Note that the A/V Sync delay setting is unique to
each video input source, so you may enter a dif-
ferent setting to compensate for the differences
between any product attached to the Video 1, 2
or 3 inputs.

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.
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.
If you have already calibrated your system using
EzSet the output level adjustments shown will
, reflect the results of the measurements made by
EzSet. No further changes are needed unless you
wish to change a specific item to reflect your
personal taste or a non-standard system
configuration.
IMPORTANT NOTE: The output level can be

intentionally, depending on the surround mode
selected. Note that adjustments made for any
surround mode are effective with all inputs
associated with the same surround mode.
Before beginning the output level adjustment
process, make certain that all speaker connec-
tions have been properly made. The system
volume should be turned down at first.

For the easiest set-up, follow these steps while
seated in the listening position that will be used
most often:
1. Make certain that all speaker positions have
been properly configured for their "large" or
"small" settings (as outlined above) and turn

3. Select any input associated with the surround
mode for which you want to adjust the output
levels. Remember that the same adjustments
must be made with all other surround modes
you´ve in use.
4. Manual output level adjustment is most easily
done through the
menu (Figure 12). If you are already at the

appears, the test tone is off. Use the

Navigation Button to select any channel
for adjustment using an external source, such as
a test disc, from which to judge the output levels.
After the ➞ cursor is pointing to the channel to
be adjusted, press the / Navigation Button

to raise or lower the output level.
However, before proceeding with any manual
adjustment we recommend that you first use the
AVR's internal test tone generator and automatic
sequencer to send a tone to each channel so that
you may verify that all speaker connections have
been properly made.
5. To turn the test tone on and have it automati-
cally circulate among the channels where a
speaker has previously been configured (see
page 22), press the Navigation

Next, press the / Navigation Button

the test tone will immediately begin to circu-
late clockwise around the room, playing for
two seconds in each speaker before switching
to the next speaker position. The ➞ cursor will
blink next to the active speaker to indicate
which speaker the sound should be coming
from.
IMPORTANT NOTE: Because this test noise will
have a much lower level than normal music, the
volume must be lowered after the adjustment for
all channels is made, but BEFORE you return to
the main menu and the test tone turns off.
NOTE: Remember to verify that the speakers have
been properly connected. As the test noise
circulates, listen to make certain that the sound
comes from the speaker position shown in the
Main Information Display Ò. If the sound
comes from a speaker location that does NOT
match the position indicated in the display, turn
the AVR off using the Main Power Switch 1
and check the speaker wiring or connections to
external power amplifiers to make certain that
each speaker is connected to the correct output
terminal.
6. After checking for speaker placement, let the
test noise circulate again, and listen to see
which channels sound louder than the others.
