Introduction

Congratulations! With the purchase of the Harman Kardon AVR45 you are about to begin many years of listening enjoyment. The AVR45 has been custom designed to provide all the excitement and detail of movie sound tracks and every subtle nuance of musical selections. With on-board Dolby * Digital Decoding, the AVR45 delivers six discrete channels of audio that take advantage of the digital sound tracks from the latest DVD and LV releases, as well as future HDTV broadcasts. While complex digital systems are hard at work within the AVR45 to make all of this happen, hookup and operation are simple. Color-keyed connections and a comprehensive programmable remote control make the AVR45 easy to use. To obtain maximum enjoyment from your new receiver, we urge you to take a few minutes to read through this manual. This will ensure that connections to speakers, source playback units and other external devices are made properly. In addition, a few minutes spent learning the functions of the various controls will enable you to take advantage of all the power the AVR45 is able to deliver.

If you have any questions about this product, its installation or operation, please contact your dealer. They are your best local source of information. Description and Features The AVR45 is a full-featured A/V receiver, incorporating a wide variety of listening options. In addition to Dolby Digital decoding, Dolby Pro Logic * and Dolby 3 Stereo are available for compatibility with the tens of thousands of movies and television programs encoded with analog surround information. A choice of Hall and Theater modes is also available for use with both encoded sources and traditional two-channel stereo recordings. A total of four audio/video inputs, as well as two additional audio-only inputs, and an FM stereo/FM/AM tuner are available for the utmost flexibility. Frontpanel A/V inputs simplify connections to video games or camcorders. The AVR45's powerful amplifiers use traditional Harman Kardon High-Current Design philosophies to meet the wide dynamic range of any program selection.

Harman Kardon invented the highfidelity receiver more than forty-five years ago. With state-of-the-art features and time-honored circuit designs, the AVR45 is one of the finest receivers ever offered by Harman Kardon.

Installation and Connections
14

System Installation After unpacking the unit, and placing it on a solid surface capable of supporting its weight, you will need to make the connections to your audio and video equipment. These steps need to be done only when the receiver is first installed, or when a change is made to the input source equipment. Audio Equipment Connections We recommend that you use high-quality interconnect cables when making connections to source equipment and recorders to preserve the quality of the signals. When making connections to audio source equipment or speakers it is always a good practice to unplug the unit from the AC wall outlet. This prevents any possibility of accidentally sending audio or transient signals to the speakers that may damage them. 1. Connect the analog output of a CD player to the CD inputs §. NOTE: When the CD player has both fixed and variable audio outputs it is best to use the fixed output unless you find that the input to the receiver is so low that the sound is noisy, or high that the signal is distorted. 2. Connect the Play/Out jacks of a cassette deck, MD or other audio recorder to the Tape Monitor In jacks c. Connect the Record/In jacks on the recorder to the Tape Monitor Out jacks d on the AVR45.

3. Connect the output of any digital sources to be used to the appropriate connections on the AVR45 rear panel. Note that the Optical and Coaxial digital inputs · ° may be used with either a Dolby Digital (AC-3) source or the output of a conventional CD or LV player's PCM (SP/DIF) output. 4. Assemble the AM Loop Antenna supplied with the unit as shown below. Connect it to the AM and GND screw terminals ¡.

Your dealer or installer is a valuable resource to consult in selecting the proper cable. Regardless of the brand of cable selected, we recommend that you use a cable constructed of fine, multistrand copper with a gauge of 14 or smaller. Remember that in 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 ten 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 electrical contractor who is familiar with the NEC and/or the applicable local building codes in your area. When connecting wires to the speakers, be certain to observe proper polarity. Remember to connect the "negative" or "black" wire to the same terminal on the receiver and the speaker. Similarly, the "positive" or "red" wire should be connected to the like terminal on the AVR45 and speaker. 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 AVR45.

5. Connect an FM antenna to the
FM (75 ohm) connection TM. The

FM antenna may be an external roof antenna, an inside powered or wire lead antenna or a connection from a cable TV system. Note that if the antenna or connection uses 300-ohm twin-lead cable, you must use the 300-ohm-to75-ohm adapter supplied with the unit to make the connection. 6. Connect the front, center and surround speaker outputs , / l to the respective speakers. To assure 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 this receiver, the type of speakers you use, personal preferences and other factors.

Installation and Connections
15

NOTE: While most speaker manufacturers adhere to an industry convention of using black terminals for negative and red ones for positive, some manufacturers may vary from this configuration. To assure proper phase, and optimal performance, consult the identification plate on your speaker, or the speaker's manual to verify polarity. If you do not know the polarity of your speaker, ask your dealer for advice before proceeding, or consult the speaker's manufacturer. 7. Connections to a subwoofer are made via a line level audio connection from the Subwoofer Output ª to the line level input of a subwoofer with a built-in amplifier. If a passive subwoofer is used, the connection first goes to a power amplifier, which will be connected to one or more subwoofer speakers. Video Equipment Connections Video equipment is connected in a fashion similar to audio components. Again, the use of high-quality interconnect cables is recommended to preserve signal quality. 1. Connect a VCR's audio and video Play/Out jacks to the Video 1 In jacks £ on the rear panel. The audio and Record/In jacks on the VCR should be connected to the Video 1 Out jacks ¢ on the AVR45. 2. Connect the audio and video outputs of a satellite receiver, cable TV converter or television set or any other video source to the Video 2 In jacks fl. 3. Connect the audio and video outputs of a DVD or laser disc player to the DVD jacks ¶. 4. Connect the TV Monitor Out jacks on the receiver to the video input of your television monitor or video projector.

System and Power Connections
The AVR45 is designed for flexible use with external control components and power amplifiers. These connections are easy to make during an initial installation, or at a later date should you choose to upgrade your system. Remote Control Extension If the receiver is placed behind a solid or smoked glass cabinet door, the obstruction may prevent the remote sensor from receiving commands. In this event, an optional remote sensor may be used. Connect the output of the remote sensor to the Remote Cont. In jack a. If other components are also prevented from receiving remote commands, only one sensor is needed. They may use this unit's sensor or a remote eye by running a connection from the Remote Cont. Out jack b to the Remote In jack on Harman Kardon or other compatible equipment. External Audio Power Amplifier Connections If desired, optional external power audio power amplifiers may be used with the AVR45. Connections to these amplifiers are made by using audio interconnect cables connected to both the Preamp Outputs · on the rear panel and the audio input jacks of the external amplifiers. External Audio Decoder Connection To provide for the ultimate flexibility, the AVR45 may be used in conjunction with optional, external decoders for digital audio systems other than the AVR45's own built-in Dolby Digital system. If an external decoder is used, connect the output jacks of the decoder to the 6-Channel Direct inputs , making sure to match channels.

These jacks may also be used for connections to devices usch as DVD players or High Definition Television (HDTV) sets or decoders that feature built-in digital surround decoders. Although the digital decoding system in the AVR45 will typically provide audio performance that is superior to other decoders, you may use these jacks to provide an additional 6-channel input for connection to a DVD player or HDTV set with a built-in decoder and discrete 6-channel analog outputs. AC Power Connections This unit is equipped with two accessory AC outlets. They may be used to power accessory devices, but they should not be used with high-current draw equipment such as power amplifiers. The total power draw may not exceed 50W to each outlet. The Switched > outlet will receive power only when the unit is on. This is recommended for devices that have no power switch, or a mechanical power switch that may be left in the "ON" position. NOTE: Devices with electronic power switches may only go into a Standby mode when plugged in here. The Unswitched < outlet will receive power as long as the unit is plugged into a powered AC outlet. Finally, when all connections are complete, plug the power cord into a nonswitched 120-volt AC wall outlet. You're almost ready to enjoy the AVR45!

System Configuration
16

When all audio, video and system connections have been made, there are a few configuration adjustments to be made. A few minutes spent to correctly configure and calibrate the unit will greatly add to your listening experience. Speaker Selection and Placement The placement of speakers in a multichannel-home-theater system can have a noticeable impact on the quality of sound reproduced. No matter which type or brand of speakers is used, the same model or brand of speaker should be used for the front left, center and right speakers. This creates a seamless front soundstage, and eliminates the possibility of distracting sonic disturbances that occur when a sound moves across mismatched front channel speakers. Speaker Placement Depending on the type of center channel speaker in use and your viewing device, place the center speaker directly above or below your TV or in the center behind a perforated front projection screen. Once the center channel speaker is installed, position the left and right front speakers so that they are as far away from one another as the center channel speaker is from the preferred listening position. Ideally, the front channel speakers should be placed so that their tweeters are no more than 24" off center from the tweeter in the center channel speaker. Depending on the specifics of your room acoustics and the type of speakers in use, you may find that imaging is improved by moving the front left and right speakers slightly forward of the center channel

speaker. If possible, adjust all front loudspeakers so that they are aimed at ear height when you are seated in the listening position. Using these guidelines, you'll find that it takes some experimentation to find the correct location for the front speakers in your particular installation. Don't be afraid to move things around until the system sounds correct. Optimize your speakers so that pans across the front of the room sound smooth, and that sounds from all speakers appear to arrive at the listening position at the same time without delay from the center speaker as opposed to the left and right speakers. Surround speakers should be placed on the side walls of the room, at or slightly behind the listening position. The center of the speaker should face into the room. The speakers should be located so that the bottom of the cabinet is at least two feet higher than the listeners' ears when seated in the desired area. If side wall mounting is not practical, the speakers may be placed on a rear wall, behind the listening position. Again, they should be located so that the bottom of the cabinet is at least two feet higher than the listeners' ears. The speakers should be no more than six feet behind the rear of the seating area. Subwoofers produce non-directional sound, so they may be placed almost anywhere in a room. Subwoofer placement is highly influenced by room size and shape, and the type of subwoofer used. Follow the instructions of the subwoofer's manufacturer, or experiment with the best location for a subwoofer in your listening room.

System Setup Once the speakers have been placed in the room and connected, the final step in the setup process is to enter the settings that configure the AVR45's bass management system for the type of speakers used in your system, the calibration of the output levels and the delay times used by the surround sound processor. Before proceeding further, this is a good time to review the installation section of the manual to make certain that all connections are properly made. You are now ready to power up the AVR45 to begin these final adjustments. 1. Plug the Power Cable fi to an unswitched AC outlet. 2. Press the Main Power Switch 1 in so that it latches in with the "OFF" wording on the top of the switch inside the front panel. Note that the Power Indicator 3 will turn amber, indicating that the unit is in the Standby mode. 3. Install the four supplied AAA batteries in the remote as shown. Be certain to observe the (+) and (­) polarity indicators shown in the bottom of the battery compartment.

4. Turn the AVR45 on either by pressing the System Power Control 3 on the front panel, or via the remote by first pressing the AVR Selector a, and then pressing the Power button c . The Power Indicator 3 will turn green to confirm that the unit is on, and the Information Display will also light up. Speaker Configuration The first few adjustments tell the AVR45, which type of speakers are in use. This is important as it adjusts the settings that determine which speakers receive lowfrequency (bass) information. For each of these settings use the LARGE setting if the speakers for a particular position are traditional full-range loudspeakers that are capable of reproducing sounds below 100Hz. Use the SMALL setting for smaller, frequency-limited satellite speakers that do not reproduce sounds below 100Hz. Note that when "small" speakers are used, a subwoofer is required to reproduce low-frequency sounds. Remember that the "large" and "small" descriptions do not refer to the actual physical size of the speakers, but their ability to reproduce low-frequency sounds. If you are in doubt as to which category describes your speakers, consult the specifications in the speakers' owner's manual, or ask your dealer.

With the AVR45 turned on, follow these steps to configure the speakers: 1. Put the AVR45 in the Dolby Pro Logic mode by pressing the Dolby Pro Logic Selector Ó on the front panel or by pressing the Surround Mode Selector y on the remote, followed by the / / ¤ buttons g until PRO LOGIC appears in the Main Information Display S and the PRO LOGIC indicator F lights. 2. Press the Speaker button x on the remote or front panel. The words FRNT SPEAKER will appear in the Main Information Display S . 3. Press the Set button i ~. 4. Press the / / ¤ buttons g on the remote or the Selector buttons ¸ on the front panel until either LARGE or SMALL appears to match the type of speakers you have at the left front and right front positions, as described by the definitions shown below. When SMALL is selected, lowfrequency sounds will be sent to the subwoofer output only. Note that if you choose this option, and there is no subwoofer connected, you will not hear any low-frequency sounds from the front channels.

System Configuration
18

When LARGE is selected, a fullrange output will be sent to the front left and right outputs, and NO low-frequency signals will be sent to the subwoofer output. 5. When you have completed your selection for the front channel, press the Set button i ~, and then press the / / ¤ buttons g on the remote or the Selector buttons ¸ on the front panel to change the display to CEN SPEAKER. 6. Press the Set button i ~ again, and use the / / ¤ buttons g on the remote, or the Selector buttons ¸ on the front panel, to select the option that best describes your system based on the speaker definitions shown above. When CEN SP SMALL is selected, low-frequency center channel sounds will be sent to the subwoofer output only. Note that if you choose this option and there is no subwoofer connected, you will not hear any low-frequency sounds from the center channel speaker. When CEN SP LARGE is selected, a full-range output will be sent to the center speaker output, and NO center channel signal will be sent to the subwoofer output.

When CEN SP NONE is selected, no signals will be sent to the center channel output. The receiver will operate in a "phantom" center channel mode and center channel information will be sent to the left and right front channel outputs. 7. When you have completed your selection for the center channel, press the Set button i ~, and then press the / / ¤ buttons g on the remote or the Selector buttons ¸ on the front panel to change the display to SUR SPEAKER. 8. Press the Set button i ~ again, and then use the / / ¤ buttons g on the remote or the Selector buttons ¸ on the front panel to select the option that best describes your system based on the speaker definitions shown above. When SUR SP SMALL is selected, low-frequency surround channel sounds will be sent to the subwoofer output only. Note that if you choose this option and there is no subwoofer connected, you will not hear any low-frequency sounds from the surround speaker. When SUR SP LARGE is selected, a full-range output will be sent to the surround channel outputs, and NO surround channel signals will be sent to the subwoofer output.

When SUR SP NONE is selected, surround sound information will be split between the front left and front right outputs. Note that for optimal performance when no surround speakers are in use, the Dolby 3 Stereo mode should be used instead of Dolby Pro Logic. 9. When you have completed your selection for the surround channel, press the Set button i ~, and then press the / / ¤ buttons g on the remote or the Selector buttons ¸ on the front panel to change the display to S W SPEAKER. 10. Press the Set button i ~, and then press the / / ¤ buttons g on the remote or the Selector buttons ¸ on the front panel to select the option that best describes your system. Select S-W SP ON if a subwoofer is connected to your system. Select S-W SP OFF if a subwoofer is NOT connected to your system. Note that when no subwoofer is selected, low-frequency sounds below 100Hz will be sent to the front left/right speakers, provided that the selection in step 4, above, has been set to LARGE. Otherwise, no low-frequency sounds will be heard. This option is not available when the front, center or surround speakers are set to SMALL.

11. When all speaker selections have been made, press the Set button i ~ to return to normal operation. Output Level Adjustment Output level adjustment is a key part of the configuration process for any surround sound product. It is particularly important for a Dolby Digital receiver such as the AVR45, as correct outputs will ensure that you hear sound tracks in their proper place with the proper intensity. IMPORTANT NOTE: Many 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 ambiance, an 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 rear/ 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. Before beginning the 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. Finally, make certain that the Balance Control 7 is set to the center "12 o'clock" position.

To adjust and calibrate the output levels, follow these steps. For accurate calibration, it is a good idea to make these adjustments from the location in your room that is your favorite listening position: 1. Put the AVR45 in the Dolby Pro Logic mode by pressing the Dolby Pro Logic Selector Ó on the front panel or by pressing the Surround Mode Selector y on the remote, followed by the / / ¤ buttons g until PRO LOGIC appears in the Main Information Display S and the PRO LOGIC indicator F lights. 2. Press the Test Tone button e Ò on the remote or front panel. The words T -T FL 0dB will appear in the Main Information Display S , and the letters FL will flash once each second. 3. At this point, the test noise will begin to circulate among all the speakers in a clockwise rotation. NOTE: This is a good time to verify that the speakers have been properly connected. As the test noise circulates, listen to make certain that the sound comes from the speaker position shown in the Main Information Display. If the sound from a speaker location does NOT match the position indicated in the display, turn the AVR45 off and check the speaker wiring to make certain that each speaker is connected to the correct output terminal.

4. After checking for speaker placement, let the test noise circulate again, and listen to see which channels sound louder than the others. Using the front left (FL in the display) speaker as a reference, press the / / ¤ buttons g on the remote or the Selector buttons ¸ on the front panel on each channel to begin to bring them to the same level. Note that when one of the buttons is pushed, the test noise circulation will pause on the channel being adjusted to give you time to make the adjustment. When you release the button, the circulation will resume. 5. Continue to adjust the individual speakers until they all have the same volume. Note that adjustments should be made with the / / ¤ buttons g on the remote or the Selector buttons ¸ on the front panel only, NOT the main volume controls. Then press the Set button i ~ to memorize the change. If you are using a sound pressure (SPL) meter for precise level adjustment, set the volume so that the meter reads 75dB, C-Weighting Slow. NOTE: The subwoofer output level is not adjustable using the test tone. To change the subwoofer level, follow the steps for Output Level Trim Adjustment on page 27. 6. When you have adjusted the outputs so that all channels have the same level, press the Test Tone button e Ò on the remote or front panel to complete the adjustment.

Delay Settings One aspect of the surround modes is the delay of audio signals between the front speakers and the rear speakers. Each surround mode is factory preset with a specific delay time, but it is possible to individually adjust the delay timing to custom tailor the sound to your individual taste and the acoustic conditions in your listening room or home theater. The factory setting is appropriate for most rooms, but some installations create an uncommon distance between the front and surround speakers that may cause the arrival of front channel sounds to become disconnected from surround channel sounds. To resynchronize the front and surround channels, follow these steps: 1. Measure the distance from the listening/viewing position to the front speakers. 2. Measure the distance from the listening/viewing position to the surround speakers. 3. Subtract the distance to the surround speakers from the distance to the front speakers.

a. When setting the delay time for the Dolby Digital surround mode, the optimal delay time is the resulting figure. For example, if the front speakers are ten feet away and the surround speakers are five feet away, the optimal delay time is figured as 10­5=5. Thus, in this example, the delay should be set at five milliseconds. b. When setting the delay time for the Pro Logic mode, take the result of the subtraction and add 15 to obtain the optimal delay time. For example, if the front speakers are ten feet away and the surround speakers are five feet away, the optimal delay time is figured as 10­5+15=20. Thus, in this example, the delay should be set at twenty milliseconds. The Dolby Digital mode also provides a separate setting for the center channel delay mode, since the discrete nature of Dolby Digital signals makes the location of the center channel speaker more critical. To calculate the delay for the center channel, measure the distance from the preferred listening position in the center of the room to both th
