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.

Figure 4. This figure shows how to
connect bare wires to the terminals.
IMPORTANT: DO NOT REVERSE POLARITIES
(I.E., + TO – OR – TO +) WHEN MAKING CONNECTIONS.
DOING SO WILL CAUSE POOR IMAGING AND
DIMINISHED BASS RESPONSE.

BI-WIRING
ES30, ES80, ES90, ES100
The outer connection panel and internal dividing network of the ES30, ES80, ES90
and ES100 are designed so that separate sets of speaker cables can be attached
to the low-frequency transducer and midrange/high-frequency transducer por-
tions of this dividing network. This is called bi-wiring. Bi-wiring can provide several
sonic advantages and considerably more flexibility in power amplifier selection.

The speakers have coded termi-
nals 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.

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 ES 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.
