! 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 (3.3 ft.) directly above the
left and right front speakers.
Some tips for improving sound
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 (6 ft. to 9 ft.) 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 sufficient distance from your
! 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
! 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 (2 ft. to
3 ft.) 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 speakers. Doing so can weaken the
surround sound effect.
Connecting the speakers
Each speaker connection on the receiver com-
prises a positive (+) and negative (–) terminal.
Make sure to match these up with the terminals
on the speakers themselves.
! These speaker terminals carry HAZARDOUS
LIVE voltage. To prevent the risk of electric
shock when connecting 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
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
1 Twist exposed wire strands together.
2 Loosen terminal and insert exposed
3 Tighten terminal.

end of the speaker terminal.
