The position of the subwoofer is not so critical because bass sound is not highly directional. For a sonorous sound field,
the use of two subwoofers is recommended, although you can obtain a good effect with one subwoofer. ( : subwoofer,
: front speaker)
■When using one subwoofer
Place the subwoofer on the outside of either the right or the
left front speaker.
y
If the subwoofer is placed directly facing the wall, the bass
sound may lessen because the sound from the subwoofer
and the sound reflected by the wall may cancel each other
out. To prevent this from happening, face the subwoofer
obliquely to the wall ( or ).
■ When using two subwoofers
Place the subwoofers on the outside of each front speaker.

Connect an amplifier (and front speakers) to this unit using commercially available speaker cables. Refer to the following
instructions to make connections.
■ Connecting to the speaker cable
1 Remove approximately 10 mm (3/8”) of
insulation from each of the speaker cables.
2 Twist the exposed wires of the cable
together to prevent short circuits.
3 Turn the knob counterclockwise to loosen.
4 Insert the bare wire into the hole in the side
of each terminal.
5 Turn the knob clockwise to tighten.
6 Test the firmness of the connection by
pulling gently on the cable at the terminal.
• Do not let the bare speaker wires touch each other,
because this could damage this unit or the amplifier,
or both of them.
• For connection, keep the speaker cables as short as
possible. Do not bundle or roll up the excess part of the
cables. If the connections are faulty, no sound will be
heard from this unit or the speakers, or both of them.
• Make sure that the + and – polarity markings of the
speaker terminals are observed and set correctly. If these
cables are reversed, the sound will be unnatural and lack
bass.
• Do not insert the insulation into the hole. The sound may
not be produced.
■ Banana plug connection
1 Tighten the knob.
2 Insert the banana plug connecter into the
end of the corresponding terminal.
