System Configuration

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 SUR- ROUND 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 DF to make your selection. When the desired setting appears, press the /¤ Navigation Button DF 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 OK/Enter Button E on the TC 30 or the Set Button Q to continue with overall configuration.

Subwoofer Configuration

The AVR 745 is among the very few A/V receivers or surround processors that are capable of feeding two subwoofers, as well as the standard configuration of a single subwoofer. Although one subwoofer is capable of delivering powerful bass, the use of two subwoofers in conjunction with EzSet/EQ II expands the bass response over a wider listening area.

The default setting for the AVR 745 is a single subwoofer, but if you are using two subwoofers, it is important to change the setting on the NO. SUBS line. To do that, press the /¤ Navigation Button DF as needed so that the cursor is pointing to NO. SUBS, and then press the /Navigation Button DF so that the number shown changes from 1 to 2.

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 II 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 27) is on the screen; then press the /¤ Navigation Button DF so that the cursor is pointing to SUB SIZE and then press the /Navigation Button DF to begin the selection process. Note that a warning message will appear for 4 seconds to remind you to rerun EzSet/EQ II 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 sys- tem. 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 DF until the cursor is on the BACK TO MANUAL SETUP menu and then pressing the OK/Enter Button E on the TC 30 or the Set Button Q so that you may make any other adjustments to the system parameters. It is also important to remember to rerun the EzSet/EQ II system if any changes have been made to the settings on this menu, follow- ing the instructions shown on page 36 for using the Manual mode.

The speaker configuration settings may also be adjusted directly and without going into the OSD menu system at any time using the TC 30 remote control. To adjust the speaker settings, first press the Devices Button 4 on the TC 30, and then press the Screen Button 6 at the top of the left vertical row, to the right of the AVR image on the remote’s screen. When the images in the LCD change, press the Screen Button

6next to the box with the word SPEAKER. Immediately press the /Navigation Button DF until the desired speaker position’s name appears in the Lower Display Line ˜, and in the semi-OSD message, if the video in use is a 576i source.

Within five seconds of stopping at the desired speaker position, press the OK/Enter Button

Eon the TC 30 or the Set Button Q. Use the /Navigation Button DF to select the desired setting and then press the OK/Enter Button E on the TC 30 or the Set Button Q again to enter the setting into the system memory.

To assist in making these settings, the icons in the Speaker/Channel Input Indicators Ú will change as the speaker type is selected at each position. When only the inner icon box is lit, the speaker is set for “small.” When the inner box and the two outer boxes with circles inside them are lit, the speaker is set for “large." When no indicator appears at a speaker location, that position is set for “none” or “no” speaker.

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 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.

If you have already calibrated your system using EzSet/EQ II the delay settings shown will reflect the results of the measurements made by EzSet/EQ II. 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 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.
