Connecting Speakers

Connecting the Speakers

• Connect the right channel speaker to the R speaker connector on the CD receiver, and the left channel speaker to the
L speaker connector.
• Connect the "+" connector on each speaker to the "+" connectors on the CD receiver, and connect the "–" connector
on each speaker to the "–" connectors on the CD receiver. Use the red wires of the speaker cables to connect the "+"
connectors.

• To prevent damage to circuits, never short-circuit the
positive (+) and negative (–) speaker wires.
Placement
The sound quality a speaker system reproduces varies
greatly depending on room construction and area of the
room in which it is installed, as well as the location and
size of the furniture. For better-quality sound, observe
the following precautions.
• Placing the speaker system directly on the floor can
result in undesirable boom, that is, sound with
extremely heavy bass. Place each speaker on a speaker
stand, concrete blocks, bricks or a rigid bookshelf.
• High-quality bass sound cannot be obtained if the
speakers are not seated on a stable speaker stand or
other base.
• To obtain a deeper bass sound, mount the speakers on
lower speaker stands and place them in front of a wall
of sufficient rigidity.
• In many rooms, the furniture and walls affect the
reproduced sound quality. For stereo sound reproduc-
tion, placing the right and left speakers in the same
relative position produces the best results. If they are

wire.
• Be sure to connect speakers that have an impedance of
4 ohms to 16 ohms. Connecting a speaker with an
impedance lower than 4 ohms may damage the
speaker.
• Do not connect the speaker cord to the L and R connec-
tors at the same time (i.e., 1). Do not connect more than
two speaker connectors to the same speaker (i.e., 2).
i.e., 1
placed in extremely different positions, the right- and
left- channel balance will be adversely affected.
• The ideal placement of the speaker system is as fol-
lows: Imagine an equilateral triangle and position the
right and left speakers on both ends of the base. The
ideal listening position is at or slightly to the rear of
the triangle apex.
• Glazed doors or surrounding walls in front of the
speaker system may resonate specific frequency
ranges due to reflected sound. To eliminate this reso-
nance, place some sound-absorbing material, such as
a thick curtain, in front of the doors or walls.
Tips:
• The speaker cabinet is made of wood and is therefore
sensitive to extreme temperatures and humidity. Avoid
placing the speakers in locations subject to direct sun-
light, or in smoky or humid places.
• Place the unit on a rigid, level surface.
