System Configuration
In most cases, you will not need to make any
adjustments to the output level, as the settings
made by running EzSet/EQ are as accurate as
those made manually. However, you are able to
use the
CHANNEL ADJUST
the settings to suit your personal preferences or
to configure the system so that the output set-
tings are different from one input source to
another. The ability to make individual output
level adjustments on a per-input basis is useful
for listeners who may prefer different settings for
the subwoofer or an individual channel group
such as the front speakers when playing musical
selections via the CD input as opposed to the
movie soundtracks more frequently used with the
DVD input. This menu also allows you to adjust
the output levels using external sources such as a
test disc or other program material that you use
as a standard, rather than the system's test tone.
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 dupli-
cates the way you hear sound in a movie theater
or concert hall.
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.
To view or change the current Channel Output
settings, make certain that the
menu (Figure 12) is on the screen. Press

To provide the maximum flexibility, channel
output level adjustments may be made either
with or without the internal test tone, and when
the tone is in use, it may be programmed to
menu to trim automatically circulate among the active
channels or to only move from one channel to
the next on your command. When the
CHANNEL ADJUST
recommend that you first run the test tone once
in the automatic mode to verify that the speakers
have been properly connected. To do this, press
the
⁄ / ¤
until the cursor is on the
then press the
DF until
test tone will then circulate among all channels
for five seconds at each position.
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 DF on the remote to bring all
speakers to the same volume level. When one of
EZSET/EQ
the buttons is pushed, the test noise circula-

tion will pause on the channel being adjusted to
give you time to make the adjustment. When you
and
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
menu
speaker to be adjusted by pressing the
buttons DF on the remote.
Continue to adjust the individual channels until

at all. To do this, simply use the

channel and then use the Navigation

Button DF to change the output level.
When making channel output adjustments with-
out the internal test tone we strongly recom-
mend that you use a test disc in the "repeat"
mode on your DVD or CD player so that the sig-
nal being used is constant throughout the adjust-
ment 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 51.
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

The output level settings may also be adjusted
directly (without going into the OSD menu
system) at any time, using the TC 30 remote
control. To adjust the speaker settings, first press
the Devices Button 4 on the TC 30, and
then press the Screen Button 6 at the top of
the left vertical row, to the left of the AVR image
on the remote's screen. When the images in the
