System Configuration
As an example, in the Figure below, all speakers are set for “large,” and a subwoofer is set.
Delay Settings
Due the different distances between the listen- ing position for the front channel speakers and the surround speakers, the amount of time it takes for sound to reach your ears from the front or surround speakers is different. You may com- pensate for this difference through the use of the delay settings to adjust the timing for the specific speaker placement and acoustic condi- tions in your listening room or home theater.
If you have already calibrated your system using EzSet/EQ the delay settings shown will reflect the results of the measurements made by EzSet/EQ. No further changes are needed unless you wish to change an item to reflect your taste or a nonstandard system configuration. To change the settings, follow the instructions below to enter the distance between the speak- er’s location and your main listening position. The measurements need not be accurate to the centimeter, as the system is designed to accom- modate typical listening rather than a specific “sweet spot” position.
In addition to adjusting the delay time for each individual speaker position, the AVR is among the few A/V receivers that allows you to adjust the delay for the combined output of all speak- ers 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 pro- cessing in products such as digital video dis- plays, video scalers, digital cable or satellite sys- tems, 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.
Although EzSet/EQ calculates the delay settings for the individual speaker positions with very accurate results, the setting for A/V Sync Delay may only be done manually, since it requires that you observe the program material on your video display while adjusting the delay, if any, required for the specific source. Thus, even though you may have used EzSet/EQ for other delay settings, the A/V Sync Delay should still be configured as outlined below.
To re-synchronize the front, center and surround channels at first measure and note the distance from the listening/viewing position to the front, center, surround and surround back (if any) speakers in meters.
Due to the differences in the way each surround mode operates, the delay settings must be established individually for each surround mode. However, once the delay settings are configured for the version of the surround mode with the most channels, they need not be entered again for a version of that mode with fewer channels. For example, once the delay settings are estab- lished for Dolby Pro Logic IIx – Movie, they will be carried over to Dolby Pro Logic II – Movie mode. However, you will need to enter the delay settings separately for each variant mode, such as Dolby Pro Logic IIx – Music, Dolby Pro Logic IIx – Game, Dolby Pro Logic, Dolby 3 Stereo and Dolby Digital EX.
Delay times are adjustable for all surround modes. Although all channels will appear on screen with the default or previously entered dis- tances, the menu system will only allow you to adjust the settings for those channels which are actually used by the current surround mode. For example, when you are listening to music CDs using the CD input in DSP Surround Off mode, you may adjust the delay settings for the front left, front right and subwoofer channels only. The cursor will simply skip the other channels as you navigate through the menu. Therefore, the first time you adjust the delay settings, it is recom- mended that you select a 5.1-, 6.1- or 7.1-chan- nel surround mode, depending on the number of speakers in your system. For the purposes of set- ting the delay distances, the Logic 7 modes allow access to the settings for all channels without requiring that you play a source.
To start with the delay settings at first select the SPEAKER SETUP - Delay (Figure 28). If the system is not already at that point, press the OSD button L to bring up the main menu. Press the ¤ Button D twice or until the Speaker -tab is highlighted in white. Press the Set Button F twice, followed by the ¤ Button D until the Delay Adj -line is highlighted in blue. Press Set F to access the menu.

Next move the blue bar down to the Unit line, press Set F and select the unit for dis- tances you prefer to enter, feet or meter with the use of the ‹ / › Buttons E . Then move the blue bar to the Front Left line where the first adjustment is made, and press the Set Button F. Now press the ‹ / › Buttons
Euntil the distance from the front left speaker to the preferred listening position is entered followed by the Set Button F to confirm your choice. Next press the ¤ Button D once to move to the next line.
Now the blue bar will highlight the Center -line so that the delay for the center speaker may be set. Press Set F followed by the the
‹/ › Buttons E until the distance from the main listening position to the center speaker is entered. Repeat the procedure for all active speaker positions by pressing the ¤ Button D again and use the ‹ / › Buttons E
to change the setting. Remember that this last adjustment will only be needed when you have surround back speakers installed and Dolby Digital chosen as the surround mode.
When the delay time for all speaker positions has been set you may return to the main menu by pressing the ‹ Navigation Button E several times.
However, if you have a digital video source or a digital video display that causes lack of lip sync you may use the A/V Sync adjust feature to delay the audio signal as it is sent to all channels (as opposed to the individual settings) so that the picture and sound are brought back together. We recommend that this adjustment be made using the direct access controls on the remote, as shown below. That enables you to see the image while making the adjustment; however, you may also adjust it here using the menu sys- tem.
To adjust the A/V Sync delay, press the ⁄/¤ Navigation Button D so that the blue bar is highlighting the AV Sync Delay -line on the menu, followed by the Set Button F, and then press the ‹ / › Navigation Button
Eto delay the sound sufficiently so that it matches the on-screen video.
The delay settings may be adjusted at any time using the remote control and while viewing an on-screen image by pressing the Delay Select Button . The A/V Sync Delay setting is first, and it may be adjusted by pressing the Set Button F within five seconds of when the A/V SYNC DELAY message appears in the on-screen display and the Lower Display Line M. Then, press the ⁄/¤ Navigation Button
Dto enter the desired delay setting that brings the video and sound back in sync. Press the Set Button F again to enter the setting.
