WIRING THE SYSTEM

IMPORTANT: MAKE SURE ALL EQUIPMENT IS

TURNED OFF BEFORE MAKING ANY CONNECTIONS

For speaker connections, use a high-quality speaker wire with polarity coding.

The side of the wire with a ridge or other coding is usually considered positive

polarity (i.e., +).

NOTE: If desired, consult your local JBL dealer about speaker wire and

connection options.

The speakers have coded

terminals that accept a variety

of wire connectors. The most

common connection is shown

in Figure 4.

To ensure proper polarity,

connect each + terminal on the

back of the amplifier or receiver

to the respective + (red)

terminal on each speaker, as

shown in Figure 5. Connect the

– (black) terminals in a similar

way. See the owner’s guides

that were included with your

amplifier, receiver and

television to confirm

connection procedures.

IMPORTANT: DO NOT REVERSE POLARITIES

(I.E., + TO – OR – TO +) WHEN MAKING

CONNECTIONS. DOING SO WILL CAUSE POOR

IMAGING AND DIMINISHED BASS RESPONSE.

of a stereo or home theater system.

BI-WIRING

LS40, LS60, LS80

The outer connection panel and internal dividing network of the LS40, LS60

and LS80 are designed so that separate sets of speaker cables can be

attached to the low-frequency transducer and midrange/high-frequency

transducer portions of this dividing network. This is called bi-wiring. Bi-wiring

can provide several sonic advantages and considerably more flexibility in

power amplifier selection.

FINAL ADJUSTMENTS

Check the speakers for playback, first by setting the system volume control

to a minimum level, and then by applying power to your audio system. Play

a favorite music or video segment and increase the system volume control

to a comfortable level.

NOTE: You should hear balanced audio reproduction across the entire

frequency spectrum. If not, check all wiring connections or consult the

authorized JBL dealer from whom you purchased the system for more help.

The amount of bass you hear and the stereo-image quality will be affected

by a number of different factors, including the room’s size and shape, the

construction materials used to build the room, the listener’s position relative

to the speakers, and the position of the speakers in the room.

Listen to a variety of music selections and note the bass level. If there is too

much bass, move the speakers away from nearby walls. Conversely, if you

place the speakers closer to the walls, there will be more bass output.

CARE OF YOUR SPEAKER SYSTEM

Each JBL LS Series enclosure has a finish that does not require any routine

maintenance. When needed, use a soft cloth to remove any fingerprints or

dust from the enclosure or grille.

NOTE: Do not use any cleaning products or polishes on the cabinet

or grille.
