System Configuration
Artificially increasing the volume to the rear
speakers may destroy the illusion of an envelop-
ing 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.
When the AVR is configured for 6.1-channel
operation using a single surround back speaker,
the output level adjustments will still provide an
adjustment for separate surround back left and
surround back right positions even though your
system has only one surround back speaker. This
means that the Surround Back channel will seem
to appear twice, and in 6.1 operation this is
normal. The separate SBL/SBR adjustments for
6.1 operation are needed to optimize the balance
between the two discrete channels within the
AVR as they are mixed for output to a single
speaker.
IMPORTANT NOTE: The output level can be
adjusted for each digital and analog surround
mode individually. This allows you to compensate
for level differences between speakers, that may
also vary with the surround mode selected, or to
increase or decrease the level of certain speakers
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
off the OSD system if it is in use.
2. Adjust the volume so that it is at
shown in the on-screen display or Main
Information Display Ò.
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
main menu, press the
on-screen ➞ cursor is next to the
line. If you are not at the main menu,

When the
CHANNEL ADJUST
appears, the test tone is off. Use the
Navigation Button
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
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 25), press the

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.
NOTE: Remember that when your system has
only a single Surround Back speaker and is thus
configured for 6.1-channel operation, you will
hear the test tone twice from the back speaker,
once with the SBL indication and once with the
SBR indication. This is normal, and it allows you
to adjust the output balance for the mixing circuit
that creates a 6.1 output when 7.1 modes such
as Logic 7/7.1 are used.
6. After checking for speaker placement, let the
test noise circulate again, and listen to see
which channels sound louder than the others.
Using the front left speaker as a reference,
press the Buttons
‹ / ›
to bring all speakers to the same volume level.
When one of the buttons is pushed, the
‹ / ›
test noise circulation will pause on the channel
being adjusted to give you time to make the
adjustment. When you release the button, the
circulation will resume after five seconds. The
on-screen cursor ➞ and the test noise can also
be moved directly to the speaker to be
adjusted by pressing the buttons

on the remote.
7. Continue to adjust the individual channels
until the volume level sounds the same from
each speaker. Note that adjustments should be
made with the Buttons

remote only, NOT the main volume controls.
If you are using a sound-pressure level (SPL)
meter for precise level adjustment with the test
tone, open the main Volume Control
-15dB and set the individual output level for each
channel so that the meter reads 75dB,
C-Weighted Slow. After all settings are made turn
the main volume down.
You may also make these same adjustments with
complete manual control over the channel being
adjusted by pressing the Navigation
