SYSTEM CONFIGURATION 27
System Configuration
8.After the test noise has circulated once
through each channel, it will send the tone to
each channel once again, to verify the settings.
9.After two complete circulations of the tone,
the levels are set.The Program/SPL
Indicator
2
will remain green at each
channel. Upon completion of the second circu-
lation, the Program/SPL Indicator
2
will
flash green twice and then go out.The tone
will stop and the AVR 4500 will return to nor-
mal operation.
If you find that the output levels chosen by EzSet
are either much lower or much higher than the
"0dB" reference setting or even at the limits of
the +/-10dB variation range for the output levels,
depending on the sensitivity of the speakers in
use and your specific room layout, you may
repeat the procedure. Return to Step 2 and
adjust the master volume either higher or lower
appropriately to the output levels set previously
(e.g. when levels were set to about "+7dB"
reduce the master volume for 7dB), to accommo-
date your particular room layout and your speak-
ers.You may repeat this procedure as many times
as necessary to achieve a desired result. In order
to prevent possible damage to your hearing or
your equipment, we emphasize that you should
avoid setting the master volume above 0dB.
Manual Output Level Adjustment
Output levels may also be adjusted manually,
either to set them to a specific level with an SPL
meter,or to make fine tuning adjustments to the
levels obtained using the EzSet remote.
Manual output level adjustment is most easily
done through the CHANNELADJUST
menu (Figure 8). If you are already at the main
menu, press the
¤
Button
D
until the on-
screen
›
cursor is next to the CHANNEL
ADJUSTline. If you are not at the main
menu, press the OSD Button v to bring up
the MASTERMENU(Figure1), and then
press the

four times so that the
on-screen
›
cursor is next to the CHANNEL
ADJUSTline. Press the Set Button
F
to
bring the CHANNELADJUSTmenu
(Figure 8) to the screen.

Once the menu appears on your video screen,
first use the

so that ON is highlighted.
You will hear a test noise circulate from speaker
to speaker in a clockwise direction around the
room.The test noise will play for two seconds in
each speaker before circulating, and a blinking
on-screen cursor will appear next to the name of
each speaker location when the sound is at that
speaker. Now turn up the volume until you can
hear the noise clearly.
IMPORTANT NOTE: Because this test noise will
have a much lower level than normal music, the
volume must be lowered after the adjustment for
all channels is made, but BEFORE you return to
the main menu and the test tone turns off.
NOTE: Remember 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
Y
. If the sound
comes from a speaker location that does NOT
match the position indicated in the display, turn
the AVR 4500 off using the Main Power
Switch
1
and check the speaker wiring or con-
nections to external power amplifiers to make
certain that each speaker is connected to the cor-
rect output terminal.
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
‹

Buttons
EZ
on the remote to bring all
speakers to the same volume level.When one of
the
‹
/
›
buttons is pushed, the test noise circula-
tion 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.The on-screen cursor
›
and the
test noise can also be moved directly to the
speaker to be adjusted by pressing the

on the remote.
Continue to adjust the individual channels until
the volume level sounds the same from each
speaker. Note that adjustments should be made
with the

only, NOT the main volume controls.
If you are using a sound-pressure level (SPL)
meter for precise level adjustment with the test
tone, open the main Volume Control
c
to -
15dB and set the individual output level for each
channel so that the meter reads 75dB,
C-Weighted Slow.After all settings are made turn
the main volume down.
You may also adjust the output levels manually
while using the level indication feature of the
EzSet remote.To activate the sensor and indica-
tor,simply press and release the SPL Indicator
Select Button
d
on the remote while the test
tone is circulating and set the main Volume
Control
c
to -15dB (respectively higher or
lower, if needed, as outlined above).The
Program/SPL Indicator
2
will change color
to indicate the level.Adjust the level using the
‹

Buttons
5
on the frontpanel until the LED
lights green for all channels.When it is red, the
level is too high; when it is orange, the level is
too low. Press the SPL Indicator Select
d
button when you are finished to turn the sensor
and Indicator off.
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 35.
