to any digital audio
input on the receiver.
NOTE: When connecting a device such as a
digital cable box or other set-top tuner product
with a digital audio output, we recommend that
you connect both the digital and analog outputs
of the product to your AVR. The audio input
polling feature of the AVR will then be able to
make certain that you have a constant audio
feed, since it will automatically switch the audio
input to the analog jacks if the digital feed is
interrupted or not available for a particular
channel.
5. Connect the Composite and S-Video (if
S-Video device is in use) Monitor Output
B
jacks on the receiver to the composite and
S-Video input of your television monitor or video
projector.
6. If your DVD player and monitor both have
component video connections, connect the component outputs of the DVD player to the Video
1 Component Video Inputs
L
. Note that
even when component video connections are
used the audio connections must still be made
to either the analog DVD Audio Inputs
5
or
any of the Coaxial or Optical Digital Input
jacks
NR
.
7. If another component video device is available, connect it to the Video 2 Component
Video Input jacks
J
. The audio connections
for this device should be made to either the
Video 2 Input jacks
O
or any of the Coaxial
or Optical Digital Input jacks
NR
.
8. If the component video inputs are used,
connect the Component Video Output
K
to
the component video inputs of your TV, projector
or display device.
9. If you have a camcorder, video game or other
audio/video device that is connected to the AVR
on a temporary, rather than permanent basis,
connect the audio, video and digital audio outputs of that device to the Front Panel Inputs
*ÓÔ
. A device connected to the Video 3
jacks
Ô
is selected as the Video 3 input, and
connected to the digital jacks
*Ó
it is
selected as "Optical 3" or "Coaxial 3" input.
(See page 18 for more information on input
configuration.)
10. Connect the AVR to your video display using
one of the following connections, even if you will
also use an HDMI connection:
INSTALLATION AND CONNECTIONS 15
ENGLISH
Installation and Connections
• If you use only normal video devices the TV
monitor needs an adapter from 3 RCA plugs to
Scart (fig. 3) only. If also S-Video devices are
used an adapter from 2 RCA+1S-Video plugs
to Scart is needed additionally (fig. 6),
connected to the SCART input on your TV that
is provided for S-Video.
Note that only the video plugs (the "yellow"
cinch plug in fig. 3 and the S-Video plug in
fig. 6) must be connected to the TV Monitor
Output
B
, and the volume on the TV must be
reduced to minimum.
Important Note for Adapter Cables:
If the cinch connectors of the adapter you’ll use
are labeled, connect the Audio and Video ”In”
plugs with the corresponding Audio and Video
”In” jacks on the AVR (and with a VCR connect
the ”Out” plugs to the ”Out” jacks on the VCR).
Note that with some adapter types it may be just
turned around: If no signal is audible/visible when
the VCR is playing connect the “Out” plugs to the
”In” jacks on the AVR and turned around. If the
adapter plugs are not labeled in that way, pay
attention to the signal flow directions as shown
in the diagrams above and in the instruction
attached to the adapter. If uncertain, don’t hesitate to consult your dealer.
Important Notes for S-Video connections:
Only the S-Video In/Out of S-Video devices must
be connected to the AVR, NOT both, normal video
and S-Video In/Outputs (except the TV, see item
below).
When both connections are made, only the
S-Video signal will be viewed on the screen.
Important Note for the Use of
SCART-Cinch Adapters:
When video sources are connected to the TV
directly with a SCART cable, specific control
signals apart from Audio/Video signals will be fed
to the TV. These specific signals are: With all video
sources, the signal for automatic input selection
that switches the TV automatically to the appropriate input as soon as the video source is started. And with DVD players, the signals automatically turning the TV to 4:3/16:9 format (with 16:9
TVs or with 4:3 TVs with selectable 16:9 format)
and turning the RGB video decoder of the TV on
or off, depending on the DVD player´s setting.
With any adapter cable, these control signals will
be lost and the appropriate setting of the TV must
be made manually.
Note for RGB signal with SCART:
If you use a unit providing RGB signals on a
SCART output (as e.g. most DVD players do) and
you want to use that RGB signal, this SCART output must be connected directly to your TV.
Al though the AVR can switch three-way video
signals (like component signals Y/Pb/Pr), most TVs
need separate sync signals for RGB (also with
SCART) that cannot be switched and provided by
the AVR. RGB signals can be pathed through the
AVR only when no separate sync signal is needed
(see last ”Video Connection Note” on page 14).
Power Connections
AC Power Connections
This unit is equipped with one accessory AC outlet. It may be used to power Accessory devices,
but it should not be used with high-current draw
equipment such as power amplifiers. The total
power draw to the Switched
G
Outlet must
not exceed 50 watts.
The Switched
G
outlet will receive power only
when the unit is on completely. This is recommended for devices that have no power switch
or a mechanical power switch that may be left in
the “ON” position.
NOTE: Many audio and video products go into a
Standby mode when they are used with switched
outlets, and cannot be fully turned on using the
outlet alone without a remote control command.
Once the power cord is connected, you are
almost ready to enjoy the AVR 155’s incredible
power and fidelity!

16 INSTALLATION AND CONNECTIONS
Installation and Connections
Speaker Selection
No matter which type or brand of speakers is
used, the same model or brand of speaker
should be used for the front-left, center and
front-right speakers. This creates a seamless
front soundstage and eliminates the possibility
of distracting sonic disturbances that occur when
a sound moves across mismatched front-channel
speakers.
Speaker Placement
The placement of speakers in a multichannel
home-theater system can have a noticeable
impact on the quality of sound reproduced.
Depending on the type of center-channel
speaker in use and your viewing device, place
the center speaker either directly above or below
your TV, or in the center behind a perforated
front-projection screen.
Once the center-channel speaker is installed,
position the left-front and right-front speakers so
that they are as far away from one another as
the center-channel speaker is from the preferred
listening position. Ideally, the front-channel
speakers should be placed so that their tweeters
are no more than 60cm above or below the
tweeter in the center-channel speaker.
They should also be at least 0.5 meter from your
TV set unless the speakers are magnetically
shielded to avoid colourings on the TV screen.
Note that most speakers are not shielded, even
with complete surround sets only the Center
speaker may be.
Depending on the specifics of your room
acoustics and the type of speakers in use, you
may find that imaging is improved by moving the
front-left and front-right speakers slightly forward of the center-channel speaker. If possible,
adjust all front loudspeakers so that they are
aimed at ear height when you are seated in the
listening position.
Using these guidelines, you’ll find that it takes
some experimentation to find the correct
location for the front speakers in your particular
installation. Don’t be afraid to move things
around until the system sounds correct. Optimize
your speakers so that audio transitions across
the front of the room sound smooth.
When the AVR is used in 5.1-channel operation,
the preferred location for surround speakers is
on the side walls of the room, at or slightly
behind the listening position.
Subwoofers produce largely nondirectional
sound, so they may be placed almost anywhere
in a room. Actual placement should be based on
room size and shape and the type of subwoofer
used. One method of finding the optimal
location for a subwoofer is to begin by placing it
in the front of the room, about 15 cm from a
wall, or near the front corner of the room.
Another method is to temporarily place the
subwoofer in the spot where you will normally
sit, and then walk around the room until you
find a spot where the subwoofer sounds best.
Place the subwoofer in that spot. You should
also follow the instructions of the subwoofer’s
manufacturer, or you may wish to experiment
with the best location for a subwoofer in your
listening room.
