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.
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.
that the illumination around the Standby/On Switch 1 will turn amber, indicating that the 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.)

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

The IN VIDEO FORMAT line is an informational display of the resolution of the incoming video stream, and may not be adjusted. The IN VIDEO COPY PROT line is an informational display that shows whether or not an incoming video signal contains copy protection encoding, and may not be adjusted. The VIDEO PROCESS line is an informational display of the setting made in the IN/OUT SETUP menu indicating how incoming video is processed for the input being viewed, and may not be adjusted. The COMPONENT OUT line is an informational display of whether or not the Composite Video outputs are ENABLED or OFF, based on the input signal type and resolution, and whether or not the incoming video signal has HDCP content protection. It may not be adjusted. The S-VIDEO OUT line is an informational display of whether or not the S-video outputs are available at a 480i resolution (or OFF), based on the input signal type and resolution and whether or not the incoming video signal has HDCP content protection. It may not be adjusted. The DISPLAY INTER line allows you to choose between an ANALOG video output default value and an HDMI/DVI output by pressing the / Navigation Buttons D to make the desired selection. When the setting is ANALOG, the HDMI output is placed in a Standby mode so that it automatically switches to HDMI when an HDMI signal is detected. If a high-definition input source is not HDCP-content-protected, it may be output through the component jacks; otherwise, it will be sent only to the HDMI outputs. The HDMI/DVI setting routes all converted or processed video to the HDMI outputs. The HDMI AUDIO OUT line allows you to choose whether a two-channel downmix of the audio that accompanies the selected source is sent over the HDMI connection (YES) at the maximum bit rate the displays audio system is capable of handling, or not (NO). To change the setting, press the / Navigation Buttons D to make the desired selection.

TONE BASS TREBLE

Figure 5
The first line controls whether or not the bass/treble tone controls are in the signal path. The normal default is for them to be in-line, but if you wish to remove them from the circuit for flat response, first make certain that the cursor is pointing to the TONE line on the menu and press the / Navigation Buttons D so that OUT is highlighted. If you wish to leave the tone controls in the signal path, the amount off boost or cut for bass and treble may be adjusted up to 12dB in 2dB steps by pressing the / Navigation Buttons D so that the cursor is next to BASS or TREBLE, depending on which setting you wish to adjust. Next, press the / Navigation Buttons D until the desired setting is shown. When all desired changes have been made on this menu, press the / Navigation Buttons D so that the cursor is next to the BACK TO MASTER MENU line; press the Set Button p.

Video Monitor Settings

The VIDEO MONITOR SETTINGS menu (Figure 4) is unique in that it contains a mix of information display lines that detail status information about the AVR 645s video system settings, along with a few lines where a specific parameter may be changed. With the MASTER MENU on the screen, press the / Navigation Buttons D until the on-screen cursor is pointing to VIDEO MONITOR SETTINGS and then press the Set Button p to move to the menu screen.

Surround Setup

The next step is to set the surround mode you wish to use with the input that was previously selected in the IN/OUT SETUP menu. Since surround modes are a matter of personal taste, feel free to select any mode you wish you may change it later. However, to make it easier to establish the initial

Page 26

parameters for the AVR 645, we suggest Logic 7 (Cinema or Music) for most analog inputs. For inputs such as a CD Player, Tape Deck or Tuner, you may wish to set the mode to Stereo (Surround Off), as they are not typically used with multichannel program material, and it is unlikely that surround-encoded material will be used. Alternatively, the Logic 7 Music mode is a good choice for stereo-only source material. See page 60 for information on surround modes. For digital program material, the AVR will always examine the data stream and automatically select a Dolby Digital or DTS mode, as applicable. To begin the surround setup process, from the MASTER MENU (Figure 1), press the / Navigation Buttons D until the cursor is next to the SURROUND SETUP line. Press the Set Button p until the SURROUND SETUP menu (Figure 6) is on the screen.
** SURROUND SETUP ** SOURCE: VIDEO 1 AUDIO IN PORT: ANALOG AUDIO IN: PCM 44.1kHz ADC SAMPLING: 48K 96K SURR MODE: LOGIC 7 SELECT: MUSIC 5.1 DEFAULT SURR: ORIGINAL SURROUND CONFIG DOLBY SURR SETUP BACK TO MASTER MENU
When the desired setting has been made, or if no adjustment is required at this line, press the / Navigation Buttons D to move to the next configuration line. The SURR MODE and SELECT lines are related, as they guide you to the choice of the surround mode that will be activated whenever the input being configured is selected. At the SURR MODE line, press the / Navigation Buttons D to select the surround mode group (such as Dolby modes, DTS modes, Logic 7 modes, and DSP or Stereo modes) that is applicable to the input source. After making a selection, press the / Navigation Buttons D to move to the SELECT line. At the SELECT line, you are able to choose the specific mode to be used from within the major surround mode group. The choice of modes is governed by the input type (as some modes such as Dolby Digital or DTS-ES are not available for analog sources), as well as by the speaker configuration, since some modes are only available when a full 7.1 speaker complement is present. The full list of available modes is detailed in the surround mode chart on page 60. Also, you may also use the settings in the SURROUND CONFIG menus to delete modes you do not normally use from the available choices. When both a surround mode group and a specific surround mode have been selected, press the / Navigation Buttons D to move to the next configuration line. The DEFAULT SURR mode line is where you choose the mode that is activated when a digital source is selected. LAST will activate the last-used mode for any digital source. If you prefer to always have a digital source switch to the specific mode encoded by digital data flags in the incoming audio data stream, press the / Navigation Buttons D so that ORIGINAL appears. Before proceeding to the SURROUND CONFIG line, it is worth noting that the settings in the submenus attached to that line may require a considerable amount of time to complete. Although they are useful in that they allow you to customize the list of surround modes that appear in normal use of the AVR, you may wish to bypass those settings at this time so that you may complete the configuration process. You may return to this menu line at a later time, once you have had a chance to listen to the various surround modes and determine which you want to keep and which you do not want to use. The settings in this line are not primary controls and do not impact the way the AVR sounds. To proceed to the SURROUND CONFIG line, press the / Navigation Buttons D to

The DOLBY 2.0 CONFIG group contains the surround modes available when a two-channel Dolby Digital-encoded source is present. This includes both the discrete Dolby Digital modes, which cannot be turned off, as well as other modes which may be applied as post-processing on the source and system speaker configuration. The DTS CONFIG group contains the surround modes available when a DTS-encoded digital source is present. This includes both the discrete DTS Digital mode, which cannot be turned off, as well as other modes which may be applied as postprocessing on the source and system speaker configuration. The PCM 44.1/48kHz CONFIG group contains the surround modes available when a PCM digital data stream is present. This includes not only PCM sources from DVD or CD players, but also all two-channel analog sources that are in use, as they are converted to PCM within the AVR 645. The modes available include the proprietary Dolby modes (including Dolby Headphone and Dolby Virtual Speaker), DTS processing, our own Logic 7 modes, the conventional DSP modes (such as Hall and Theater) and the Stereo modes. The PCM 96kHz CONFIG group contains the surround modes available when a PCM digital data stream is present. This includes not only 96kHz PCM sources from DVD or CD players, but also all two-channel analog sources when 96kHz is chosen in the ADC SAMPLING mode line in the SURROUND SETUP menu. Available modes include proprietary Dolby modes (including Dolby Headphone and Dolby Virtual Speaker), DTS processing, our own Logic 7 modes, the conventional DSP modes (such as Hall and Theater) and the Stereo modes. When all surround modes that are not required have been turned off, press the / Navigation Buttons D until the on-screen cursor is pointing to BACK TO SURROUND CONFIG; then press the Set Button p. The final item on the SURROUND SETUP menu is the DOLBY SURR SETUP line. When the on-screen cursor is at this line, press the Set Button p to call the DOLBY SURROUND menu (Figure 8) up on the screen.

from disturbing others, without reducing the sonic impact of a digital source. To adjust the Night mode setting, make certain that the cursor is on the NIGHT line of the DOLBY menu. Next, press / Navigation Buttons D to choose between the following settings, as they appear in the on-screen display: OFF: When OFF is shown, the Night mode will not function. MID: When MID is shown, a mild compression will be applied. MAX: When MAX is shown, a more severe compression algorithm will be applied. We recommend that you select the MID setting as a starting point and change to the MAX setting later, if desired. When all settings on the DOLBY SURROUND menu have been competed, press the / Navigation Buttons D until the cursor is next to BACK TO SURROUND SETUP and press the Set Button p. You may then make any additional changes to the available options from that screen, or use / Navigation Buttons D to move the cursor to the BACK TO SURROUND CONFIG menu and press the Set Button p on the ZR 10 remote again to back up one menu. At the main SURROUND SETUP menu, you may change the SOURCE to make adjustments to another input, or when all input sources have been configured, use / Navigation Buttons D to move the cursor to the BACK TO MASTER MENU and press the Set Button p to return to the main menu so that you may move to the next step in configuring your AVR 645.

or manually configured as being available, additional options are available to further customize bass redirection. To change these settings, first make sure that the SPEAKER SIZE menu (Figure 19) is on the screen, and then press the / Navigation Button n so that the cursor is pointing to SUB MODE. Press the / Navigation Button n to begin the selection process, and note that the warning message (Figure 20) will appear reminding you to rerun EzSet/EQ after all changes have been made. The following options are available: The default setting for Large front left/right speakers when a subwoofer is present is SUB L/R + LFE. In this mode, all sounds below the crossover point set on the LFE LP FLT line will be sent to BOTH the subwoofer and the front left/right speakers. To send only the LFE channel information to the subwoofer, but have all other (derived) lowfrequency sounds sent to the front left/right speakers, select the SUB (LFE)setting. To have low-frequency information sent to the subwoofer only when Large speakers are selected, choose SUB (L/R).This option is only available when the unit is set to SURROUND OFF so that a pure analog audio path is provided. When no subwoofer is present and Large speakers are configured for the front left/right position, select NONE. This will route all low-frequency information to the front left/right speakers. When the SPEAKER SIZE menu returns to the screen, replacing the warning message, press the / Navigation Button n to make your selection. When the desired setting appears, press the / Navigation Button n to move the cursor to any other line on this menu where you wish to make a setting change, or go to the BACK TO MANUAL SETUP menu and then press the Set Button p to continue with overall configuration. Subwoofer Size The final setting on the SPEAKER SIZE menu enables you to change the setting for the subwoofer size. In the event that EzSet/EQ did not accurately enter the correct size, or if you wish to experiment with a different setting, first make sure that the SPEAKER SIZE menu (Figure 19) is on the screen; then press the / Navigation Button n so that the cursor is pointing to SUB SIZE and then press the / Navigation Button n to begin the selection process. Note that a warning message (Figure 20) will appear for 4 seconds to remind you to rerun EzSet/EQ after all changes have been made. Select a setting that best matches the diameter of your subwoofers driver, or which provides the appropriate high-pass filter setting for your system. In each case, the frequency of the high-pass filter determines the frequencies below which no information is sent to the subwoofer: The setting for an 8-inch/200mm driver activates a 38Hz subwoofer high-pass filter. The setting for a 10-inch/250mm driver activates a 30Hz subwoofer high-pass filter. The setting for a 12-inch/305mm driver activates a 20Hz subwoofer high-pass filter. The setting for a 15-inch/380mm driver activates a 15Hz subwoofer high-pass filter. When all changes to speaker-related settings have been made, press the / Navigation Button n until the cursor is on the BACK TO MANUAL SETUP menu; then press the Set Button p so that you may make any other adjustments to the system parameters. Remember to rerun the EzSet/EQ system if any changes have been made to the settings on this menu, following the instructions for using the Manual mode shown on page 28. 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. To make any changes to the delay settings, go to the DELAY ADJUST submenu within the MANUAL SETUP menu (Figure 18). To do this, first press the OSD Button U so that the MASTER MENU (Figure 1) appears. Next, press the / Navigation Button n until the cursor is on the EZSET/EQ line on the menu in use and press the Set Button p. Navigate to EZSET/EQ MANUAL SETUP and press the Set Button p. When the MANUAL SETUP menu is shown, press the / Navigation Button n again until the cursor is on the DELAY ADJUST line and press the Set Button p to view the DELAY ADJUST menu (Figure 21).

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 DVDs

Bridge

The AVR 645 is equipped for use with Harman Kardons optional TheBridge iPod docking station. When The Bridge is connected to the AVR and an iPod properly docked, you may use either remote to control the iPod for audio playback while using the front-panel display and on-screen semi-OSD messages to help you locate tracks or view information about the track being played. In addition, connecting an iPod to the AVR 645 through The Bridge also charges the iPods battery. Using the DMP AUTO POWER menu option, as described on page 45, you may even have the AVR 645 automatically turn on with your iPod as a playback source whenever the iPod is turned on.

To select The Bridge as the AVRs input source: From the front panel, press the Input Source Selector 6 on the front panel as needed. From the main remote, press the Input DMP Selector 3. From the ZR 10 remote, press the TheBridge /DMP Selector.
channel that was last tuned. Press the button again to select between FM, AM and XM. You may also directly select the FM tuner by pressing the Tuner/FM Select Button X down towards the bottom of the remote. To change stations, press the Tuning Up/Down Button M. To select the tuner from the ZR 10 remote, press the Tuner Selector , or for XM Radio press the XM Radio Selector Button (when an optional XM Connect & Play or Passport module is connected and the programming service has been activated). To change the tuning mode, press the Tuning Mode Button 7B. When the button is pressed so that AUTO/ STEREO appears in the Upper Display Line #, each press will put the tuner in a scan mode that seeks the next higher or lower frequency station with acceptable signal strength. An AUTO ST TUNED indication will momentarily appear when the station stops at a stereo FM station, and an AUTO TUNED indication will momentarily appear when an AM or monaural FM station is tuned. Press the Tuning buttons again to scan to the next receivable station. When the button is pressed so that MANUAL/ MONO appears in the Upper Display Line #, each tap of the Selector will increase or decrease the frequency by one increment. When the tuner receives a strong-enough signal for adequate reception, MANUAL TUNED will appear in the Lower Display Line $. Stations may also be tuned directly in either the automatic or manual mode. To enter a stations frequency directly, first select the AM or FM band as shown above. Next, press the Direct Button 8. Within 5 seconds of when DIRECT IN scrolls in the Upper Display Line #, enter the station frequency by pressing the Numeric Keys k. If you press an incorrect button while entering a direct frequency, press the Clear Button 9 to start over. NOTE: When FM reception of a station is weak, audio quality will be increased by switching to Mono mode by switching to the MANUAL/MONO mode. Preset Tuning Using the remote, up to 30 AM or FM stations may be stored in the AVR 645s memory for easy recall, using the front-panel controls or the remote. To enter a station into the memory, first tune the station using the steps outlined above. Then: 1. Press the Memory Button b; the stations frequency will flash.
2. Within 5 seconds, press the Numeric Keys c corresponding to the location where you wish to store this stations frequency. Once entered, the preset number will appear in the Upper Display Line #. 3. Repeat the process after tuning any additional stations to be preset. Recalling Preset Stations To manually select a station previously entered in the preset memory, press the Numeric Keys c that correspond to the desired stations memory location. To manually tune through the list of stored preset stations one by one, press the Preset Buttons 6v on the front panel or the main remote, or the Prev/Next Transport Controls on the ZR 10 remote.

AM/FM Tuner Operation

The AVR 645s AM/FM tuner is capable of tuning AM, FM and FM Stereo broadcast stations. Stations may be tuned manually, or they may be stored as favorite station presets and recalled from a 30-position memory. Tuner and Station Selection The AVR 645s AM/FM tuner may be selected as the units source, and stations changed, by following one of these steps: From the front panel, press the Input Source Selector 6 until the desired tuner frequency band (AM, FM or XM) appears. To change stations within a frequency band, press the Tuning Selection 3. You may also press the front panels Tuner Band Selector 4 to select the tuner. The first press will select the last used frequency band and station. Subsequent presses will change the frequency bands, selecting the last used station or XM program used. Press the Tuning Selection 3 to change stations within a frequency band. From the main remote, press the Tuner/FM Select Button X by pressing the button up towards the top of the remote. The first press of the button selects the frequency band and station or XM

it will appear; or press the button again until XM Radio is heard. Press the Tuning Selector 3 to change stations within a frequency band. Press the Tuning Selector 3 to select a different XM channel. From the main remote, press the Tuner/FM Select Button X by pressing the button up towards the top of the remote as needed until XM Radio is shown as the source. To change stations, press the Tuning Up/Down Button M. To select the tuner from the ZR 10 remote control, press the XM Radio Selector Button. Channels are selected using the Prev/Next 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 AVRs source, the channel number will appear in the Upper Display Line C, 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. The current channels name will normally appear in the Lower Display Line D. For local traffic information, the name of a city will be shown in place of the channel name. You may change this display to show the current artist and track title information by pressing the Tuning Mode Selector 7B. When you are listening to a channel with local traffic information in the 200 series of channel numbers, these buttons change the display to show the temperature and current weather for the selected city. To tune a channel number directly, simply press the Numeric Keys c. Unlike standard AM/FM tuner operation, it is not necessary to press the Direct button first. The AVR 645 has five banks of preset memories for XM Radio, each with eight memory positions and designated by a letter (A through E). To store a channel into a memory group, first press the Set Button F until PRESET SEARCH appears in the Upper Display Line C and on the top line of the semi-OSD display. Next, press the / Navigation Buttons D until the desired preset memory bank letter appears in the Lower Display Line D and in the bottom line of the semi-OSD display. Next, press the Memory Button b and note that a dash will start to flash next to the preset memory bank letter. Within five seconds, press the Numeric Button c from 1 to 8 for the memory slot you wish to use. To tune up or down through a list of channels stored in the currently active preset memory, press the Preset Up/Down Buttons L. You may also use the Preset Station Selector 5 on the front panel, or the Prev/Next Transport Controls on the ZR 10 remote. To change to another preset bank, press the Set Button FI and then press the / Navigation Buttons HD until the desired preset memory bank letter appears in the Lower Display Line D and in the bottom line of the semi-OSD display. Each XM Radio channel is assigned a category, which may be viewed by pressing the Tuning Mode Selector B7. You may search for an XM channel in any of the categories by first pressing the Set ButtonFI and then pressing the / Navigation Buttons HD until the desired category name appears in the Lower Display Line D and in the bottom line of the semi-OSD display. Press the Set Button FI again to start the search for the next channel in that category. Note that you may see a LOADING message, indicating that the XM tuner is downloading content and may not be able to operate. If the message continues to appear, check to see whether the XM antenna is properly positioned toward a south-facing window, experiment with the antenna position, or change to another input and then reselect XM Radio. 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.

Multiroom Setup

Once the audio and IR link connections have been made, the AVR 645 needs to be configured for multiroom operation. To change a setting from its factory default, use the MULTI-ROOM SETUP menu. Press the OSD Button U to call up the MAIN MENU (Figure 1). Next, press the / Navigation Buttons D so that the cursor is next to MULTI-ROOM, then press the Set Button F. When the MULTI-ROOM SETUP menu (Figure 25) appears, follow the instructions shown below to make any needed configuration adjustments.

* MULTI-ROOM SETUP *

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 / Navigation Buttons D so that the cursor is pointing to the SB AMPS line. Press the / Navigation Buttons D so that MULTI is shown in highlighted video. When this change is made, connect the wires feeding the remote zone speakers to the Surround Back/Multiroom Speaker Outputs E. When the SBL/SBR speakers are set for multiroom operation, you may still configure the AVR 645 for 7.1 modes in the main listening room by making certain that the SURR BACK line in the SPEAKER SIZE menu (Figure 20) is set to SMALL or LARGE, as shown in the instructions on page 30. When that is done, the word MULTI will appear next to the large or small designator to alert you to the fact that the internal SBL/SBR amplifiers are assigned to the multiroom system, and that an optional, external two-channel power amplifier must be connected to the SBL/SBR Preamp Outputs in order to use surround back channel speakers.

Once this setting is made, press the / Navigation Buttons D to select another configuration item on this page, or press the OSD Button U if you have completed your adjustments to the Multiroom system. Infrared Output Selection The AVR 645 enables you to select which IR input will be used to feed the Full Carrier IR Output B. The factory default setting is the IR signal that is fed to the Multiroom IR Input N, but you may select other options. To change this setting, first make sure the MULTI-ROOM SETUP menu is on the screen, and then press the / Navigation Buttons D so that the cursor is next to CARRIER OUT; then press the Set Button F. Press the / Navigation Buttons D to select one of these options: ZR 10 feeds the signal present at the Multiroom IR Input N to the Full Carrier IR Output B. A-BUS feeds the signal carried back from an optional A-BUS module connected to the AVR to the Full Carrier IR Output B. FRONT feeds the received through the frontpanel Remote Sensor Window ^ to the Full Carrier IR Output B. When all needed adjustments to the MULTIROOM SETUP menu have been made, press the / Navigation Buttons D until the cursor is pointing to BACK TO MASTER MENU to make changes to other menus, or press the OSD Button U to exit the menu system and return to normal operation. volume, source selection, tuner control or the operation of an iPod docked to The Bridge. If any of the input devices are connected to the IR Output C or Full Carrier IR Output B, by either a hard-wire connection or through an optional IR blaster, you may use the Transport Controls on the ZR 10 to operate compatible Harman Kardon products. To turn the system off from the remote room, press the Power Off Button 0. Remember that the AVR 645 may be turned on or off from the remote room, regardless of the systems operation or status in the main room. NOTE: When XM Radio or the tuner is selected as the source for the remote zone, any change to the frequency or preset will also change the station being listened to in the main room, if the tuner is in use there. Similarly, if someone in the main room changes the station, the change will also have an impact on the remote room. To turn the multiroom system on or off from the room where the AVR is located, press the Multiroom Button Q. When the MULTI ON/OFF message appears in the Lower Display Line $ press the Set Button F and then press the / Navigation Buttons D so that the display changes to MULTI ON or MULTI OFF as desired. , Press the Set Button F again to activate the command. NOTE: The multiroom system will remain on even when the AVR is turned off in the main listening room where it is located. When the AVR 645s multiroom system is turned on, but the unit is in the Standby mode (turned off) in the room where the AVR 645 is located, the light surrounding the front-panel Standby/On Switch 0 will remain blue, rather than amber, and a MULTI-ROOM ON message will be shown in the Lower Display Line D. When the Multiroom system is turned on, the input selected using the Multiroom menu will be fed to the Multiroom Audio Outputs 8 on the rear panel as well as the A-BUS Connector. The volume will be as set in the previous selection, although it may also be adjusted using an optional IR sensor and the ZR 10 remote in the remote location, or the A-BUS keypad, or on the optional audio power amplifier connected to the Multiroom Audio Outputs 8. Although changes to the input source or remote room volume will normally be made using an IR sensor in the remote room that is connected to the AVR, it is also possible to change those settings from the main listening room. This is useful for situations where some or all of the remote rooms do not have an IR sensor, or to take control over the remote room without actually being in that room. To change the input source or volume in the remote zone from the room where the AVR is located, press the Multiroom Button Q. When the MULTI ON/OFF message appears in the Lower Display Line $, press the Set Button F and then press the / Navigation Buttons D so that the display changes to either MULTI INPUT or MULTI LEVEL, depending on which setting you wish to change. Press the Set Button F again and then use the / Navigation Buttons D to change the input or volume. Press the Set Button F one more time to activate the command. Note that the this volume adjustment controls the level for the output to the Multiroom Audio Outputs 8 and for any speakers connected to the Surround Back/Multiroom Speaker Outputs E when the Surround Back amplifier channels are configured for Multiroom use, as shown on page 46. This adjustment does NOT change the volume level for any room where an A-BUS module is used, as that setting is only adjustable using the A-BUS modules volume control or a remote pointed at the A-BUS modules built-in sensor.

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 Selectors 3. 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 remotes Rename function, you can even change the way the name of the device appears on the remotes 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: 1. Press and hold the Program Button O for about three seconds while the message shown in Figure 26 appears in the remotes LCD Information Display 2. Release the button when the red light under the Set Button F appears. 2. The remotes MAIN MENU message (Figure 27), will appear in the LCD and the Set Button F will remain illuminated in red. Press the Navigation Button D twice so that CHANGE DEVICE appears on the bottom line of the LCD screen, as shown in Figure 40. Press the Set Button F to begin the process of reassigning the commands used for a particular device.

MAIN MENU CHANGE DEVICE

4. Once the old device type has been selected, you need to tell the remote which set of remote codes to use as a replacement for the device just selected. When the instructions shown in Figure 48 appear, press the / Navigation Button D to scroll through the list of device categories to find the name of the device that you wish to use. The old device name will remain on the left side of the LCD screen, while the replacement device list will scroll to its right. For example, press the Navigation Button D until the display screen reads TV<-VCR to have the VID 2/TV Button transmit the commands used to control a VCR. Press the Set Button F when the desired device combination appears.

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 remotes LCD screen are customized to reflect the specific characteristics of a playback sources brand name or the new function given to a specific button when one remotes 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. 1. Press and hold the Program Button O for about 3 seconds while the message shown in Figure 26 appears in the remotes LCD Information Display 2. Release the button when the red light under the Set Button F appears. 2. The remotes MAIN MENU message (Figure 27), will appear in the LCD and the Set Button q will remain illuminated in red. Press the / Navigation Button D until RENAME appears on the bottom line of the LCD screen, as shown in Figure 76.

MAIN MENU RENAME

5. At the next menu screen, you will see the device name on the bottom line of the display with a blinking cursor box to the right of the device name. Press the Navigation Button D to 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 c. 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 Navigation Button D to move the blinking cursor block to the next position. Then press the Numeric Key c as required to enter the desired letter. c. To enter a blank space, press the Navigation Button D twice. The first press will move the cursor to the right, and the second press will move the cursor one more space to the right, leaving a blank space between the last letter and the next one.

4. The next display screen (Figure 80) selects the device within which the key to be renamed exists. Press the / Navigation Buttons D until the name of the base device appears. In our example, since we want to rename a button within the DVD device memory, DVD should appear in the lower line of the LCD. When the desired device name appears, press the Set Button F.

SELECT A DEVICE DVD

7. To enter the new name for the key, press the Numeric Keys c. 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. Consult the table on this page to see which characters are available by pressing a particular button. 8. 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 an O, so you would press the 6 button once. b. To enter a letter that uses the same numeric key, you must first press the Navigation Button D to move the blinking cursor block to the next position. Then press the Numeric Key c as required to enter the desired letter. This is the way you would enter the second O in the word ZOOM, and again for the letter M. c. To enter a blank space, press the Navigation Button D twice. The first press will move the cursor to the right, and the second press will move the cursor one more space to the right, leaving a blank space between the last letter and the next one. 9. Repeat Steps 7 and 8 as needed to complete entering the needed letters, numbers, characters and spaces. 10. When the text entry is complete, press the Set Button F. The new name will be entered into the remotes memory, replacing the default name. 11. At this point, you have two options: a. If you wish to program an additional key within the same device, press the Set Button F as instructed by the bottom line of the LCD reading ANOTHER KEY. The remote will return to the SELECT A KEY menu option as shown in Step 6. Repeat the instructions in Steps 6 though 11 to rename the next key.
