Manual Output Level Adjustment - Harman Kardon AVR 7500 Owner's Manual

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 will remain green at each
channel. Upon completion of the second circu-
lation, the Program/SPL Indicator
flash green twice and then go out. The tone
will stop and the AVR 7500 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
menu (Figure 8). If you are already at the main
menu, press the Button until the on-
screen cursor is next to the
line. If you are not at the main
menu, press the OSD Button
the (Figure 1), and then
press the Button four times so that the
on-screen cursor is next to the
line. Press the Set Button
bring the

Once the menu appears on your video screen,
first use the Button
screen cursor so that it is next to the TEST
TONE line. Press the / Buttons
so that ON is highlighted.
You will hear a test noise circulate from speaker
to speaker in a clockwise direction around the
will 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
comes from a speaker location that does NOT
match the position indicated in the display, turn
the AVR 7500 off using the Main Power
Switch 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

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

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
to buttons on the remote.

while using the level indication feature of the
