PRO CS-5 Center-Channel Speaker System

Your Optimus PRO CS-5 Center­Channel Speaker System is specially­designed for use as a center channel
speaker in your surround-sound audio/
video system, giving you wide-angle
sound and clear movie dialogue and
action. It is magnetically shielded, so
you can place it direct ly on top of your
television for the most efficient center­channel effect.

The speaker’s two 5-inch woo fers are
designed to produce the lower­frequency bass sounds (70 to 2.5
kHz), while the single 3

31/2-inch

¥

tweeter’s pliable diaphragm is de­signed to produce the hig h-frequency
treble sounds (2 to 25 kHz). The tweet­er’s unique design v irtually eliminates
all physical limitations to high-frequen­cy sound production.

While your PRO CS-5 can work with
most speaker systems, it is designed
to give the best results with Ra­dioShack PRO X77 (Cat. Nos. 40­2072 and 40-2077) or PRO LX5 (C at.
No. 40-4061) speakers.

SPEAKER PLACEMENT

Correct speaker positioning is vital for
the best performance. Since your PRO
CS-5 center-channel speaker is de­signed to reproduce the dialogue, its
best position is directly above or below
your TV’s screen.

The speaker’s acoustics have been
carefully designed to match the speak­er elements to the enclosure and its
damping materials. The result is an
amazingly smooth and broad frequen­cy response that allows the system to
accurately produce both bass and tr e­ble sounds with extraordinarily low dis­tortion.

: To avoid possible television pic-

Note

ture distortion, position the PR O CS-5
speaker above your TV so its front
edge is behind the TV’s front edge (the
speaker’s front is farther away from
you than the TV’s front).

CONNECTING TO YOUR
AMPLIFIER

For maximum bass respo nse and the
best overall performance, it is essential
that you keep your speakers in proper
phase (connected + to + and – to –).
We recommend you use color-coded
or marked wires to help you correctly
connect the speaker to your sound
system.

Note

: Color-coded wires have a stripe,
and marked wires have ridges running
down along one of the conductors.

Measure the distance from the speak ­er to the amplifier. For distances of 50
feet or less, use 18-gauge speaker
wire or ordinary lamp cord. For dis­tances greater than 50 feet, use heavi­er 16-gauge wire.

If your speaker wires ends have ba­nana plugs, simply insert them into the
terminal openings without loosening
the terminals.

If your speaker wire ends are plain
wire, follow these steps to connect the
speaker to your amplifier.

1. Separate the wire’s two conduc­tors about 1 inch at each end.

2. Remove about

1

/4 inch of insula-

tion from the ends of each wire.

3. Turn the speaker’s positive (+) ter­minal (with a red stripe) counter­clockwise to loosen it and insert
one end of the ridged or striped
wire into the opening. Then turn
the terminal clockwise to tighten it.

Note

: Y our local RadioShack store has
a wide selection of speaker wi re and
banana plugs.

4. Turn the speaker’s negative (–)
terminal (with a black stripe) coun­terclockwise to loosen it and insert
one end of the other wire into the
opening. Then turn the terminal
clockwise to tighten it.

5. Connect the other end of the
ridged or striped wire to the ampli­fier’s positive (+) output terminal.
