D-325
The type of speaker terminals used on the receiver and
their position depends on the model. Refer to the
receiver’s instruction manual for details on connecting
speakers to the receiver.
Before Turning on Your Receiver:
• Make sure the speaker’s positive (+) terminals are
connected to the amplifier’s positive (+) terminals,
and the speaker’s negative (–) terminals are connected
to the amplifier’s negative (–) terminals. If you get the
polarity reversed, the sound will be unnatural, with a
limited bass range and poor stereo image.
• Make sure that the positive (+) and negative (–) wires
are not touching each other. If they are, a short circuit
may occur, damaging your amplifier.
The sound quality of the speakers is directly affected by
the size and shape of the room they’re used in and its
furnishings. When considering where to place your
speakers, read the following:
• Where possible, mount the speakers on speaker
stands, concrete blocks, bricks, or a sturdy bookshelf.
Putting them directly on the floor will emphasize bass
sounds, creating a boomy sound.
• If a speaker is placed on an uneven surface where it
can wobble or vibrate, bass performance will be
adversely affected. You can eliminate speaker wobble
by putting a shim made out of cork or metal, such as a
coin, underneath the speaker or stand, as shown.
• If you mount the speakers on a flat surface, such as a
bookshelf, you can improve the sound quality by
inserting cork spacers or coins in between the speaker
and the shelf. Raising them off the surface like this
will reduce the contact area and improve the sound.
• If you like lots of bass, mount the speakers on low
speaker stands and place them in front of a solid wall.
•Walls and furnishings affect sound quality. To achieve
a good stereo sound, put the left and right speakers in
similar locations at the same distance away from your
listening position and at the same height. If you put
them in totally different locations, for example, one
on the floor and the other on a bookshelf, the stereo
imaging will be adversely affected.
•To determine the best positions for your speakers,
imagine an equilateral triangle and put the left and
right speakers at the ends of the base. The ideal listen-
ing position is at or slightly behind the triangle’s apex.
Angle the speakers toward your listening position.
• Glass doors and smooth walls behind the listening
position can reflect the sound from the speakers and
can make sounds at certain frequencies louder. You
can prevent this by hanging sound-absorbing mate-
rial, such as thick curtain, on the door or wall.
To maintain the appearance of the speakers, you should
periodically wipe them with a soft, dry cloth. Stubborn
stains can be removed by using a soft cloth dampened
with water and a mild detergent. Dry the speakers
immediately afterward with a clean, dry cloth. Do not
use abrasive cloths, thinners, alcohol, or other chemical
solvents that may damage the finish.

of the speaker cable and twist
the core wires.
2. While pressing the lever, insert
the wire into the hole, and then
release the lever.
3. Make sure that the terminals are
gripping the bare wires, not the
insulation.
