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

on the remote to bring all speakers

to the same volume level. When the

Navigation

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

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

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

CHANNELADJUST

menu is on the

screen, following the instructions shown above, and

then press the

until the cursor is on the

line. Next,

press the

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

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.

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

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.

The output levels may also be adjusted at any time

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

will also be indicated in the

Speaker/Channel

by a blinking letter within

the correct channel.

To adjust the output level, press the

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

that after turning the EzSet/EQ settings back on you

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

OSD Button

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/OUTSETUP

line on the

MASTERMENU

(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
