Connecting the speakers
Each speaker connection on the amplifier comprises a
positive (+) and negative (–) terminal. Make sure to
match these up with the terminals on the speakers
themselves.
Caution
• 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 the speaker cable you’re going to use is
properly prepared with about 10 mm of insulator stripped
from each wire, and the exposed wire strands twisted
together (
fig. A).
To connect a terminal, unscrew the terminal a few turns
until there is enough space to insert the exposed wire
(
fig. B). Once the wire is in position, tighten the terminal
until the wire is firmly clamped ( fig. C).
Important
• 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.
• 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.
Placing the speakers
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.
• When placing speakers near the TV, we recommend
using magnetically shielded speakers to prevent
possible interference, such as discoloration of the
picture when the TV is switched on. If you do not have
magnetically shielded speakers and notice
discoloration of the TV picture, move the speakers
farther away from the 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
titled slight 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.
• To achieve the best possible surround sound, install
your speakers as shown below. Be sure all speakers
are installed securely to prevent accidents and
improve sound quality.
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.
