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

F again

until the cursor is on the

TEST TONE line and

then press the

‹

›

Navigation Button

F 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

F 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

F 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

F 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

-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

F until the ➞ cursor is pointing to

the

TEST TONE line on the menu and then

using the

‹

›

Navigation Button

F to

select

MAN in the highlighted video. In the MAN

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

F until the ➞ cursor

is pointing to the

TEST TONE line and the

‹

›

Navigation Button

F is then pressed

to select

OFF 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

F to change the

channel and then use the

⁄

Navigation

Button

F 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

signal being used is constant 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 46.

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

F until the

on-screen ➞ cursor is next to the

BACK TO

MANUAL SETUP

line, and then press the

Set Button

Q 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

. 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

by a blinking

letter within the correct channel. Turn up the

Volume

until you can hear the test noise

clearly.

To adjust the output level, press the

⁄

but-

tons

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.

IMPORTANT NOTE: The Output level

adjustment 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 compensate 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

speakers are used (so level differences between

the speakers in the room cannot occur). But to

compensate 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

46, also for the Surround Off (Stereo) 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 re-estab-

lish the settings that were entered by running

Ezset/EQ.

To reset all channel levels to 0dB press

⁄

Navigation Button

F so that the cursor

is pointing to the

LEVEL RESET line and

then press the

⁄

Navigation Button

F once so ONappears in highlighted

video.
