AVR745

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

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

semiconductor "chip" components.

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

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

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

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

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

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

harman/kardon

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

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

sufficient to damage ES devices.

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

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

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

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

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

CAUTION :

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

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

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

Each precaution inthis manualshould be followed during servicing.

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

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

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

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

SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must not exceed o.5mA.

ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.

A Fan Vents: These ventilation holes are the output of the AVR 745’s airflow system. To ensure proper operation of the unit and to avoid possible damage to delicate surfaces, make certain that these holes are not blocked and that there is at least 3 inches of open space between the vent holes and any wooden or fabric surface. It is normal for the fan to remain off at most normal volume levels. An automatic temperature sensor turns the fan on only when it is needed.

B Full Carrier IR Output: The output of this jack is the full signal received at the

Window

^ or input through the IR Input F includ-

ing the carrier frequency that is removed from signals at the

IR Output C. Use this output to extend IR

remote signals to the input of compatible products by direct connection or through the use of optional, external IR “blasters”. If you are in doubt as to which of the two IR Output jacks to use, we recommend that you consult with your dealer or installer, or check with the manufacturer of the external equipment you wish to control.

C IR Output: This connection permits the IR sensor in the receiver to serve other remote controlled devices. Connect this jack to the “IR IN” jack on compatible Harman Kardon equipment.

D Center Channel Speaker Outputs: Connect these outputs to the matching + and – terminals on your center channel speaker. In conformance with the CEA color-code specification, the green terminal is the positive (+) terminal that should be connected to the red (+) terminal on speakers with the older color-coding. Connect the black (–) terminal on the AVR to the black negative (–) terminal on your speaker. (See page 15 for more information on speaker polarity.)

E Surround Back/Multiroom Speaker Outputs:

These speaker terminals are normally used to power the surround back left/surround back right speakers in a 7.1-channel system. However, they may also be used to power the speakers in a second zone, which will receive the output selected for a multiroom system. To change the output fed to these terminals from the default of the Surround Back speakers to the Multiroom Output, you must change a setting in the Advanced Menu of the OSD system. See page 51 for more information on configuring this speaker output.

In normal surround system use, the brown and black terminals are the surround back left channel positive (+) and negative (–) connections and the tan and black terminals are the surround back right positive (+) and negative (–) terminals. For multiroom use, connect the brown and black SBL terminals to the red and black connections on the left remote zone speaker and connect the tan and black SBR terminals to the red and black terminals on the right remote zone speaker.

Remote Sensor

F IR Input: If the AVR 745’s front-panel IR sensor is blocked due to cabinet doors or other obstructions, an external IR sensor may be used. Connect the output of the sensor to this jack.

G Switched AC Accessory Outlet: This outlet may be used to power any device you wish to have turned on when the AVR 745 is turned on with the

On Switch IMPORTANT NOTE: The power consumption of any

device connected to the accessory outlet should not exceed 100 watts. Never connect high-power devices such as amplifiers or video displays to the accessory outlet.

H Trigger 1 Output: Connect this jack to the “Trigger In” jack of an optional external component such as an audio power amplifier that you want to be controlled to mirror the power state of the AVR 745. When this connection is used, the AVR 745 will automatically send a low-voltage signal to the connected device that turns it on when the AVR 745 is on and off when the AVR 745 is placed in the Standby Mode. The connected component must respond to 6-volt presence as the control signal.

INSTALLATION AND CONNECTIONS

harman/kardon

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.

Before starting to connect your AVR 745 to the source devices, display device, speakers and other components in your system, you should also unpack the TC 30 remote, which is found in the separate box inside the AVR 745 carton. So that the TC 30 is ready when you begin the system configuration process, install the battery, connect the charger and place the remote in the charging cradle, as it takes approximately twelve hours for the battery to fully charge.

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 745.

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

ab on the rear panel of the AVR 745 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

l .

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.

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

with a gauge of 14 or smaller.

front-left and front-right or surround-left and surround-right speakers, even if the speakers are a different distance from the AVR 745.

8. Connections to a single subwoofer are normally made via a line-level audio connection from the Main Subwoofer 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. If your system uses two subwoofers, connect the

Subwoofer 2 Output 9 jack on the AVR to

the Line Input of the second subwoofer.

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 f.

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

Video Inputs

Record/In jacks from that device to the

Video Outputs

2. Connect analog Audio Left/Right Play/Out jacks of the device connected to the Video 1 Inputs to the Video 1 Audio Inputs g on the AVR. Connect the analog Audio Left/Right Record/In jacks from that device to the the AVR. If the device has a digital audio output, connect it to one of the digital audio inputs.

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 22 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.

• If you have a video display with an HDMI or DVI input, make the connection using the

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

• If your display does not have digital or component video inputs, connect the Output R 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 convert signals back and forth from digital to analog to deliver a higher quality signal when used with digital sources.The signals carried on HDMI may, but do not always, include audio, offering the possibility of a complete 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 of the HDMI Inputs N on the AVR. If the product is a DVD-Audio player or other source that has multichannel analog audio outputs, connect them to the 8-Channel Direct Inputs f. 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

Component Video

Video Monitor

between the source and the AVR 745 to either the

Coaxial dM or Optical eK 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 f.

• HDMI 1.2

as shown above for HDMI 1.1, except that a separate analog connection is not needed for SACD players.

• It is not possible to feed an analog composite or S-video signal to a recorder or the AVR’s multizone system when an HDMI input is in use. If an HDMIequipped source also has analog audio and video outputs, connect them to the Video VW and Audio hi on the AVR.

• 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 or remote zone 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 M to an HDMI input on your video display.Thanks to the AVR 745’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.

Multiroom Audio Connections

The AVR 745 is equipped with multizone capabilities that allow it to send a separate audio and video 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 745’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 745, plug the audio interconnect cables into the

Audio Outputs Option 2: Connect the Multiroom Audio Outputs

U on the AVR 745 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 745’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 745 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

Multiroom Video Connections

The AVR 745’s multiroom system is designed to send both video and audio signals to a remote room location. This may be the same source that is in use in the main room, or you may select a separate input source through the Multiroom menu or remote, as explained on page 52.

The only additional connection required to add video capabilities to your multiroom system is to connect the Multiroom Video Output L either directly to the video display in the remote room or to any optional video distribution amplifiers that may be required when the length of the connection cable is such that additional amplification is required.

The following items may be of additional assistance when using video as part of a multiroom system with the AVR 745.

•

Component or HDMI video sources may not be routed

through the multiroom system. When using a component video device, you should also make a composite connection for the multiroom system.

• As with all cable installations, when running any wiring inside a wall be certain that the cable carries the proper NEC rating for the application. The use of improperly rated cables may present a safety hazard. Consult a qualified installer or licensed electrician should you have any questions about the use of in-wall cables for video or audio.

• When connecting the AVR 745 to the remote room video display, be aware of the distance limitations that may exist for both composite and S-video connections. Although the use of low-loss coax for composite video and higher-grade S-video cables may reduce signal loss, optional distribution amplifiers may occasionally be required when long cable runs are used.

A-BUS®Installation Connections

The AVR 745 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 745 with an approved A-BUS product, simply connect it to the AVR 745 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 745 routes the signals to their proper destination for power, signal source and control. The output fed to the A-BUS jack is determined by the AVR 745’s multiroom system and menus.

RS-232 Connections The AVR 745 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 745’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 745 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. If you do not need the USB cable provided with the AVR 745 for programming the TC 30 remote, it may be used for this purpose.

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 rear panel.

NOTES ON USB:

• The USB jack on the AVR 745 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 745’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 Connections

The AVR 745 is equipped with two low-voltage triggers 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.

Surround Mode Selection

One of the most important features of the AVR 745 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 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-television 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 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 745 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 745 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 is also available in the standard Dolby Digital format so that it may be decoded by the AVR.

An optional, external RF demodulator is required to use the AVR 745 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 KMde of the AVR 745. 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 745 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 to the incoming digital audio data stream to identify the selected:

• 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 19), as shown on page 28.

• When a disc with the Dolby Digital EX format flag is played, your system will automatically switch to the EX mode when seven main-channel 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 sys-

Optical

DEFAULT

tem, or Dolby Digital with 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 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-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 745.All that is required is to connect the player’s output to either an on the rear panel de 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 745 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.

• 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 28.

Selecting a Digital Source

To utilize either digital mode, you must have properly connected a digital source to the AVR 745. Connect the digital outputs from DVD players, HDTV receivers, satellite systems or CD players to the

Optical or

Coaxial Inputs KMde. 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 745 rear panel (e.g., connect the analog stereo audio output from a DVD to the

DVD Audio Inputs

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 22, first select the input using the remote or front-panel controls, as outlined in this manual. Next, press the

Devices Button 4, followed by the

Screen Button 6 at the top of the row of buttons

on the left side of the TC 30, to the left of the A/V receiver image on the LCD screen. After the list of options displayed in the

LCD Screen 7 changes,

press the Screen Button 6 to the left of Setup Menu. After the options change, press the

Button

to the right of Digital Input

Screen

and then press the ‹/›Navigation Buttons D on the TC 30 remote or the H on the front panel to

CAL

or COAXIAL

‹/›

Navigation Button

choose any of the OPTI- inputs, as they appear in the

Upper Display Line # or on-screen display. When the digital source is playing, the AVR 745 will automatically detect which type of digital data stream is being decoded and display that information in the

Display Line

Upper

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 22

Digital Bitstream and Surround Mode Indications

When a digital source is playing, the AVR 745 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 745 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 745 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 indica-

tion (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 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 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

PCM signal is

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 Pro Logic II processing is applied, as shown on page 27.

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

USB Playback

The AVR 745 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 amplifier, 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.

OPERATION

harman/kardon

The AVR 745’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 jacks on your computer or a USB hub to the

USB Jack Z 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, or you may use the cable supplied for use with the TC 30 remote, if it is not being used to program the remote.

In addition, you will need to have a media player installed on the computer. The AVR 745 has been tested for operation with Windows Media Player Version 8.0 and above, but it is also compatible with many other popular players such as iTunes and Real Player®. 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 jack on a computer 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

Input Source Selector Button 6 until

USB appears as the input name in the

Transport

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 appro-

priate 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 745 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 31).

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 745. 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 745 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 745. 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 posi-

Figure 31

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.

tion 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.

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 745 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 745.

• 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 745 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

Tape Outputs a and Video 1 Audio Outputs

g. However, the digital signals will be passed

through to the

Digital Audio Outputs abM.

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 745 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 Y on the rear panel of the AVR 745. 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

Selector

6. If XM was the last used tuner source, it will appear; or press the button again until XM Radio is heard. Press the to change stations within a frequency band. Press the

Recording

In normal operation, the audio or video source selected for listening through the AVR 745 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/Video 2 Audio and Video Outputs ‡· in the record mode.

When a digital audio recorder is connected to the Digital Audio Outputs k M, 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 745 offers Harman Kardon’s exclusive configurable front-panel output-jack feature. For easy connection of portable devices, you may switch the frontpanel

Video 4 Jacks N or the Coaxial Digital 4

long as the AVR 745 is turned on, unless the setting is changed in the OSD menu system, as described above. However, once the AVR 745 is turned off, the setting is canceled. When the unit is turned on again, the front-panel jacks will return to their normal default setting as inputs. If you wish to use the jacks as outputs at a future time, the setting must be changed again using the OSD menu system, as described above.

Output Level Trim Adjustment

Normal output level adjustment for the AVR 745 is established using EzSet/EQII, as outlined on pages 29–33. In some cases, however, it may be desirable to trim the output levels using program material such as a test disc, or a selection you are familiar with. Additionally, the output level for the subwoofer can only be adjusted using this procedure.

To adjust the output levels using program material, first set the reference volume for the front left and front right channels using the Volume Control )

Press the Devices Button 4 on the TC 30 remote and then press the Receiver. Next, press the Screen Button 6 next to Setup Menu and after the choic- es in the

EzSet/EQII Operation

A major advantage of EzSet/EQII over competitive systems is its ability to store up to three different EQ Designs.This allows you to preset different combinations of speakers or manually set adjustments, or perhaps create different EQ Designs with the microphone in different locations to optimize the system for either your favorite listening position, or for a different setting when more people are in the listening room. You may also turn off the EzSet/EQII system entirely so that you may compare the sound of your system with the system in a particular EQ Design, or with it out of the system.

To access the settings for selecting an EQ Design preset, press the followed by the the row of buttons on the left side of the TC 30, to the left of the list of options displayed in the changes, press the Page Left/Right Button 8 to go to the second page of AV Receiver settings.When that page of settings appears, you may do the following:

• Press the

On/Off

path, or to put the system in the Bypass mode, which removes the equalization filters.

• Press the

Presets

stored in each of the three memory positions, as shown in the instructions on page 38.

Subwoofer Control

If you have a 7.2 system with two subwoofers present, you may occasionally wish to turn one of the subwoofers off to accommodate your preferences with a particular movie or musical program, or to demonstrate the change made by using one subwoofer or two.To do this, press the the TC 30 followed by the the top of the row of buttons on the left side of the TC 30, to the left of LCD screen. After the list of options displayed on the LCD Screen 7 changes, press the LCD Screen 7 to go to the second page of AV Receiver settings.When that page of settings appears, press the

Dim Function

Since the AVR 745 will often be used when movies or other kinds of video programming are viewed under low-light conditions, you may wish to lower the brightness of the front-panel displays and indicators so that they do not distract from the video presentation. You

may dim the displays using the menu system, as shown on page 49, or you may control the brightness directly from the remote.

Press the and then press the

Receiver

and after the choices in the LCD Screen 7 change, press the Screen Button 6 next to Dim. Note that when the displays are dimmed or turned off, the blue lighting around the

Switch

the AVR is still turned on.The accent lighting for the Volume Control ) will remain at its normal level, rather than dim when the panel displays are at halfbrightness.

Note that all changes to the front-panel brightness level are temporary; the displays will return to fullbrightness after the AVR is turned off and then on again. To return the displays to full-brightness without turning the unit off, return the TC 30 to the AVR Device screen, and press the next to Dim as needed until the displays are on.

In addition to lowering the brightness of the displays or turning them off completely, you may wish to have them appear whenever a button on the remote or front panel is pushed, and then gradually fade out after a set time period. You may do this by making the appropriate settings in the

OUT

menu, as shown on page 49.

Memory Backup
