center channel speaker more critical. To calculate the delay for the center channel, measure the distance from the preferred listening position in the center of the room to both the center channel speaker and either the left or right speaker.
If the distances are equal, no further adjustment is required and the center delay should be set to zero. If the distance to the front speakers is greater than the distance to the center speaker, you may wish to reposi- tion the speakers by moving the front left and front right speakers closer to the listening position or the center speaker further away from the listening position.
If repositioning of the speakers is not possible, adjust the center delay time, adding one millisecond of center channel delay for every foot closer to the listening position the center speaker is than the front speakers. For example, if the front left and front right speakers are each 10 feet from the listening position and the center channel speaker is eight feet away, the delay is figured as 10–8=2, suggesting an optimal center delay of two milliseconds.
To set the delay time for a specific input, continue within the SURROUND SETUP (Figure 4) menu. If the system is not already at that point, press the OSD Button v to bring up the MASTER MENU; press the ¤ Button q and then the Set Button o to bring up the SURROUND SETUP menu, and then press the ¤ Button q once.
If the Dolby Digital mode is selected, the › cursor will stop at the CENTER DELAY line. In that case, press the ‹/› Buttons n 31 until the number calculated using the formula shown above appears in the display. When the CENTER DELAY is entered, press the ¤ Button q once to move to the next line.
When the CENTER DELAY is set, or if the Dolby Pro Logic II mode is selected, the › cursor will be at the SURR DELAY line so that the delay for the surround speakers may be set. Press the ‹/› Buttons n 31 until the number calculated using the formula shown above appears in the display. When the delay settings are complete, press the ¤ Button
qonce to move to the next line.
Note that the delay settings may also be adjusted at any time when the Dolby Digital or Dolby Pro Logic II modes are in use by pressing the Delay Button on the front panel Ò or remote 30 , followed by a press of the Set Button 21 o. Next, press the ⁄/¤ Buttons mq on the remote or the Selector Buttons 5 on the front panel until the desired figure appears in the Main Information Display S.
Night Mode Settings
The Night mode is a feature of Dolby Digital that uses special processing to preserve the dynamic range and full intelligibility of a movie soundtrack, particularly the dialogue, while reducing the peak level. This prevents abruptly loud transitions from disturbing others, without reducing the sonic impact of a digital source. Note that the Night mode is only available when specially encoded Dolby Digital signals are played.
To adjust the Night mode setting for an input from the menu, make certain that the › cursor is on the NIGHT line of the SURROUND SETUP menu (Figure 4). Next, press the ‹/› Buttons
n31 to choose among the following settings, as they appear in the on-screen display:
OFF: When OFF is highlighted, the Night mode will not function.
MID: When MID is highlighted, a mild compres- sion will be applied.
MAX: When MAX is highlighted, a more severe compression algorithm will be applied.
We recommend that you select the MID setting initially and change to the MAX setting later, if desired.
Note that the Night mode may be adjusted directly any time that a Dolby Digital source is playing by pressing the Night Button k. When the button is pressed, the phrase D-RANGE will appear in the lower third of the video screen and in the Main Information Display S. Press the ⁄/¤ Buttons mq within three seconds to select the desired setting.
When all settings for the surround setup have been made, press the ⁄/¤ Buttons mq so that the
›cursor is next to RETURN TO MENU, and press the Set Button o to return to the main menu.
Speaker Setup
This menu tells the AVR 225 which type of speakers are in use. This is important as it adjusts the settings that determine which speakers receive low-frequency (bass) information. For each of these settings use the LARGE setting if the speakers for a particular position are traditional full-range loudspeakers that are capable of reproducing sounds below 100Hz. Use the SMALL setting for smaller, frequency-limited satellite speakers that do not reproduce sounds below 100Hz. Note that when “small” speakers are used, a subwoofer is required to reproduce low-frequency sounds. Remember that the “large” and “small” descriptions do not refer to the actual physical size of the speakers, but to their ability to reproduce low- frequency sounds. If you are in doubt as to which
category describes your speakers, consult the specifications in the speakers’ owner’s manual, or ask your dealer.
If you haven’t done so previously, place the AVR 225 in Dolby Pro Logic II – Movie mode by using the SURROUND SETUP menu (Figure 3) as described on page 18. It is easiest to enter the proper settings for the speaker setup through the SPEAKER SETUP menu (Figure 5). If that menu is not already on your screen from the prior adjustments, press the OSD Button v to bring up the MASTER MENU (Figure 1), and then press the ¤ Button q twice so that the cursor is on the SPEAKER SETUP line. At this point, press the Set Button o to bring up the SPEAKER SETUP menu (Figure 5).

When the SPEAKER SETUP menu first appears, the on-screen cursor › will be at the top of the list of speaker positions, pointing toward the LEFT/RIGHT line, which sets the configuration for the front left and right speakers. If you wish to make a change to the front speakers’ configuration, press the ‹/› Buttons n 31 so that either LARGE or SMALL appears, matching the type of speakers you have at the left-front and right-front positions, as described by the definitions shown in the preceding section.
When SMALL is selected, low-frequency sounds below 100Hz will be sent only to the subwoofer output. Note that if you choose this option and there is no sub- woofer connected, you will not hear any low-frequency sounds from the front channels.
When LARGE is selected, a full-range output will be sent to the front left and front right outputs. Depending on the choice made in the SUBWOOFER line in this menu, bass information may also be directed to the front left/right speakers, a subwoofer or both.
When you have completed your selection for the front channel, press the ¤ Button q on the remote to move the cursor to CENTER.
