To change the speaker cord
If you want to change the speaker cord, you can
detach the supplied speaker cord from the
connector.
1Press the connector onto a flat surface.
Make sure that the catcher is at the bottom.
2Pull the speaker cord from the
connector.
3Twist the stripped ends of the speaker
cord you want about 10 mm and insert
the speaker cord into the connector.
Make sure that the speaker cord is inserted
according to its polarity : + to + and – to –.
Otherwise the sound will be distorted and
will lack bass.
4Remove the connector from the flat
surface.
Notes•Connect the long speaker connecting cords to the
surround speaker terminals and the short speaker
connecting cords to the front and center speaker
terminals.
•To avoid the speaker cord from coming off the
speaker connector
– do not use a smaller-sized speaker cord. We
recommend that you use the AWG24 to AWG18
speaker cord size.
– use the same speaker cord size for all the speaker
connectors.
– twist the stripped ends of the speaker cords.
– insert the speaker cord securely to the back of the
speaker connector.
To avoid short-circuiting the
speakers
Short-circuiting of the speakers may damage
the receiver. To prevent this, make sure to take
the following precautions when connecting the
speakers.
Make sure the stripped ends of each
speaker cord does not touch another
speaker terminal, the stripped end of
another speaker cord, or the metal parts of
the speaker.
Examples of poor conditions of the
speaker cord
Stripped speaker cord is touching another
speaker terminal.
Stripped cords are touching each other
due to excessive removal of insulation.

Hooking Up and Setting Up the Speaker System
After connecting all the components,
speakers, and AC power cord, output
a test tone to check that all the
speakers are connected correctly.
For details on outputting a test tone,
see page 18.
If no sound is heard from a speaker while
outputting a test tone or a test tone is output
from a speaker other than the one whose name
is currently displayed on the receiver, the
speaker may be short-circuited. If this happens,
check the speaker connection again.
To avoid damaging your
speakers
Make sure that you turn down the volume
before you turn off the receiver. When you turn
on the receiver, the volume remains at the level
you turn off the receiver.
Performing initial setup
operations
Once you have hooked up the speakers and
turned on the power, clear the receiver’s
memory. Then specify the speaker parameters
(size, position, etc.) and perform any other
initial setup operations necessary for your
system.
TipTo check the audio output during settings (to set up
while outputting the sound), check the connection
(see page 19).
Clearing the receiver’s

setup
For the best possible surround sound, all
speakers should be the same distance from the
listening position (A).
However, the receiver lets you to place the
center speaker up to 1.5 meters closer (B) and
the surround speakers up to 4.5 meters closer
(C) to the listening position.
The front speakers can be placed from 1.0 to
7.0 meters from the listening position (A).
You can place the surround speakers either
behind you or to the side, depending on the
shape of your room (etc.).
However, we recommend that you place the
surround speakers behind you.
When placing surround speakers to your side
When placing surround speakers behind you
Note
Do not place the center speaker farther away from the

Specifying the speaker
parameters
1Press MAIN MENU repeatedly to select
the “SET UP”.
2Press V or v to select the parameter
you want to adjust.
3Press B or b to select the setting you
want.
The setting is entered automatically.
4Repeat steps 2 to 3 until you have set
all of the parameters that follow.
Initial settings
Parameter Initial setting
L R DIST. X.X m 3.0 m
C DIST. X.X m 3.0 m
SL SR DIST. X.X m 3.0 m
SL SR PL. XXXX LOW
xFront speaker distance
(
L R DIST. X.X m)
Set the distance from your listening position to
the front speakers (A on page 14).
xCenter speaker distance
(
C DIST. X.X m)
Set the distance from your listening position
to the center speaker. Center speaker distance
should be set from a distance equal to the front
speaker distance (A on page 14) to a distance
1.5 meters closer to your listening position
(B on page 14).
xSurround speaker distance
(
SL SR DIST. X.X m)
Set the distance from your listening position to
the surround speakers. Surround speaker
distance should be set from a distance equal to
the front speaker distance (A on page 14) to a
distance 4.5 meters closer to your listening
position (C on page 14).
TipThe receiver allows you to input the speaker position
in terms of distance. However, it is not possible to set
the center speaker further than the front speakers.
Also, the center speaker cannot be set more than
1.5 meters closer than the front speakers.
Likewise, the surround speakers can not be set further
away from the listening position than the front
speakers. And they can be no more than 4.5 meters
closer.
This is because incorrect speaker placement is not
conducive to enjoy surround sound.
Please note that, setting the speaker distance closer
than the actual location of the speakers will cause a
delay in the output of the sound from that speaker. In
other words, the speaker will sound like it is further
away.
For example, setting the center speaker distance
1–2 m closer than the actual speaker position will
create a fairly realistic sensation of being “inside” the
screen. If you cannot obtain a satisfactory surround
effect because the surround speakers are too close,
setting the surround speaker distance closer (shorter)
than the actual distance will create a larger sound
stage.
Adjusting these parameter while listening to the
sound often results in much better surround sound.
Give it a try!

Multi channel surround setup
(continued)TipThe surround speaker placement parameter is
designed specifically for implementation of the
Digital Cinema Sound modes with virtual elements.
With the Digital Cinema Sound modes, speaker
placement is not as critical as other modes. All modes
with virtual elements were designed under the
premise that the surround speaker would be located
behind the listening position, but presentation remains
fairly consistent even with the surround speakers
positioned at a rather wide angle. However, if the
speakers are pointing towards the listener from the
immediate left and right of the listening position, the
sound fields with virtual elements will not be as
effective.
Nevertheless, each listening environment has many
variables, like wall reflections.
Therefore, we recommend that you playback multi
channel surround encoded software and listen to the
effect each setting has on your listening environment.
Choose the setting that provides a good sense of
spaciousness and that best succeeds in forming a
cohesive space between the surround sound from the
surround speakers and the sound of the front
speakers. If you are not sure which sounds best, select
“PL. LOW” and then use the speaker distance
parameter and speaker level adjustments to obtain
proper balance.
Only when you use the speaker system
other than the supplied one, be sure to
set the following parameters.
For details on “NORM. SP.” (Normal Speaker), see
page 14.
xSub woofer selection (SW S.W. XXX)
•
If you connect a sub woofer, select “YES”.
•If you do not connect a sub woofer, select
“NO”. This activates the bass redirection
circuitry and outputs the LFE signals from other
speakers. xSurround speaker placement
(
SL SR PL. XXXX)*
This parameter lets you specify the height of
your surround speakers for proper
implementation of the Digital Cinema Sound
surround modes. Refer to the illustration below.
•Select “PL. LOW” if the location of your
surround speakers corresponds to section A.
•Select “PL. HIGH” if the location of your
surround speakers corresponds to section B.
* These parameters are not available when
“Surround speaker size SL SR ” is set to “NO”.

xFront speaker size (L R XXXXX)
•If you connect large speakers that will
effectively reproduce bass frequencies, select
“LARGE”. Normally select “LARGE”.
•If the sound is distorted, or you feel a lack of
surround effects when using multi channel
surround sound, select “SMALL” to activate
the bass redirection circuitry and output the
front channel bass frequencies from the sub
woofer.
•When the front speakers are set to “SMALL”,
the center and surround speakers are also
automatically set to “SMALL” (unless
previously set to “NO”).
•When the sub woofer is set to “NO”, the front
speakers are automatically set to “LARGE” and
you cannot change the setting.
xCenter speaker size (

•If you connect a large speaker that will
effectively reproduce bass frequencies, select
“LARGE”. Normally select “LARGE”.
However, if the front speakers are set to
“SMALL”, you cannot set the center speaker to
“LARGE”.
•If the sound is distorted, or you feel a lack of
surround effects when using multi channel
surround sound, select “SMALL” to activate
the bass redirection circuitry and output the
center channel bass frequencies from the front
speakers (if set to “LARGE”) or sub woofer.*

Tip*1–*3 correspond to the following Dolby Pro Logic
modes

*3 3 STEREO
TipInternally, the LARGE and SMALL settings for each
speaker determine whether or not the internal sound
processor will cut the bass signal from that channel.
When the bass is cut from a channel, the bass
redirection circuitry sends the corresponding bass
frequencies to the sub woofer or other “LARGE”
speakers.
However, since bass sounds have a certain amount of
directionality, it best not to cut them, if possible.
Therefore, even when using small speakers, you can
set them to “LARGE” if you want to output the bass
frequencies from that speaker. On the other hand, if
you are using a large speaker, but prefer not to have
bass frequencies output from that speaker, set it to
“SMALL”.
If the overall sound level is lower than you prefer, set
all speakers to “LARGE”. If there is not enough bass,
you can use the BASS parameter in the TONE menu
to boost the bass levels. To adjust the bass, see page
25.

Enjoying Surround Sound
You can take advantage of surround sound
simply by selecting one of the receiver’s pre-
programmed sound fields. They bring the
exciting and powerful sound of movie theaters
and concert halls into your home. You can also
customize the sound fields to obtain the sound
you want by changing the surround parameter.
To fully enjoy surround sound, you must
register the number and location of your
speakers. See “Multi channel surround setup”
starting from page 14 to set the speaker
parameters before enjoying surround sound.
