GENERAL CONNECTION INFORMATION

Separate and strip the ends of the speaker wire (not supplied) as shown. Speakers and electronics terminals have corresponding (+) and (–) terminals. Most manufacturers of speakers and electronics, including JBL, use red to denote the (+) terminal and black for the (–) terminal.

The (+) lead of the speaker wire is sometimes noted with

a stripe or other demarcation. It is important to connect both speakers identically: (+) on the speaker to (+) on the amplifier and (–) on the speaker to (–) on the amplifier. Wiring “out of phase” results in thin sound, weak bass and a poor stereo image.

With the advent of multi- channel surround sound systems, connecting all of

the speakers in your system with the correct polarity remains equally important in order to preserve the proper ambience and directionality of the program material.

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.

Figure 1

Both 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

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 1.

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 2. 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.

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 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.

Nearby reflecting surfaces can adversely affect stereo-imaging quality. If this happens, try angling the speakers slightly inward toward the listening position until the optimum effect is achieved.

CARE OF YOUR SPEAKER SYSTEM

Each Project Array enclosure has a finish that does not require any routine main- tenance. 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.
