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

9

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 AVR5 in the Dolby Pro Logic

mode by pressing the 

*

on the front

panel or by pressing the 

on the remote

until 

PRO LOGIC

appears in the

¯

and the

indicator lights.

2. Press the 

button 

"

Ô

on the remote or front panel. 

The word 

TEST

will appear in the

¯

, and the

letters 

FL

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
AVR5 off and check the speaker
wiring to make certain that each
speaker is connected to the correct
output terminal.

4. After checking for proper speaker

placement and connection, continue
to let the test noise circulate so that
you may judge the output level of
each speaker position to the others. As
you listen to the relative output levels,
use the front left speaker as a refer-
ence, and make a note of which of
the other speakers are louder or softer
than the front left.

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 22.

5. To change the output level, let the test

noise circulate until the channel
requiring adjustment appears in the
Information Display, and then press
the 

‹

›

buttons 

{

to stop the

circulation and raise or lower the
output. For example, using the front
right speaker as a reference, to adjust
the center speaker level, press the

‹

›

buttons 

˜ {

when 

TEST

CTR

appears in the display.

6. During level adjustment, the flashing

speaker position indication will be
replaced with a positive or negative
number to indicate the output offset
from the reference level. Use the

‹

›

buttons 

˜ {

until the level

is equal to the reference, then press
the 

button

Û }

to enter the

setting into the AVR5’s memory. Note
that output level adjustments must be
made within three seconds or the test
noise will begin to circulate.
