System Configuration

Note: These icons are available only when making setup changes without the use of the full OSD mode.

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 listening 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 compen- sate for this difference through the use of the delay settings to adjust the timing for the specific speaker placement and acoustic conditions in your listening room or home theater.

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 inch, as the system is designed to accommodate typi- cal 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 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 per- sonal 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.

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. 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 and surround (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. However, you will need to enter the delay settings separately for each variant mode, such as Dolby Pro Logic II – Music, Dolby Pro Logic II – Game, Dolby Pro Logic, Dolby 3 Stereo.

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-channel surround mode. For the purposes of setting 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 DELAY ADJUST MENU (Figure 9). If the sys- tem is not already at that point, press the OSD button L to bring up the master menu. Press the ¤ Button D three times or until the on- screen cursor is pointing at the MANUAL SETUP line. Press the OK Button F and call up the DELAY ADJUST submenu.

Next move the cursor to the UNIT line and select the unit for distances you prefer to enter, feet or meter. Then move the cursor to the FL line where the first adjustment is made. Now press the / Buttons E until the dis- tance from the front left speaker to the preferred listening position is entered. Next press the

¤Button D once to move to the next line.

Now the cursor will be at the CEN line so that the delay for the center speaker may be set. Press 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 master menu by pressing the /¤ Navigation Button D until the fi cursor is pointing to BACK TO MASTER MENU and then pressing the OK Button F.

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 system.

To adjust the A/V Sync delay, press the /¤ Navigation Button D so that the fi cursor is pointing to the A/V Sync Delay line on the menu 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 OK Button F within five seconds of when the A/V SYNC DELAY message appears in the on-screen display and the Lower Display Line ˜. Then, press the / Navigation Button

Eto enter the desired delay setting that brings the video and sound back in sync. The A/V Sync delay time may be set in 1 millisecond inter- vals up to 180 ms. Press the OK Button F again to enter the setting.

Note that the A/V Sync delay setting is unique to each video input source, so you may enter a different setting to compensate for the differ- ences between any product attached to the Video 1, 2 or 3 inputs.

To change one of the individual speaker positions directly, press the Delay Select Button , followed by the /¤ Navigation Button D to select the desired position as that name appears in the on-screen display and the Main Information Display Ò. When the name of the speaker position to be adjusted appears press the OK Button F within five seconds. Press

the / Navigation Button E to enter

the desired delay setting for that speaker and then press the OK Button F to enter the set- ting. The /¤ Navigation Button D may be used to select another position, or you may simply wait five seconds for the system to time out and return to normal operation.
