STS 200 Speaker System

Your Optimus S TS 200 S peaker Sys ­tem has a 3-way acoustic suspension
design that utilizes a high compliant
10-inch woofer for excellent low-end
response characterized by tight, clean
bass. The specially treated 5-inch
midrange and
persion dome tweeter mesh seam­lessly to provide extremely clean vocal
and high frequency production.

The speaker cabinet is solid in
construction and is finished in
woodgrain vinyl. The decorative
grille is acoustically transparent.

Note:

You need speaker wire (not

supplied) to connect your speaker.

Where and how you position each
STS-200 speaker has a great effect
on the overall performance of your
sound system.

For the best sound and stereo effect,
place the speakers so the distance
between them is about the same as
the distance between the listening
area and a point halfway between the
speakers.

SPEAKER PLACEMENT

Cautions:

• To prevent the cabinet from warp­ing or discoloring, do not place the
speaker where it is exposed to
direct sunlight or excessive hu­midity.

• Do not place the sp eaker where it
might be knocked over or hit by
falling objects.

If you place the speakers too far apart,
a sound “hole” could occur and you
might not get t he proper st ereo ima ge
in the listening area. Compensate for
this by angling the speakers slightly in
toward the listening area.

If you place the speak ers too close t o­gether, you could cancel out the ste­reo image and the sound might seem
to be monaural. Compensate for this
by angling the speakers slightly away
from the listening area.

For the maximum increase in bass re­sponse, place your speakers directly
on the floor and positioned against a
wall or in a corner.

To decrease the bas s response, rai se
your speakers off the floor or move
them away from the wall or corner.

Avoid placing your speakers on a sur­face that absorbs sound, such as thick
carpeting. We recommend you experi­ment to find the best setup for your
sound system.

CONNECTIONS

Cautions:

• 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.

• We recommend you use color­coded or marked wire to help y ou
correctly connect the wire. Some
color-coded wires have a stripe
running down one side of th e con­ductor’s insulation. S ome marked
wires have ridges along one side
of the conductor’s insulation.

Follow these steps to connect each
speaker to your receiver/amplifier.

1. With the speakers placed in the
selected locations, route the
speaker wire from each speaker
to the receiver/amplifier.

2. Separate the conductors for a
length of about 2 inches on each
end.

3. Strip

1

/2 inch of ins ula tion fro m t he
ends of each conductor, then twist
each end.

Notes:

• Use 18-gauge speaker wire for
distances up to 25 feet. For
greater distance, use 16-gauge
wire. Your local RadioShack sto re
has a wide selection of speaker
wire.

4. Press the right speaker’s red
(positive) terminal tab and insert
the marked conductor into the
opening, then release the tab.

Note: Improper phasing can
decrease bass sounds. Be sure to
connect speaker terminals in
proper phase (+ to + and – to –).

5. Press the right speaker’s black
(negative) terminal tab and insert
the other conductor into the open­ing, then release the tab.

6. Insert the other end of the ma rked
conductor into your receiver/
amplifier’s right positive terminal.

7. Connect the remaining conduct or
to the receiver/amplifier’s right
negative terminal.

8. Repeat these steps for the left
speaker.

MAINTENANCE

Your Optimus STS 200 Speak er Sys­tem is an example of superior design
and craftsmanship. The following s ug­gestions will help you care for the
speaker so you can enjoy it for years.

• Keep the speaker dry. If it gets
wet, wipe it dry immediately. Liq­uids contain minerals that can cor­rode electronic circuits.

• Keep the speaker away from dust
and dirt, which can cause prema­ture wear of parts.

• Occasionally wipe the cabinet with
a cloth dampened with furniture
polish to keep it looking new. Do
not use harsh chemi cals, cleani ng
solvents, or strong detergents to
clean the speaker cabinet.

• Use and store the speaker in nor­mal temperature environments.
Temperature extremes can
shorten the life of electronic cir­cuits.

Caution: Do not clean the speaker
with a vacuum cleaner. This might
permanently damage it. Clean the
speaker grille with a feather duster or
soft cloth.
