The AVR 645 has the most extensive range of audio and video processing, control and connectivity options ever offered by Harman Kardon, enabling it to provide the best possible audio and video reproduction with any type of source material. Teaming advanced processing circuitry with proprietary technologies such as EzSet/EQ, the AVR 645 seamlessly integrates every component in your entertainment system to deliver the best possible sound and images.

Some of the leading-edge features that are available with the AVR 645, such as HDMI

™

connectivity, are new to even the most experienced home theater enthusiast.

To obtain the maximum enjoyment from your new receiver, we urge you to read this manual. A few minutes spent learning the functions of the various controls will enable you to take advantage of all the power the AVR is able to deliver.

If you have any questions about this product, its installation or its operation, please contact your retailer or custom installer. They are your best local sources of information.

Description and Features

The AVR 645 serves as the hub of your home entertainment system, providing a wide range of listening possibilities for almost any audio or video program source, whether it is the broadcast of a movie or sporting event in HDTV or a vintage mono or stereo recording. When playing digital audio sources from either the conventional optical and coaxial inputs, or through the HDMI 1.1 compliant connections, the AVR 645 decodes Dolby Digital, Dolby Digital EX, DTS and DTS-ES data streams.Two-channel stereo and matrix surround sources benefit from all current Dolby Pro Logic IIx modes and DTS Neo:6. The latest version of our proprietary Logic 7

process is on-board to create a wider, more enveloping sound field and more defined surround channel positioning, regardless of the type of source material. Additional audio playback and processing options include a direct connection to compatible computer-based sources through a direct USB connection.

The AVR 645 takes the “video” part of its name seriously.Along with two HDMI inputs and three 100MHz analog component video inputs, the AVR 645 converts incoming analog signals to an HDMI output or converts composite and S-video to component for single wire connections.Tying audio and video together, the AVR 645 provides A/V sync delay so that the lip sync errors – commonly seen when digital video processing is used in a source, program or video display – are eliminated.

Coax and optical digital outputs are available for direct connection to digital recorders, and both the front panel analog audio/video and coaxial digital jacks may be switched to outputs for use with portable recorders – a Harman Kardon exclusive.Two video recording outputs, preampout and a color-coded eight-channel input make the AVR virtually future-proof, with everything needed to accommodate tomorrow’s new formats right on board.

The AVR 645’s flexibility and power extend beyond your main home theater or listening room. The AVR includes a sophisticated multizone control system that allows you to select one source for use in the main room and a different one (Audio) in a second room. Complete control over volume is possible with a separate infrared control link.To make it easy to operate the AVR from a remote room, a separate “ZR 10” remote is included.

Additional multiroom options include the option to assign two of the AVR’s output channels to the multiroom system and the ability to link the AVR to innovative A-BUS

keypads for multiroom oper-

ation without the need for external amplifiers.

The AVR 645’s powerful amplifier uses traditional Harman Kardon high-current design technologies to meet the wide dynamic range of any program selection.

Harman Kardon invented the high-fidelity receiver more than fifty years ago.With

state-ofthe-art circuitry and time-honored circuit designs, the AVR is the perfect combina digital audio technology, a analog amplifier in an

Surround Back/Multiroom Speaker Outputs: These speaker terminals are normally

used to power the surround back left/surround back right speakers in a 7.1 channel system. However, they may also be used to power the speakers in a second zone, which will receive the output selected for a multiroom system. To change the output fed to these terminals from the default of the Surround Back speakers to the Multiroom Output, you must change a setting in the Multiroom Menu of the OSD system. See page 49 for more information on configuring this speaker output. In normal surround system use, the brown and black terminals are the surround back left channel positive (+) and negative (–) connections and the tan and black terminals are the surround back right positive (+) and negative (–) terminals. For multiroom use, connect the brown and black SBL terminals to the red and black connections on the left remote zone speaker and connect the tan and black SBR terminals to the red and black terminals on the right remote zone speaker.



RS-232 Port: This jack may be used to control the AVR 645 over a bi-directional RS-232 serial control link to a compatible computer or programmable remote control system. Due to the complexity of programming RS-232 commands we strongly recommend that connections to this port for control purposes be made by a trained and qualified technician. This jack may also link to a compatible computer to upgrade the software and operating system of the AVR 645 when appropriate upgrades are available.



Fan Vents: These ventilation holes are the output of the AVR’s airflow system. To ensure proper operation of the unit and to avoid possible damage to delicate surfaces, make certain that these holes are not blocked and that there is at least three inches of open space between the vent holes and any wooden or fabric surface.

IMPORTANT NOTE: The AVR 645’s remote may be programmed to control up to seven devices, including the AVR. Before using the remote, it is important to remember to press the Input Selector button

that corresponds to the unit you wish to operate. In addition, the AVR’s remote is shipped from the factory to operate the AVR and most Harman Kardon CD or DVD players and cassette decks.The remote is also capable of operating a wide variety of other products using the control codes that are part of the remote or by learning commands from other remotes. Before using the remote with other products, follow the instructions on pages 53-54 to program the proper codes for the products in your system.

It is also important to remember that many of the buttons on the remote take on different functions, depending on the product selected using the Input Selector Button

.The descriptions shown here primarily detail the functions of the remote when it is used to operate the AVR.

Installation and Connections

After unpacking the unit, and placing it on a solid surface capable of supporting its weight, you will need to make the connections to your audio and video equipment.

Audio Equipment Connections

We recommend that you use high-quality interconnect cables when making connections to source equipment and recorders to preserve the integrity of the signals.

When making connections to audio source equipment or speakers it is always a good practice to unplug the unit from the AC wall outlet. This prevents any possibility of accidentally sending audio or transient signals to the speakers that may damage them.

1. Connect the analog output of a CD player to the CD inputs

NOTE: When the CD player has both fixed and variable audio outputs it is best to use the fixed output unless you find that the input to the receiver is so low that the sound is noisy, or so high that the signal is distorted.

2. Connect the analog Play/Out jacks of a cassette deck, MD, CD-R or other audio recorder to the Tape Input jacks Record/In jacks on the recorder to the Tape Output jacks

3. Connect the digital output of any digital sources such as a CD or DVD changer or player, advanced video game, a digital satellite receiver, HDTV tuner or digital cable set-top box or the output of a compatible computer sound card to the Optical and Coaxial Digital Inputs



. The FM antenna may be an external roof antenna, an inside powered or wire lead antenna or a connection from a cable system. Note that if the antenna or connection uses 300-ohm twin-lead cable, you should use a 300-ohm-to-75-ohm adapter to make the connection.

7. Connect the front, center and surround speaker outputs



to the respective

speakers.

To ensure that all the audio signals are carried to your speakers without loss of clarity or resolution, we suggest that you use high-quality speaker cable. Many brands of cable are available and the choice of cable may be influenced by the distance between your speakers and the receiver, the type of speakers you use, personal preferences and other factors.Your dealer or installer is a valuable resource to consult in selecting the proper cable.

Regardless of the brand of cable selected, we recommend that you use a cable constructed of fine, multistrand copper with an area greater than

2 mm

Cable with an area of 1.5 mm

may be used for short runs of less than 4 m. We do not recommend that you use cables with an area less than

1 mm

due to the power loss and degradation in

performance that will occur.

Cables that are run inside walls should have the appropriate markings to indicate listing with any appropriate testing agency standards. Questions about running cables inside walls should be referred to your installer or a licensed electrician who is familiar with the applicable local building codes in your area.

When connecting wires to the speakers, be certain to observe proper polarity. Note that the positive (+) terminal of each speaker connection now carries a specific color code as noted on page 7. However, most speakers will still use a red terminal for the postive (+) connection. Connect the “negative” or “black” wire to the same terminal on both the receiver and the speaker.

NOTE: While most speaker manufacturers adhere to an industry convention of using black terminals for negative and red ones for positive, some manufacturers may vary from this configuration. To assure proper phase and optimal performance, consult the identification plate on your speaker or the speaker’s manual to verify polarity. If you do not know the polarity of your speaker, ask your dealer for advice before proceeding, or consult the speaker’s manufacturer.

We also recommend that the length of cable used to connect speaker pairs be identical. For example, use the same length piece of cable to connect the front-left and front-right or surround-left and surround-right speakers, even if the speakers are a different distance from the AVR.

to the line-level input of a subwoofer with a built-in amplifier. When a passive subwoofer is used, the connection first goes to a power amplifier, which will be connected to one or more subwoofer speakers. If you are using a powered subwoofer that does not have line-level input connections, follow the instructions furnished with the speaker for connection information.

HDMI Connections

HDMI™is the abbreviation for High-Definition Multimedia Interface, which is quickly becoming the standard connection point between advanced video/audio source products and displays, particularly for high-definition video signals. HDMI is a digital connection, eliminating the need to convert signals back and forth from digital to analog to deliver a higher quality signal when used with digital sources.The signals carried on HDMI may, but do not always, include audio, offering the possibility of a complete onewire connection from a source to the AVR. However, it is important to note that there are a number of different versions of the HDMI standard in use. Before connecting any HDMI products to your AVR, it is helpful to find out in advance their level of HDMI connectivity.

Some source or display components in your system may use DVI (Digital Video Interface) for digital video connections. DVI carries the same digital video signals as HDMI but uses a larger connector and does not transport audio or control signals. In most cases, you may mix and match DVI and HDMI digital video connections by using optional connector adapters. Note, however, that some DVI-equipped video displays are not compatible with the HDCP copy protection coding that is increasingly carried with signals connected via HDMI. If you have an HDMI source and a DVI-equipped display, you may occasionally be unable to view a program if the display does not include HDCP. This is not the fault of the AVR or your source; it simply indicates that the video display is not compatible.

HDMI Input Connections

The different “Version” levels of HDMI define which type of audio signals it is compatible with. Based on the lowest level of HDMI among your sources, the connections to the AVR should be made as follows:

• HDMI 1.0 sources carry digital video and multichannel or 2-channel PCM audio signals only. Connect the HDMI output of a 1.0 source to either of the HDMI Inputs the product is a DVD-Audio player or other source that has multichannel analog audio outputs, connect them to the 8-Channel

Direct Inputs

particularly a DVD player, make certain that the menus in the source device are set to “Bitstream Out” or “Original” so that 5.1 digital audio is available. If you find that 5.1 Dolby Digital or DTS audio is not available on the HDMI connection, it will be necessary to make an additional connection between the source and the AVR 645 to either the Coaxial or Optical

• HDMI 1.1 sources carry the multichannel digital audio output from DVD-Audio players in addition to the digital video. If you have an HDMI 1.1-equipped product, the only connection needed for listening in the main room is from the HDMI output of the source to either of the HDMI Inputs player has SACD capability, you will need to connect the analog outputs of the source to the 8-Channel Direct Inputs

• HDMI 1.2 (and higher) sources should be connected as shown above for HDMI 1.1, except that a separate analog connection is not needed for SACD players.

and

HDMI Output Connections

Connect the HDMI Outputto an HDMI input on your video display.Thanks to the AVR 645’s video processing system, all video input signals are converted to an HDMI output, so only one connection is required between the AVR and your display.

SCART A/V Connections

For the connections described above your video device needs RCA (cinch) connectors or/and S-Video connectors for all Audio and Video signals: Any normal video device (Not SVHS or High 8) for only playback needs 3 RCA jacks, VCRs for record and playback even 6 RCA jacks. Any S-Video device (SVHS, High 8) needs 2 RCA (Audio) and 1 S-Video jack (Video), if it´s a playback unit, or 4 RCA (Audio In/Out) and 2 S-Video (Video In/Out) jacks, if it´s a recording VCR.

Many european video devices are equipped with RCA (Cinch) or S-Video jacks only partially, not for all audio and video in/outputs needed as described above, but with a so called Scart or Euro-AV connector (almost rectangular jack with 21 pins, see drawings on next page).

In that case the following Scart to Cinch adapters or cables are needed:

• Units for playback, such as satellite receivers, camcorders, DVD or LD players, need an adapter from Scart to 3 RCA plugs, see fig. 1 (normal video devices) or from Scart to 2 RCA+1 S-Video plugs, see fig. 4 (S-Video devices).

• HiFi VCRs need an adapter from Scart to 6 RCA plugs, see fig. 2 (normal video), or from Scart to 4 Audio+2S-Video jacks, see fig. 5 (S-Video VCR). Read carefully the instruction attached to the adapter to find which of the six plugs is used for the record signal to the VCR (connect with the AVR´s Out jacks) and for the playback signal from the VCR (connect with the AVR´s In jacks). Do not misconnect Audio and Video signals. Don´t hesitate to consult your dealer, if you are uncertain.

• If you use only normal video devices the TV monitor needs an adapter from 3 RCA plugs to Scart (fig. 3) only. If also S-Video devices are used an adapter from 2 RCA+1S-Video plugs to Scart is needed additionally (fig. 6), connected to the SCART input on your TV that is provided for S-Video.

Note that only the video plugs (the "yellow" cinch plug in fig. 3 and the S-Video plug in fig. 6) must be connected to the TV Monitor

Output



, and the volume on the TV must be

reduced to minimum.

Important Note for Adapter Cables:

If the cinch connectors of the adapter you’ll use are labeled, connect the Audio and Video ”In” plugs with the corresponding Audio and Video ”In” jacks on the AVR (and with a VCR connect the ”Out” plugs to the ”Out” jacks on the AVR). Note that with some adapter types it may be just turned around: If no signal is audible/ visible when the VCR is playing connect the “Out” plugs to the ”In” jacks on the AVR and turned around. If the adapter plugs are not labeled in that way, pay attention to the signal flow directions as shown in the diagrams above and in the instruction attached to the adapter. If uncertain, don’t hesitate to consult your dealer.

Important Note for the Use of SCART-Cinch Adapters:

When video sources are connected to the TV directly with a SCART cable, specific control signals apart from Audio/Video signals will be fed to the TV. These specific signals are: With all video sources, the signal for automatic input selection that switches the TV automatically to the appropriate input as soon as the video source is started. And with DVD players, the signals automatically turning the TV to 4:3/16:9 format (with 16:9 TVs or with 4:3 TVs with selectable 16:9 format) and turning the RGB video decoder of the TV on or off, depending on the DVD player´s setting. With any adapter cable, these control signals will be lost and the appropriate setting of the TV must be made manually.

Note for RGB signal with SCART:

If you use a unit providing RGB signals on a SCART output (as e.g. most DVD players do) and you want to use that RGB signal, this SCART output must be connected directly to your TV. Although the AVR can switch three-way video signals (like component signals Y/Pb/Pr), most TVs need separate sync signals for RGB (also with SCART) that cannot be switched and provided by the AVR. RGB signals can be pathed through the AVR only when no separate sync signal is needed (see last ”Video Connection Note” on page 16).

INSTALLATION AND CONNECTIONS 19

Installation and Connections

System and Power Connections

The AVR 645 is designed for flexible use with multiroom systems, external control components and power amplifiers.

Main Room Remote Control Extension

If the receiver is placed behind a solid or smoked glass cabinet door, the obstruction may prevent the remote sensor from receiving commands. In this event, the remote sensor of any Harman Kardon or other compatible device, not covered by the door, or an optional remote sensor may be used. Connect the Remote IR Output of that device or the output of the remote sensor to the Remote IR Input jack

If other components are also prevented from receiving remote commands, only one sensor is needed. Simply use this unit’s sensor or a remote eye by running a connection from the Remote IR Output jack



to the Remote IR Input jack on Harman Kardon or other compatible equipment.

Multiroom IR Link

The key to remote room operation is to link the remote room to the AVR’s location with wire for an infrared receiver and speakers or an amplifier. The remote room IR receiver (this can be an optional IR receiver or any other remotable Harman Kardon device in the remote room with IR sensor integrated) should be connected to the AVR via standard coaxial cable. Connect the Remote IR Output of the device or of the optional sensor with the Multiroom IR Input jack



on the AVR’s rear panel.

If other Harman Kardon compatible source equipment is part of the main room installation, the Remote IR Output jack



on the rear panel should be connected to the IR IN jack on that source device.This will enable the remote room location to control source equipment functions.

When a remote IR sensor is used to control nonHarman Kardon source equipment, we recommend that you make a direct connection or use an optional, external IR “blaster” connected to the Remote IR Carrier Output Jack are in doubt as to which IR Output jack to use for the equipment in your system, contact your dealer or installer, or the manufacturer’s support site and ask whether the unit to be controlled uses “full carrier” or “stripped” carrier IR commands.When “full carrier commands” are used, make the connection to the Remote IR Carrier

Output Jack

NOTE: All remotely controlled components must be linked together in a “daisy chain”. Connect the IR OUT jack of one unit to the IR IN of the next to establish this chain.

Multiroom Audio Connections

Depending on your system`s requirement and distance from the AVR to the remote room, three options are available for audio connection:

Option 1: Use high-quality, shielded audio interconnect phono cable from the AVR’s location to the remote room. In the remote room, connect the interconnect cable to a stereo power amplifier. The amplifier will be connected to the room’s

speakers.At the AVR, plug the audio interconnect cables into the Multiroom Output Jacks on the AVR’s rear panel.

Option 2: Place the amplifier that will provide power to the remote location speakers in the same room as the AVR, and connect the Multiroom Output jacks



on the rear panel of the AVR to the audio input of the remote room amplifier. Use the appropriate speaker wire to connect the optional power amplifier to the remote speakers. High-quality wire of at least

2.5 mm

is recommended for long multiroom

connections.

Option 3: Taking advantage of the AVR’s built-in seven-channel amplifier, it is possible to use two of the amplifier channels to power speakers in the remote room. When using this option you will not be able to use the full 7.1-channel capabilities of the AVR in the main listening room, but you will be able to add another listening room without additional external power amplifiers.To use the internal amplifiers to power a remote zone, connect the speakers for the remote room location to the Surround

Back/Multiroom Speaker Outputs

using the remote room you will need to configure the amplifiers for surround operation by changing a setting in the Multiroom menu, following the instructions shown on page 49.

NOTE: For all options, you may connect an optional IR sensor (Harman Kardon He 1000) in the remote room to the AVR via an appropriate cable. Connect the sensor’s cable to the

Multiroom IR Input

A-BUS Installation Connections

The AVR is among the very few receivers available today that offers built-in A-BUS/

READY

operation. When used with an optional A-BUS keypad or control module, you have all the benefits of remote zone operation without the need for an external power amplifier.

To use the AVR with an approved A-BUS product, simply connect the keypad or module that is in the remote room to the AVR using standard “Category 5” wiring that is properly rated for the inwall use specific to the installation. Terminate the wiring at the receiver end to a standard RJ-45 jack in compliance with the instructions furnished with the A-BUS module.

No further installation or adjustment is needed, as the A-BUS connector on the AVR routes the signals in and out of the keypad to their proper destination for power, signal source and control. The output fed to the A-BUS jack is determined by the AVR’s multiroom system, and the menus may be used as is.

RS-232 Connections The AVR is equipped with an RS-232 Serial Connection Port



that may be used for two purposes.When the port is connected to a compatible, optional, external computer, keypad or control system the AVR is capable of bi-directional communications that enable the external system to control the AVR, and for the AVR to report status and handshake data back to the controller. Use of the RS-232 port for this type of control requires specific technical knowledge, and we recommend that any connection and programming for control be made by a trained installer or technician familiar with the equipment being used.

The physical connection to the AVR’s RS-232 port is a standard D-9 connection but to assure compatible and proper operation, specific software commands and pin wiring schemes may be required.

20 INSTALLATION AND CONNECTIONS

Installation and Connections

USB Connections

The AVR 645 is one of the few A/V receivers to offer a USB connection that may be used for both playback of compatible audio content from a computer and for loading of system updates (when available).

The physical connection between a computer and the AVR is a simple one, requiring only a cable with a USB “A” type connector on one side and a USB “Mini B” on the other.

Connect the larger, “A” connector on the cable to your computer or a USB hub and the end with the “Mini” USB connector to the USB Jack on the AVR’s rear panel.

NOTES ON USB:

• The USB jack on the AVR is for connection to a computer, or to a hub connected to a computer, only. DO NOT connect it directly to other devices such as card readers, USB memory storage devices, external hard drives, USB accessories, digital cameras or cellular phones. Connection to these devices may cause damage to the device and/or the AVR that is not covered by the AVR’s warranty.

• The AVR’s USB connection may only be used for audio playback and system upgrades. It may not be used for other purposes, such as system control, video or still-image playback.

Trigger Jack Connection The AVR is equipped with a low-voltage Amp Trigger Jack

optional, external power amplifiers, screen motors, motorized blinds or other compatible products that may be part of a home theater installation. Once the connections are made, operation is seamless in that the low-voltage control signal is sent to the screen, blinds or other device when the AVR is turned on, and it is turned off along with the AVR. Due to the

complexity of interfacing with powercontrolled devices, we strongly recommend that the installation be done by a qualified installer.

The AVR’s trigger jack is a 3.5mm mono plug that delivers a 5-volt DC signal to the center pin (“tip”) of the plug (+) with the outer shaft (“ring”) of the plug as the negative (–) or ground connection.

AC Power Connections

This unit is equipped with an accessory AC outlet. It may be used to power accessory devices, but should not be used with high-current draw equipment such as power amplifiers.The total power draw to the Switched Outlet not exceed 100 watts.

The Switched when the unit is on completely.This is recommended for devices that have no power switch or a mechanical power switch that may be left in the “ON” position.

NOTE: Many audio and video products go into a Standby mode when they are used with switched outlets, and cannot be fully turned on using the outlet alone without a remote control command.

The AVR features a removable power cord that allows wires to be run to a complex installation so that the unit, itself, need not be installed until it is ready for connection. When all connections described above have been made, connect the AC Power cord to the AC Power Cord Jack

The AVR draws significantly more current than other household devices such as computers that use removable power cords. For that reason, it is important that only the cord supplied with the unit (or a direct replacement of identical capacity) be used.

Once the power cord is connected, you are almost ready to enjoy the AVR’s incredible power and fidelity!

Speaker Selection

No matter which type or brand of speakers is used, the same model or brand of speaker should be used for the front-left, center and front-right speakers.This creates a seamless front soundstage and eliminates the possibility of distracting sonic disturbances that occur when a sound moves across mismatched front-channel speakers.

Speaker Placement

The placement of speakers in a multichannel home-theater system can have a noticeable impact on the quality of sound reproduced.

Depending on the type of center-channel speaker in use and your viewing device, place the center speaker either directly above or below your TV, or in the center behind a perforated front-projection screen.

Once the center-channel speaker is installed, position the left-front and right-front speakers so that they are as far away from one another as the center-channel speaker is from the preferred listening position. Ideally, the front-channel speakers should be placed so that their tweeters are no more than 60cm above or below the tweeter in the center-channel speaker.

They should also be at least 0.5 meter from your TV set unless the speakers are magnetically shielded to avoid colourings on the TV screen. Note that most speakers are not shielded, even with complete surround sets only the Center speaker may be.

Depending on the specifics of your room acoustics and the type of speakers in use, you may find that imaging is improved by moving the front-left and front-right speakers slightly forward of the center-channel speaker. If possible, adjust all front loudspeakers so that they are aimed at ear height when you are seated in the listening position.

Using these guidelines, you’ll find that it takes some experimentation to find the correct location for the front speakers in your particular installation. Don’t be afraid to move things around until the system sounds correct. Optimize your speakers so that audio transitions across the front of the room sound smooth.

When the AVR is used in 5.1-channel operation, the preferred location for surround speakers is on the side walls of the room, at or slightly behind the listening position. In a 7.1-channel system, both side surround and back surround speakers are required. The center of the speaker should face you (see below).

A 6.1 surround speaker adds an additional center back surround speaker to the system, enabling you to enjoy the benefits of advanced surround modes such as Dolby Digital EX, DTS-ES and Harman Kardon’s proprietary Logic 7/7.1 processing.

To step up to a 6.1 system, first place the speakers for a 5.1 system.The “sixth” speaker should ideally be placed at the center of the room’s rear wall, pointing directly toward the front center channel speaker.
