STS 150 Speaker System

Your Optimus STS 150 Speaker Sys-

tem has a 2-way acoustic suspension

design that utilizes an 8-inch specially

treated cone surrounded by rubber to

yield excellent low-end response and

tight, clean bass. A 1-inch mylar

tweeter diaphragm provides clear and

natural high-frequency sound repro-

duction.

The speaker cabinet is solid in con-

struction and is finished in woodgrain

vinyl. The decorative grille is acousti-

cally transparent.

Note: You need speaker wire (not

supplied) to connect your speaker.

SPEAKER PLACEMENT

Cautions:

• To prevent the cabinet from warp-

ing or discoloring, do not place the

speaker where it is exposed to

direct sunlight or excessive

humidity.

• Do not place the speaker where it

might be knocked over or hit by

falling objects.

Where and how you position each

STS-150 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.

If you place the speakers too far apart,

a sound “hole” could occur and you

might not get the proper stereo image

in the listening area. Compensate for

this by angling the speakers slightly in

toward the listening area.

If you place the speakers too close to-

gether, you could cancel out the ste-

reo 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 re-

sponse, place your speakers directly

on the floor and positioned against a

wall or in a corner.

To decrease the bass response, raise

your speakers off the floor or move

them away from the wall or corner.

Avoid placing your speakers on a sur-

face that absorbs sound, such as thick

carpeting. We recommend you experi-

ment 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.

Notes:

• Use 18-gauge speaker wire for

distances up to 25 feet. For

greater distance, use 16-gauge

wire. 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 con-

ductor’s insulation. Some 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 1/2inch of insulation from the

ends of each conductor, then twist

each end.

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 open-

ing, then release the tab.

6. Insert the other end of the marked

conductor into your receiver/

amplifier’s right positive terminal.

7. Connect the remaining conductor

to the receiver/amplifier’s right

negative terminal.

8. Repeat these steps for the left

speaker.

MAINTENANCE

Your Optimus STS 150 Speaker Sys-

tem is an example of superior design

and craftsmanship. The following sug-

gestions 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. Liq-

uids contain minerals that can cor-

rode electronic circuits.

• Keep the speaker away from dust

and dirt, which can cause prema-

ture wear of parts.

• Occasionally wipe the cabinet with

a cloth dampened with furniture

polish to keep it looking new. Do

not use harsh chemicals, cleaning

solvents, or strong detergents to

clean the speaker cabinet.

• Use and store the speaker in nor-

mal temperature environments.

Temperature extremes can

shorten the life of electronic cir-

cuits.

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.
