Getting to Know the Speakers
The two speakers are identical, so it doesn’t matter which one you use
on the left or right.
Using Close to a TV or Computer
TVs and computer monitors are magnetically sensitive devices and as
such are likely to suffer from discoloration or picture distortion when
conventional speakers are placed nearby. Note that discoloration can
also be caused by a magnet or demagnetizing tool that's too close to
your TV or monitor.
Removing the Grills Using the Cork Spacers
Connection the Speakers
࡮Before connecting the speakers, disconnect your amplifiers power
cord from the wall outlet and set its volume control to minimum.
࡮The speaker’s rated impedance is 4 . Make sure you connect an
amplifier that is compatible with a 4  impedance.
࡮Use the supplied speaker cables to connect the speakers to your
amplifier as shown.
1.Peel the
insulation off
the ends of
the speaker
cable and
twist the
core wires.
2.Loosen the
terminal screw
and insert the
speaker cable
into the hole
(until the core
wires are
inserted fully).
3.Fasten the
terminal
screw.
The type of speaker terminals used on the amplifier and their position
depends on the model. Refer to the amplifier’s instruction manual for
details on connecting speakers to the amplifier.
࡮Make sure the speaker’s positive (+) termi-
nals are connected to the amplifier’s positive
(+) terminals, and the speaker’s negative (–)
terminals are connected to the amplifier’s
negative (–) terminals.
࡮Make sure that the positive (+) and negative
(–) wires are not touching each other. If they
are, a short circuit may occur, damaging your
amplifier.
Care
To maintain the appearance of the speakers, you should periodically
wipe them with a soft, dry cloth. Do not use abrasive cloths, thinners,
alcohol, or other solvents that may damage the finish.
Before Using Your New Speakers
࡮
The speaker cabinets are made out of wood and are therefore
sensitive to extreme temperatures and humidity. Do not use
them in locations subject to direct sunlight or in humid
places, such as near an air conditioner, humidifier, bathroom,
or kitchen.
࡮Place the speakers on sturdy, flat surfaces. Putting them on
uneven or unstable surfaces where they may fall and cause
damage will affect the sound quality.
࡮Do not keep water or other liquids close to the speakers. If a
liquid is spilled over them, the woofer and tweeter inside may
be damaged.
࡮Do not handle the speakers with wet or damp hands.
Precautions
In catalogs and on packaging, the letter at the end of the product
name indicates the color. Specifications and operation are the same
regardless of the color.
The speakers can handle the specified input power when used for
normal music reproduction. If they’re fed any of the following sig-
nals, even if the input power is within the specified rating, exces-
sive current may flow in the speaker coils, causing burning or wire
breakage:
1. Interstation noise from an untuned FM radio.
2. Audio from a cassette that’s being fast-forwarded.
3. High-pitched sounds generated by an oscillator, electronic musi-
cal instrument, and so on.
4. Amplifier oscillation
5. Special test tones from audio test CDs and so on.
6. Thumps and clicks caused by connecting or disconnecting audio
cables (always turn off your amplifier before connecting or dis-
connecting cables).
7. Microphone feedback
The speakers contain powerful magnets. Do not put metal items,
such as screwdrivers, close to the speakers, as they damage to the
tweeter diaphragm.
