Cat. No. 40-4084
PRO-LS2 Center-Channel Home Theater Speaker
Your Optimus PRO-LS2 Center-Chan-
nel Home Theater Speaker is designed
around a shielded 4-inch woofer and a
1/2-inch polycarbonate ferrofluid cooled
tweeter. The two-way speaker’s small
size makes it ideal for wall mounting
(using an optional 1/4-inch wall mount
speaker bracket) or placement on a
bookshelf (using the supplied speaker
stand). It can handle up to 75 watts
RMS for use in today’s high-power
home theater system.
The LS2 is designed for use with the
PRO-LS1 Mini Home Theater Satellite
Speaker (Cat. No. 40-4082/4083) as
part of a complete Home Theater
speaker system. The LS2 is timbre-
matched with the satellite speakers for
a seamless transition when sound
moves from speaker to speaker. (You
can also use the LS2 as a front or rear
satellite speaker.)
When the LS1s and the LS2 are used
with a subwoofer (such as Cat. No. 40-
4080 or 40-4081), the result is a dy-
namic sound experience, ranging from
42 Hz to 20 kHz.
Note: You need speaker wire (not sup-
plied) to connect your speaker (see
“Connecting the Speaker to an Amplifi-
er/Receiver” on Page 2).
SPEAKER PLACEMENT
Where and how you position speakers
has a great effect on the overall sound
of your surround sound system.
Cautions:
• Place speakers away from heat
sources such as radiators, stoves,
or other appliances.
• To prevent the cabinets from warp-
ing or discoloring, do not place
speakers where they are exposed
to direct sunlight or excessive
humidity.
• Do not place speakers where they
might be knocked over or exposed
to falling objects.

Center-Channel Speaker
The center channel output contains the
majority of the dialogue and sound that
comes from on-screen action. There-
fore, you should place the center-chan-
nel speaker as close as possible to the
television, either just above or below
the screen. Place the front edge of the
center-channel speaker grille flush with
the edge of the television.
Your center-channel speaker is mag-
netically shielded to prevent interfer-
ence with your television’s picture. It is
possible, however, that some interfer-
ence might occur.
If this happens, turn off your TV for 15
minutes and move the speaker back
about 1 inch from the front of the TV.
Turn on the TV and recheck. If interfer-
ence still occurs, move the center-
channel speaker back further until the
interference disappears.
ATTACHING THE
ANTI-SLIP PADS
Remove the adhesive backing and at-
tach the four supplied anti-slip pads to
the speaker stand as follows:
When installing the speaker above the
TV set,
place the thicker pads toward
the back of the speaker and the thinner
pads toward the front of the speaker.
When installing the speaker below the
TV set,
place the thinner pads toward
the back of the speaker and the thicker
pads toward the front of the speaker.
ATTACHING THE
SPEAKER STAND
1. Slide the metal bracket through
the bottom of the stand and use
the supplied Phillips head screws
to attach it to the stand.
2. Thread the supplied thumbscrew
through the slot in the bracket and
into the screw hole in the back of
the speaker. Do not tighten it.
3. Slide the speaker up or down the
bracket to the desired angle, then
tighten the thumbscrew securely.
CONNECTING THE
SPEAKER TO AN
AMPLIFIER/RECEIVER
Cautions:
• Do not exceed the speaker sys-
tem’s maximum power rating (see
“Specifications”).

• To avoid damage to the speaker
system or amplifier/ receiver, turn
off the amplifier/receiver before
making the connections.
Use 18-gauge speaker wire or lamp
cord for distances up to 50 feet. For
greater distances, 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. Color-coded wires
have a stripe running down one side of
the conductors. Marked wires have
ridges along one side of the conduc-
tors.
1. With the speaker in its approxi-
mate location, measure the dis-
tance to the amplifier and route the
wire from the speaker to the ampli-
fier.
2. Separate the wire conductors for a
length of about 2 inches, then
remove about 1/2inch of insulation
from the wire’s ends using a wire
stripper.
3. Press the speaker’s black nega-
tive (–) terminal tab and insert one
of the bare wire ends into the
opening. Then release the tab.
4. Press the speaker’s red positive
(+) terminal tab and insert the
other bare wire end into the open-
ing. Then release the tab.
5. Using the speaker wire’s coding as
a guide, connect the other end of
the speaker wire to the amplifier’s
center speaker terminals.
MAINTENANCE
To enjoy your Optimus PRO-LS2 Cen-
ter-Channel Home Theater Speaker for
a long time:
• Keep the speaker dry. If it gets
wet, wipe it dry immediately.
• Use and store the speaker only in
normal temperature environments.
• Handle the speaker gently and
carefully. Don’t drop it.
• Keep the speaker away from dust
and dirt.
• Clean the speaker’s cabinet with a
soft, dry cloth.
Caution: You might permanently
damage your speaker by cleaning
it with a vacuum cleaner. Instead,
use a feather duster or a soft cloth.
