Notes on speaker use
≥
Use only supplied speakers
Using other speakers can damage the unit, and sound quality will be
negatively affected.
≥
You can damage your speakers and shorten their useful life if you play
sound at high levels over extended periods.
≥
Reduce the volume in the following cases to avoid damage:
– When playing distorted sound.
– When the speakers are reverberating due to a record player, noise
from FM broadcasts, or continuous signals from an oscillator, test
disc, or electronic instrument.
– When adjusting the sound quality.
– When turning the unit on or off.
If irregular colouring occurs on your TV
The center speaker is designed to be used close to a TV, but the picture
may be affected with some TVs and setup combinations.
If this occurs, turn the TV off for about 30 minutes.
The demagnetising function of the TV should correct the problem. If it
persists, move the speakers further away from the TV.
Caution
Do not touch the front netted area of the speakers. Hold by the sides.
Turn off all equipment before connection and read the appropriate operating instructions.
Do not connect the AC mains lead until all other connections are completed.
Pay attention to the type of speaker and the connector colour when you
place the speakers.
Main unit (rear)
Connect to the terminals of the same colour.
Use of the speaker cable stickers is convenient when making cable
connections.
Speakers (rear)
Insert the wire fully, taking care not to insert beyond the wire insulation.

≥
Be careful not to cross (short circuit) or reverse the polarity of the
speaker wires as doing so may damage the speakers.
step 1
Positioning
How you set up your speakers can affect the bass and the sound field.
Note the following points:
≥
Place speakers on flat secure bases.
≥
Placing speakers too close to floors, walls, and corners can result in
excessive bass. Cover walls and windows with thick curtains.
≥
For optional wall mount, refer to page 17.
[Note]
Keep your speakers at least 10 mm away from the system for proper
ventilation.
Setup example
(Recommended:
5.1ch layout
)
Place the front, center, and surround speakers at approximately the same
distance from the seating position. The angles in the diagram are
approximate.
§
1
Position with at least 5 cm of space on all sides for proper ventilation.
§
2
Put on a rack or shelf. Vibration caused by the speaker can disrupt
the picture if it is placed directly on the TV.
§
3
Place to the right or left of the TV, on the floor or a sturdy shelf so that
it will not cause vibration. Leave about 30 cm from the TV.
Depending on the room layout, you may like to use only the front
speakers and subwoofer for space saving (
2.1ch layout
).

Do not attempt to attach these speakers to walls using
methods other than those described in this manual.
