on).
Press the Set button when the name of
the desired channel appears in the Main
Information Display and on-screen display,
and follow the instructions shown above to
adjust the level.
Repeat the procedure as needed until all chan-
nels requiring adjustment have been set. When
all adjustments have been made and no further
adjustments are made for five seconds, the
AVR 7500 will return to normal operation.
If you are using a disc with noise test signals or
an external signal generator as the source from
which to trim the output levels, you may use the
EzSet feature of the remote to guide you to the
correct SPL level. To use the remote for this pur-
pose, start the test tone from the source and
press and quickly release the SPL Indicator
Select to activate the sensor.
While the test tone is played, the Program/SPL
Indicator will change color to indicate the
level. When it is red, the level is too high; when it
is orange, the level is too low. To set the refer-
ence level, open the Volume Control
the SPL Indicator´s LED lights green when the
test signal is fed to the left front speaker. Then
adjust the level of all other speakers, while they
are receiving the test signal, until the LED lights
green for all channels. After the output levels for
all channels are aligned, press the SPL
Indicator Select to turn the sensor and
indicator off.
The channel output may also be adjusted using
the full-OSD on-screen menu system. First, set
the volume to a comfortable listening level using
the Volume Control . Then, press

will be turned off. This will allow you to use your
external test disc or other source material as the
test signal. Then, use the

Remember, when you are using a disc with test
signal (e.g. pink noise) or an external signal gen-
erator as the source, the goal is to have the out-
put level at each channel be equal when heard at
the listening position, with any surround mode
selected. When your test source is a normal disc
with music signals, you may adjust the level for
each channel and surround mode as you prefer,
e.g. you may lower the center channel level when
you find it to be too high or increase the level of
the rears when you find it to be too low with
specific surround modes.
If you wish to reset all the levels to their original
factory default of 0dB offset, press the
Buttons so that the on-screen cursor is

6-Channel/8-Channel Direct Input
The AVR 7500 is equipped for future expansion
through the use of optional, external adapters for
formats that the AVR 7500 may not be capable
of processing or to allow connection to the out-
put of high-resolution optical audio playback sys-
tems such as DVD-Audio or SACD. When a device
with six-channel outputs (5.1 audio) is used, con-

Note that when the 6-Channel or 8-Channel

when the 6-Channel or 8-Channel Direct Input is
in use and the tone or balance controls will not
