PRO LX8 Bookshelf Speaker

Important: Be sure you remove the

protective packing materials before

using the speaker (see the separate

“Special Precautions” included with

your speaker).

Your PRO LX8 Bookshelf Speaker’s

internal elements were exclusively de-

signed to give you amazing music re-

production in a small enclosure. It

produces high sound quality with very

low distortion, and actually delivers

decreasing distortion as the sound

moves to the higher frequency ranges.

The 8-inch driver is specially designed

to accurately produce all sounds from

50 to 2,200 Hz.

The pliable diaphragm in the 2 × 4-

inch wide-dispersion tweeter can ac-

curately produce sounds from 2,200 to

25,000 Hz with extraordinarily low dis-

tortion. The tweeter’s unique design

means there is virtually no physical

limitation to its high-frequency sound

production.

The speaker cabinet is finished in

black woodgrain vinyl. The black cloth

grilles are acoustically transparent,

and you can remove them for safe and

easy cleaning.

The LX8’s features include:

Acoustic Desi

n — provides broad,

smooth frequency response.

360° Wide-Dispersion Tweeter —

reproduces frequencies over 20 kHz

and uses a pliable diaphragm to re-

duce or eliminate distortion caused by

excess vibration.

SPEAKER PLACEMENT

For the best stereo image, place a pair

of speakers on a bookshelf or table so

the distance between them is about

the same as the distance between the

listening area and the point halfway

between the speakers.

If you must place the speakers farther

apart, turn them slightly inward. If you

must place them closer to each other,

turn them slightly outward. You might

want to experiment with your speak-

ers’ placement to discover the best lo-

cation for them.

CONNECTIONS

With a pair of speakers placed in their

approximate locations, measure the

distance from each speaker to your re-

ceiver/amplifier. Use 18-gauge speaker

wire for distances of 50 feet or less.

Use heavier 16-gauge wire for distanc-

es greater than 50 feet.

For maximum bass response and the

best overall performance, connect

your speakers so they are in phase

with the receiver/amplifier terminals (+

to + and – to –). You can easily make

the proper connections with marked

speaker wire, available at your local

RadioShack store.

1. Separate the wire’s two conduc-

tors at both ends for a length of

about 2 inches.

2. Strip the insulation from the ends

of each conductor to expose 1/2

inch of metal wire, then twist the

loose wire strands.

3. Turn the left speaker’s negative (–)

terminal counterclockwise to

loosen it, and insert one of the

unmarked wire ends into the

opening. Then turn the terminal

clockwise to tighten it.

Note: You can also use banana

plugs to make this connection.

4. Turn the left speaker’s positive (+)

terminal counterclockwise to

loosen it, and insert the marked

conductor’s wire end into the

opening. Then turn the terminal

clockwise to tighten it.

5. Connect the opposite end of the

left speaker’s unmarked wire to the

receiver/amplifier’s left negative (–)

terminal.

Then connect the opposite end of

the left speaker’s marked wire to

the receiver/amplifier’s positive (+)

terminal

6. Repeat Steps 3–5 to connect the

right speaker.

MAINTENANCE

Your Optimus PRO LX8 Bookshelf

Speaker is an example of superior de-

sign and craftsmanship. The following

suggestions will help you care for your

speaker so you can enjoy it for years.

• Keep the speaker dry. If it gets

wet, wipe it dry immediately.

• Handle the speaker gently and

carefully.

• Use and store the speaker only in

normal temperature environ-

ments.

• Keep the speaker away from dust

and dirt, which can cause prema-

ture wear of parts.

• Wipe the speaker with a damp

cloth occasionally to keep it look-

ing new.

Caution: Do not clean the speaker

with a vacuum cleaner. This might

permanently damage it. Clean the

speaker with a feather duster or soft

cloth.

Modifying or tampering with the

speaker’s internal components can

cause a malfunction and might invali-

date the speaker’s warranty. If your

speaker is not performing as it should,

take it to your local RadioShack store

for assistance.
