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 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

the ➔ cursor is pointing to the
line on the menu. Next, press the /
Navigation Button until
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
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 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

Continue to adjust the individual channels until

speaker. Note that adjustments should be made

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

channel so that the meter reads 75dB, C-

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
and then use the
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.
