WIRING THE SYSTEMIMPORTANT: MAKE SURE ALL EQUIPMENT ISTURNED 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 positivepolarity (i.e., +).NOTE: If desired, consult your local JBL dealer about speaker wire andconnection options.The speakers have coded termi-nals that accept a variety of wireconnectors. The most commonconnection is shown in Figure 4.To ensure proper polarity, connecteach + terminal on the back ofthe amplifier or receiver to therespective + (red) terminal oneach speaker, as shown in Figure5. Connect the – (black) terminalsin a similar way. See the owner’sguides that were included withyour amplifier, receiver andtelevision to confirm connectionprocedures.IMPORTANT: DO NOT REVERSE POLARITIES(I.E., + TO – OR – TO +) WHEN MAKING CONNECTIONS.DOING SO WILL CAUSE POOR IMAGING ANDDIMINISHED BASS RESPONSE.STANDARD CONNECTIONFigure 5. Wiring diagram shows polarity connections for one channelof a stereo or home theater system.BI-WIRINGThe outer connection panel and internal dividing network of the TS models aredesigned so that separate sets of speaker cables can be attached to the low-fre-quency transducer and midrange/high-frequency transducer portions of this divid-ing network. This is called bi-wiring. Bi-wiring can provide several sonic advan-tages and considerably more flexibility in power amplifier selection.Figure 6.SINGLE-STEREO AMPLIFIERFigure 7.DUAL-STEREO AMPLIFIERFigure 8.FINAL ADJUSTMENTSCheck the speakers for playback, first by setting the system volume controlto a minimum level, and then by applying power to your audio system. Playa favorite music or video segment and increase the system volume controlto a comfortable level.NOTE: You should hear balanced audio reproduction across the entirefrequency spectrum. If not, check all wiring connections or consult theauthorized JBL dealer from whom you purchased the system for more help.The amount of bass you hear and the stereo-image quality will be affectedby a number of different factors, including the room’s size and shape, theconstruction materials used to build the room, the listener’s position relativeto 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 toomuch bass, move the speakers away from nearby walls. Conversely, if youplace the speakers closer to the walls, there will be more bass output.CARE OF YOUR SPEAKER SYSTEMEach JBL TS Series enclosure has a finish that does not require any routinemaintenance. When needed, use a soft cloth to remove any fingerprints ordust from the enclosure or grille.NOTE: Do not use any cleaning products or polishes on the cabinetor grille.StandardConnectionSpeaker Wire3Figure 4.
