SYSTEM CONFIGURATION When there are no speakers available at a specific position, select NONE. When this option is chosen for the Center or Side Surround speakers, the sound that would normally be sent to these channels will be split between the front left and right speakers. Note that when your system does not include Center or Surround speakers, the use of Dolby Virtual Speaker as a surround mode may provide a sound field that simulates the presence of these speakers. (See the appendix for more information on the Dolby Virtual Speaker mode.) Note that when NONE is selected for the Back Surround speakers, the 6.1/7.1 channel surround modes are not available. When this is the case for your system, you may wish to take advantage of the availability of the unused amplifier channel pair to power a second set of speakers in another room. (See page 44 for more information on amplifier configuration.) Once any desired changes have been made to the speaker size and/or crossover, press the ⁄/¤ Navigation Button n© to move the cursor to any other line on this menu to make a setting change, or go to the BACK TO MANUAL SETUP menu and then press the Set Button pœ to continue with overall configuration. LFE Low-Pass-Filter Setting The LFE LP FLT line selects the frequency setting below which sounds that may be available from a special low-frequency effects (LFE) track are sent to the subwoofer. In most cases, this setting will be set accurately by EzSet/EQ but, should you wish to make a change from that setting or the 120Hz frequency that is most commonly used in the creation of LFE channels by motion picture sound mixers, after making sure that the SPEAKER SIZE menu (Figure 18) is on the screen, press the ⁄/¤ Navigation Button n© so that the cursor is pointing to LFE LP FLT. Press the ‹/› Navigation Button n© to begin the selection process, and note that a warning message will appear, reminding you to rerun EzSet/EQ after all changes have been made. When the SPEAKER SIZE menu returns to the screen, 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 pœ to continue with overall configuration. Sub Mode Setting When the Front Left/Right speakers are configured as "Large" and a subwoofer is detected by EzSet/EQ 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 18) 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 a warning message 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 pœ 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 18) 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 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 subwoofer's 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 pœ 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 26. 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 445 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 digital video recorders. With proper adjustment of the setting for A/V Sync Delay, you can eliminate the loss of lip sync that may be introduced when video signals are digitized. 30 SYSTEM CONFIGURATION
