SYSTEM CONFIGURATION 31
System Configuration
Figure 12
When the CHANNEL ADJUST menu first
appears, the test tone is off. Use the ⁄ / ¤
Navigation Button E 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
E to raise or lower the output level. However,
before proceeding with any manual adjustment
we recommend that you first use the AVR’s inter-
nal 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.
To turn the test tone on and have it automatically
circulate among the channels where a speaker
has previously been configured (see page 27),
press the
⁄ / ¤ Navigation Button E until
the ➔ cursor is pointing to the
TEST TONE
line on the menu. Next, press the ‹ / ›
Navigation Button E until
AUTO is shown.
This will cause the test tone to circulate, starting
at the Front Left speaker. It will circulate clock-
wise around the room, playing for two seconds in
each speaker before switching to the next speak-
er 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 ˜. 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.
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 E on the remote 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
E on the remote.
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 E on the 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
d to -
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
Button E until the ➔ cursor is pointing to the
TEST TONE line on the menu and then using
the ‹ / › Navigation Button E to select
M A N
in the highlighted video. In the M A N mode, the
test tone will also start immediately, but the tone
will only be moved to another channel by pressing
the
⁄ / ¤ Navigation Button E.When the
manual sequencing mode is active, the tone is
turned off by pressing the
⁄ / ¤ Navigation
Button E until the ➔ cursor is pointing to the
TEST TONE line and the ‹ / › Navigation
Button E is then pressed to select
O F F in the
highlighted video.
The final option for tone adjustment using the
menu system is to not use the internal test tone
at all. To do this, simply use the
⁄ / ¤
Navigation Button E to change the channel
and then use the ⁄ / ¤ Navigation Button
E to change the output level. When making
channel output adjustments without the internal
test tone we strongly recommend that you use a
test disc in the “repeat” mode on your DVD or
CD player so that the signal being used is con-
stant throughout the adjustment process.
NOTE: The subwoofer output level is not
adjustable using the test tone. To change the
subwoofer level, follow the steps for Output Level
Trim Adjustment on page 40.
When all channels have an equal volume level,
the adjustment is complete. Now turn the
Volume
d down to about -40dB, otherwise
the listening level may be too high as soon as the
source’s music starts to play. To exit this menu,
press the
⁄ / ¤ buttons E until the on-screen
› cursor is next to the BACK T O MANUAL
SETUP line, and then press the Set Button
F to return to the
MANUAL SETUP .
The output levels may also be adjusted at any
time using the remote control and semi-OSD sys-
tem. To adjust the output levels in this fashion,
press the Test Button
8. As soon as the
button is pressed, the test tone will begin to
circulate as indicated earlier. The correct channel
from which the test noise should be heard will be
shown in the lower third of the video screen and
in the Main Information Display ˜. While
the test noise is circulating, the proper channel
position will also be indicated in the
Speaker/Channel Input Indicators Ú by a
blinking letter within the correct channel. Turn up
the Volume
d until you can hear the test
noise clearly.
To adjust the output level, press the ⁄ / ¤ but-
tons E until the desired level is shown in the
display or on screen. Once the buttons are
released, the test noise will begin to circulate
again in five seconds.
When all channels have the same output level,
turn the Volume
d down to about -40dB, oth-
erwise the listening level may be too high as
soon as the source’s music starts to play.
Afterwards press the Test Tone Selector
8
button again to turn the test tone off and
complete the process.
IMPORTANT NOTE: The Output level adjust-
ment made will be effective for all inputs, but
only for the actual surround mode selected. To be
effective for any other mode select that mode
(with any input) and repeat the level adjustment
described above. This will also allow you to com-
pensate level differences between speakers, that
may be different with each surround mode, or to
increase or decrease the level of certain speakers
intentionally, depending on the surround mode
selected.
Note: Output level adjustment is not available
for the Surround Off mode, as no surround speak-
ers are used (so level differences between the
speakers in the room cannot occur). But to com-
pensate level differences between stereo and
other surround modes (independently from the
input selected) the outputs can be adjusted with
the Level Trim Adjustment procedure, see page
40, also for the Surround Off (Stereo) modes.
