Each precaution in this manual should be followed during servicing.

Components identified with the IEC symbol in the parts list are special significance to safety. When replacing a component identified with

, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the

parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably

insulated from the supply circuit before retuming the product to the customer.

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called

Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and

semiconductor "chip" components.

The following techniques should be used to help reduce the incidence of component damage caused by static electricity.

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on

your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device,

which should be removed for potential shock reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to

prevent electrostatic charge build-up or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static" can generate electrical charges

sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement

ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.)

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the

chassis or circuit assembly into which the device will be installed.

Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together

or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.

CAUTION :

SAFETY PRECAUTIONS

The following check should be performed for the continued

protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground (water

pipe, conduit, etc.) by connecting a leakage current tester

between the earth ground and all exposed metal parts of the

appliance (input/output terminals, screwheads, metal

overlays, control shaft, etc.). Plug the AC line cord of the

appliance directly into a 120V AC 60Hz outlet and turn the

AC power switch on. Any current measured must not exceed

o.5mA.

ANY MEASUREMENTS NOT WITHIN THE LIMITS

OUTLINED ABOVE ARE INDICATIVE OF A

POTENTIAL SHOCK HAZARD AND MUST BE

CORRECTED BEFORE RETURNING THE APPLIANCE

TO THE CUSTOMER.

is a component where a playback signal originates, such as DVD,

cable TV, satellite or the tuner.

Volume Knob: Turn this knob to raise or lower the volume.

Message Display: Various messages appear in this two-line display

in response to commands and changes in the incoming signal. In normal

operation, the current source name appears on the upper line, while

the surround mode is displayed on the lower line. When the on-screen

display menu system (OSD) is in use, the current menu settings appear.

Headphone Jack/EzSet/EQ Microphone Input: Plug a 1/4"

headphone plug into this jack for private listening.

This jack is also used to connect the supplied microphone for the

EzSet/EQ procedure described in the Initial Setup section. To begin

and one type of video connection.

NOTES:

• Each of these connections (analog audio, digital audio and

video) may be independently assigned to any source. See the

Initial Setup section for information on setting up sources,

including assigning audio and video inputs to a source.

• The AVR’s menus refer to these jacks as the Optical Front,

Coaxial Front, Composite Front, S-Video Front and Analog

Front inputs.

Speaker/Channel Input Indicators: The box icons indicate

which speaker positions you have configured (see the Initial Setup

Section), and the size (frequency range) of each speaker. The letters

will light inside the boxes to indicate which channels are present in

the incoming signal.

Navigation: These buttons are used to navigate the AVR’s menus

and to operate the tuner.

Remote IR Sensor: This sensor receives infrared (IR) commands

from the remote control. It is important to ensure that it is not blocked.

If covering the sensor is unavoidable, such as when the AVR 3550HD

is placed inside a cabinet, you may use an optional Harman Kardon

HE 1000, or other infrared receiver, connecting it to the Remote IR

Input on the AVR 3550HD’s rear panel. Alternatively, connect the Remote

IR Output of another compatible component to the AVR 3550HD’s

REAR-PANEL CONNECTIONS

Main Power Switch: This mechanical switch turns the power supply

on or off. It is usually left in the up position (On), and cannot be turned

on using the remote control.

AM and FM Antenna Terminals: Connect the included AM

and FM antennas to their respective terminals for radio reception.

XM Antenna Jack: Plug in an XM Connect-and-Play or Mini-Tuner

antenna module here. The XM antenna module is purchased separately,

and should specify that it is for home use with an XM Ready

product.

You will need to subscribe to the XM service, which is available sepa-

rately, and activate the service for your antenna module. (XM service

is not available in Alaska and Hawaii.)

Front, Center and Surround Speaker Outputs: Use two-

conductor speaker wire to connect each set of terminals to the correct

speaker. Remember to observe the correct polarity (positive and negative

connections). Always connect the positive lead to the colored terminal

on the receiver and the red terminal on the speaker. Connect the negative

lead to the black terminal on both the receiver and the speaker. See the

Connections section for more information on connecting your speakers.

Surround Back/Zone 2 Speaker Outputs: These speaker

outputs are used for the surround back channels in a 7.1-channel home

theater, or may be reassigned to a remote room for multizone operation.

When these outputs are reassigned for multizone operation, only a

5.1-channel configuration will be available in the main listening room.

Use the on-screen menu system to configure these channels as desired.

As with the other speaker outputs, remember to observe proper

polarity by connecting the positive and negative output terminals to

the corresponding terminals on each speaker.

Subwoofer Output: If you have a powered subwoofer with a

line-level input, connect it to this jack.

Preamp Outputs: Connect these jacks to an external amplifier if

more power is desired.

The Surround Back/Zone 2 Preamp Outputs may be used with an

external amplifier to power the surround back channels, or to power

the remote zone of a multizone system. Use the on-screen menu

system to configure these channels as desired.

Remote Infrared (IR) Input and Output: When the remote IR

receiver on the front panel is blocked, such as when the AVR is placed

inside a cabinet, connect an optional IR receiver to the Remote IR Input

jack for use with the remote control. The Remote IR Output may be

connected to the Remote IR Input of a compatible product to enable

remote control through the AVR. This is particularly useful in multizone

applications to control a source device from the remote room (when

used with the Zone 2 IR Input). When several source devices are used,

connect them in “daisy chain” fashion.

Zone 2 Infrared (IR) Input: Connect a remote IR receiver located

in the remote zone of a multizone system to this jack to control the AVR

(and any source devices connected to the Remote IR Output) from the

remote zone.

Remote IR Carrier Output: This output is similar in function to

the Remote IR Output, with the difference that this jack outputs the full

infrared signal as received by the AVR’s IR sensor or the Remote IR

Input, while the Remote IR Output jack outputs a “stripped” signal that

has no carrier frequency. The full signal may be required by some

components with IR inputs. It may also be required when you connect

external IR emitters or other devices to the AVR to pass IR signals to

other components.

A-BUS IR Output: This is an additional IR output that may only be

controlled through the A-BUS system. Use it as a dedicated connection

to sources used only with the A-BUS system, or if the other IR outputs

are in use for incompatible applications.

A-BUS Port: Use a Category 5/5e cable to connect this port to

optional A-BUS equipment for multizone operation. When the A-BUS

system is used, it is possible to have a full 7.1-channel system in the

main listening room at the same time the multizone system is in use.

Composite and S-Video 1, 2 and 3 Video Inputs: These

jacks may be used to connect your video-capable source components

(e.g., VCR, DVD player, cable TV box) to the receiver. Use only one type

of video connection for each source. These inputs are assignable, which

means they may be paired with any analog or digital audio inputs. This

will be explained in more detail in subsequent sections of this manual.

NOTE: The Video 2 inputs are associated with a set of outputs.

Consider connecting a video recorder here.

Composite and S-Video 2 Outputs: Connect one of these

analog video outputs to the composite or S-video inputs of a recording

device. A signal is available at these outputs whenever an analog video

source is playing. HDMI and component video signals are not available

for recording.

Composite and S-Video Monitor Outputs: If any of your

sources use composite or S-video connections, connect one or both of

these monitor outputs to the corresponding inputs on your television or

video display. If your video display is equipped with HDMI or component

video inputs, these connections are unnecessary. Connect the HDMI

Monitor Output (if available, otherwise use the Component Video Monitor

Output) to your TV, and the AVR 3550HD will convert the composite

or S-video source signal to the correct format for a single video cable

connection to the TV.

HDMI Inputs and Output: HDMI (High-Definition Multimedia

Interface) is a connection for transmitting digital audio and video signals

between devices. With the AVR 3550HD’s powerful processor, you may

connect up to three HDMI-equipped source devices to the HDMI inputs

using a single-cable connection, while benefiting from superior digital

audio and video performance. If your video display is not HDMI-compatible,

connect the device to one of the analog video inputs, then pair it with

an analog or digital audio input.

If your video display has an HDMI input, make just the HDMI video con-

nection to your display; the AVR 3550HD will automatically transcode

analog video signals to the HDMI format, upscaling to as high as 1080p.

AVR3550HD harman/kardon

REAR-PANEL CONNECTIONS

Analog 1– 5: Connect the left and right analog audio outputs of

a source device to any of these inputs. These inputs are assignable,

which means they may be paired with any video inputs, as explained

in subsequent sections of this manual.

NOTES:

• The Analog 3 through 5 connectors physically line up below

the Video 1 through 3 (composite and S-video) connectors.

For convenience, consider using Analog 3 with Video 1, Analog 4

with Video 2 and Analog 5 with Video 3, if appropriate for

your system.

• The Analog 1 and 2 connectors don’t physically line up with

any analog video inputs. Consider using them for audio-only

devices, such as a CD player or cassette tape deck.

• The Analog 2 and 4 inputs are each associated with a set of

outputs. Consider using the Analog 2 connectors for an audio

recorder, and the Analog 4 connectors for a video recorder

(along with the Video 2 connectors).

• You may optionally connect a source to both an analog and

digital audio input. This is useful for making recordings, for

multizone applications or simply as a backup.

Analog 2 and 4 Outputs: Connect either of these analog audio

outputs to the analog audio inputs of a recording device. A signal is

available at these outputs whenever an analog audio source is playing.

However, the AVR 3550HD does not convert digital audio sources to

analog for recording.

Coaxial 1/2 and Optical 1/ 2/3 Digital Audio Inputs: If a

source has a compatible digital audio output, and if you are not using

an HDMI connection for audio for the device, connect it to one of these

jacks to hear digital audio formats, such as Dolby Digital, DTS and linear

PCM. Use only one type of digital audio connection for each source.

Coaxial Digital Audio Output: If a source is also an audio

recorder, connect a coaxial digital audio output to the recorder’s input

for improved recording quality. Only PCM digital audio signals are

available for recording. The AVR 3550HD will pass signals from the

Optical Digital Audio Inputs to this output.

The Bridge II Input: Connect the included Harman Kardon

docking station to this input for use with most docking

iPod models, 4G and later (not included). Make sure the receiver is

turned off (in Standby mode) when connecting The Bridge II.

6-/8-Channel Inputs: Connect the multichannel analog audio

outputs of a DVD-Audio, SACD

™

, Blu-ray Disc

™

or HD-DVD player

(or any other external decoder) to these jacks to enjoy these formats.

NOTE: When the multichannel player has an onboard digital

decoder, it is not necessary to connect it to the 6-/8-Channel

Analog Audio Inputs. Only a digital audio connection (HDMI,

coaxial or optical) is needed.

Zone 2 Audio Outputs: Connect these jacks to an external amplifier

to power the speakers in the remote zone of a multizone system. When

these jacks are used, it is possible to have a full 7.1-channel system in

the main listening room at the same time the multizone system is in use.

Component Video 1, 2 and 3 Inputs: If a video source (e.g.,

DVD player or HDTV tuner) has analog component video (Y/Pb/Pr)

capability, and if you are not using an HDMI connection for the device,

then connect the component video outputs of the source to one of the

sets of component video inputs. Do not make any other video connec-

tions to that source.

Component Video Monitor Outputs: If you are using one of

the Component Video Inputs and your television or video display is

component-video-capable, and if you are not connecting the HDMI

Output to your display, connect these jacks to the corresponding inputs

on your video display.

NOTES:

• Due to copy-protection restrictions, there is no output at the

Component Video Monitor Outputs for copy-protected sources.

• Composite and S-video signals are upscaled to as high as

1080i and available at these outputs. If your video display’s

best connection is component video, it is the only video

connection required from the AVR to the display.

RS-232 Serial Port: This specialized connector may be used with

your personal computer in case we offer a software upgrade for the

receiver at some time in the future.

RS-232 Mode: Leave this switch popped out in the Operate position

unless the AVR 3550HD is being upgraded.

RS-232 Reset: This switch is only used during a software upgrade.

A standard processor reset is performed by pressing and holding the

front-panel OK Button.

Switched AC Accessory Outlet: You may plug the AC power

cord of one source device into this outlet, and it will turn on whenever

you turn on the receiver. Do not use a source that consumes more than

50 watts of power.

AC Power Input: After you have made all other connections, plug the

AC power cord into this receptacle and into an unswitched wall outlet.

AVR3550HD harman/kardon

MAIN REMOTE CONTROL FUNCTIONS

The AVR 3550HD remote is capable of controlling 7 devices, including

the AVR itself and an iPod docked in the included The Bridge II. During

the installation process, you may program the codes for each of your

source components into the remote. Each time you wish to use the

codes for any component, first press its Selector button. This changes

the button functions to the appropriate codes.

Each Source Selector has been preprogrammed to control certain types

of components, with only the codes specific to each brand and model

changing, depending on which product code is programmed. The AUX

Source Selector may be used for any of five device types: a CD player,

an HDTV set-top box, a PVD recorder used with cable or satellite televi-

sion, a TiVo

set-top box or a VCR. The device mode will depend

on the product code programmed into the AUX Source Selector as

described in the Initial Setup section. CD players use codes beginning

with a 0, 1 or 2; VCRs use codes beginning with a 3 or 4; HDTV

set-top boxes use codes beginning with a 6; PVDs use codes beginning

with a 7 and TiVo set-top boxes use codes beginning with an 8.

The remote automatically switches to the correct device mode, and

it will operate the device as described in the function list in Table A13

in the appendix.

Similarly, the CBL/SAT Source Selector automatically selects cable or

satellite television operation depending on the first digit of the product

code: 0, 1 or 2 for cable and 3 or 4 for satellite boxes.

IMPORTANT NOTE: All of the AVR 3550HD’s audio and video

inputs are independently assignable. As explained in the Initial

Setup section, it is necessary to set up each source, which

includes selecting the inputs to which the device is physically

connected. Any device may be connected to any compatible

input and given any name (e.g., DVD or Game). The Source

Selectors’ device types may be changed. For example, the TV

Source Selector may be reprogrammed to operate a DVD player.

Most of the buttons on the remote have dedicated functions, although the

precise codes transmitted will vary depending on which source device

has been selected for operation. Due to the wide variety of functions

unique to various source devices, we have included only a few of the most-

often used functions on the remote, including alphanumeric keys, transport

controls, television-channel control, menu access and power on and off.

Please refer to the descriptions below for more specific information.

Some buttons are only used to operate the AVR, and their functions are

available at any time, even if the remote has been switched to another

device’s mode: AVR Power On and Off, Audio Effects, Video Modes,

Surround Modes, Volume, Mute and Sleep Settings. Press the AVR

Settings button near the bottom of the remote to return it to AVR mode.

Any given button may have different functions, depending on which

component is being controlled. Some buttons are labeled with these

functions. For example, the Page Up/Down Buttons are labeled for use

as Channel Up/Down Buttons when controlling a television or cable box.

See Table A13 in the appendix for listings of the different functions for

each type of component.

IR Transmitter Lens: As buttons are pressed on the remote,

infrared codes are emitted through this lens. Make sure it is pointing

toward the component being operated.

AVR Power On Button: Press this button to turn on the AVR. The

Master Power Switch on the AVR 3550HD’s rear panel must first have

been switched on.

Device Power Off Button: When the remote has been switched

to a device’s mode by pressing its Source Selector, press this button to

turn off the device.

Device Power On Button: When the remote has been switched

AVR3550HD harman/kardon

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 has established the

CEA

color-coding standard. See Table 1.

Table 1 – Connection Color Guide

Types of Connections

This section will briefly review different types of cables and connections.

Speaker Connections

Speaker cables carry an amplified signal from the receiver’s speaker

terminals to each loudspeaker. Speaker cables contain two wire conduc-

tors, or leads, inside plastic insulation. The two conductors are usually

differentiated in some way, by using different colors, or stripes, or by

adding a ridge to the insulation. Sometimes the wires are different,

colors e.g. copper-colored and 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 (–), referred to as speaker polarity. It’s important

to maintain the proper polarity for all speakers in the system, or perform-

ance 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 3550HD uses binding-post

speaker terminals that can accept banana

plugs or bare-wire cables. Banana plugs

are simply plugged into the hole in the

middle of the terminal cap. See Figure 1.

Figure 1 – Binding-Post Speaker Terminals With Banana Plugs

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. Hand-tighten the cap until the wire is held snugly.

Figure 2 – Binding-Post Speaker Terminals With Bare Wires

Subwoofer

The subwoofer is a specialized type of loudspeaker 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. Usually, 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, but sometimes the subwoofer

is connected to the receiver using the front left and right speaker outputs,

as with passive in-wall subwoofers, and then the front left and right

speakers are connected to terminals on the subwoofer.

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 any other devices.

Although doing so won’t cause any harm, performance will suffer.

Figure 3 – Subwoofer

Connecting Source Devices to the AVR

The AVR 3550HD 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 and the

XM antenna module.

Separate connections are required for the audio and video portions of

the signal, except for digital HDMI connections. 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 required for listening to sources encoded with digital

surround modes, such as Dolby Digital and DTS, or for non-compressed

PCM digital audio. There are three types of digital audio connections:

HDMI, coaxial and optical. Any type of digital audio connection may be

used for each source device, but never more than one for the same

source. However, it’s okay to make both analog and digital audio con-

nections to the same source.

NOTE: Since HDMI signals may carry both audio and video, if

your video display device has an HDMI input, make a single HDMI

connection from your source device (such as a DVD player) to

the AVR. No separate digital audio connection is usually required.

Make sure to turn the volume on your television all the way down.

Digital Audio

The AVR 3550HD is equipped with three HDMI (High-Definition

Multimedia Interface) inputs, and one output. HDMI technology enables

digital audio and video information to be carried using a single cable,

thus delivering the highest quality picture and sound.

There are different HDMI versions, depending on the capability of

the source device and the type of signal it is capable of transmitting.

In addition, receivers and processors such as the AVR 3550HD may

handle the incoming signal in several different ways, depending on their

capability as well. The AVR 3550HD uses HDMI (V.1.3 with Deep Color)

technology and is capable of processing both the audio and video

components of the HDMI data, minimizing the number of cable

connections in your system. The AVR 3550HD implements Deep Color,

which increases by an order of magnitude the shades of color that can

be displayed; and the latest lossless multichannel audio formats, including

Dolby TrueHD and DTS-HD Master Audio.

NOTE: Some DVD-Audio, SACD, Blu-ray Disc and HD-DVD

players, output mulitchannel audio only through the source’s

multichannel analog outputs. For those devices, make a sepa-

rate analog audio connection in addition to the HDMI connec-

tion, which is still used for video and to listen to Dolby Digital,

DTS or PCM materials that may be stored on the disc.

In addition, the AVR 3550HD will convert analog video signals to the

HDMI format, upscaling to high-definition 1080p resolution. You may view

the AVR 3550HD’s own on-screen display menus using the HDMI output.

The physical HDMI connection is simple. The connector is shaped for

easy plug-in (see Figure 4). If your video display has a DVI input and is

HDCP-compliant, you may use an HDMI-to-DVI adapter (not included)

to connect it to the AVR’s HDMI Output, but a separate audio connection

is required. HDMI cable runs are usually limited to about 10 feet,

depending on the type of cable used.

Figure 4 – HDMI Connection

If your video display or source device is not HDMI-capable, use one

of the analog video connections (composite, S- or component video)

and, if available on your source device, either a coaxial or optical digital

audio connection.

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 5.

Figure 5 – 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, while outputs use a

gray shutter. See Figure 6.

Figure 6 – Optical Digital Audio

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 7.

Most sources that have digital audio jacks also have analog audio jacks,

although some older types of sources, such as tape decks, only have

analog jacks. For sources that are capable of both digital and analog

audio, you may make both connections.

The analog audio connection is strongly recommended if you intend

to use the source with the multizone system. It’s required if you will be

using the multizone preamp outputs with an external amplifier to power

your remote speakers, as the AVR 3550HD’s multizone system is not

capable of converting the digital signal to analog format. It’s suggested

that you also use the analog audio connections when using the

Surround Back/Zone 2 speaker outputs, in case another two-channel

digital audio source is in use in the main listening area. The AVR 3550HD

is only capable of processing one PCM source at a time.

You may only record materials from DVDs or other copy-protected

sources, using analog connections. Remember to comply with all copy-

right laws, if you choose to make a copy for your own personal use.

Figure 7 – Analog Audio

Multichannel analog connections are used with some high-definition

sources where the copy-protected digital content is decoded inside the

source. These types of connections are usually used with DVD-Audio,

SACD, Blu-ray Disc, HD-DVD and other multichannel players. See

Figure 8. However, the multichannel analog audio connection is not

required for DVD-Audio players compliant with HDMI version 1.1 or

better, or HD-DVD and Blu-ray Disc players that decode the digital audio

internally and output linear PCM signals in digital format. Consult the

owner’s guide for your disc player for more information.

Figure 8 – Multichannel Analog Audio

Harman Kardon receivers also include a proprietary, dedicated audio

connection called The Bridge II docking station for iPod. If you own a

docking iPod (most models, 4G or later), connect The Bridge II (included)

to The Bridge II port on the receiver. See Figure 9. Dock your iPod

(not included) in The Bridge II, and you may listen to your audio materials

through your high-performance audio system. You may view still images

or video materials stored on a photo- or video-capable iPod that

supports video browsing. You may even use the AVR 3550HD remote

to control the iPod with navigation messages displayed on the front panel

and on a video display connected to the AVR. The Bridge II outputs analog

audio to the AVR 3550HD, and it is available to the multiroom system.

Figure 9 – The Bridge II port

Video Connections

Although some sources only produce an audio signal (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, make one type of video connection

for each of these sources (only one at a time for any source).

Digital Video

If you have already connected a source device to one of the HDMI

inputs as explained in the Digital Audio Connections section, you have

automatically made a video connection at the same time, as the HDMI

signal includes both digital audio and video components.

If the source device is not capable of transmitting its digital audio signal

through the HDMI connection, use one of the coaxial or optical digital

audio inputs for the source.

If a multichannel analog audio connection is required for certain lossless

formats (e.g., DVD-Audio, SACD, Blu-ray Disc or HD-DVD), you may

make both audio connections. To listen to the multichannel disc, set the

Audio Auto Polling setting to the 6/8CH inputs, and the AVR will automati-

cally select it when no digital signal is output by the player.

Analog Video

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 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, or vice versa.

Both the chrominance (color) and luminance (intensity) components of

the video signal are transmitted using a single cable. See Figure 10.

Figure 10 – 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 11.

Figure 11 – S-Video

Component video separates the video signal into three components –

one luminance (“Y”) and two sub-sampled color signals (“Pb” and “Pr”) –

that are transmitted using three separate cables. The “Y” cable is color-

coded green, the “Pb” cable is colored blue and the “Pr” cable is

colored red. See Figure 12.

Figure 12 – Component Video

If it’s available on your video display, an HDMI connection is recom-

mended as the best quality connection, followed by component video,

S-video and then composite video.

NOTES:

• Copy-protected sources are not available at the Component

Video Monitor Outputs.

• Standard and high-definition analog video signals are upscaled

to 1080i resolution for the Component Video Monitor Outputs.

For improved video performance, consider upgrading to an

HDMI-capable video display with 1080p resolution.

Antennas

The AVR 3550HD uses separate terminals for the included FM and AM

antennas that provide proper reception for the tuner.

The AM loop antenna needs to be assembled. Connect the two leads

to the spring terminals on the receiver. As AM antenna leads have no

polarity, it doesn’t matter which of the two terminals is used for either

lead. See Figure 14.

Figure 14 – AM Antenna

To enjoy XM satellite radio, purchase an XM antenna module designed

for use with XM Ready devices and a subscription to the XM service.

We recommend the XM Mini Tuner and Home Dock Bundle, available

at www.xmradio.com. The older Connect-and-Play module is also

compatible with the AVR 3550HD, but it may no longer be available

in your area.

An XM Ready-compatible module uses the special connector on the

AVR 3550HD’s rear panel that allows you to use the AVR’s tuner,

including its 40 preset station locations and remote control. Although

you may use a module with standard audio connections, which may

be indicated for “car and home use,” you will not be able to enjoy the

AVR 3550HD’s ease of control.

RS-232 Serial Port

The RS-232 serial port on the AVR 3550HD is used only for software

upgrades. If we release an upgrade for the receiver’s operating system

at some time in the future, it may be downloaded to the AVR using this

port. Complete instructions will be provided at that time.

CONNECTIONS

AVR3550HD harman/kardon

OPERATION

Now that you have installed your system components and completed

a basic configuration of your receiver, you are ready to begin enjoying

your home theater system.

Turning On the AVR 3550HD

Flip the Main Power Switch on the rear panel up to the “ On” position. The

Power Indicator on the front panel should light up in amber. This indicates

that the AVR is in Standby mode and is ready to be turned on. Normally,

you may leave the Main Power Switch on, even when the receiver is not

being used. See Figure 46.

There are several ways in which the AVR 3550HD may be turned on:

a) Press the Standby/On Switch on the front panel. See Figure 46.

b) Using the remote, press the AVR Power On Button or any of the

Source Selectors. See Figure 47.

To turn the receiver off, press either the Standby/On Switch on the front

panel, or press the AVR Power Off Button on the remote. Unless the

receiver will not be used for an extended period of time (for example,

when are on vacation), it is not necessary to turn off the Main Power

Switch. When the Main Power Switch is turned off, any settings you

have programmed, including system configuration and preset radio

stations, will be preserved for up to four weeks.

IMPORTANT NOTE: If the PROTECT message ever appears

in the Message Display, turn off the AVR and unplug it. Check

all speaker wires for a possible short. If none is found, bring

the unit to an authorized Harman Kardon service center for

inspection and repair before using it again.

Volume Control

The volume may be adjusted either by turning the knob on the front

panel (clockwise to increase volume or counterclockwise to decrease

volume), or by pressing the Volume Control on the remote. See Figure 57.

The volume is displayed as a negative number of decibels (dB) below

the 0dB reference point.

Unlike the volume controls on some other products, 0dB is the maximum

volume for the AVR 3550HD. Although it’s physically possible to turn the

volume to a higher level, doing so may damage your hearing and your

speakers. For certain more dynamic audio materials, even 0dB may be

too high, allowing for damage to equipment. We urge caution with

regard to volume levels.

You may change the volume level display from the default decibel scale

to a 0-to-100 scale by adjusting the Volume Units setting in the System

Settings menu, as described on page 55.

Figure 57 – Volume Controls

Mute Function

To temporarily mute all speakers and the headphones, press the Mute

Button on the remote. See Figure 57. Any recording in progress will

not be affected. The MUTE message will appear in the display as a

or adjust the volume. Turning off the AVR will also end muting.

Sleep Timer

You may program the AVR to play for up to 90 minutes and then turn

off automatically using the sleep timer.

Press the Sleep Settings Button on the remote, and the time until

turn-off will be displayed. See Figure 58. Each additional press of the

Sleep Button will increase the time until turn-off by 10 minutes, up

to a maximum of 90 minutes, then the SLEEP OFF setting appears,

which disables the sleep timer.

Figure 58 – Sleep Settings Button

When the sleep timer has been set, the front-panel display will automati-

cally dim to half-brightness. If you press any button on the remote or

front panel, the display will return to full-brightness. The display will dim

again several seconds after your last command.

If you press the Sleep Button after the timer has been set, the remaining

time until turn-off will be displayed. You may press the Sleep Button to

change the time until turn-off.

Audio Effects

Depending on your preferences or the specific characteristics of your

listening room, you may wish to adjust some of the audio settings, such

as tone controls, to improve performance. Access these settings from

the Audio Effects submenu, as described in the Advanced Functions

section.

It is not necessary to adjust the Audio Effects settings to enjoy your

new AVR. We recommend leaving the settings at their default values

until you are more familiar with your system.

Video Modes

The settings in the Video Modes menu are used to fine-tune the

picture if necessary after making all adjustments on the video display.

It is recommended that you leave the settings at their defaults. See the

Advanced Functions section for detailed information.

Headphones

Plug the 1/4" plug on a pair of headphones into the headphone

jack on the front of the receiver for private listening. See Figure 59.

Any other settings you adjusted in the Setup Source menu will also be

selected. You may view these settings in the Source Info menu at any

time by pressing the Info Settings Button.

VIDEO TROUBLESHOOTING TIPS:

If a video source is playing and there is no picture:

• Check that you have selected the source to which the

video input was assigned.

• Check the wires for a loose or incorrect connection.

• Check that you have selected the correct video input on

the display device (TV).

• Try pressing the Resolution Button on the front panel repeat-

edly until the correct video output resolution is selected and

a picture appears. You will be prompted to accept or cancel

the resolution change, as the CANCEL message will appear

on the front panel. Press the

option, and then press the OK Button to complete the change

to the output resolution.

Additional Tips for Systems Using HDMI:

• Turn off all devices (including the TV, AVR and any source

components).

• Unplug the HDMI cables starting with the cable between the

TV and AVR, and continuing with the cables between the AVR

and each source device.

• Carefully reconnect the cables from the source devices to

the AVR, and connect the cable from the AVR to the TV last.

• Turn on the devices in this order: TV, then AVR, then source

devices.

Using the Tuner

To select the AVR 3550HD’s built-in tuner:

1. Press the Source List Button on the front panel repeatedly until the

desired tuner band is selected, or use the

⁄

through the source list.

2. Press the Radio Source Selector on the remote. Press this button

again to switch bands (AM, FM or XM).

A screen similar to the one shown in Figure 61 will appear, with the

band indicated in the middle of the screen. (The XM band uses a slightly

different screen.)

Figure 61 – FM Radio

Use the

⁄

Buttons to tune a station (or channel for XM Radio).

The frequencies will be displayed in the front panel and graphically on

screen.

The AVR defaults to automatic tuning, meaning each press of the

⁄

Buttons scans through all frequencies until a station with accept-

able signal strength is found. To switch to manual tuning, in which each

press of the

⁄

Buttons steps through a single frequency increment

(0.1MHz for FM, or 10kHz for AM), press the Menu Button. The Radio

Modes line will be highlighted, and each press of the OK Button toggles

between automatic and manual tuning modes.

When an FM station has been tuned, toggling the radio mode switches

between stereo and monaural play, which may improve reception of

weaker stations.

A total of 30 stations (AM and FM together) may be stored as presets.

When the desired station has been tuned, press the OK Button, and two

dashes will flash in the front-panel display. Use the Alphanumeric Keys

XM Radio Operation

XM Radio is a satellite-delivered service that offers hundreds of program

channels, as well as local traffic and weather information for select cities.

The AVR 3550HD is an XM Ready device, which means that it is able to

receive the XM service when a user-supplied XM antenna module is

connected and the service activated.

Select an antenna module designated for XM Ready audio components.

An XM Ready-compatible module uses the special connector on the

AVR 3550HD’s rear panel that allows you to use the AVR’s tuner,

including its 40 preset station locations and remote control. Although

you may use a module with standard audio connections, which may be

indicated for “car and home use,” you will not be able to enjoy the AVR

3550HD’s ease of control.

use is also compatible, but has been discontinued and may no longer

be available. Additional modules may become available in the future.

Modules produced for automotive, or “mobile,” use are not compatible

with the AVR 3550HD, although if they have standard analog or digital

audio outputs, they may be connected to a compatible input and oper-

ated using their own controls.

NOTE: To listen to XM Radio using the AVR 3550HD, you will

need to purchase an XM antenna module and subscription, and

activate your module. XM service is not available in Alaska or

Hawaii. Visit the XM Radio Web site at www.xmradio.com for

more information.

Plug the module into the XM Antenna Jack on the rear of the AVR 3550HD.

Place the antenna module so that it has a clear view through a south-

facing window in order to obtain reception from the XM satellite.

Select XM Radio as the source in one of these ways:

1. Press the Source List Button on the front panel repeatedly until

XM Radio is selected, or use the

⁄

Buttons to scroll through

the source list.

2. Press the Radio Source Selector on the remote repeatedly until

XM Radio is selected..

You should be able to tune in Channel 1, the Preview Channel, to

confirm that your equipment is ready for activation. There are four

ways to tune an XM Radio channel:

1. Press the Menu Button to select a search mode: preset, category,

all channels (the default) or direct entry.

2. Use the

⁄

Buttons to scan through the channel numbers in

the default All Channel search mode. If you press the OK Button first,

pressing the

⁄

Buttons will scan through any preset positions

you have programmed (Preset search mode).

3. In Category search mode, use the

‹

›

Buttons to jump to the

next category, and then use the

⁄

Buttons to scan through

the channel numbers within the category.

4. After you have programmed presets, directly enter the preset number

(1 through 40) using the Alphanumeric Keys. For single-digit positions,

enter a “0” before the number. Select Direct Entry search mode, and

use the Alphanumeric Keys to select a channel directly.

When you are able to hear Channel 1, you are ready to activate your

module. If you don’t hear Channel 1, make sure the module’s plug is

firmly seated in the XM Antenna jack, and that the module is near a

south-facing window. Try unfolding the module and rotating it to obtain

reception. You may need to purchase an extension cable, available on

the XM Radio site, to ensure that the module is near the window.

Tune to Channel 0 for a display of your antenna module’s Radio ID

number, required for activation.

The current channel number and preset location will appear in the upper

line of the Message Display, and the search mode (all channels, category)

will appear in the lower line. Three signal-strength bars will appear to

the right of the channel number and preset location to indicate signal

strength. The song title, artist and channel category, along with the

channel number and preset position (if programmed), will all appear

on screen when a video display is in use.

For traffic and weather channels, the current city’s name will appear

instead of the channel name, and the local weather and temperature

will be displayed on screen.

To store a channel in one of the 40 preset locations:

1. Tune to the desired channel and press the OK Button. The lowest

available preset number will flash on screen and in the front-panel

Message Display.

2. Use the Alphanumeric Keys to enter the numbered preset location

you wish to store the channel in, or do nothing if the current preset

location is acceptable.

3. Press the OK Button to store the new preset.

Recording

Two-channel analog and digital audio signals, as well as composite

and S-video signals, are normally available at the appropriate recording

outputs. Thus, to make a recording, you need only make sure to con-

nect your audio or video recorder to the appropriate output jacks, as

described in the Installation section, insert blank media and make sure

the recorder is turned on and recording while the source is playing.

restrictions on any material you record. Unauthorized duplica-

tion of copyrighted materials is prohibited by federal law.

Using Docking Station

The Bridge II is an included dock that is compatible with most docking

iPod models, 4G and later (not included). When The Bridge II is con-

nected to its proprietary input on the AVR 3550HD and the iPod is

docked, you may play the audio, video and still-image materials on your

iPod through your high-quality audio/video system, operate the iPod

using the AVR remote or the AVR’s front-panel controls, view navigation

messages on the AVR’s front panel or a connected video display,

and charge the iPod.

Either press the front-panel Source Selector repeatedly until the message

“The Bridge is CONNECTED” appears in the front panel, or press The

Bridge Source Selector on the remote. If the AVR has difficulty detecting

that the iPod is connected and you have determined that The Bridge II

is properly plugged into the AVR, turn off the AVR, remove the iPod from

The Bridge II and reset the iPod as described in its user guide. When

the iPod returns to its main menu, redock it and turn on the AVR.

When The Bridge II is connected, the screen shown in Figure 62

will appear on a video display connected to the AVR.

iPod. The system will switch to iPod Manual Mode, and control will shift

to the iPod. Use the screen and controls on the iPod, although the AVR

remote may be used for scrolling and selecting.

If the iPod supports video browsing, visual materials may be displayed

on a video monitor connected to the AVR as follows: Select the desired

photo and press the Play Button

on the iPod itself

to begin slideshow

playback. If you use the AVR’s remote, press the OK Button

three

times.

Videos: This line may appear, but cannot be selected. If the iPod sup-

ports video browsing, you may view videos on an external monitor by

following this procedure: Select the Photos line in the on-screen menu

so that the system switches to iPod Manual Mode. Use either the controls

on the iPod or the AVR remote to select a video for playback, making

sure the TV Out setting on the iPod is turned on.

NOTES ON VIDEO PLAYBACK:

• As of this writing, video browsing is only supported on the

iPod 5G, iPod classic and iPod nano 3G. For other iPod models,

it is not possible to view photos or videos on an external

monitor while using The Bridge II. However, you may purchase

a compatible A/V cable from Apple Inc. that has a dock con-

nector on one end and conventional audio and video plugs

on the other end. The audio/video plugs may be connected

to any available analog inputs on the AVR, as you would for

any other source device.

• Before attempting to view photos or videos stored on your

iPod, check the Video Settings menu on the iPod and make

sure that the TV Out setting is set to On. The TV Signal setting

should be NTSC to match the capabilities of your video

display. Set Widescreen to On or Off, depending on the

aspect ratio of your video display. If your selection was playing

and paused, the iPod requires you to reselect the video for

the new TV Out setting to take effect.

• In iPod Manual Mode, the iPod menus will only be visible

on the iPod screen itself. You may operate the iPod using the

AVR remote, as long as it is in The Bridge device mode.

• The MP4 and H.264 video formats often used for videos to

be played on the iPod are intended for optimal performance

on the small screen of the iPod. Playback on larger displays

may have different results.

After selecting photo or video viewing, the AVR may remain in iPod

Manual Mode, even after undocking the iPod or switching to another

source input and back again. To return to normal operation, with the

AVR remote in The Bridge mode, press and hold the Menu Button.

Random: Select this setting for random playback, also known as

“Shuffle Mode”. Each press of the OK Button switches the setting:

shuffle by Song, shuffle by Album, or Off to end random playback.

Repeat: Select this setting to repeat a track or all tracks in the current

album or play list. Each press of the OK Button switches the setting:

repeat Off, repeat One or repeat All.

While a selection is playing, the song title, artist and album name, if

available on the iPod, will appear in the upper line in the front-panel

Message Display. The lower line will display the elapsed time of the track

on the left, the play mode icon, and the time remaining on the right.

In addition, if a video monitor is connected to the AVR 3550HD and the

system is not in iPod Manual Mode, it will display information about the

status of the iPod and the track, including the play mode icon, the song

title, artist and album. A graphic bar indicates the current play position

within the track. If random or repeat play has been programmed, an icon

will appear in the upper right corner.

After a period of time, the screen may disappear from view. The length

of time is set using the Setup and Slide-In Menus setting in the System

Settings menu (described in the Advanced Functions section). You

may restore the Now Playing screen to view by pressing either of the

‹

›

Buttons.

NOTE: It is strongly recommended that you use a screen saver

built into your video display to avoid possible damage from

“burn-in” that may occur with plasma and many CRT displays

when a still image, such as a menu screen, remains on display

for an extended period of time.

Selecting a Surround Mode

Surround mode selection can be as simple or sophisticated as your

individual system and tastes. Feel free to experiment, and you may

find a few favorites for certain sources or program types. More detailed

information on surround modes may be found in the Advanced

Functions section.

To select a surround mode, press the Surround Modes Button

(front panel or remote) repeatedly until the desired option appears:

SURR: AUTO SELECT, SURR: VIRTUAL, SURR: STEREO, SURR: MOVIE,

SURR: MUSIC or SURR: GAME. The option will be displayed in the

Lower Line of the Message Display, and the Surround Modes menu

will appear on screen (see Figure 63).

Figure 63 – Surround Modes Menu

Auto Select: For digital programs, such as movies recorded with

a Dolby Digital soundtrack, the AVR will automatically use the native

surround format. For 2-channel analog and PCM programs, the AVR

is programmed to default to Logic 7 Movie mode.

Virtual Surround: When only two main speakers are present in the

system, Dolby Virtual Surround may be used to create an enhanced

soundfield that virtualizes the missing speakers. Select between Wide

and Reference modes, depending on your preferences.

Stereo: When 2-channel playback is desired, select the number of

speakers used for playback:

• 2 CH STEREO for playback through only two speakers. As described

on page 45, you may select Analog Bypass mode for a pure analog

signal when analog audio inputs are in use. Simply set the Tone

Control setting in the Audio Effects submenu to Off, and the AVR

does the rest.

• 5 CH STEREO for playing the left-channel signal through the front

and surround left speakers, the right-channel signal through the right

speakers and a summed mono signal through the center speaker.

• 7 CH STEREO follows the same scheme as 5 CH STEREO, but adds

the surround back speakers to the mix. This mode is only available

when the surround back speakers are present and have not been

reassigned to multizone operation. See the Initial Setup section for

more information.

Movie: Select an analog surround mode for movie playback: Logic 7

Movie, DTS Neo:6 Cinema or Dolby Pro Logic II (IIx when seven main

speakers are present). The desired mode may also be selected when

a compatible digital surround mode is received.

TROUBLESHOOTING GUIDE

AVR3550HD harman/kardon

Learning

If you have programmed a product’s codes into the remote and find that

some functions are missing, the AVR 3550HD remote may “learn” indi-

vidual codes if you have the product’s original remote. See page 31 for

instructions on learning remote codes.

Resetting the Remote

To reset the remote to its factory defaults, simultaneously press and

hold the TV Source Selector and the “0” Alphanumeric Key. When the

TV Button re-lights, enter the code “333”. When the TV Button goes

out, and all of the Source Selectors flash, the remote will have been

fully reset.

Processor Reset

There may be instances when you wish to fully reset the AVR 3550HD to

its factory defaults, or the unit may behave erratically after a power surge.

To correct erratic behavior, first try turning the Master Power Switch off

and unplugging the AC power cord for at least three minutes. Plug the

cord back in and turn the receiver back on. If this doesn’t help, try a

system reset.

NOTES:

• A system reset erases all user configurations, including video

resolution, speaker and level settings, and tuner presets. After

a reset, you will need to reenter all of these settings.

• The RS-232 Reset Button on the rear panel of the AVR

3550HD does not perform a system reset. DO NOT press

the RS-232 Reset Button.

To reset the AVR 3550HD, place the receiver in Standby mode (press

the front-panel Standby/On Switch so that the Power Indicator turns

amber). Then press and hold the front-panel OK Button for at least five

seconds until the RESET message appears in the display.

Follow the directions in the note on page 34 to restore the picture

if necessary.

If the receiver still does not function correctly after a processor reset,

contact an authorized Harman Kardon service center for assistance.

Authorized service centers may be located by visiting the Web site

at www.harmankardon.com.

Memory

If the AVR 3550HD is unplugged or experiences a power outage, it will

retain user settings for up to four weeks.
