System Configuration
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 the delay settings shown will reflect the
results of the measurements made by Ezset/EQ.
No further changes are needed unless you wish
to change an item to reflect your taste or a non-
standard system configuration. To change the
settings, follow the instructions below to enter
the distance between the speaker's location and
your main listening position. The measurements
need not be accurate to the inch, as the system is
designed to accommodate typical listening rather
than a specific "sweet spot" position.
The Delay setting for all speakers configured for
your system will be available only (with 5.1 or
with 6.1/7.1 configuration) when any Dolby sur-
round mode is selected (except Dolby-3-Stereo).
In addition they are selectable with these modes
only, with all other modes the delay times are
fixed. Note that the Delay settings are "Global"
for all inputs, using those Dolby modes, and need
not to be repeated with any input.
To view or change the current delay settings,
make sure the

Output Level Adjustment

Output level adjustment is a key part of the
configuration of any surround-sound product. It
is particularly important for a digital receiver such
as the AVR, as correct outputs ensure that you
hear sound tracks with the proper directionality
and intensity.
In most cases, you will not need to make any
adjustments to the output level, as the settings
made by running Ezset/EQ are as accurate as
those made manually. However, you are able to
use the
menu to trim
CHANNEL ADJUST
the settings to suit your personal preferences or
to configure the system so that the output set-
tings are different from one input source to
another. The ability to make individual output
level adjustments on a per-input basis is useful
for listeners who may prefer different settings for
the subwoofer or an individual channel group
such as the front speakers when playing musical
selections via the CD input as opposed to the
movie soundtracks more frequently used with the
DVD input. This menu also allows you to adjust
the output levels using external sources such as a
test disc or other program material that you use
as a standard, rather than the system's test tone.
NOTE: Listeners are often confused about the
operation of the surround channels. While some
assume that sound should always be coming
from each speaker, most of the time there will be
little or no sound in the surround channels. This
is because they are only used when a movie
director or sound mixer specifically places sound
there to create ambience, a special effect or to
continue action from the front of the room to
the rear. When the output levels are properly
set, it is normal for surround speakers to
operate only occasionally. Artificially increasing
the volume to the rear speakers may destroy the
illusion of an enveloping sound field that
duplicates the way you hear sound in a movie
theater or concert hall.
Before beginning the output level adjustment
process, make certain that all speaker
connections have been properly made. The
system volume should be turned down at first.
To view or change the current Channel Output
settings, make certain that the
