active speaker for that location.

Output Level Adjustment

Output level adjustment is a key part of the configura-
tion of any surround sound product. It is particularly
important for a digital receiver such as the AVR 645,
as correct outputs ensure that you hear soundtracks
with the proper directionality and intensity.
In most cases, you will not need to make any
adjustments to the output level, as the settings
made by running EzSet/EQ are as accurate as those
made manually. However, you are able to use the
CHANNEL ADJUST menu to trim the settings
to suit your personal preferences or to configure the
system so that the output settings are different from
one input source to another.
The ability to make individual output level adjustments
on a per-input basis is useful for listeners who may
prefer different settings for the subwoofer or an indi-
vidual channel group such as the front speakers when
playing musical selections via the CD input as
opposed to the movie soundtracks more frequently
used with the DVD input. This menu also allows you to
adjust the output levels using external sources such as
a test disc or other program material that you use as a
standard, rather than the system's test tone.
IMPORTANT NOTE: 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 ambi-
ence, a special 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 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, even
when making manual adjustments.
SYSTEM CONFIGURATION SYSTEM CONFIGURATION
Before beginning the output level 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.

We recommend that EzSet/EQ be used when the AVR
is first installed to establish the initial level settings.
To make any changes to the channel output settings,
go to the CHANNEL ADJUST sub-menu
within the MANUAL SETUP menu (Figure 18).
To do this, first press the OSD Button
that the MASTER MENU (Figure 1) appears.
Next, press the
until the cursor is on the EZSET/EQ line on the
menu in use and press the Set Button pœ.
∫ to exit the menu Navigate to EZSET/EQ MANUAL
SETUP and press the Set Button pœ. In
the MANUAL SETUP menu, press the
Navigation Button n© again until the cursor is
on the CHANNEL ADJUST line and press the
Set Button pœ to view the CHANNEL
ADJUST menu (Figure 22).

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 first appears we recommend that
you always run the test tone once the automatic mode
to verify that the speakers have been properly con-
nected. To do this, press the
n© again until the cursor is on the TEST
TONE line and then press the
Button n© until AUTO is in highlighted video.
This will cause the test tone to circulate among all of
the channels for five seconds at each position.
As the test tone circulates, the cursor will flash and
move next to each position to indicate where the tone
should be coming from. If the tone is coming from a
different speaker than the one indicated on the menu
screen turn the AVR 645 off using the Main Power
Switch A and check the speaker wiring or connec-
tions to external power amplifiers to make certain that
each speaker is connected to the correct output ter-
minal. When you have verified that all speakers are
