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. CAUTION : 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.
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.

REAR - PANEL CONNECTIONS
6-/8-Channel Inputs: Connect the multichannel analog audio outputs of a non-HDMI player (DVD-Audio, SACDTM, Blu-ray DiscTM or HD-DVD, or any other external decoder) to these jacks. Coaxial 1/2/3 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. IR receiver to the Remote IR Input jack. The Remote IR Output may be connected to the Remote IR Input of a compatible product to enable remote control through the AVR.
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.
Coaxial and Optical Digital Audio Outputs: If
a source is also an audio recorder, connect one of the Digital Audio Outputs to the recorder's matching input for improved recording quality. Only PCM digital audio signals are available for recording. Both coaxial and optical digital audio signals are available at either Digital Audio Output.
XM Antenna Jack: Plug in an XM Connect-and-Play or
Mini-Tuner antenna module here.
HDMI Inputs and Output: HDMI (High-Definition Multimedia Interface) is a connection for transmitting digital audio and video signals between devices. Connect up to four HDMIequipped source devices to the HDMI inputs using a single-cable connection. When you connect the HDMI Output to your video display, the AVR 7550HD will automatically transcode analog video signals to the HDMI format, upscaling to as high as 1080p.
NOTES: When connecting a DVI-equipped display to one of the HDMI Outputs: · Use an HDMI-to-DVI adapter. · Make sure the display is HDCP-compliant. If it isn't, do not connect it to an HDMI Output; use an analog video connection instead. · Always make a separate audio connection.
Network Jack: Plug in an RJ-45-compatible cable that connects to a personal computer (PC), router or Internet access. When connected to a PC, the AVR 7550HD is capable of playing audio and JPEG files stored on the PC. When connected to the Internet, the AVR 7550HD may be used to enjoy Internet Radio. See pages 36 and 37 for more information.
RS-232 Serial Port: This bi-directional port may be used to control the AVR 7550HD using an RS-232 serial control link to a compatible computer or programmable remote control system. Due to the complexity of programming RS-232 commands, connections and programming for control purposes should be performed by a qualified custom installer. Trigger 1 and 2 Outputs: Connect these control jacks to the trigger input jack of an external component, such as an audio power amplifier, that you want to power on any time the AVR 7550HD is turned on, without using the AVR's Switched Accessory Outlet for power. When this connection is used, the AVR 7550HD will automatically send a low-voltage signal to the connected device that triggers it to turn on when the AVR 7550HD is on, and off when the AVR 7550HD is placed in the Standby Mode. The connected component must respond to 6-volt presence as the control signal. The Trigger 2 Output may be programmed to transmit its signal only when certain of the AVR's source inputs are selected. For example, to lower a screen when watching a DVD movie, but not while listening to the tuner, connect the Trigger 2 Output to the screen and program it to be on when the DVD source is selected, but off when the AM, FM or XM bands are in use. See the Initial Setup section for more information on programming this setting in the Info Settings menus for each source. 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 Infrared (IR) Input and Output: When the
remote IR receiver on the front panel is blocked, connect an optional 9
Analog 1 5 Inputs: Connect the left and right analog
audio outputs of a source device to any of these inputs. These inputs may be paired with any video inputs. NOTES: · The Analog 3 and 4 inputs are each associated with a set of outputs. Consider using these connectors for an audio or video recorder. · 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 3 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. Zone 2 Audio Outputs: Connect these jacks to an external amplifier to power the speakers in the remote zone of a multizone system. Subwoofer 1 and 2 Outputs: If you have a powered subwoofer with a line-level input, connect it to the Subwoofer 1 Output. For improved performance, connect a second powered subwoofer to the Subwoofer 2 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). Turn the receiver off (Standby mode) when connecting The Bridge II.

REAR - PANEL CONNECTIONS
Fan Vents: This area contains vents used by the AVR 7550HD's
fan to cool the system. Maintain a clearance of at least 3 inches from the nearest surface to avoid overheating the unit. It is normal for the fan to remain off at most normal volume levels. An automatic temperature sensor turns the fan on only when it is needed. IMPORTANT NOTE: Never block the fan vents, as doing so could allow the AVR to overheat to dangerous levels.
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 remote zone of a multizone system. 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 7.2-channel system in the main listening room at the same time the multizone system is in use.
Zone 2 Video Output: Connect this composite video jack to a video display located in the remote zone of a multizone system. When the multizone system is in use, viewers in the remote zone will be able to see the AVR's on-screen text menus and any available source video, as long as the source is connected to a Composite Video Input, and that input is specified for that source in the Zone 2 Video setting of the Info Settings menu.
Composite and S-Video 1, 2 and 3 Video Inputs: Use these jacks 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.
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).
Surround Back/Zone 2 Speaker Outputs: These
speaker outputs are used for the surround back channels in a 7.2-channel home theater, or may be reassigned to a remote room for multizone operation.
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.
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.
AC Power Input: After you have made all other connections,
plug the AC power cord into this receptacle and into an unswitched wall outlet.
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 video display. If your video display is equipped with HDMI or component video inputs, these connections are unnecessary, as the AVR 7550HD will convert the composite or S-video source signal to the correct format for a single video-cable connection to the TV.
Component Video 1, 2 and 3 Inputs: If a video
source has analog component video (Y/Pb/Pr) capability, and if you are not using an HDMI connection, connect the component video outputs of the source to one of the sets of component video inputs. Do not make any other video connections 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 (but does not have HDMI), connect these jacks to the 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.
AM and FM Antenna Terminals: Connect the included
AM and FM antennas to their respective terminals for radio reception.

MAIN REMOTE CONTROL FUNCTIONS
The AVR 7550HD remote is capable of controlling up to 14 devices, including the AVR itself, an iPod docked in the included The Bridge II, a USB device and a Network device (see page 37 for details). During the installation process, you may program the codes for your source components into the remote. To operate a component, press its Selector button to change the device mode. The device mode will appear on the top line of the remote's LCD Display. NOTE: Four of the sources do not have dedicated Source Selectors: Source A, Source B, Source C and Source D. To select one of these sources, first press the AVR Settings Button, then press the appropriate Soft Key: Red for Source A, Green for Source B, Yellow for Source C and Blue for Source D. These sources may also be selected using the AVR Settings menu. 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 and Cable/SAT Source Selectors may be used for multiple device types. All of the external Source Selectors may be reassigned to other device types (see Initial Setup section). AUX Source Selector: CD player, VCR, HDTV set-top box, PVD or TiVo® set-top box.
LCD Display: This two-line text display informs you of the current device mode (i.e., which source is active) on the upper line. When you press a key, the command will appear briefly on the lower line. Source Selectors: Press one of these buttons to select a source device, e.g., DVD, CD, cable TV, satellite or HDTV tuner. This will also turn on the receiver and switch the remote's device mode to operate the source. The first press of the Radio Selector switches the AVR to the last-used tuner band (AM, FM or XM). Each successive press changes the band. Similarly, the Network Button toggles between the Network and Internet Radio sources. Audio Effects: Press to directly access the Audio Effects
submenu, which allows adjustment of the AVR's tone and other audio controls. See the Initial Setup section for more information.
Video Modes: Press for direct access to the Video Modes submenu, which contains picture settings to be used after you have adjusted the picture settings on the video display or TV. See the Advanced Functions section for more information. Surround Modes: Press to directly access the Surround Modes submenu. Scroll to the lines for the Surround Mode categories: Auto Select, Virtual Surround, Stereo, Movie, Music or Video Game. The surround mode will change when the menu line is highlighted. To change the surround mode for the selected category, press the OK Button when the menu line for the Surround Mode category matching the audio program is highlighted, and select one of the available surround mode options using the 1/5 Buttons. Press the OK Button. See the Advanced Functions section for more information on surround modes. Alphanumeric Keys: Use these buttons to enter numbers for radio station frequencies or channels, or to select station presets. Last Channel: When controlling the tuner; a cable, satellite

Cable/SAT Source Selector: Cable set-top box or satellite set-top box. IMPORTANT NOTE: All of the AVR 7550HD's audio and video inputs are independently assignable. Select the inputs to which the device is physically connected during Initial Setup. Any device may be connected to any compatible input and given any name (e.g., DVD or Game). Most of the buttons on the remote have dedicated functions, although the precise codes transmitted vary, depending on the device mode. Due to the wide variety of functions for various source devices, only a few of the most-often used functions on the remote have been included: alphanumeric keys, transport controls, televisionchannel control, menu access, and power on and off. Buttons dedicated to the AVR are available at any time, even in another device 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. A button's function depends on which component is being controlled.

CONNECTIONS
There are different types of audio and video connections used to connect the receiver, the speakers, the video display, and the source devices. The Consumer Electronics Association has established the CEA® color-coding standard. See Table 1. Table 1 Connection Color Guide
Audio Connections
Front (FL/FR) Center (C) Surround (SL/SR) Surround Back (SBL/SBR) Subwoofer (SUB) Left White Green Blue Brown Purple Gray Tan Right Red
Subwoofer
The subwoofer is dedicated to the low frequencies (bass), which require more power. To obtain the best results, most speaker manufacturers offer powered subwoofers that contain their own amplifier. 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. The AVR 7550HD offers the option of connecting two subwoofers to independent outputs, which enables the EzSet/EQ II process to configure each subwoofer precisely to account for its unique characteristics and placement within the room. Although the purple subwoofer outputs look similar to full-range analog audio jacks, they are filtered to allow only the low frequencies to pass. Don't connect these outputs to any other devices.

Speaker Connections
Speaker cables carry an amplified signal from the receiver's speaker terminals to each loudspeaker. They contain two wire conductors, or leads, inside plastic insulation, that are differentiated in some way, such as with colors or stripes. The differentiation preserves polarity, without which low-frequency performance can suffer. Each speaker is connected to the receiver's speaker-output terminals using two wires, one positive (+) and one negative (). Always connect the positive terminal on the speaker, which is usually colored red, to the positive terminal on the receiver, which is colored as indicated in the Connection Color Guide above (Table 1). The negative terminals are both black. The AVR 7550HD uses binding-post speaker terminals that can accept banana plugs or bare-wire cables. + Banana plugs are inserted into the hole in the middle of the terminal cap. See Figure 1.
Figure 1 Binding-Post Speaker Terminals With Banana Plugs
CONNECTING SOURCE DEVICES TO THE AVR
Audio and video signals originate in "source devices," including your Blu-ray Disc or DVD player, CD player, DVR (digital video recorder) or other recorder, tape deck, game console, cable or satellite television box, MP3 player, USB drive or network device. The AVR's tuner 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 the capabilities of the source device and video display.
Audio Connections
There are two types of 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 noncompressed PCM digital audio. There are three types of digital audio connections: HDMI, coaxial and optical. Do not use more than one type of digital audio connection for each source device. However, it's okay to make both analog and digital audio connections to the same source. NOTE: HDMI signals may carry both audio and video. If your video display device has an HDMI input, make a single HDMI connection from each source device to the AVR. Usually, a separate digital audio connection is not required. Turn the volume on your television all the way down. Digital Audio The AVR 7550HD is equipped with four HDMI (High-Definition Multimedia Interface) inputs, and one output. HDMI technology enables digital audio and video information to be carried using a single cable, delivering the highest quality picture and sound. The AVR 7550HD uses HDMI (V.1.3a with Deep Color) technology and is capable of processing both the audio and video components
Bare wire cables are installed as follows (see Figure 2): 1. Unscrew the terminal cap until the pass-through hole is revealed. 2. Insert the bare end of the wire into the hole. 3. Hand-tighten the cap until the wire is held snugly.

of the HDMI data, minimizing the number of cable connections in your system. The AVR 7550HD 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 only output multichannel audio through their multichannel analog outputs. Make a separate analog audio connection in addition to the HDMI connection, which is still used for video and to listen to Dolby Digital, DTS or PCM materials that may be stored on the disc. The AVR 7550HD converts analog video signals to the HDMI format, including its on-screen menus, upscaling to high-definition 1080p resolution. The HDMI connector is shaped for easy plug-in (see Figure 4). If your video display has a DVI input and is HDCP-compliant, use an HDMI-to-DVI adapter (not included). A separate audio connection is required. HDMI cable runs are limited to about 10 feet. You may only record materials from DVDs or other copy-protected sources using analog connections. Remember to comply with all copyright laws, if you choose to make a copy for your own personal use.

Figure 7 Analog Audio
Multichannel analog connections are used with high-definition sources that decode the copy-protected digital content, such as some DVD-Audio, SACD, Blu-ray Disc and HD-DVD players. See Figure 8. The multichannel analog audio connection is not required for players compliant with HDMI version 1.1 or better, or that output linear PCM signals via an HDMI connection. Consult the owner's guide for your disc player for more information.

If your video display or source device is not HDMI-capable, use one of the analog video connections (composite, S- or component video) and a separate audio connection. Coaxial digital audio jacks are usually color-coded in orange. Although they look similar to analog jacks, you should not connect coaxial digital audio outputs to analog inputs or vice versa. See Figure 5.

The AVR 7550HD also includes a proprietary, dedicated audio connection for 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 videocapable iPod that supports video browsing. Use the AVR 7550HD 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 7550HD, and is available to the multiroom system.
THE BRIDGE
Figure 9 The Bridge II port
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. See Figure 7. For sources that are capable of both digital and analog audio, you may make both connections. The analog audio connection is required for multizone operation, as the AVR 7550HD's multizone system is not capable of converting a digital signal to analog format. Use the analog audio connections even with the Surround Back/Zone 2 speaker outputs, in case another 2-channel digital audio source is in use in the main listening area. The AVR 7550HD is only capable of processing one PCM source at a time. 15
Video Connections
Many sources output both audio and video signals (e.g., Blu-ray Disc or 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, you have automatically made a video connection, as the HDMI signal includes both digital audio and video components. Analog Video There are three types of analog video connections: composite video, S-video and component video.
AVR 7550HD
harman/kardon
CONNECTIONS
Composite video is the basic connection most commonly available. The jack is usually color-coded yellow, and looks like an analog audio jack. 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.
Composite video cable Figure 10 Composite Video
The AM loop antenna needs to be assembled. Connect the two leads to the spring terminals on the receiver. The AM antenna leads have no polarity, and you may connect them to either terminal. See Figure 14.
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. Align the plug correctly when you insert it into the jack. See Figure 11.
S-video cable Figure 11 S-Video
Figure 14 AM Antenna
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. See Figure 12.
Y Green Component video cable Pb Blue Pr Red Figure 12 Component Video
To enjoy XM satellite radio, purchase an XM Ready antenna module and a subscription to the XM service. The XM Mini Tuner and Home Dock Bundle, available at www.xmradio.com, is recommended. The older Connect-and-Play module is also compatible with the AVR 7550HD, but it may no longer be available. Although you may use a module with standard audio connections, labeled for "car and home use," you will not be able to enjoy the AVR 7550HD's ease of control.
RS-232 SERIAL PORT
The RS-232 serial port may be connected to an external computer or control device to allow the external device to transmit control commands to the AVR. The port is bidirectional, so that the AVR can transmit status updates to the control device. Connecting and using the RS-232 port requires technical knowledge, and is best left to a professional custom installer.
If it's available on your video display, an HDMI connection is recommended 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 may be 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 7550HD uses separate terminals for the included FM and AM antennas. The FM antenna uses a 75-ohm F-connector. See Figure 13.

INSTALLATION
You are now ready to begin installing the AVR. Before beginning to connect the various components to the receiver, turn off all devices, including the AVR 7550HD, and unplug their power cords. Don't plug in any of the power cords until you have finished making all of your connections. The receiver generates heat. Select a location that leaves several inches of space on all sides. Avoid completely enclosing the receiver inside an unventilated cabinet. Place components on separate shelves rather than stacking them directly on top of the receiver. Never block the AVR's ventilation slots on the top and side panels. Doing so could cause the AVR to overheat, with potentially serious consequences. Some shelf surface finishes are delicate. Try to select a location with a sturdy surface finish. TIP: Label each cable before connecting it, to avoid mistakes. Write a description of the cable on a blank adhesive label, e.g., "DVD", and fold the label around the cable about 6 inches from the end to be plugged into the AVR. Almost all of the following installation steps are optional, depending on your system. Skip any step that does not apply to your system.
STEP FIVE Connect FM Antenna
Connect the included FM antenna to the 75-ohm FM antenna terminal.
STEP SIX Connect AM Antenna
Assemble the included AM antenna (see Figure 17) and connect it to the AM and Ground antenna terminals. The antenna is not polarized, and either lead may be connected to either terminal.
Figure 17 AM Antenna Assembly
STEP SEVEN Connect XM Antenna Module
If you have purchased an optional XM antenna module designed for XM Ready® devices, plug it into the XM jack. Purchase a subscription and activate the module, following the instructions posted at www.xmradio.com. Place the module within view of a south-facing window.
STEP ONE Connect Source Devices
Leaving all AC power cords unplugged, connect the source devices to the AVR using the audio and video inputs you assigned in Table 2.
STEP TWO Connect TV
Connect the system-best video input on the TV to the corresponding video monitor output on the AVR.
STEP EIGHT Connect USB Device
To play MP3 or WMA audio files or JPEG still-image files stored on a USB storage device, connect the device to the front-panel USB Port, using a cable or connector that is attached to the device or provided by you.
STEP THREE Connect Loudspeakers
After you have placed your loudspeakers in the room as explained on page 21, connect each speaker to its color-coded terminal on the AVR. Maintain proper polarity by connecting the negative terminal on the speaker (usually colored black) to the negative terminal on the AVR (also colored black); and the positive terminal on the speaker (usually red) to the positive terminal on the AVR (color varies by channel; see Table 1 on page 18). If you have a subwoofer, connect its line-level or LFE input to the purple Subwoofer 1 Output. An optional second subwoofer may be connected to the Subwoofer 2 Output. NOTE: If the subwoofer only has speaker-level inputs, after you have configured the AVR using EzSet/EQ II technology as described on page 29, connect the subwoofer's left and right speaker input terminals to the AVR's Front Left and Front Right Speaker Outputs, then connect the front left and right main speakers to the subwoofer's left and right speaker output terminals. Consult the owner's manual for the subwoofer for specific installation instructions.
STEP NINE Connect AVR to Internet
To use the AVR's internal Internet Radio tuner to listen to MP3 or WMA audio streams, connect the Network Jack to the Ethernet port on a router or modem that has Internet access, a home network, or directly to a PC. You may need to contact your Internet service provider (ISP), or the manufacturer of your router, to obtain the information necessary to set up the network connection. See pages 36 and 37.
STEP TEN Connect Remote IR Inputs and Outputs
The AVR 7550HD is equipped with a Remote IR Input, a Zone 2 Input and both full-carrier and stripped Remote IR Outputs to facilitate use of your system with a remote control in a variety of situations. When the AVR 7550HD is placed inside a cabinet or facing away from the listener, connect an external IR receiver, such as the optional Harman Kardon HE 1000, to the Remote IR Input jack. For multizone operation, connect an optional IR receiver, keypad or other control device to the Zone 2 IR Input for remote control of the AVR 7550HD (and any sources connected to the AVR's Remote IR Output) from the remote zone. Signals transmitted through the Zone 2 IR Input will control source selection and volume for the main or remote zone, depending on the setting of the remote's Zone Selector. If a source device is shared with the main listening area, any control commands issued to that source will also affect the main room.
STEP FOUR Connect

AVR 7550HD
harman/kardon
INSTALLATION
If any source devices are equipped with a compatible Remote IR Input, use a 1/8-inch mini-plug interconnect cable (not included) to connect the AVR's Remote IR Output to the source device's Remote IR Input. The AVR 7550HD outputs a "stripped carrier" IR signal through the Remote IR Output, but a full-carrier IR signal is available at the Carrier Remote IR Output. The Carrier Remote IR Output is only available to one sender at a time, which is assigned in the AVR's Zone 2 menu. Depending on whether you select Zone 2, Front or A-BUS, the Carrier Remote IR will only transmit commands received from the Zone 2 IR Input, the front-panel IR receiver or the A-BUS system to a device connected to it. This avoids having conflicting control commands sent to a device from listeners in different areas of the home. To control more than one source device through the Remote IR Output, connect all sources in "daisy chain" fashion, connecting each device's IR output to the next device's IR input, starting with the AVR. Connect devices expecting a full-carrier IR signal to the Carrier Remote IR Output, and assign the desired sending zone in the Zone 2 menu. Use the Remote IR Output for devices expecting a stripped signal. Your main system will be limited to 5.2 channels, affecting playback of programs recorded in 6.1 or 7.1 channels. C. Connect an external amplifier to the Surround Back/Zone 2 Preamp Outputs. This method requires an additional amplifier, but may increase the total number of remote rooms when used with methods A and B. D. Connect an A-BUS hub or other A-BUS components to the A-BUS port. Use Category 5/5e cable, as described in the instructions for your A-BUS components. The A-BUS system carries the audio signal to the remote components, while receiving IR control codes. A hub may distribute audio to many remote rooms. To control source devices exclusively from the remote A-BUS module, connect the AVR's Carrier Remote IR Output to a compatible IR input on the source, and assign the full-carrier output to the A-BUS system in the AVR's Zone 2 menu. This avoids having conflicting control commands sent to a source intended for the A-BUS system. IR commands received from the A-BUS system are also distributed to the AVR's other IR outputs. Visit the Web site at www.harmankardon.com for information on available Harman Kardon hubs, the ABH 4 and ABH 4000, and amplified in-wall modules, the AB 1 and AB 2.
STEP ELEVEN Install a Multizone System
The AVR 7550HD offers several methods of distributing audio to other areas in your home, and it also features video distribution. IMPORTANT SAFETY NOTE: Installing a multizone system typically requires running cables inside walls. Always comply with the appropriate safety codes when installing concealed wiring, particularly all applicable state and local building codes and the NEC (National Electrical Code). Failure to do so may present a safety hazard. If you have any doubt about your ability to work with electrical and telecommunications wiring, hire a licensed electrician or custom installer to install the multizone system. When the system is installed using method B or C below, multizone operation takes over the Surround Back/ Zone 2 amplifier channels, limiting the system in the main listening room to 5.2 channels. Select one or all of these methods for audio distribution: A. Connect an external amplifier to the Zone 2 Audio Outputs. It is recommended that you place the amplifier in the same room as the AVR 7550HD so that a shorter length of interconnect cable is used with a long run of speaker wire to the remote room. A long run of interconnect cable would be subject to signal degradation. Depending on your amplifier, distribute the audio signal to a single pair of speakers, or to several pairs placed in different rooms. The Zone 2 Audio Outputs offer the benefit of 7.2-channel audio in the main room simultaneously with multizone operation. However, the benefit is achieved with the expense of an additional component, i.e., the amplifier. B. Connect the remote room's speakers directly to the Surround Back/Zone 2 Speaker Outputs. Reassign the Surround Back amplifier channels to power the speakers (see page 47).
Connect a Video Display Device or Switcher
To add video distribution to your multiroom system, connect the Multizone Video Output either directly to the video display in the remote room or to any optional video distribution switchers or amplifiers that may be required. NOTES: · Only composite video is output to the multizone system. · S-video, component or HDMI video sources may not be routed through the multizone system. Make a second, composite video connection for the multizone system. · When connecting the AVR 7550HD to the remote room's video display, distance limitations may exist for composite video connections. Although the use of low-loss coax cables may reduce signal loss, optional distribution amplifiers may occasionally be required when long cable runs are used.
Connect IR Control Devices to the Zone 2 IR Input
For methods A, B and C, connect an IR control device to the Zone 2 IR Input for remote-room control of the multizone system, source devices and volume in the remote zone. An A-BUS system does not require a separate IR control connection. NOTE: Only analog audio sources are available to the multizone system. For digital sources, make a second, analog audio connection. The USB, The Bridge II and Internet Radio sources are available to the multizone system.

INSTALLATION
STEP TWELVE Plug in AC Power Cords
Before plugging the AVR into an unswitched electrical outlet, make sure the Main Power Switch behind the front-panel door is off, to prevent the possibility of damaging the AVR in case of a transient power surge. When pressed in, the switch is on. When pressed again to unlatch it, the switch pops out. You may plug one device that draws no more than 50 watts into the AC Switched Accessory Outlet on the rear panel. Turn on the device's mechanical or master power switch, and that device will power on any time the AVR 7550HD is turned on (some devices may require additional steps to power on from their standby mode). If the device has a clock or must always be on (such as a cable set-top box programmed to make recordings), do not plug it into this outlet. The AVR 7550HD is equipped with a detachable power cord, allowing you to fully wire your system before installing the AVR. Plug the male end of the cord into an unswitched AC outlet, and the female end into the AVR 7550HD. It is recommended that you copy the appropriate information from the Table 2 worksheet to Table A5 in the appendix for future reference, in the event changes are made to the system components. the Harman Kardon DMC 1000 digital media center and TVs.
