• As the individual channels are set,
the channel name and the adjust-
ment offset will appear in the on-
screen display (if connected) and
the Main Information Display
˜. While the level is changing,
the Program/SPL Indicator c
will change colors to reflect the
output level in relation to the refer-
ence. A red indication shows that
the level is too high, while an
amber indication shows that the
level is too low. When the indicator
is green, the level is correct, and
the test noise will move to the next
channel.
• While adjustments are being made,
the red LED under the AVR
Selector f will flash. This is
normal, and indicates that EzSet
is operating.
7. After the test noise has circulated
once through each channel, it will
send the tone to each channel once
again, to verify the settings.
8. After two complete circulations of
the tone, the levels are set. The
Program/SPL Indicator c will
remain green at each channel. Upon
completion of the second circulation,
the Program/SPL Indicator c
will flash green twice and then go
out. The tone will stop and the
AVR580 will return to normal
operation.
If you find that the output levels chosen
by EzSet are either uncomfortably low
or high, you may repeat the procedure.
Return to Step 2 and adjust the master
volume either slightly higher or lower to
accommodate your particular room layout
and your tastes. You may repeat this pro-
cedure as many times as necessary to
achieve a desired result. In order to pre-
vent possible damage to your hearing or
your equipment, we emphasize that you
should avoid setting the master volume
above 0dB.
If the levels of the surround back speak-
ers in your 6.1- or 7.1-channel system
seem very high in comparison to the
other channels, it may be due to your
pointing the remote away from these
speakers during the level-setting process,
as the microphone sensor is located on
the front of the remote (opposite the
position of the surround back speakers
situated behind you). This may be corrected
by using the manual output level adjust-
28
ment process described below. While
checking the level of each speaker,
point the remote toward the ceiling and
check the level as indicated by the SPL
Indicator c c . Point the remote toward
the AVR in order to transmit the com-
mands to raise or lower the level for a
particular channel. Point the remote
toward the ceiling again to check
whether the SPL Indicator c c reflects
a correct level, or further adjustment is
necessary.
NOTE: The subwoofer output is not
adjusted when the test tone is in use.
To adjust the subwoofer output, you
must use an external source, following
the instructions on page 36.
Manual Output Level Adjustment
Output levels may also be adjusted man-
ually, 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 CHANNEL
ADJUST menu (Figure 8). If you are
already at the MASTER MENU, press
Button n until the on-screen
the ¤
cursor is next to the CHANNEL
ADJUST line. If you are not at the
MASTER MENU, press the OSD
Button v to bring up the MASTER
MENU (Figure 1), and then press the
Button n until the on-screen
is next to the CHANNEL ADJUST
line. Press the Set Button p to bring
the CHANNEL ADJUST menu
(Figure 8) to the screen.
When the CHANNEL ADJUST
Button n
menu appears, press the ¤
until the on-screen › cursor is next to the
TEST TONE line. Press the
Buttons o
37 so that ON is high-
lighted and the AVR's internal test tone
will begin to circulate from speaker to
speaker in a clockwise direction into all
speakers. The test noise will play for two
seconds in each speaker before circulat-
ing, and a blinking on-screen cursor will
appear next to the name of each speaker
location when the sound is at that speaker.
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 ˜. If the sound
from a speaker location does NOT match
the position indicated in the display, turn
the AVR580 off using the Main Power
Switch 1 and check the speaker wiring
or connections to external power ampli-
fiers to make certain that each speaker is
connected to the correct 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
o
on the remote to bring all speak-
37
ers to the same volume level. When one

Continue to adjust the individual chan-

same from each speaker. Adjustments
should be made with the

main volume controls. If you are using

for precise level adjustment, set the

You may also adjust the output levels

the sensor and indicator, simply press and
release the SPL Selector Button
