! Place the surround speakers at 120º from the center. If you, (1) use the surround back speaker, and, (2) don’t
use the front height speakers / front wide speakers, we recommend placing the surround speaker right beside
you.
! If you intend to connect only one surround back speaker, place it directly behind you.
!
Place the left and right front height speakers at least one meter directly above the left and right front speakers.
THX speaker system setup
If you are using a THX certified subwoofer, use the
THX INPUT
jack on the subwoofer (if your subwoofer has one)
or switch the filter position to THX on your subwoofer.
See also THX Audio Setting on page 101 to make the settings that will give you the best sound experience when
using the Home THX modes ( page 60 ).
Some tips for improving sound quality
Where you put your speakers in the room has a big effect on the quality of the sound. The following guidelines
should help you to get the best sound from your system.
! The subwoofer can be placed on the floor. Ideally, the other speakers should be at about ear-level when you’re
listening to them. Putting the speakers on the floor (except the subwoofer), or mounting them very high on a
wall is not recommended.
!
For the best stereo effect, place the front speakers 2 m to 3 m apart, at equal distance from the TV.
! If you’re going to place speakers around your CRT TV, use shielded speakers or place the speakers at a suffi-
cient distance from your CRT TV.
! If you’re using a center speaker, place the front speakers at a wider angle. If not, place them at a narrower
angle.
! Place the center speaker above or below the TV so that the sound of the center channel is localized at the TV
screen. Also, make sure the center speaker does not cross the line formed by the leading edge of the front left
and right speakers.
! It is best to angle the speakers towards the listening position. The angle depends on the size of the room. Use
less of an angle for bigger rooms.
! Surround and surround back speakers should be positioned 60 cm to 90 cm higher than your ears and tilted
slightly downward. Make sure the speakers don’t face each other. For DVD-Audio, the speakers should be
more directly behind the listener than for home theater playback.
!
Try not to place the surround speakers farther away from the listening position than the front and center speak-
ers. Doing so can weaken the surround sound effect.
Connecting the speakers
Each speaker connection on the receiver comprises a positive (+) and negative (–) terminal. Make sure to match
these up with the terminals on the speakers themselves.
This unit supports speakers with a nominal impedance of 4
W
to 16
W
.
CAUTION
! These speaker terminals carry HAZARDOUS LIVE voltage. To prevent the risk of electric shock when con-
necting or disconnecting the speaker cables, disconnect the power cord before touching any uninsulated
parts.
! Make sure that all the bare speaker wire is twisted together and inserted fully into the speaker terminal. If any
of the bare speaker wire touches the back panel it may cause the power to cut off as a safety measure.
Bare wire connections
CAUTION
Make sure that all speakers are securely installed. This not only improves sound quality, but also reduces the risk
of damage or injury resulting from speakers being knocked over or falling in the event of external shocks such as
earthquakes.
1 Twist exposed wire strands together.
2 Loosen terminal and insert exposed wire.
3 Tighten terminal.

Notes
! Please refer to the manual that came with your speakers for details on how to connect the other end of the
speaker cables to your speakers.
! Use an RCA cable to connect the subwoofer. It is not possible to connect using speaker cables.
! If you have two subwoofers, the second subwoofer can be connected to the
SUBWOOFER 2
terminal.
Connecting two subwoofers increases the bass sound to achieve more powerful sound reproduction. In this
case, the same sound is output from the two subwoofers.
