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.

Speaker cable

• 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.

•To prevent damage to circuits, never short-circuit the positive (+) and negative (–) speaker wires.

•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).

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

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.
