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

DTS

and DTS-ES®data streams. Two-channel stereo and matrix surround sources benefit from all current Dolby Pro Logic latest version of our proprietary Logic 7

Digital, Dolby Digital EX,

IIx modes and DTS Neo:6.®The

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 lip sync errors – commonly seen when digital video processing is used in a source, program or video display – are eliminated.

Thanks to a wide range of multizone options and a standard ZR 10 remote control, the AVR 645 makes it possible to watch and listen to a separate source in one room while the main home theater uses a different source. Using the assignable rear surround channel amplifiers, you may create a basic remote listening zone without any additional equipment, or the unit’s multiroom outputs may be used to feed an optional, external power amplifier and volume control. For one-wire multiroom connectivity, the AVR 645 is A-BUS/

READY

, requiring only a single Category 5/5e cable run and an optional remote module to power a pair of remote speakers while controlling volume and enabling full control over the program source and connected IR-controlled devices.

Along with the latest advances in digital audio and video technology, Harman Kardon recognizes that some things remain constant, and in the case of the AVR 645 that is a requirement for audio power best served by our time-honored high-current, ultrawidebandwidth amplifier design. The AVR 645’s sevenchannel amplifier provides the power to reproduce the loudest crescendos or cinema sound effects while remaining virtually free from distortion or system noise.

With a combination of state-of-the-art circuitry, digital technology and proven performance with an elegant design that is compatible with the latest source components and video displays, the AVR 645 represents the culmination of Harman Kardon’s fifty-plus-year history of delivering the finest sonic performance.

SAFETY INFORMATION

Important Safety Information

Verify Line Voltage Before Use

Your AVR 645 has been designed for use with 120-volt AC current. Connection to a line voltage other than that for which it is intended can create a safety and fire hazard and may damage the unit.

If you have any questions about the voltage requirements for your specific model, or about the line voltage in your area, contact your selling dealer before plugging the unit into a wall outlet.

Do Not Use Extension Cords

To avoid safety hazards, use only the power cord attached to your unit. We do not recommend that extension cords be used with this product. As with all electrical devices, do not run power cords under rugs or carpets, or place heavy objects on them. Damaged power cords should be replaced immediately by an authorized service center with a cord meeting factory specifications.

Handle the AC Power Cord Gently

When disconnecting the power cord from an AC outlet, always pull the plug; never pull the cord. If you do not intend to use the unit for any considerable length of time, disconnect the plug from the AC outlet.

Do Not Open the Cabinet

There are no user-serviceable components inside this product. Opening the cabinet may present a shock hazard, and any modification to the product will void your guarantee. If water or any metal object such as a paper clip, wire or a staple accidentally falls inside the unit, disconnect it from the AC power source immediately, and consult an authorized service center.

CATV or Antenna Grounding

If an outside antenna or cable system is connected to this product, be certain that it is grounded so as to provide some protection against voltage surges and static charges. Section 810 of the National Electrical Code, ANSI/NFPA No. 70-1984, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes and requirements of the grounding electrode.

NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call the CATV (cable TV) system installer’s attention to article 820-40 of the NEC that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as possible.

INSTALLATION AND CONNECTIONS

System Installation

After unpacking the unit, locating it in a place with adequate ventilation 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.

IMPORTANT NOTE: For your personal safety and to avoid possible damage to your equipment and speakers, it is always good practice to turn off and unplug the AVR and ALL source equipment from the AC output before making any audio or video system connections.

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.

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

CD Audio Inputs 6.

NOTE: If your 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 it is distorted.

2. Connect the analog Play/Out jacks of a cassette deck, MD, CD-R or other audio recorder to the Tape Inputs 4. Connect the analog Record/In jacks on the recorder to the on the AVR 645.

3. Connect the output of a digital source such as

a CD or DVD changer or player, a video game, a digital satellite receiver, an HDTV tuner or digital cable set-top box or the output of a compatible computer sound card to the

Digital Audio Inputs

4. Connect the coaxial or optical XY on the rear panel of the AVR 645 to the matching digital input connections on a CD-R, MiniDisc or other digital recorder.

5. Assemble the AM loop antenna supplied with the unit so that the tabs at the bottom of the antenna loop snap into the holes in the base. Connect it to the

AM Antenna Connections i .

6. Connect the supplied FM antenna to the

Antenna Jack

an external roof antenna, an inside powered or wire-lead antenna or a connection from a cable TV system. If the antenna or connection uses 300-ohm twin-lead cable, you must use an optional 300-ohm-to-75-ohm adapter to make the connection.

Digital Audio Outputs

7. Connect the front, center, surround and surround back speaker outputs tive 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 cable Remember that when specifying cable, the lower the number, the thicker the cable.

Cable with a gauge of 16 may be used for short runs of less than 10 feet. We do not recommend that you use cables with an AWG equivalent of 18 or higher, 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 UL, CSA or other 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 NEC and/or the applicable 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 has a specific color code, as noted on page 8. However, most speakers still use a red terminal for the positive (+) 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 may vary from this configuration. To ensure proper phase and optimal performance, consult the identification label 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 645.

8. Connections to a subwoofer are normally made via a line-level audio connection from the

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.

9. If an external audio source such as a DVD-Audio, SACD or high-definition optical disc player with 5.1 or 7.1 analog audio outputs is part of your system, connect the outputs of the source to the 8-Channel

Direct Inputs c.

Analog Video Equipment Connections

Analog video components are connected in the same manner as audio components. Again, the use of highquality interconnect cables is recommended to preserve signal quality.

1. Connect the Video Play/Out jacks of a standard (composite) video (or S-video outputs of a digital video) recorder or conventional VCR to the

8. To use a portable audio/video product such as a camcorder, media player or digital still camera with the AVR, or connect a video game console or other source that may not always be connected to the AVR, connect the video outputs of the source to the

Video 4 Input/Output Jacks N, behind the Front-Panel Door 8. If the source has digital

audio outputs, connect them to the

Digital Input K or the Coaxial 4 Digital Jack M.

CONNECTION NOTES:

• When making connections to the Component Video Inputs

b digital audio inputs, it is a good idea to make note of which jacks are connected to which source, using the Worksheet in the Appendix. This will help simplify the configuration process.

• When connecting a source device such as a cable set-top box where the audio streams may change between digital and analog as you change channels, we recommend that you make both analog and digital connections. The AVR’s Auto Poll feature will automatically sense when the digital stream is replaced by an analog output and switch the input accordingly. (See page 24 for more information on the Auto-Poll feature.) This dual connection is not required for sources (such as DVD players or video games) that always output a digital stream.

9. Connect the AVR to your video display using one of the following connections:

• If you have a video display with an HDMI or DVI input, make the connection using the Output K, as described in the next section.

• If your video display has component video inputs (Y/Pr/Pb), connect the

Video/Monitor Outputs

• If your display does not have digital or component video inputs, connect the Output P on the AVR to the matching input on your display. Only one connection is needed, and S-video is the higher quality signal.

HDMI Connections

HDMI™is the abbreviation for High-Definition Multimedia Interface, which is quickly becoming the standard connection point between advanced video/audio source products and displays, particularly for high-definition video signals. HDMI is a digital connection, eliminating the need to con-

Component

Video Monitor

vert 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 one-wire 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 DVIequipped 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 multi-

channel or 2-channel PCM audio signals only. Connect the HDMI output of a 1.0 source to either

HDMI Inputs L on the AVR. If the product

of the is a DVD-Audio player or other source that has multichannel analog audio outputs, connect them to the 8-Channel Direct Inputs c. With an HDMI 1.0 source, 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 aM or Optical bK Digital Inputs.

• 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 AVR. If the player has SACD capability, you will need to connect the analog outputs of the source to the

8-Channel Direct Inputs c.

• HDMI 1.2

as shown above for HDMI 1.1.

• It is not possible to feed an analog audio or composite or S-video signal to a recorder or the AVR’s

(and higher) sources should be connected

HDMI Inputs L on the

multizone system when an HDMI input is in use. If an HDMI-equipped source also has analog audio and video outputs, connect them to the Video TU and Audio ef inputs.

• In some instances, HDMI-equipped sources will not permit more than one video output at a time, and thus you cannot use the same source in the main listening room, and with the recorder at the same time. This is not a fault of the AVR, but rather a function of the content-protection systems that are part of the HDMI standard.

HDMI Output Connections

Connect the HDMI Output K 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.

Video 2 or Video 3

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 smokedglass cabinet door, the obstruction may prevent the remote sensor from receiving commands. In this event, an optional remote sensor may be used. Connect the output of the remote sensor to the IR Input ﬂ.

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 Input jack on Harman Kardon or other compatible equipment.

Multiroom Audio Connections

The AVR 645 is equipped with multizone capabilities that allow it to send a separate audio source to the remote zone from the one selected for use in the main room.

Depending on your system’s requirements, three options are available for audio connection:

Option 1: Use high-quality, shielded audio interconnect cable from the AVR 645’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 645, plug the audio interconnect cables into the

Audio Outputs

Option 2: Connect the Multiroom Audio Outputs

8 on the AVR 645 to the inputs of an optional stereo power amplifier. Run high-quality speaker wire from the amplifier to the speakers in the remote room.

Option 3: Taking advantage of the AVR 645’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 645 in the main listening room, but you will be able to add another listening room without external power amplifiers. To use the internal amplifiers to power a remote zone, connect the speakers for the remote room location to the

NOTE: For all options, you may connect an optional IR sensor in the remote room to the AVR 645 via an appropriate cable. Connect the sensor’s cable to the Multiroom IR Input e on the AVR 645 and use the ZR 10 remote to control the room volume. You may install an optional volume control between the output of the amplifiers and the speakers in options 1 and 2.

A-BUS®Installation Connections

The AVR 645 is among the few receivers available that offer built-in A-BUS/ with an optional A-BUS product, you have all the benefits of remote zone operation without the need for an external power amplifier.

To use the AVR 645 with an approved A-BUS product, simply connect it to the AVR 645 using standard Category 5 wiring that is properly rated for the specific in-wall installation. Terminate the wiring at the receiver end to a standard RJ-45 connector in compliance with the instructions furnished with the A-BUS product.

No further installation or adjustment is needed, as the A-BUS jack on the AVR 645 routes the signals to their

RS-232 Connections The AVR 645 is equipped with an RS-232 Serial

Connection Port

compatible, optional, external computer, keypad or control system for bidirectional 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 645’s RS-232 port is a standard D-SUB 9 connection, but to ensure compatible and proper operation, specific software commands and pin wiring schemes may be required.

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 panel.

NOTES ON USB:

• The USB port on the AVR 645 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 645’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 Connection

The AVR 645 is equipped with a low-voltage trigger that may be used to control a wide variety of compatible, optional devices that respond to voltage actuation commands. This includes external audio power amplifiers, video screens, motorized blinds and other compatible products in a home theater or automation system.

Due to the complexity of interfacing with powercontrolled devices, we strongly recommend that they be installed by a qualified professional.

IMPORTANT NOTE ON THE TRIGGER CONNECTION:

The current draw from the trigger jack cannot exceed 1.0mA.

XM Radio Connections

XM Radio is a satellite-delivered, subscription-based, programming service that provides a wide range of music, sports, news and information programming with digital audio quality. The AVR 645 is XM Connect and Play-ready, which means that you can easily add the XM service to your home audio system by purchasing an XM antenna module or Passport system, activating an account with XM and then making a simple, singlecable connection to your AVR.

To purchase an XM antenna module or Passport system, consult your dealer, or contact XM Radio at www.xmradio.com. After following the instructions packed with the module, place the XM antenna near a south-facing window and run the cable to the AVR. Connect the plug at the end of the cable to the

Ready Module Input

Passport system, remember that the Passport card must be inserted for the system to operate. Once the connection is made, follow the instructions on page 41 for more information on listening to XM Radio.

NOTES on XM Radio:

• XM Radio requires the purchase of additional, optional hardware and a separate subscription to the XM service.

• XM Radio is available only in the continental United States and Canada. It is not available in Alaska or Hawaii.

• XM reception requires that the antenna be able to “see” the XM satellites or receive a signal from one of the XM ground-based repeaters. Depending on your installation and location, XM service may not be available in some areas.

When all audio, video and system connections have been made, the final steps before listening to your new AVR are to make the configuration adjustments that tailor the unit to the other components in your system, as well as accommodate your personal listening preferences. A few minutes spent to correctly calibrate and configure your system will greatly add to your listening pleasure.

Speaker Selection and Placement

While the most seamless surround sound reproduction comes from the use of speakers with identical or carefully matched driver elements at each position, no matter which brand or type of speakers you prefer, it is always best to use the same model or series for the left front, center and right front speakers. Similarly, it is also desirable to use the same model or series for the surround speakers. This ensures that the soundstage will be relatively seamless when a sound moves from one side of the room to the other.

Speaker Placement

Once you have selected your speakers, it is important that they be placed in positions that enable them to do the best job of reproducing the sound as it was meant to be heard, regardless of the program content. The placement of speakers can have a noticeable impact on the accuracy of the surround process, particularly in multichannel systems.

When placing your speakers in a listening room, picture an imaginary circle starting at the center of your video screen that arcs around the room with the prime listening position, or “sweet spot,” at the center of the circle. Depending on the number of speakers in your system, there is a recommended placement along the circle for each speaker, though the specific construction of your room, taking into account the available walls, bookcases, or floor space at which the speakers may be placed will obviously have some impact on where the speakers are ultimately located. As a general rule, try to place all speakers so that they are positioned at the same height as your ears when you are seated at the prime listening position.

Use the following suggestions as a guide, and make the changes needed to fit the speakers to your room. Don’t be afraid to experiment a bit until you find the right combination of locations that works for you. At the end of the day, there is no real “right” or “wrong” place to put the speakers; work to optimize their locations so that audio moves across the front of the room smoothly, without seeming to jump from one speaker to another.

Front Left/Right Speakers

The recommended placement for front left/right speakers is at the 30-degree position with reference to the center channel speaker. The distance between them should be about the same as the distance from the center channel speaker to the prime listening position.

Although the natural tendency is to place the speakers so they are parallel to the wall behind them, and thus in line with the video screen, the preferred placement is to angle the speakers slightly (“toe in”) so that they point at the prime listening position.

Center Channel Speaker

The ideal location for the center channel speaker is at “0 degrees” in our circle, directly in front of the prime listening position. Place the center channel speaker as close to the top (or bottom) of the video screen as possible so that when you position the front left/right speakers the tweeters of all three front channel speakers are within 24" of one another.

Surround Speakers for 5.1 Systems

In a 5.1 surround system, an additional pair of left/right speakers is added. Although many believe that these speakers should be placed at the rear of the room, the preferred position for them is at the sides of the room, with rear placement a second option when room conditions prevent the use of sidemounted surround speakers.

When side-wall placement is possible, place the left/right surround speakers at a point that is 110 degrees along our circle from the center of the video screen. This translates to placing them to the side and slightly behind your preferred listening position. If possible, angle the speakers in slightly so that they are pointing toward the listener’s ears.

5.1 Placement Diagram

If it is not possible to place the surround speakers at the sides of the room, the alternate position is at the back of the room, at a spot that is about 150 degrees around our circle from the center of the video screen. Another way to spot the optimal, alternate rear-wall mounting position is to place the left surround speaker on the back wall so that it points directly at the front right speaker, and to have the right surround speaker point directly at the front left speaker. If possible,

aim the surround speakers so that they point inward, toward the listening area, rather than perpendicular to the walls.

Surround Speakers for 6.1 Systems

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.

6.1 Placement Diagram

NOTE: The 6.1-channel configuration is not recommended for the AVR 645. We strongly recommend a 7.1-channel installation as described below. When

6.1-channel materials are played through a 7.1-channel

system, the same surround back channel information is played through both the left and right surround back speakers.

If you are only able to install a single surround back speaker at this time, we suggest you install all of your speakers except the surround back speaker, and run the EzSet/EQ procedure for a 5.1-channel system (see page 29). After EzSet/EQ has finished, connect the single surround back speaker to the

Back Speaker Outputs

E. Then follow the instruc-

left

Surround

tions starting on page 30 to manually configure your surround back speaker.

We recommend that you consider adding a second surround back speaker as soon as possible.

Surround Speakers for 7.1 Systems

For the ultimate home theater experience, a 7.1 surround system uses both traditional surround left/right channels and a surround back left/right speaker pair. In a 7.1 system, the front left/center/right speakers remain in the same place as they would be for a 5.1 or 6.1 system, but due to the number of
