Where and how you position your
speaker has a great effect on the over­all sound of your system.

For the best stereo effect, position
each speaker an equal distance fro m
each other and the center of your lis­tening area.

If you must place speakers farther
apart than recommended, you can turn
them slightly toward each other to
achieve a more realistic effect.

For a slight increase in bass response,
place your speakers on a shelf or table
positioned against a wall or in a corner.

higher than that of the speaker, but
take care never to exceed the
speaker’s maximum power rating
(see “Specifications”).

• To avoid any damage to the
speaker or amplifier/receiver, turn
off the amplifier/receiver before
making connections.

Your local RadioShack store has a
wide selection of speaker wire. We rec­ommend you use color-coded or
marked wire to help you correctly con­nect the wire. Some color-coded wires
have a stripe running down one side of
the conductors. Some marked wires
have ridges alo ng on e s id e of the con­ductors.

With a pair of speakers in their approx­imate locations, measure th e distance
from each speaker to the amplifier. Use
18-gauge speaker wire or lamp cord for
distances up to 50 feet. For greater dis­tances, use 16-gauge wire.

1. Split apart about 4 inches of
speaker wire on each end.

Avoid placing your speak ers on a sur­face that absorbs sound, s uch as thick
carpeting.

Experiment to find the best setup for
your sound system.

CONNECTING TO AN
AMPLIFIER

Cautions:

• You can use an amplifier/receiver
with a power handling rating

2. Use a wire stripper to strip
of insulation from each wire end.
Twist the loose wire strands to pre­vent the wires from shorting.

CARE AND
MAINTENANCE

Your Optimus STS 800 8-I nch Three­Way Tower Speaker is an exam ple of
superior design and craftsmanship.
The following suggestions will help you
care for your speaker so you can enjoy
it for years.

• Handle the speaker gently and
carefully. Don’t drop it!

• Use and store the speaker only in
normal temperature environments.

• To maintain the speaker cabinet’s
finish, do not let it come in co ntact
with water vapor, alcohol, ben­zene, insecticide, or similar liquids.
Do not place a plastic covering on
top of the speaker, as the plastic’s
color could come off and stick to
the finish.

• Clean the speaker cabinet with a
soft, dry cloth.

damage your speaker by cleaning
it with a vacuum cleaner. Instead,
use a feather duster or a soft cloth.

excessive shocks. If they become
dented or bent, the sound distorts.

Modifying or tampering with the speak­er’s internal components can c ause a
malfunction and might invalidate your

not performing as it should, take it to
