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.

h. The FM antenna may be

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

Output

1 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.

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

Coaxial a or Optical b digital inputs, or the Analog DVD Audio Inputs Z. You may change

the assignment in the menu as described on page 24, or by using the front-panel Digital Input Selector F.

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.

AC Power Connections

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

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

speakers involved, the placement of the surround speakers is different.

In a 7.1 system, you should place the main surround left/right speakers at the 90-degree point on our circle. A good way to visualize proper surround speaker positioning for 7.1 is to place the speakers directly to the left and right of the ears of someone sitting in the prime listening spot. The two speakers should ideally face toward each other.

The additional Surround Back Left/Right speakers are placed at about 150 degrees on the circle, pointing inward, toward the listening area. The easiest way to visualize the placement of these speakers is to place the surround back left speaker directly opposite the right front speaker and to place the surround back left speaker directly opposite the left front speaker.

7.1 Placement Diagram

Subwoofer Placement

Since subwoofers produce nondirectional sound, they may be placed almost anywhere in a room. Actual placement should be based on room size and shape and the type of subwoofer used. One method of finding the optimal location for a subwoofer is to begin by placing it in the front of the room, about six inches from a wall, or near the front corner of the room.

Another method is to temporarily place the subwoofer at your normal listening position, and then walk around the room until you find a spot where the subwoofer sounds best. Place the subwoofer in that spot. You should also follow the instructions of the subwoofer’s manufacturer, or you may wish to experiment with the best location for a subwoofer in your particular listening room.

For more information on subwoofer placement, as well as a variety of topics relating to audio and home theater, visit the Technology section of our Web site at www.harmankardon.com. Links are provided there to informative white papers written by the acoustic and

electronics experts at Harman Kardon and at our parent company, Harman International Industries, Inc.

NOTES ON SPEAKER PLACEMENT:

1. The limitations of your listening room, including the placement of walls and furniture, may make it difficult to follow the speaker placement suggestions shown above. Depending on the specific layout of the room, here are some ways to compensate for unusual conditions:

• Try to follow the suggested placement, but move the speakers within a few feet from the preferred locations.

• Regardless of where they are placed, always try to make certain that the main surround speakers are the same distance from the front speakers. (For example, try not to have the right surround speaker further back into the room than the left surround speaker.)

• If it is not possible to wall-mount or place speakers on a shelf, consider the use of optional floor stands, available for many speakers.

2. When using ceiling-mounted in-wall speakers, follow the same guidelines shown for conventional floorstanding or shelf-mounted speakers.

System Setup

Once the speakers have been placed in the room and connected, the remaining steps in the setup process are to assign input and output connections, make any video or audio adjustments, select a surround mode, program the AVR 645’s bass management system for the type of speakers used in your system, calibrate the output levels and set the delay times used by the surround sound processor.

Although it is necessary to assign input/output settings and surround mode choices manually, we recommend that you take advantage of the power and precision of EzSet/EQ to automatically select and enter the settings for all other audio parameters. This will not only you time; it will ensure that your room is calibrated equalized with an accuracy not possible when these settings are made manually.

You are now ready to power up the AVR 645 to begin these final adjustments.

1. Make certain that the AC power cord is firmly inserted into the

AC Power Cord Socket I

and plug the cord into an unswitched AC outlet. To maintain the unit’s safety rating, DO NOT substitute the power cord for one with lower current capacity.

2. Press the behind the

and

that the illumination around the

Switch

unit is in the Standby mode.

3. Carefully remove the protective plastic film from the front-panel lens. If left in place, the film will prevent proper operation of the remote control.

4. Install the four supplied AAA batteries in the main remote as shown. Be certain to follow the (+) and (–) polarity indicators that are in the

battery compartment. (The ZR10 remote

requires two AAA batteries.)

5. Turn the AVR 645 on either by pressing the Standby/On Switch 1 on the front panel, or via the remote by pressing the

Using the On-Screen Display

When making the following adjustments, you may find it easier to use the AVR 645’s on-screen display system. These easy-to-read displays give you a clear picture of the current status of the unit and make it easy to see which speaker, delay, input or digital selection you are making.

To view the on-screen menus, make certain you have made a video or HDMI connection to the appropriate matching input of your TV or projector. In order to view the AVR 645’s displays, the correct video source must be selected on the video display.

IMPORTANT NOTE: When viewing the on-screen menus using a CRT-based projector, plasma display or direct-view CRT monitor or television, it is important that they not be left on for an extended period of time. The constant display of a static image such as these menus may cause the image to be permanently “burned into” the projection tubes, plasma screen or CRT display. This type of damage is not covered by the AVR 645 warranty and may not be covered by the projector/TV set’s warranty.

The AVR 645 has two on-screen display modes, “Semi-OSD” and “Full-OSD.” When making configuration adjustments, it is recommended that the full-OSD

Setting the System Configuration Memory

The AVR 645 features an advanced memory system that enables you to establish different configurations for the component video assignment, digital input and surround mode and other settings for each input source. This flexibility enables you to customize the way in which you listen to each source and have the AVR 645 memorize those settings. Once these settings are made, they will automatically be recalled whenever you select that input.

To simplify initial configuration and operation, the AVR 645 has been preconfigured with input settings that are typical for home theater systems. These settings are detailed in the worksheets in the Appendix. Before adjusting the input settings, it is a good idea to compare your input connections to the defaults so that you may see where changes need to be made.

Before using the unit, you may want to change the settings for some inputs so that they are properly configured to reflect the use of digital or analog inputs, the type of video display and speakers installed, and the surround mode specifics of your home theater system.

In/Out Setup

The first step is to configure each input source. When an input is selected, selves to that input and be stored in a nonvolatile memory. Once made, the selection of an input will automatically recall those settings. For that reason, the procedures described below must be repeated for each input source so that you have the opportunity to customize each source to your specific listening requirements. However, once done, they need not be changed again unless your system components have changed.

When using the full-OSD system to make the setup adjustments, press the so that the The cursor will be next to the line. Press the Set Button pœand the first page of the

When the cursor is at the line, you are able to select an alternative to the default input setting for the video input associated with any source. For the Video 1 and Video 4 inputs, the factory default of

AUTO will select either composite or S-

video, depending on which has an active signal. For the Video 2, Video 3 and DVD inputs, the setting will normally select the default component input, but if it is not in use, the system will revert to a composite or S-video output if either one is active.

To have the AVR always look to a specific source connection when an input is selected, make certain that the on-screen cursor is pointing to the

• A standard-definition (480i) analog signal (composite, S-video or component) will be converted so that it is available as an HDMI signal at its input resolution, as well as at the standard composite, S-video or component analog video outputs. The signal will also be available at the record outputs.

• An analog component high-definition signal will be output at its input resolution through the HDMI outputs and as an analog component signal, but not through the analog composite or S-video monitor or record outputs.

• HDMI input signals, regardless of their resolution, will be output through the HDMI outputs only.

The

BYPASS setting will not apply any video

conversion to the incoming video signal, but it will output it in one of the following ways, depending on the input source.

• Analog signals (composite, S-video or component) will output only in the resolution and format that matches the input for both the main “Monitor” connection as well as for the record outputs.

• HDMI input signals, regardless of their resolution, will be output through the HDMI outputs only.

⁄/¤ Navigation

to enter a setting that delays the audio output slightly behind the video so that the loss of lip sync that may occur due to digital video processing in the transmission of a program, in the playback unit or in the display is corrected. This lack of lip sync is not a fault of the sources; rather, it is a by-product of video signal processing. In most cases, we recommend that the delay adjustment be made using the direct-access controls on the remote so that you may more accurately adjust the delay while viewing the on-screen image, following the instructions shown on page 32, but you may also make it here using the menu system. As the amount of delay needed may vary from one source to another, we strongly recommend that you adjust it for each input.

•

DIMENSION: This setting alters the perceived depth of the surround field by creating a shallower presentation that appears to move sounds toward the front of the room, or a deeper presentation that appears to move the center of the sound field toward the back of the room. The setting of “O” is a neutral default, with the range of adjustment shown as “R-3” for a deeper, rear-oriented sound to “F-3” for a shallower, front-oriented sound.

•

PANORAMA: Switch this setting to ON to add an enveloping presentation that increases the perception of sound along the sides of the room.

Using EzSet/EQ

The AVR 645 uses Harman Kardon’s EzSet/EQ technology to automatically configure your system to deliver the best possible performance based on your specific speaker selection, where the speakers are placed in the room and the acoustic influences in your listening room. By using a series of test signals and the processing power of the Texas Instruments

™

DA 610 digital signal processor, EzSet/EQ eliminates the need for manual adjustment of speaker “size”, crossover, delay and output level settings while it adds the power of proprietary algorithms and configurable digital filters to deliver optimal sound reproduction.

In addition to making system setup quick and easy, EzSet/EQ is more precise than manual settings. With EzSet/EQ you are able to calibrate your system in a fraction of the time it would take to enter the settings manually, and with results that rival those achieved with

expensive test equipment and time consuming procedures. The end result is a system calibration profile that enables your new receiver to deliver the best possible sound no matter what type of speakers you have or what the properties of your listening room are.

We recommend that you take advantage of the precision of EzSet/EQ to calibrate your system, but if desired you may also make any of the configuration settings manually, or trim the settings provided by EzSet/EQ by following the instructions on pages 30–35.

Before starting the EzSet/EQ process, make certain that you have connected all speakers for your system and that you have both the EzSet/EQ microphone and the extender rod handy. If you have a standard camera tripod, attach the extender rod to the tripod, and then screw the microphone to the top of the rod. Place the tripod at your primary listening position, at least three feet from the nearest hard surface and adjust it so that microphone is at or above ear level. If you do not have a tripod, simply screw the extender rod into the bottom of the EzSet/EQ microphone.

Next, plug the microphone into the

Microphone Jack Panel Control Door

You are now ready to start the EzSet/EQ process by following these steps:

Step 1. Navigate to the EZSET/EQ MAIN menu (Fig. 9) by first pressing the OSD Button

Step 4. The final menu screen before the EzSet/EQ process starts is a warning screen (Figure 11) that serves as a reminder to keep the room as quiet as possible while the system is in use. Extraneous noise of any kind may adversely affect the accuracy of the system’s results. Do not talk while the test tones are circulating, and if possible, turn off any ventilation systems if the noise form the air flow is loud enough for you to hear. Should an outside noise such as a phone ringing occur during the test process, we recommend that you rerun EzSet/EQ. If you do not wish to start the test process at this time, press the

NOTE: Once the EzSet/EQ process starts, the volume control and Standby/Off switches are temporarily disabled while the tests are in progress. Do not adjust the volume or turn the unit off until you see the on-screen message change to indicate that EzSet/EQ is finished.

Figure 11

Step 5. At this point, a series of test tones will circulate among all the speakers in your system. While this is happening, the AVR 645 is reading the signal to determine which speaker positions are active, what type of speaker is present at each active position, what the distance is from the listening position to each speaker, and to begin to build a pro the room’s acoustics on the quality

file of the impact of

of audio reproduction. When the tones stop, the system will pause for as long as a minute while the processor makes its calculations based on the results of the signal measurements. Do not be alarmed if the “WARNING” message remains on the screen after tones stop until a results message is displayed, as shown in Step 6 or 7.

NOTE: While these tests detect whether a speaker is connected to a particular output, they cannot determine whether the speaker is in the correct position. (For example, it can tell whether a speaker is connected to the Surround Right output, but it cannot tell whether the speaker is on the right or left side of your listening room.) For that reason, we strongly recommend that you try to listen carefully to make sure that the test tone circulates in a clockwise rotation, starting with the front left speaker, to the center, to the front right, and so on to the subwoofer. If the tone is heard from a speaker that seems as though it is out of sequence, such as the tone coming from the surround left speaker when the next speaker in the sequence should be the surround right speaker, exit the EzSet/EQ system when the test sequence is completed and use the manual output level tone adjustment process, as outlined on page 33, to determine which, if any, speaker is incorrectly connected.

When the test process stops, you will see a message indicating that the Far Field measurements are complete. If there is an error, follow the instructions in Step 7A or Step 7b.

Step 8. When the Far Field measurements are completed, the next step is to take three Near Field measurements, one at each front speaker position. These measurements enable EzSet/EQ to produce the most accurate settings for high-frequency equalization. The Near Field measurements are similar to the Far Field tests, except that the system will “listen” to only one speaker at a time, rather than sending the test signals to all speakers in rotation.

When the measurements have been successfully completed, your system is ready for use. Thanks to EzSet/EQ, the settings for speaker “size,” speaker crossover, channel output and individual channel delay time have been automatically set and require no further adjustment. In addition, EzSet/EQ also performs a complete room equalization that tailors the system’s performance for the best possible sound with your combination of speakers, speaker placement and room acoustics. The next few pages in this manual detail the procedure for manually entering system data, but unless you want to view the setting information and make an adjustment, you are now ready to enjoy the finest in home theater and music reproduction. Go to page 36 for complete information on operating your AVR 645.

Manual Setup

In most cases it is simpler, easier and more accurate to let EzSet/EQ take care of entering the system parameters for speaker “size”, speaker crossover, channel output and individual channel delay time. However, if you feel that your listening room or system components are best suited to manual entry of these settings, the AVR 645 also allows you to enter or trim any of these system parameters. Even if you do make the settings manually, we recommend that you run the EzSet/EQ tests first so that a baseline setting is established, and then make your adjustments from there. Note that once EzSet/EQ has been run you do not need to adjust all system settings, only those that you want to change.

Speaker Size Menu

Although most listeners will prefer to take advantage of the accuracy and speed of EzSet/EQ to make all of the necessary speaker adjustments, advanced users may wish to experiment with how different combinations of settings sound in their home theater environment or to use settings other than those calculated by EzSet/EQ, to accommodate personal listening preferences.

The menu system used in your AVR 645 differs somewhat from conventional speaker setup menus in that it consolidates the speaker “size” and crossover into one convenient menu. Even if you are familiar with making these adjustments, it is strongly recommended that you read the following section of this manual.

On the

SPEAKER SIZE menu (Figure 19) you

have the option to change the type of speaker configured for each of the four position groups, to change the crossover setting for any one of those speakers, to adjust the setting point for the low-pass filter that determines which frequencies are sent to the subwoofer for low-frequency effects (LFE) signals, to change the subwoofer bass redirection mode when the Front Left/Right speakers are set to Large and to change the setting for the subwoofer size. If, as recommended, you have first run the EzSet/EQ system, as shown on pages 27–30, the settings established by EzSet/EQ will be displayed as a starting point for any manual adjustments. You may reestablish those settings at any time during an adjustment on this by pressing the

⁄/¤ Navigation Button

until the cursor is on the EZSET SETTINGS line of the menu and then pressing the ‹/›

Navigation Button n©so that ON is high-

lighted in reverse video. Note, however, that once this is done, any manual adjustments made will be lost and must be reentered.

Speaker Size

At each of the four speaker group positions, you have the ability to select the speaker “size” and, when a “Small” speaker is selected, the frequency below which low-frequency information is sent to the subwoofer, as opposed to the speakers for the channel being adjusted. For that reason, before making the adjustments on the

FRONT L/R, CENTER,

SIDE SURR and BACK SURR menu lines,

it is important to know the frequency range for the speaker. This information is typically found in the “Specifications” section of the speaker’s owner’s manual. If you cannot find the specification for the lowest frequency the speaker can handle, start with the settings entered by running EzSet/EQ and then try one setting above or below the existing entry. We do not recommend changing the crossover point more than

that due to the possible impact that will have on the speaker’s performance. If you do not have access to the owner’s manual for a particular speaker, you should be able to obtain the needed information from the Web site or customer service department of the speaker’s manufacturer.

The warning message will remain for four seconds and then the

SPEAKER SIZE menu will return to

the screen. At this point you may change the settings to the “size” or crossover for any of the four speaker positions using the

Navigation Buttons n©as

shown above. The information below details the settings available for each of the speaker configurations.

At each of the four speaker position lines, you have the option to set the speaker size and crossover. Note that the “size” does not refer to the speaker’s actual physical size, but rather to the ability of the speaker to reproduce low-frequency information. If your speakers at any position are traditional full-range models capable of handling the full audio spectrum, select LARGE. These speakers are called “large” since the low-frequency drivers required to play bass without strain or distortion are typically eight to fifteen inches in diameter, in turn making the speaker cabinet larger than those with small (or no) low-frequency drivers. When the speakers at a particular position are smaller frequency-limited speakers that do not have the ability to properly reproduce low-frequency sounds, select SMALL.

At all speaker positions except for the front left/right speakers, you may also select

NONE. This setting

tells the system that no speakers are present at that position, allowing the AVR to select the correct surround modes that are compatible with the number of speakers installed. For example, in order to use the Dolby Digital EX, Dolby Pro Logic IIx, DTS-ES, Logic 7/7channel and “7 Stereo” modes, you must have either LARGE or SMALL entered as the setting for the

BACK SURR channels.

When

LARGE is selected for any channel, a full-

range signal will be sent to the speaker outputs for that channel. For all speaker positions except the front left/right, when

LARGE is chosen, no derived

sound will be sent to the subwoofer output, although in all cases the special low-frequency effects (LFE) signals available on 5.1 or 6.1 digital programs will always be sent to the subwoofer output.

When

SMALL is selected for any channel, you may

also enter a setting for the crossover frequency at which sound is divided between the frequency above which sound is sent to the channel’s speakers and below which sound is sent to the subwoofer. When configuring a “small” speaker, choose the setting that has the frequency closest to that of the lowest frequency the speakers in question are capable of handling. If one of the six available crossover points does not match, select the one that is above, but closest to, the speaker’s low-frequency limit.

When there are no speakers available at a specific position, select

NONE. When this option is chosen

for the Center or Side Surround speakers, the sound that would normally be sent to these channels will be split between the front left and right speakers. Note that when your system does not include Center or Surround speakers, the use of Dolby Virtual Speaker as a surround mode may provide a sound field that simulates the presence of these speakers. (See the appendix for more information on the Dolby Virtual Speaker mode.)

Note that when

NONE is selected for the Back

Surround speakers, the 6.1/7.1 channel surround modes are not available. When this is the case for your system, you may wish to take advantage of the availability of the unused amplifier channel pair to power a second set of speakers in another room. (See page 46 for more information on amplifier configuration.)

Once any desired changes have been made to the speaker size and/or crossover, press the

⁄/¤

Navigation Button n©to move the cursor to

any other line on this menu to make a setting change, or go to the

BACK TO MANUAL SETUP

menu and then press the Set Button pœto continue with overall configuration.

Delay Settings

Due to the different distances between the listening position and each speaker position, the amount of time it takes for sound to reach your ears from each channel is different. You may compensate for this difference through the use of the delay settings to adjust the timing for the speaker placement and acoustic conditions in your listening room or home theater.

In most cases, the settings established by EzSet/EQ are accurate to under a foot, but the placement of the microphone and other factors may influence the setting. Should you wish to manually adjust the channel delay times, follow the instructions shown below. Whenever adjustments to the delay settings are made remember that the distance settings need not be accurate to the inch, as the system is designed to accommodate a typical listening area rather han the precise measurement from the speakers to a specific “sweet spot” position.

In addition to providing delaying adjustments for each individual speaker position, the AVR 645 allows you to adjust the delay for the combined output of all speakers as a group. This feature is called A/V Sync Delay; it allows you to compensate for delays to the video image that may be caused by the processing in products such as digital video displays, video scalers, digital cable or satellite systems, or personal video recorders. With proper adjustment of the setting for A/V Sync Delay, you can eliminate the loss of lip sync that may be caused by digital video applications.

Output Level Adjustment

Output level adjustment is a key part of the configuration of any surround sound product. It is particularly important for a digital receiver such as the AVR 645, as correct outputs ensure that you hear soundtracks with the proper directionality and intensity.

In most cases, you will not need to make any adjustments to the output level, as the settings made by running EzSet/EQ are as accurate as those made manually. However, you are able to use the CHANNEL ADJUST menu to trim the settings to suit your personal preferences or to configure the system so that the output settings are different from one input source to another.

The ability to make individual output level adjustments on a per-input basis is useful for listeners who may prefer different settings for the subwoofer or an individual channel group such as the front speakers when playing musical selections via the CD input as opposed to the movie soundtracks more frequently used with the DVD input. This menu also allows you to adjust the output levels using external sources such as a test disc or other program material that you use as a standard, rather than the system’s test tone.

IMPORTANT NOTE: Listeners are often confused about the operation of the surround channels. While some assume that sound should always be coming from each speaker, most of the time there will be little or no sound in the surround channels. This is because they are only used when a movie director or sound mixer specifically places sound there to create ambience, a special effect or to continue action from the front of the room to the rear. When the output levels are properly set, it is normal for surround speakers to operate only occasionally. Artificially increasing the volume to the rear speakers may destroy the illusion of an enveloping sound field that duplicates the way you hear sound in a movie theater or concert hall, even when making manual adjustments.

Before beginning the output level adjustment process, make certain that all speaker connections have been properly made. The system volume should be set to the level that you will use during a typical listening session. We recommend that EzSet/EQ be used when the AVR is first installed to establish the initial level settings.

In addition to having the test tone circulate automatically, you may also turn the test tone on, but advance it from one channel to the next manually. This allows you to make calibration adjustments, but to have more control over the way the test tone is moved among the channels.

Surround Mode Selection

One of the most important features of the AVR 645 is its ability to reproduce a full multichannel surround sound field from digital sources, analog matrix surround-encoded programs and standard stereo programs.

Selection of a surround mode is based on personal taste, as well as the type of program source material being used. For example, motion pictures or TV programs bearing the logo of one of the major surroundencoding processes, such as Dolby Surround or DTS Stereo may be played in either the Dolby Digital, Dolby Pro Logic II Cinema, DTS Neo:6 Cinema, or Logic 7 Cinema surround modes, depending on the source material.

NOTE: Once a program has been encoded with matrix surround information, it retains the surround information as long as the program is broadcast in stereo. Thus, movies with surround sound may be decoded via any of the analog surround modes such as Dolby Pro Logic II Cinema, Logic 7 Cinema or DTS Neo:6 Cinema, when they are broadcast via conventional TV stations, cable, pay-TV and satellite transmission. In addition, a growing number of made-for-TV programs, sports broadcasts, radio dramas and music CDs are also produced in surround sound. You may view a list of these programs at the Dolby Laboratories Web site at www.dolby.com.

Even when a program is not listed as carrying intentional surround information, you may find that the Dolby Pro Logic II, Dolby Pro Logic IIx, Logic 7 or DTS Neo:6, and the Hall or Theater modes often deliver enveloping surround presentations through the use of the natural information present in all stereo recordings.

Surround modes may be changed at any time by using either the front panel or remote control. To

select a new surround mode from the front panel, first press the

Surround Mode Group Selector Button

2 until the desired major surround mode group such as Dolby, DTS or Logic 7 is selected. Next, press the Surround Mode Selector Button 3 to choose the specific individual surround mode.

For more information on selecting digital sources, see the Digital Audio Playback section below.

When the 6-channel/8-channel direct inputs are in use, there is no surround processing, as these inputs take the analog output signals from an external source device and carry them straight through to the volume control without any further digital processing.

Digital Audio Playback

Digital audio is a major advancement over older analog surround processing systems. It delivers up to six discrete channels, and each channel reproduces a full-frequency range (20Hz to 20kHz) and offers dramatically improved dynamic range and significant improvements to signal-to-noise ratios. In addition, digital systems have the capability to deliver an additional channel that is specifically devoted to low-frequency information. This is

OPERATION 37OPERATION 37

OPERATION

the “.1” channel referred to when you see these systems described as “5.1,” “6.1” or “7.1.” The bass channel is separate from the other channels, but since it is intentionally bandwidth-limited, sound designers have given it that unique designation. When a digital soundtrack is playing, the number of channels available will vary according to the way in which the program was recorded. Although most movies recorded with digital sound have 5.1 soundtracks, some have 6.1 or 7.1 sound, while others retain the original two-channel or even monaural sound. When the program source is a broadcast, cable or satellite delivered digital program, only one type of soundtrack may be delivered at a time, while optical sources such as DVD may provide more than one audio option. In either case, the decision of what type of sound track and how many channels to offer is up to the program’s producer. With the AVR 645 you are able to not only play back the original compatible digital format, but using the processing power of the Texas Instruments DSP processor, it is possible to decode the basic digital track for 2.0 or

5.1 sound and then select an additional “post-processing” mode to deliver additional channels.

Dolby Digital

Dolby Digital is the default format for DVD discs and for the (ATSC) high-definition system used in the United States and Canada. It is also used by the digital satellite program services and is available on most digital cable set-top boxes. When the AVR 645 is connected to a blue-laser-based high-definition optical disc player via an HDMI, coaxial or optical digital connection, the soundtrack from the player may be available in the standard Dolby Digital or DTS format, so that it may be decoded by the AVR.

An optional, external RF demodulator is required to use the AVR 645 to listen to the Dolby Digital soundtracks available on laser discs. Connect the RF output of the LD player to the demodulator and then connect the digital output of the demodulator to the or Coaxial Inputs KMab of the AVR 645. A demodulator is not required for use with high-definition optical disc or DVD players, or with DTS-encoded laser discs.

In order to provide maximum playback compatibility with DVDs, the AVR 645 receiver will always default first to the playback mode embedded in a disc’s digital “flag” information. For Dolby Digital discs, the following playback modes are initially selected after the AVR locks on to the incoming digital audio data stream:

• When a Dolby Digital 5.1 data stream is detected, the choice of which surround mode is activated is determined by the setting on the

SURR

line of the SURROUND CONFIG

menu (Figure 21), as shown on page 26.

Optical

DEFAULT

• When a disc with the Dolby Digital EX flag is played, your system will automatically switch to the EX mode when seven main speakers are available.

• When a disc with 2.0 Dolby Digital data is detected, the default mode is Dolby Digital with Pro Logic II postprocessing when you have a 5.1 speaker system, or Dolby Digital with Dolby Pro Logic IIx postprocessing when you have a 7.1 speaker system.

• Depending on the number of speaker channels available in your system, once the AVR locks on to the digital signal, you may select any surround mode or postprocessing option that is available, based on the incoming data stream’s possible restrictions and the number of speakers in your system. For example, when a 5.1 or 2.0 audio stream is in use, you may select alternate postprocessing such as Logic 7/7.1-channel Movie mode postprocessing to create the rear surrounds in 7.1 speaker systems.

DTS

DTS is another digital audio system that is capable of delivering 5.1 or 6.1 discrete or matrix sound field reproduction. Although both DTS and Dolby Digital are digital, they use different methods of encoding the signals, and thus they require different decoding circuits to convert the digital signals back to analog.

DTS-encoded soundtracks are available on select DVD and LD discs, as well as on special audio-only DTS discs. You may use any LD or CD player equipped with a digital output to play DTS-encoded discs with the AVR 645. All that is required is to connect the player’s output to either an on the rear panel ab or front panel KM.

In order to listen to DVDs encoded with DTS soundtracks, the DVD player must be compatible with the DTS signal, which is indicated by a DTS logo on the player’s front panel. Early DVD players may not be able to play DTS-encoded DVDs. If you are in doubt as to the capability of your DVD player to handle DTS discs, consult the player’s owner’s manual.

When the AVR 645 is connected to a blue-laserbased high-definition optical disc player via an HDMI, coaxial or optical digital connection, the soundtrack from the player is also available in the standard DTS format so that it may be decoded by the AVR.

NOTE:

• Some DVD players have a default setting that does

not pass through the DTS signal. Before playing DVDs with a DTS soundtrack, make certain that the

settings in your DVD player have been properly

adjusted

so that DTS audio is passed through. Consult the owner’s manual for your DVD player for more information on making these settings.

Optical or Coaxial Input

• When selecting surround modes, any mode where the setting in its mode group (Dolby, DTS, Logic 7, PCM, etc.) has been set to SURROUND CONFIG menus will not appear. You may change the settings in this list at any time by following the instructions on page 26.

Selecting a Digital Source

To utilize either digital mode, you must have properly connected a digital source to the AVR 645. Connect the digital outputs from DVD players, HDTV receivers, satellite systems or CD players to the

Inputs

KMab. In order to provide a backup signal

and a source for analog stereo recording, the analog outputs provided on digital source equipment should also be connected to their appropriate inputs on the AVR 645 rear panel (e.g., connect the analog stereo audio output from a DVD to the on the rear panel when you connect the source’s digital outputs).

If you have not already configured an input for a digital source using the on-screen menus, as shown on page 24, first select the input using the remote or front-panel controls, as outlined in this manual. Next, press the

Digital Select ButtonE, then press the

When both a digital and an analog connection are made between a source device and the AVR, the digital input is the default. If the digital stream is not present or is interrupted, the unit will automatically switch over to the analog inputs for the selected source.

If you wish to disable the auto-polling feature, you may do so by following the instructions shown for the IN/OUT SETUP menu (Figure 2), as shown on page 24

Digital Bitstream and Surround Mode Indications

When a digital source is playing, the AVR 645 senses the type of bitstream data that is present, and automatically selects the proper surround mode. For example, DTS bitstreams will cause the unit to switch to DTS decoding, and Dolby Digital bitstreams will enable Dolby Digital decoding. When the unit senses PCM data from CDs or LDs, you may select any of the standard Dolby or DTS surround modes or Logic 7. Since the range of available surround modes is dependent on the type of digital data that is present, the AVR 645 shows you what type of signal is present to help you understand the choice of modes.

When a digital source is first detected, the AVR 645 will display a message to indicate the type of bitstream being received. It will remain in the

Lower Display

Line $ for about 5 seconds before that portion of the

display returns to the normal surround mode indication.

For Dolby Digital and DTS sources, a numerical indication (such as

3/2/2.1) will appear, showing the

number of channels present in the data.

The first number in the display message indicates how many discrete front-channel signals are present.

• A “3” tells you that separate front left, center and front right signals are available. This will be displayed for Dolby Digital 5.1, Dolby Digital EX and DTS 5.1 or DTS-EX programs.

• A “2” tells you that separate front left and right signals are available, but there is no discrete center channel signal. This will be displayed for Dolby Digital bitstreams that have stereo program material.

• A “1” tells you that there is only a mono channel available in the Dolby Digital bitstream.

The middle number in the display message indicates how many discrete surround channel signals are present.

• A “3” tells you that separate, discrete left surround, center surround and right surround signals are present. This is available only on discs with DTS-ES digital audio.

• A “2” tells you that separate surround left and right signals are available. This will be displayed for Dolby Digital 5.1 and DTS 5.1 programs.

• A “1” tells you that there is only a single, surroundencoded surround channel. This will appear for Dolby Digital bitstreams that have matrix encoding.

• A “0” indicates that there is no surround channel information. This will be displayed for two-channel stereo programs.

The last number indicates whether there is a discrete low-frequency effects (LFE) channel. This is the “.1” in the common abbreviation of “5.1” sound and it is a special channel that contains only bass frequencies.

• A “.1” tells you that an LFE channel is present. This will be displayed for Dolby Digital 5.1 and DTS 5.1 programs, as available.

• A “0” indicates that there is no LFE channel information available. However, even when there is no dedicated LFE channel, low-frequency sound will be present at the subwoofer output when the speaker configuration is set to show the presence of a subwoofer.

• The information on the right side of the display will tell you whether the digital audio data contains a

special flag signal that will automatically activate the appropriate 6.1 or 7.1 mode. This will be shown as EX-ON or EX-OFF for Dolby Digital bitstreams and ES-ON or ES-OFF for DTS bitstreams.

When a 2.0 or 5.1 digital source is playing on a system configured for 5.1 operation, you may use Dolby Digital EX, DTS-ES, Logic 7/7.1 or Dolby Pro Logic IIx to add rear channels for full 7.1 sound fields. Note, however, that the availability of specific modes for postprocessing is dependent on the format of the incoming source material. While some combinations (e.g., a Dolby Digital or DTS 5.1 source with Logic 7/

7.1 or Dolby Pro Logic IIx postprocessing) are allowable, others (e.g., a Dolby Digital 5.1 source with DTS Neo:6) are not. If you wish to add surround back channels to a 2.0 or 5.1 source, we recommend that you experiment with the various options to see which may be available and which are best suited to your taste and listening environment.

It is always a good idea to check the readout for the channel data to make certain that it matches the audio logo information shown on the back of a DVD package. In some cases, you will see an indication for “2/0/0” even when the disc contains a full 5.1, or 3/2/.1, signal. When this happens, check the audio output settings for your DVD player or the audio menu selections for the specific disc being played to make certain that the player is sending the correct signal to the AVR.

PCM Playback

PCM is the abbreviation for Pulse Code Modulation, the digital signal format used for standard CD playback, and other non-Dolby Digital and non-DTS digital sources such as MiniDisc. When a detected, the

Lower Display Line $ will briefly

show a message with the letters PCM, in addition to a readout of the sampling frequency of the digital signal.

In most cases, this will be

PCM 44.1kHz or

PCM 48kHz, though in the case of specially

mastered, high-resolution audio discs, you will see a PCM 96kHz indication. Note that the sampling rate displayed is that of the incoming digital signal, and not the upsampled rate that may be applied to PCM sources when Dolby Pro Logic or Dolby Pro Logic II processing is applied, as shown on page 26.

During PCM playback, you may select any surround mode except Dolby Digital or DTS/DTS-ES mode.

USB Playback

The AVR 645 is among the very few A/V receivers capable of direct connection to a computer for audio playback. Once the AVR is connected, audio streams and playback are possible through your AVR, with all the power and performance of the high-current amplifi-

er, your own speakers, and the enhanced multichannel playback made possible through the use of Logic 7, Dolby Pro Logic II/IIx or DTS Neo:6 processing.

The AVR 645’s USB connectivity may be used with PC-compatible computers running either Microsoft

Windows®2000 with Service Pack 4 or higher installed, or Windows XP or Windows XP Media Center Edition with Service Pack 1 or higher installed. Connect one of the available USB ports on your computer or a USB hub to the

USB Port W on the AVR

using a cable with a standard USB plug on one side and a USB “Mini B” plug on the other side. You may use an optional cable available at most electronics and computer stores for this purpose.

In addition, you will need to have a media player installed on the computer. The AVR 645 has been tested for operation with Windows Media Version 8.0 and above, but it is also compatible with many other popular players such as iTunes

Player

, Winamp and RealPlayer.®In most cases, it is best to always make certain that you have the latest version of the player installed to ensure the best compatibility.

When the connection between a computer and the AVR is made for the first time, or if the USB connection is plugged into a different USB port on a computer

or hub that has not been previously connected to the AVR, you will see a series of pop-up messages from Windows to indicate that the computer is configuring itself for the new device. Since the AVR provides a number of different functions, you may see the “Found New Hardware” message up to four times, one each for “A/V Receiver,” “Compatible Device,” “Audio Receiver” and “Human Interface Device.” When all messages have appeared and then cleared the screen, you are almost ready to begin.

Before selecting the USB input, first make certain that one of the media players listed above has been opened on the computer. Then you may select the USB input in any of the following ways:

• To select USB as a source from the front panel,

press the I USB appears as the input name in the

playback, as well as move to the next track. Activity of the Transport buttons may vary from one media player to another, but at the very least you will be able to use the Play and Stop buttons.

Once playback is started, the audio from a USB source is treated the same as any other two-channel audio source, and you may apply any of the appropriate surround processing modes. When playing back audio from a computer via the USB connection, the internal speakers in a laptop computer are often muted.

Speaker/Channel Indicators

In addition to the bitstream indicators, the AVR 645 features a set of unique channel-input indicators that tell you how many channels of digital information are being received and/or whether the digital signal is interrupted (Figure 23).

Figure 23

The letters inside the boxes tell you which channels are receiving an input signal. Since conventional analog audio is only two channels, the “L” and “R” letters will light with any analog source. When a digital source is in use, you will see letters displayed that correspond to the number of channels in the incoming data stream, which may be just the L and R for two-channel PCM or 2.0 Dolby Digital material. When a 5.1 signal is being received, the L/C/R/SL/SR indicators will light, with the LFE indication also being shown when an LFE signal is present. All seven indicators, including the SBL/SBR letters, will light for a 7.1 signal, and a horizontal line is shown to connect the SBL/SBR indicators when a 6.1 source is in use.

It is important to note that although Dolby Digital, for example, is referred to as a “5.1” system, not all Dolby Digital DVDs or programs are encoded for 5.1. Thus, it is sometimes normal for a DVD with a Dolby Digital soundtrack to trigger only the “L” and “R” indicators.

NOTE: Many DVD discs are recorded with both “5.1” and “2.0” versions of the same soundtrack. When playing a DVD, always be certain to check the type of material on the disc. Most discs show this information in the form of a listing or icon on the back of the disc jacket. When a disc does offer multiple soundtrack choices, you may have to make some adjustments to your DVD player (usually with the “Audio Select” button or in a menu screen on the disc) to send a full 5.1 feed to the AVR 645. It is also possible for the type of signal feed to change during the course of a DVD’s

playback. In some cases, the previews of special material will only be recorded in 2.0 audio, while the main feature is available in 5.1 audio. The AVR 645 will automatically sense changes to the bitstream and channel count and reflect them in these indicators.

The letters used by the

Indicators

@ will flash to indicate when a bitstream

Speaker/Channel Input

has been interrupted. This will happen when a digital input source is selected before the playback starts, or when a digital source such as a DVD is paused. The flashing indicators remind you that the playback has stopped due to the absence of a digital signal and not through any fault of the AVR 645. This is normal, and the digital playback will resume once the playback is started again.

The boxes around the channel indication letters are used to show which speakers are configured in your system. A small box around the letter indicates that a “Small” speaker has been assigned to that position, while a larger, double box indicates a “Large” speaker assignment.

Note that in some cases, such as an analog stereo or

2.0 digital sources you will see empty speaker position boxes, which indicates that the speaker is active and will receive sound, but that there is no discrete signal for that channel. In other cases you may see letters with no speaker boxes. This indicates that there is a discrete signal for that channel, but due to the mode in use (e.g., Dolby VS with a 5.1 source) there is no signal being sent to the channel.

Night Mode

A special feature of Dolby Digital is the Night mode, which enables specially encoded Dolby Digital input sources to be played back with full digital intelligibility while reducing the minimum peak level by 1/4 to 1/3. This prevents abruptly loud transitions from disturbing others, without reducing the impact of the digital source. The Night mode is available only when Dolby Digital signals with special data are being played.

The Night mode may be engaged at any time when a Dolby Digital source is playing by pressing the

Mode Button

.Each press of the button will

change the Night mode setting, as shown in the lower third of the on-screen display (except when 720p or 1080i sources are in use). To turn the Night mode off, press the button as described, until

D-RANGE

The Night mode may also be selected to always be on at either level of compression using the options in the DOLBY SURROUND menu. See page 27 for information on using the menus to set this option.

IMPORTANT NOTES ON DIGITAL PLAYBACK:

• When playing DVDs, please note that even when you have selected a specific digital audio format for playback, an individual disc may change formats or the

number of available channels during playback. For example, even if you select a DTS mode for the movie, you may see Dolby Digital in use when the trailers, menus or copyright warnings are playing. This is not a fault with either the AVR or your DVD player, as both are responding to the way the disc was created.

• When viewing digital television signals, note that the number of audio channels available may vary during the course of a program, depending on the content. For example, while a sports event may have 5.1 sound, the commercials or local station content may be in 2.0. In addition, not all local stations are currently equipped for carrying the 5.1 digital audio signals. This may mean that even though the actual program is produced with 5.1, it may be transmitted in a 2.0 configuration in some areas. Your AVR will automatically change to react to the proper type of audio stream if it is changed by the broadcast station.

• Although the AVR 645 will decode virtually all current DVD movies, CDs and HDTV sources, it is possible that some future digital sources may not be compatible with the AVR 645.

• Not all digitally encoded programs contain full 5.1or 6.1-channel audio. Consult the program guide that accompanies the DVD or laser disc to determine which type of audio has been recorded on the disc. The AVR 645 will automatically sense the type of digital surround encoding used and adjust to accommodate it.

• When a digital source is playing, you may not be able to select some of the analog surround modes such as Dolby Pro Logic II, Dolby Pro Logic IIx, Stereo, Hall, Theater or Logic 7.

• When a Dolby Digital or DTS source is playing, it is not possible to make an analog recording using the

XM Radio Operation

XM Radio is a satellite-delivered service that offers hundreds of program channels, as well as local traffic and weather information for select cities. The AVR 645 is “XM Ready,” which means that the unit is able to receive the XM service when an optional XM Connect and Play or Passport module is connected and the service activated. You may purchase the antenna module needed for XM Radio from many electronics or online retailers, or directly from XM Radio through the “Home Receivers” section of the XM Radio Store at www.xmradio.com.

Once you have purchased the XM module, follow the instructions accompanying it to activate the XM Service. Connect the plug on the XM module to the XM Ready Module Input V on the rear panel of the AVR 645. For best results, point the antenna module out a window, again, following the instructions packed with the XM product. If a window view is not available for the antenna, XM Radio operates a series of terrestrial repeater stations that may be able to provide reception, though this service is not available everywhere.

IMPORTANT NOTE: XM Radio requires both the optional, external antenna module and a subscription to the XM Radio service. Antenna and service sold separately; XM Radio is not available in Alaska or Hawaii.

If you need to view the antenna module’s number, connect it to the AVR and then follow one of the steps shown below to select XM Radio as the input source. Tune to “000” to get a readout of the number.

Once you have an activated module connected, follow one of these steps to select XM Radio as your system’s audio source:

• From the front panel, press the

Transport Controls

While using XM Radio is similar in many ways to AM/FM terrestrial radio, the wide range of program choices available, as well as the ability of the XM service to add special data and information tags into the digital audio data stream, means that some of the front-panel and remote controls traditionally used for tuner operation have different functions with XM Radio.

• When XM Radio is the AVR’s source, the channel number will appear in the along with an indication of the Preset number, if any, and a series of bars at the far right end of the display. These bars (not shown in the semi-OSD message), show the current signal strength similar to the signal strength displays on a cellular phone.

Recording

In normal operation, the audio or video source selected for listening through the AVR 645 is sent to the record outputs. This means that any program you are watching or listening to may be recorded simply by placing machines connected to the outputs for

Tape Outputs £ or Video 1 Audio and Video Outputs

Sg in the record mode.

When a digital audio recorder is connected to the Digital Audio Outputs XYM, you are able to record the digital signal using a CD-R, MiniDisc or other digital recording system.

NOTES:

• The digital outputs are active only when a digital signal is present, and they do not convert an analog input to a digital signal, or change the format of the digital signal. In addition, the digital recorder must be compatible with the output signal. For example, the PCM digital input from a CD player may be recorded on a CD-R or MiniDisc, but Dolby Digital or DTS signals may not.

• The

Front-Panel Video 4 N and Coaxial 4 M

jacks may be configured for use as outputs, allowing connection to a recorder, when the steps shown in the section below are followed.

• Please make certain that you are aware of any copyright restrictions on any material you copy. Unauthorized duplication of copyrighted materials is prohibited by federal law.

Front-Panel Connections

In addition to the rear-panel digital and analog outputs, the AVR 645 offers Harman Kardon’s exclusive configurable front-panel output-jack feature. For easy connection of portable devices, you may switch the frontpanel

The AVR 645 is fully equipped to operate as the control center for a complete multiroom system that is capable of sending one audio source to a second zone in the house while a separate source is listened to in the main room. In addition to providing for control over the selection of the remote source and its volume, the AVR 645 offers a comprehensive range of options for powering the speakers in the second zone.

• Using the line-level the selected source may be fed to optional, external power amplifiers that may be matched to the specifics of the installation.

• When the main room system is configured for 5.1 operation, the Surround Back Left/Right amplifier channels may be used to power the remote zone so that no additional amplifiers are required.

• Using built-in A-BUS/ A-BUS modules may be connected to the AVR 645 via a single Category 5/5e or higher cable, so that remote zone speakers may be powered directly from the A-BUS module without the need for additional power, IR sensor or volume control wires to be run to the second zone.

In addition, the AVR 645 includes a remote IR sensor input so that remote control commands from the ZR 10 remote included with the unit may be transmitted to the unit, while standard IR input/output jacks allow the remote zone’s commands to be sent to compatible IR-controlled source devices.

Installation

Although simple remote room systems may be installed by the average do-it-yourself hobbyist, the complexity of your multizone/multiroom system involves running wires inside of walls where the services

of a specially trained installer may be required. Regardless of who does the work, please remember that local building codes may govern in-wall electrical work, including proper specification of any wiring used and the way in which it is connected. You are responsible for making certain that all multiroom installation work is done properly and in compliance with all applicable codes and regulations.

For standard installations, follow the instructions shown on page 19 for the connection of speaker wire and IR remote wiring to the AVR 645.

For installations where the Surround Back Left/Right amplifier channels are used to power the remote zone, make certain that the system is configured for that type of operation, as shown on this page.

For installations where A-BUS modules are used, follow the instructions provided with the A-BUS remote modules or keypads. Additional information will also be made available through the Harman Kardon Web site at www.harmankardon.com.

RS-232 Control

The AVR 645 provides the capability for full bidirectional remote control from compatible computers or specialized remote control systems. RS-232 programming requires specialized programming knowledge and for that reason we recommend that it only be done by qualified professionals. For more information on using the RS-232 port for remote control, visit the Harman Kardon Web site at www.harmankardon.com or contact our customer service department.

Surround Channel Amplifier Assignment

The AVR 645 is equipped with seven full-power amplifier channels to allow for complete 7.1-channel operation. However, if your system is only configured for 5.1 channels in the main listening room, you may take advantage of the “extra” two channels by using them to power speakers placed in a second-zone location. This enables you to use the multiroom capabilities of the AVR 645 without the cost of an additional, external power amplifier.

To change the setting so that the Surround Back amplifiers are fed by the source selected through the Multiroom system rather than the SBL/SBR channels of the main room, make certain that the MULTI-ROOM SETUP menu (Figure 25) is on the screen; then press the

The AVR 645 remote is factory-programmed for all functions needed to operate the unit. In addition, it is also preprogrammed to operate most recent Harman Kardon DVD players and changers, CD players and changers, CD recorders and cassette decks. The codes for other brand devices may be programmed into the AVR 645 remote using its extensive library of remote codes or a head-to-head learning process for codes not in the internal library.

As an alternative to the AVR remote, consider purchasing Harman Kardon’s TC 30 activity-based remote, which uses Web setup wizards to custom configure your remote. For more information visit www.harmankardon.com.

Thanks to the remote’s advanced technology and two-line LCD, it is no longer necessary to look up cumbersome codes when programming the remote; following the steps outlined below, you simply search for the brand name from the remote’s memory. We recommend that you first try the preprogrammed code entry method. If that procedure is not successful, then try the code-learning method.

Preprogrammed Code Entry

The easiest way to program the remote for operation with a source device from another brand is to follow these steps:

1. Turn on the power to the device you wish to program into the AVR remote. This is important, as in a later step you will need to see whether the device turns off to determine whether the remote has been programmed for the proper remote codes.

2. Press and hold the about 3 seconds while the message shown in Figure 26 appears in the remote’s

NOTE: The codes for hard-drive recorder products (PVR) such as TiVo

and ReplayTV®are programmed by selecting VCR as the device. For satellite-based TiVo products, check under the brand name of the product.

5. At the next menu screen on the remote (Figure

29), press the

Set Button F to enter the

Manual mode, which means that you will select the brand name of the device from the list programmed into the remote’s memory.

Figure 29

6. The next menu screen on the remote (Figure 30) will show the start of the list of available brands. Press the

and skip to the instructions shown on page 49 for the “Automatic” method of programming the remote. If desired, or if the codes for your brand are not part of the remote’s library at all, you may still use the remote to program most infrared-controlled products by “learning” the commands from the product’s original remote into the AVR remote. The instructions for Learning Commands are on page 49.

7. The next step is important, as it determines which codes will operate the source device or display. Point the AVR remote at the device being programmed and, following the instructions shown in the remote’s press and release the

9. If the device being programmed into the AVR remote does the

not

turn off after you have pressed

“1” Button , repeat Steps 7 and 8 by

pressing the available numeric keys shown until the device turns off. If the device still does not turn off after all choices have been tried, or if there is only one number key shown as available to try, the code for this specific device is not in the AVR remote library under that brand name. If that is the case, press the

Clear Button j to exit the

manual programming mode. Remember that the codes may still be stored in the AVR remote’s library under another brand, and you can have the remote control search for them by following the instructions below for automatic programming. You may also manually “learn” the codes for most devices into the AVR remote by following the Learning Commands instructions on page 49.

10. When the device being programmed does turn off after a numeric key has been pressed, you must press the

Set Button F within 5 seconds to

enter the setting into the remote’s memory. After you press the LCD will read

11. When the codes are saved, the remote will return to normal operation, and whenever you press the Input Selector Button d that was just programmed, the codes for the new device will be used. If no further buttons are pressed, the remote will revert back to the default setting for AVR commands.

NOTE: Some brands share a common remote control code for “Power Off” for many models. For that reason, it is possible that even though the remote appears to be properly programmed, you may find that some buttons do not appear to issue the correct command. If this is the case, repeat the procedure outlined above,

Automatic Code Entry

In addition to manual code selection using the brand name list, it is also possible to automatically search through all the codes that are stored in the AVR remote’s library to see whether a device will respond even if it is not listed among the brands that appear when you program the remote manually.To automatically search through the codes that are available for a specific device type (e.g., DVD, VCR), follow these steps:

1. Turn on the power to the device you wish to program into the AVR remote. This is important because in a later step you will need to see whether the device turns off to determine whether the remote has been programmed for the proper remote codes.

2. Press and hold the about 3 seconds while the message shown in Figure 26 appears in the remote’s

Input Selector Button d that was just

programmed, the codes for the new device will be used. If no further buttons are pressed, the remote will revert back to the default setting for AVR commands.

Learning Commands

On occasions when the AVR remote does not contain the codes for a particular product’s remote in its builtin library, or when you wish to program a missing or special function into one button of a device, the AVR remote’s learning capability allows you to do that. To teach commands from one product’s remote into the AVR remote:

The AVR 645’s remote not only allows you to “learn” in the commands from any compatible remote; it also allows you to learn a separate code into the

Selector Buttons

d. This unique capability allows

you to configure the remote so that whenever one of these buttons is pressed, the remote will not only select the codes for that device for itself, but it will transmit a separately programmed remote code. By programming the

display’s

input selection remote code for the specific device, you can, for example, press the VID 3/Cable

Input Selector Button d

and not only have the AVR switch to a cable set-top for audio selection and have the AVR remote use remote codes for the cable box, but you can send a code to the display that selects the input used for a direct connection between the set-top and your display.

Before learning codes, note that all buttons on the remote may have a command “learned” except for

Clear j, Program y, Light z and the Macro Buttons .

Learning Codes for an Input Selector

The AVR 645’s remote allows you to learn a specific code to be attached to one of the d so that whenever that button is pressed, you will not only be selecting that device as the AVR’s input and telling the remote to use the remote codes that been programmed to belong to that device, it also you to have that special code transmitted, as well. This allows you to have an input (or other command) sent to a display so that when video sources are directly connected to the display, you can automatically command it to switch to the same input selected for the AVR.

Changing Devices

In the factory default settings, the AVR remote is programmed so that the commands transmitted correspond to the device selected by pressing one of the

Input Selectors3. This is logical, as you

want the remote to control the device you have selected. However, in some circumstances you may have configured your system so that the devices connected to the AVR 645 do not correspond to the default device settings and the legends printed on the remote. For example, if your system has two VCRs you may connect the second VCR to the VID 2 input. There is no problem in doing that, but in normal operation the commands issued after selecting the VID 2 input are for a television, not a VCR.

The AVR remote allows you to correct that situation through the “Changing Devices” process. This enables you to assign the codes from one type of device to a different button. For example, in the steps below, we will explain how to program the VID 2 buttons to provide the commands to operate a VCR. Of course, you may program the remote to have any of the devices take on the code set of any other device, as your system requires. And, with the AVR remote’s “Rename” function, you can even change the way the name of the device appears on the remote’s LCD so that you see exactly which commands are being sent.

To program the buttons normally assigned to one device for the commands of another, pleasefollow these steps:

Macro Programming

Macros enable you to easily repeat frequently used combinations of multiple remote control commands with the touch of a single button. Once a macro is programmed, you may send up to 20 commands with one press of the Power On or Macro buttons. This will greatly simplify the process of turning on your system, changing devices or other common tasks.

Punch-Through Configuration

Punch-through is a capability of the remote that allows the Volume controls, Channel Up/Down buttons or Transport keys (Play, Stop, Record, Fast Forward and Reverse, and Skip Up/Down) to link to a different device. For example, if your TV, cable box or satellite receiver is connected through the AVR 645, you will most likely want to use the AVR 645’s volume control commands even when the remote has been set to issue all other commands for the video device. “Punch-through” enables you to easily program the remote to do this.

Volume Punch-Through

Follow these steps to enable the Volume Up/Down and Mute controls from one device to be used when the remote is otherwise programmed for a different device.

NOTE FOR VOLUME PUNCH-THROUGH: The remote’s default settings are for the AVR 645’s volume controls, to be used when any input or device is selected, with the exception of the VID 2/TV button. There is no need to program the remote for volume punch-through for the AVR 645’s controls with other sources, such as DVD. To have the AVR 645’s volume commands used when the TV device is selected, follow these steps:

Figure 61

4. The next display screen (Figure 62) is where you select the device that will receive the punchthrough commands. In our example, that is the VID 2/TV button, as that is where we want the AVR 645’s volume controls to be active. Press

Renaming

While the names given to the buttons and inputs on the remote represent recognizable categories of audio/video products, system operation may be easier if the displays shown in the remote’s LCD screen are customized to reflect the specific characteristics of a playback source’s brand name or the new function given to a specific button when one remote’s controls are programmed into the AVR remote. The AVR remote allows you to change the name of either a master device or any button on the remote using the following steps.

Renaming a Device

To rename a specific device/input source button, follow these steps. For this example, we will show you how to rename the Device/Input Selector normally shown as “TV” to “HDTV TUNER.”

return the blinking cursor to the far left side of the display line. You may then retitle the device name as shown in the next step.

6. To enter the new name, press the

Numeric Keys

. The letters above the numbered buttons indicate which letter or symbol will appear when the button is pressed during the renaming process. The first press of the button will enter the first letter shown, subsequent presses of the same button will change the display to the other letters above that numbered key. For example, since the first letter we need to rename the input to HDTV Tuner is an “H”, you would locate the “H” above the “4” button, and press the button twice. The first press shows a “G,” the second press changes it to an “H.” Consult the table at the end of this section to see which characters pressing a particular button generates.

7. After you enter the first letter of the new device name, there are three options for entering the next character:

a. To enter a letter that requires a different

numeric key to be pressed, simply press that button. The cursor will automatically move to the next position and the first letter accessed by the new button will appear. Following our example, the next letter needed is a “D,” so you would press the “3” button once.

b. To enter a letter that uses the same numeric

key, you must first press the

Button

D to move the blinking cursor block

to the next position. Then press the

• Renaming a device changes the name of the device only, not any of the individual key functions within that device memory. To change the name of an individual device, follow the instructions in the next section.

Renaming Individual Keys

Thanks to the programming flexibility of the AVR remote, an individual button on the remote may be assigned a feature or function that is different from the name that appears as the factory default when the button is pressed. However, with the Rename Key function it is possible to rename almost any button on the remote so that when the button is pressed you will see a more descriptive or appropriate name displayed.

To rename a specific button on the remote, follow these steps. For this example, we will show you how to rename the

Numeric Keys . The letters above the numbered buttons indicate which letters or symbols will appear when the button is pressed during the renaming process. The first press of the button will enter the first character shown, subsequent presses will change the display to the other letters above that numbered key. For example, since the first letter we need to rename the Tone button to Zoom is a “Z,” so you would locate the “Z” above the “9” button, and press the button four times. The first press shows a “W,” the subsequent presses step through the other letters available until the “Z” appears.

NOTES ON RENAMING KEYS:

• Renaming a key does not change its function. You may change the function of an individual key by learning a new code into the remote. See page 45 for more information.

• When a key is renamed it will only apply to the specific device selected in Step 4. The same key may be renamed as needed for each individual device with which it is used.

Resetting the Remote

Depending on the way in which the remote has been programmed, there may be a situation where you wish to totally erase all changes that have been made to the remote and return it to the factory defaults. You may do that by following the steps shown below, but remember that once the remote is reset, ALL changes that have been made, including programming for use with other devices, learned keys, macros, punchthrough settings and key names, will be erased and any settings you had previously made will have

to be reentered.

To erase all settings and reset the remote to the original factory default settings and displays, follow these steps:

The remote’s Device Priority mode allows you to select the length of time that the remote continues to issue codes for a device other than the AVR once you use the remote to control a source or other product. The default operation for the remote is to have all buttons on the remote return to their AVR functions 5 seconds after the last button press. However, you may program the AVR remote to remain active as the source device remote for 12 seconds, or to keep the source device’s codes active until another

Backlight Options

The AVR 645’s remote has a built-in backlight system that makes it easier to use the remote when the room lighting is dimmed for an optimal home theater experience. To turn the backlighting on, simply press the Light Button z. That button is made from a special “glow” material that makes it easier to find in dark rooms. This glow feature does not use any battery power, so the glow will fade when the remote is kept in a dark room for an extended period of time. You may “recharge” it by placing the remote in normal room lighting for a few hours.

Once the

Light Button z is pressed, the remote’s

backlighting will remain on for approximately 7 seconds, and when you press any button on the remote while the backlighting is on, the light will stay on for another 7 seconds. However, the remote’s “Couch” function will conserve battery power by turning both the backlighting and the LCD off when any button is pressed for more than 30 seconds.

You may also configure the remote so that the backlighting will come on, any time a button is pressed. To set this option, follow these steps:

CONFIGURING THE REMOTE

• Extensive use of the programming, learning and configuration functions of the remote may consume significantly more battery power than normal remote operation. While the batteries should last for four to six months in normal operation, you may find that they need to be changed sooner after the remote is programmed for the first time.

• When the batteries approach a level below which the remote will not function, the remote’s LCD screen will display a as shown in Figure 92. We strongly recommend replacing the batteries as soon as this message appears to avoid the loss of programming and configuration settings. These settings are when the batteries are changed quickly.

In addition to the items shown above, additional information on troubleshooting possible problems with your AVR 645, or installation-related issues, may be found in the list of “Frequently Asked Questions” which is located in the Product Support section of our Web site at www.harmankardon.com.

Processor Reset

In the rare case where the unit’s operation or the displays seem abnormal, the cause may involve the erratic operation of the system’s memory or microprocessor.

To correct this problem, first unplug the unit from the AC wall outlet and wait at least 3 minutes. After the pause, reconnect the AC power cord and check the unit’s operation. If the system still malfunctions, a system reset may clear the problem.

To clear the AVR 645’s entire system memory including tuner presets, output level settings, delay times and speaker configuration data, first put the unit in the

Standby Mode by pressing the

1. Next, press and hold the Surround Mode Group Selector

2 and the Tuning Mode Selector 8

buttons for 3 seconds.

The unit will turn on automatically and display the

RESET message in the Upper Display Line #.

NOTE: Resetting the processor will erase any configu-

ration settings you have made for speakers, output levels, surround modes, and digital input assignments, as well as the tuner presets. After a reset, the unit will be returned to the factory presets, and all settings for these items must be reentered.

Standby/On Switch

If the system is still operating incorrectly, there may have been an electronic discharge or severe AC line interference that has corrupted the memory or microprocessor.

If these steps do not solve the problem, consult an authorized Harman Kardon service center.

Newer discs with special DTS-ES discrete encoding will be decoded to provide six discrete, full-bandwidth

Dolby Pro Logic II Dolby Pro Logic II decodes full-range, discrete, left, center right, right surround and left surround channels from either matrix surround-encoded

Movie programs and conventional stereo sources when an analog input is in use. The Dolby Pro Logic II Movie mode is optimized for movie soundtracks, Music while the Pro Logic II Music mode should be used with musical selections. The Pro Logic II Game mode is designed to enhance the soundtrack Game of video games from either dedicated consoles or computers.The Pro Logic mode re-creates original Pro Logic processing for those who Pro Logic prefer that presentation.

Dolby Pro Logic IIx Dolby Pro Logic IIx is the latest extension of Dolby Laboratory’s benchmark matrix surround technology which creates a discrete 7.1 sound field from

Movie matrix surround or two-channel stereo sources when your system is configured for surround back speakers. Movie, Music and Game versions are Music available that customize the processing to the type of source in use. These modes may also be used to create 7.1 sound fields from 5.1 digital Game soundtracks.

Logic 7 Cinema Exclusive to Harman Kardon for A/V receivers, Logic 7 is an advanced mode that extracts the maximum surround information from either Logic 7 Music surround-encoded programs or conventional stereo material. When your system has been configured for use with Surround Back speakers

DTS Neo:6 Cinema These two modes are available when any analog source is playing to create a three-channel, five-channel or six-channel surround presentation from DTS Neo:6 Music conventional Matrix-encoded and traditional Stereo sources. Select the Cinema version of Neo:6 when a program with any type of analog Matrix

Hall 1, Hall 2 The two Hall modes create sound fields that resemble a small- (Hall 1) or medium-sized (Hall 2) concert hall.

Dolby Virtual Speaker Dolby Virtual Speaker technology uses a next-generation advanced algorithm to reproduce the dynamics and surround sound effects of a precisely Reference placed 5.1-channel speaker system using only front left and right speakers. In the Reference mode, the apparent width of the sound across the front Wide image is defined by the distance between the two speakers. The Wide mode provides a wider, more spacious front image when the two speakers are

5-Channel Stereo This mode takes advantage of multiple speakers to place a stereo signal at both the front and back of a room. Depending on whether the AVR 7-Channel Stereo has been configured for either 5.1 or 6.1/7.1 operation, one of these modes, but not both, is available at any time. Ideal for playing music in

(see page 41), you may choose between either 7.1 or 5.1 versions of the Logic 7 modes, while only the 5.1 versions are available when there are no Surround Back speakers. The Logic 7 C (or Cinema) mode should be used with any source that contains Dolby Surround or similar matrix encoding. Logic 7 C delivers increased center channel intelligibility, and more accurate placement of sounds with fades and pans. The Logic 7 M (or Music) mode enhances the listening experience by presenting a wider front soundstage and greater rear ambience. Both Logic 7 modes also direct low-frequency information to the subwoofer (if installed and configured) to deliver maximum bass impact. Logic 7 adds additional bass enhancement that circulates low frequencies in the 40Hz to 120Hz range to the front and surround speakers to deliver a less localized soundstage that seems broader and wider than when the subwoofer is the sole source of bass energy. Logic 7/7 may also be used to add surround back channels to many 5.1 digital soundtracks.
