SYSTEM CONFIGURATION

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

menu to trim

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

EZSET/EQ

MAIN

menu (Figure 12) is on the screen. Press

the

⁄

Navigation Button

to move

the cursor next to

CHANNEL ADJUST

and

then press the

OK/Enter Button

on the TC

30 or the

Set Button

on the ZR 10 remote

control. The

CHANNEL ADJUST

(Figure 30) will appear on the screen.

Figure 30

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
automatically circulate among the active
channels or to only move from one channel to
the next on your command. When the

CHANNEL ADJUST

menu appears, we

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

⁄

Navigation Button

again

until the cursor is on the

TEST TONE

line and

then press the

‹

›

Navigation Button

until

AUTO

is in highlighted video. The

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

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 circula-

tion 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.

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

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

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

until the

➞

cursor is pointing to

the

TEST TONE

line on the menu and then

using the

‹

›

Navigation Button

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

When the manual sequencing mode is active, the
tone is turned off by pressing the

⁄

Navigation Button

until the

➞

cursor

is pointing to the

TEST TONE

line and the

‹

›

Navigation Button

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

to change the

channel and then use the

⁄

Navigation

Button

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

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

until the

on-screen

➞

cursor is next to the

BACK T O

MANUAL SETUP

line, and then press the

OK/Enter Button

on the TC 30 or the

Set

Button

to return to the

MANUAL

SETUP

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

on the TC 30, and

then press the

Screen Button

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
LCD change, press the

Screen Button

to the box with the word
