Output Level Adjustment

Output level adjustment is a key part of
the configuration process for any sur-
round sound product. It is particularly
important for a Dolby Digital receiver
such as the AVR45, as correct outputs will
ensure that you hear sound tracks in their
proper place with the proper intensity.

IMPORTANT NOTE:

Many 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 ambiance, an 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 rear/
surround speakers to operate only
occasionally. Artificially increasing the
volume to the rear speakers may destroy
the illusion of an enveloping sound field
that duplicates the way you hear sound
in a movie theater or concert hall.

Before beginning the adjustment process
make certain that all speaker connections
have been properly made. The system
volume should be set to the level that
you will use during a typical listening
session. Finally, make certain that the

Balance Control

is set to the center

“12 o’clock” position.

To adjust and calibrate the output levels,
follow these steps. For accurate calibration,
it is a good idea to make these adjustments
from the location in your room that is
your favorite listening position:

1. Put the AVR45 in the Dolby Pro Logic

mode by pressing the

Dolby Pro

Logic Selector

on the front

panel or by pressing the

Surround

Mode Selector

on the remote,

followed by the

⁄

buttons

until

PRO LOGIC

appears in the

Main Information Display

and

the

PRO LOGIC

indicator

lights.

2. Press the

Test Tone

button

e Ò

on the remote or front panel. The
words

T -T FL 0dB

will appear

in the

Main Information Display

, and the letters

will flash once

each second.

3. At this point, the test noise will begin

to circulate among all the speakers in
a clockwise rotation.

NOTE:

This is a good time 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 from a speaker
location does NOT match the position
indicated in the display, turn the
AVR45 off and check the speaker
wiring to make certain that each
speaker is connected to the correct
output terminal.

4. 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 (

in the display) speaker

as a reference, press the

⁄

buttons

on the remote or the

Selector

buttons

on the front panel on

each channel to begin to bring them
to the same level. Note that 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.

5. Continue to adjust the individual

speakers until they all have the same
volume. Note that adjustments
should be made with the

⁄

buttons

on the remote or the

Selector

buttons

on the front

panel only, NOT the main volume
controls. Then press the

Set

button
