SYSTEM CONFIGURATION
connected to the correct output terminal, turn the
AVR 645 back on and return to this menu to resume
the channel adjustment procedure. If any speaker con-
nections were changed we also recommend that you
rerun EzSet/EQ before making any manual calibration
adjustments.
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 /
‹ ›
Button n© on the remote to bring all speakers
to the same volume level. When the /
‹
Button n© 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.
Continue to adjust the individual channels until the
volume level sounds the same from each speaker.
Adjustments should be made with the
‹
Button n© on the remote control only, NOT
the main volume controls. If you are using a sound-
pressure level (SPL) meter for precise level adjustment,
set the volume so that the meter reads 75dB,
C-Weighting Slow.
When all channels have an equal volume level, the
adjustment is complete. To exit this menu, press the
Navigation Button n© until the cursor
⁄ / ¤
is next to the BACK TO MANUAL SETUP
line, and then press the Set Button pœ to
return to the MANUAL SETUP menu.
In addition to having the test tone circulate automati-
cally, you may also turn the test tone on, but advance
it from one channel to the next manually. This allows
you to make calibration adjustments, but to have more
control over the way the test tone is moved among
the channels.
To change the tone manually, first make certain that
the CHANNEL ADJUST menu is on the
screen, following the instructions shown above, and
Navigation Button n©
then press the ⁄ / ¤
until the cursor is on the TEST TONE line. Next,
‹ ›
Navigation Button n© until
press the /
MANUAL appears. This will start the test tone from
the front left speaker position but, rather than circulat-
ing to the next channel every five seconds as is the
case in the automatic mode, you must press the
Navigation Button n© to change the
/
⁄ ¤
channel the test tone is being sent to. When you have
circulated through all channels the test tone will stop,
but you may restart it by returning to the TEST
TONE line again and activating manual sequencing.
34 SYSTEM CONFIGURATION
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
n© to change the channel and then use the
Navigation Button n© 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
constant throughout the adjustment process.
Navigation
The output levels may also be adjusted at any time
Navigation using the remote control and semi-OSD system. To
›
adjust the output levels in this fashion, press the Test
Button f. 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 Lower Display Line $. While the
test noise is circulating, the proper channel position
/ Navigation
›
will also be indicated in the Speaker/Channel
Input Indicators @ by a blinking letter within
the correct channel.
To adjust the output level, press the
Button n© until the desired level is shown in
the display or on the 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, press the Test Button f again to complete
the process.
NOTE: Output level adjustment with the test tone is
not available in the Surround Off modes.
In addition to the controls for selecting channels and
the test tone operation, the settings on this menu
also allow you to reset the level settings to either the
factory default of 0dB or to reestablish the settings
that were entered by running EzSet/EQ.
To reset all channel levels to 0dB, press the
Navigation Button n© so that the cursor is
pointing to the LEVEL RESET line and then
press the /
⁄ ¤
so that ON appears in highlighted video.
To return to the settings established by EzSet/EQ,
even if you have made manual changes to the output
trims using the steps shown above, press the
Navigation Button n© so that the cursor is
pointing to the EZSET SETTINGS line and
‹
then press the
once so ON appears in highlighted video. Remember
that after turning the EzSet/EQ settings back on you
must return to this menu line and change the
setting to OFF if you wish to make any manual
trim adjustments.

The final setting in this menu enables you to have the
output levels remain the same for all inputs or to be
adjusted differently for each (or any) input. While most
listeners prefer to keep the same output levels for all
sources, you may wish to raise or lower some channels,
particularly the subwoofer output for a specific source
such as a CD that is primarily used for music playback.
To enter individual settings for a specific channel, first
make sure that you have either run EzSet/EQ and/or
made any desired manual trim adjustments to set a
baseline for all channels. After that is done, press the
∫ to exit the menu system and
OSD Button
then select the input for which you wish to enter differ-
ent level settings by using either the Input Source
Selector 7 on the front panel or the buttons
on the remote that are used to select an input
source de ç∂≠ƒ®. Next,
return to the CHANNEL ADJUST submenu
using the steps outlined above.
At the CHANNEL ADJUST menu, press
Navigation Button n© until the cursor
⁄ / ¤
is pointing to the LEVEL TRIM line and then
Navigation Button n© once
‹ ›
press the /
so that INDEPENDENT appears in highlighted
video. When this setting is active you may change the
channel output levels for any input without changing
the settings previously established for another.
When all changes to the Channel Output levels and
the associated level trim settings have been made,
Navigation Button n© until
press the ⁄ / ¤
the cursor is on the BACK TO MANUAL
SETUP menu and then pressing the Set Button
pœ so that you may make any other adjust-
ments to the system parameters. If the changes just
made complete the manual adjustments needed,

press the OSD Button
system and resume normal system operation.
Additional Input Adjustments
After one input has been adjusted for Surround mode,
digital input (if any), speaker type, and output levels,
go back to the IN/OUT SETUP line on the
MASTER MENU (Figure 1) and enter the set-
tings for each input that you will use. In most cases,
only the digital input and surround mode will be differ-
ent from one input to the next, while the speaker type,
crossover frequency, Night mode and output level
settings will usually be the same and may be quickly
entered by entering the same data used for the
original input.
Once the settings outlined on the previous pages have
been made, the AVR 645 is ready for operation. While
there are some additional settings to be made, these
are best done after you have had an opportunity to
