Output Level Adjustment
Output level adjustment is a key part of the
configuration process for any surround
sound product. It is particularly important
for a Dolby Digital receiver such as the
AVR35RDS, 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
7
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 AVR35RDS in the Dolby Pro
Logic mode by pressing the
Dolby
Pro Logic Selector
Ó
on the
front panel or by pressing the
Surround Mode Selector
g
on
the remote, followed by the
⁄
/
¤
buttons
h
until
PRO LOGIC
appears in the
Main Information
Display
S
and the
PRO LOGIC
indicator
F
lights.
2. Press the
Test Tone
button
Ò
on the remote or front panel. The
words
T -T FL 0dB
will appear
in the
Main Information Display
S
, 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
AVR35RDS 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 (
FL
in the display) speaker
as a reference, press the
⁄
/
¤
buttons
h
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
h
on the remote or the
Selector
buttons
¸
on the front
panel only, NOT the main volume
controls. Then press the
Set
button
j ˜
to memorize the change. If
you are using a sound pressure (SPL)
meter for precise level adjustment, set
the volume so that the meter reads
75dB, C-Weighting Slow.
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 27.
6. When you have adjusted the outputs
so that all channels have the same
level, press the
Test Tone
button
Ò
on the remote or front panel
to complete the adjustment.
