SYSTEM CONFIGURATION 19

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

to bring up the

MASTER

; press the

Button

and then the

Set Button

to bring up the

SURROUND

SETUP

menu, and then press the

Button

once.

If the Dolby Digital mode is selected, the

›

cursor will

stop at the

CENTER DELAY

line. In that case,

press the

‹

›

Buttons

until the number

calculated using the formula shown above appears in
the display. When the

CENTER DELAY

entered, press the

Button

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

until the number calculated using

the formula shown above appears in the display. When
the delay settings are complete, press the

Button

once 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

or remote

, followed by a press of the

Set Button

. Next, press the

⁄

on the remote or the

Selector Buttons

on the front panel until the desired figure appears in the

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

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

. 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

. Press the

⁄

Buttons

within

three seconds to select the desired setting.

When all settings for the surround setup have been
made, press the

⁄

Buttons

so that the

cursor is next to

RETURN TO MENU

, and

press the

Set Button

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

to bring up

the

MASTER MENU

(Figure 1), and then press

the

Button

twice so that the cursor is on the

SPEAKER SETUP

line. At this point, press the

Set Button

to bring up the

SPEAKER

SETUP

menu (Figure 5).

Figure

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

so that either

LARGE

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

on the remote to

move the cursor to
