field presentations. The choices available are Hall
1, Hall 2, Theater, VMAx Near and VMAx Far. The
Hall and Theater modes are designed for multi-
channel installations, while the two VMAx modes
are optimized for use in delivering a full surround
field when only the front left and front right
speakers are installed. See pages 25 for a com-
plete explanation of the DSP surround modes.
Note that the Hall and Theater modes are not
available when a Dolby Digital or DTS soundtrack
is played.
On the 
STEREO
menu, the selection choices
made with the 
/
Buttons
E& on the
remote may either turn the surround processing
off for a traditional two-channel stereo presenta-
tion, or select 
5 C H Stereo
or 
7 C H
Stereo
depending on whether the 5.1 or
6.1/7.1 output is in use. The latter modes feed the
stereophonic input signal to both front speakers,
to the rear speakers and to both surround back
speakers (if in use), while the monophonic signal
parts are spread over all speakers, also the
Center. See page 28 for a complete explanation
of the 5 CH Stereo and 7 CH Stereo modes.
After the selections are made in the Dolby, DTS,
Logic 7, DSP (Surround) or Stereo menus, press
the 
/
¤
buttons 
D so that the cursor moves
to the 
BACK TO SURR SELECT
line and
presss the Set Button 
F.
After one input has been adjusted for analog or
digital input, speaker type and surround mode,
return to the 
INPUT SETUP
line on the
MASTER
menu and enter the settings for each
input that you will use. In most cases, only the
digital input and surround mode may be different
from one input to the next, while the speaker type
will usually be the same (inputs set to
GLOBAL
). But if prefered you can also select
different speaker types or turn speakers on or off
individually for each input in use.
Configuring the Surround Off
(Stereo) Modes
For superior reproduction of two-channel program
materials, the AVR offers two Stereo modes: an
analog Stereo-Direct mode that bypasses the digi-
tal signal processing circuitry for a completely
analog signal path that preserves the purity of the
original signal, and a digital mode that is capable
of providing bass management for optimal distri-
bution of the low frequencies between smaller
speakers and a subwoofer.
Stereo-Direct (Bypass) Mode
When the analog Stereo-Direct mode is selected
by pressing the Stereo Mode Selector
until 
SURROUND OFF
appears in the Main
Information Display
˜ and the Surround
Mode Indicator
( for Surround Off is lit, the
AVR will pass the analog source material directly
through to the front left and right speakers,
bypassing the digital processing circuitry.
In this mode, the front left and right speakers will
automatically be configured as 
LARGE
; it is not
possible to configure these speakers as 
SMALL
.
When the AVR is in the Stereo Bypass mode you
may still configure the subwoofer output so that
it is either turned off, with a full-range signal
going to the front left/right speakers, or you may
configure it so that the subwoofer feed is activat-
ed. The factory default setting is to have the sub-
woofer turned off for this mode, but you may
change that setting by following these steps:
1. Press the Speaker Button
6
'.
2. Press the Set Button
F@ to activate the
configuration menu.
3. Press the 
/
¤
Buttons
D on the remote or
the 
/
Buttons
7 on the front panel to select
the desired option.
SUB NONE
turns off the
feed to the subwoofer, while 
SUB <L+R>
turns it on.
4. When the desired setting has been entered,
press the Set Button
F@ to return to normal
operation.
Stereo-Digital Mode
When the Stereo-Direct (Bypass) mode is in use a
full range signal is always sent to the front
left/right speakers. By its nature, that option does
not pass the signal through the AVR’s digital sig-
nal processing, creating the requirement for full-
range speakers. If your front speakers are band-
width limited, “satellite”speakers, we recommend
that you do NOT use the Bypass mode, but rather
use the 
DSP SURROUND OFF
mode for
stereo listening.
To listen to programs in the two-channel stereo
mode while taking advantage of the bass man-
agement system, press the Stereo Mode
Selector
 until 
SURROUND OFF
appears in the Main Information Display
˜
and the DSP and 
SURR. OFF
Surround
Mode Indicators
( both light up. When only
the 
SURR. OFF
Surround Mode
Indicators
( is lit you are in the Stereo-Direct
(Bypass) mode.
When this mode is in use, the front left/right
speakers and subwoofer may be configured to
meet the requirements of your specific speakers
using the steps shown in the Speaker Setup sec-
tion on page 17.
Delay Settings 
Due the different distances between the listening
position for the front channel speakers and the
surround speakers, the amount of time it takes for
sound to reach your ears from the front or sur-
round speakers is different. You may compensate
for this difference through the use of the delay
settings to adjust the timing for the specific
speaker placement and acoustic conditions in
your listening room or home theater.
To re-synchronize the front, center and surround
channels at first measure and note the distance
from the listening/viewing position to the front,
center, surround and surround back (if any)
speakers in meters.
The Delay setting for all speakers configured for
your system will be available only (with 5.1 or
with 6.1/7.1 configuration) when any Dolby sur-
round mode is selected (except Dolby-3-Stereo).
In addition they are selectable with these modes
only, with all other modes the delay times are
fixed.
Note that the Delay settings are "Global" for all
inputs, using those Dolby modes, and need not to
be repeated with any input.
To start with the delay settings at first select any
input associated with such a Dolby mode. Next,
continue within the MASTER M E N U
(Figure 1). If the system is not already at that
point, press the OSD button

Night Mode Settings
The Night mode is a feature of Dolby Digital that
uses special processing to preserve the dynamic
range and full intelligibility of a movie sound track
while reducing the peak level. This prevents
abruptly loud transitions from disturbing others,
without reducing the sonic impact of a digital
source. Note that the Night mode is only available
when the Dolby Digital surround mode is selected.
To adjust the Night mode setting from the menu
press the OSD Button

Output Level Adjustment
Output level adjustment is a key part of the
configuration of any surround-sound product. It
is particularly important for a digital receiver
such as the AVR, as correct outputs ensure that
you hear sound tracks with the proper
directionality and intensity.
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 ambience, 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.
IMPORTANT NOTE: The output level can be
adjusted for each digital and analog surround
mode individually. This allows you to compensate
for level differences between speakers, that may
also vary with the surround mode selected, or to
increase or decrease the level of certain speakers
intentionally, depending on the surround mode
selected. Note that adjustments made for any
surround mode are effective with all inputs asso-
ciated with the same surround mode.
Before beginning the output level adjustment
process, make certain that all speaker connec-
tions have been properly made. The system
volume should be turned down at first. Finally,
make certain that the Balance Control
Ò is
set to the center “12 o’clock” position.
Using EzSet
Harman Kardon’s exclusive EzSet remote makes
it possible to quickly and accurately set the AVR’s
output levels without the use of a sound pres-
sure meter, although manual adjustment is also
available. However, for the easiest set-up, follow
these steps while seated in the listening position
that will be used most often:
1. Make certain that all speaker positions have
been properly configured for their “large” or
“small” settings (as outlined above) and turn
off the OSD system if it is in use.
2. Adjust the volume so that it is at - 1 5, as
shown in the on-screen display or Main
Information Display
˜.
3. Select any input associated with the surround
mode for which you want to adjust the output
levels. Remember that the same adjustments
must be made with all other surround modes
you´ve in use.
4. Hold the remote in front of you, being sure
not to cover the EzSet Sensor Microphone
Q at the top of the remote and aim it at the
AVR, don´t hold it vertically (like a micro-
phone).
5. Press and hold the SPL Indicator Select
Button
* for three seconds. Release it
when the Program/SPL Indicator
2 stops
flashing and remains lit. Press the 
5 Button
H on the remote if your system is
configured for 5.1 operation with standard
speakers or when it is configured for 7.1 oper-
ation but the surround back speakers are not
in use with the surround mode currently
selected. Press the 7 Button
H on the
remote only if your system is configured for
6.1/7.1 operation with a full speaker comple-
ment including rear surround speakers and the
surround back speakers are in use with the
surround mode selected. Note that all speak-
ers currently in use always are indicated by the
Speaker/Channel Indicators
$ in the
front panel display. Once the correct channel
SYSTEM CONFIGURATION  23
System Configuration
configuration button has been pressed the test
noise will be heard from the front left speaker.
6. At this point, EzSet will take over, adjusting
the output level of each channel so that when
the process is complete all levels will be equal
and at the set reference point. This process
may take a few minutes, depending on the
extent of adjustment required.
7. During the adjustment, you will see the loca-
tion of the channel position being adjusted
appear in the on-screen display (if connected)
and in the Main Information Display
˜,
alternating with a readout of the output set-
ting, relative to the reference volume level.
As the adjustment proceeds, a few things will
happen simultaneously:
• The channel position being adjusted will flash
in the Speaker/Channel Input Indicators
$. If the test noise is heard from a channel
other than the one shown in the Indicator, the
on-screen display or the front panel display,
there is an error in the speaker connections.
If this is the case, press the Test Button
8
TWICE to stop the adjustment. Then, turn the
unit off and verify that all speakers are con-
nected to the proper Outputs
.
Afterwards start the adjusting process again
from the beginning.
• As the individual channels are set, the channel
name and the adjustment offset will appear in
the on-screen display (if connected) and the
Main Information Display
˜. While the
level is changing, the Program/SPL Indicator
2 will change colors to reflect the output
level in relation to the reference.
A red indication shows that the level is too
high, while an orange 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 oper-
ating.
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 will return to normal
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.
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 31.
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 
CHANNEL ADJUST
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
ADJUST
line. If you are not at the main menu,
press the OSD Button
v to bring up the
MASTER MENU
(Figure 1), and then press
the 
¤
Button
D four times so that the
onscreen 
cursor is next to the 
CHANNEL
ADJUST
line. Press the Set Button
F to
bring the 
CHANNEL ADJUST
menu 
(Figure 8) to the screen.
Figure 8
Once the menu appears on your video screen,
first use the 
Button
D to move the on-
screen 
cursor so that it is next to the 
TEST
TONE
line. Press the 
/
Buttons
E& so
that 
O N
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
˜. If the sound
comes from a speaker location that does NOT
match the position indicated in the display, turn
the AVR off using the Main Power Switch 
1
and check the speaker wiring or connections to
external power amplifiers 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 
/
Buttons
E& 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 
/
¤
buttons 
D 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 
/
Buttons
E& on the remote
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 
) 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.

but-
tons 
D until the desired level is shown in the
display or on screen. Once the buttons are
released, the test noise will begin to circulate
again in five seconds.
When all channels have the same output level,
turn the Volume
) down to about –40dB,
otherwise the listening level may be too high as
soon as the source’s music starts to play.
Afterwards press the Test Tone Selector
8
button again to turn the test tone off and 
complete the process.
IMPORTANT NOTE: The Output level adjust-
ment made will be effective for all inputs, but
only for the actual surround mode selected. To
be effective for any other mode select that mode
(with any input) and repeat the level adjustment
described above. This will also allow you to com-
pensate level differences between speakers, that
may be different with each surround mode, or to
increase or decrease the level of certain speakers
intentionally, depending on the surround mode
selected.
Note: Output level adjustment is not available
for the VMAx or Surround Off mode, as no
surround speakers are used (so level differences
between the speakers in the room cannot
occur). But to compensate level differences
between stereo, VMAx and other surround
modes (independently from the input selected)
the outputs can be adjusted with the Level Trim
Adjustment procedure, see page 31, also for the
Surround Off (Stereo) and VMAx modes.
Once the settings outlined on the previous
pages have been made, the AVR is ready for
operation. While there are some additional
settings to be made, these are best done after
you have had an opportunity to listen to a
variety of sources and different kinds of program
material. These advanced settings are described
on pages 32 to 33 of this manual. In addition,
any of the settings made in the initial
configuration of the unit may be changed at any
time. As you add new or different sources or
speakers, or if you wish to change a setting to
better reflect your listening taste, simply follow
the instructions for changing the settings for
that parameter as shown in this section.
Note that any settings changed at any time, also
when the discrete buttons are used only, will be
stored in memory in the AVR, also if it´s turned
off completely, unless it will be reset (see page
42).
Having completed the setup and configuration
process for your AVR, you are about to 
experience the finest in music and home-
theater listening. Enjoy!
