Use a shelf or one of the included wall brackets if the television does not provide a stable platform. Surround Channels For left and right surround channels, place one speaker on the left and another on the right, to the side of or slightly behind the listening area. Subwoofer Since the installation of a subwoofer can be somewhat more complicated than installing full-range speakers, it is essential that you read this section very carefully prior to connecting the subwoofer to your system. Should you have questions relating to installation, it is advisable to call either your dealer or JBL's Customer Service Department for advice. The performance of the subwoofer is directly related to its placement in the listening room and how the subwoofer is aligned with the satellite speakers. Setting the volume of the subwoofer in relation to the left and right speakers is also of critical importance because it's essential that the subwoofer integrate smoothly with the entire system. Setting the subwoofer's volume level too high will result in an overpowering, boomy bass. Setting the volume level too low will negate the benefits of the subwoofer. Here are several additional facts on installation that may prove useful. It is generally believed that low frequencies (below 125Hz) are nondirectional and, therefore, placement of a subwoofer within any listening room is not critical. Connect each + terminal on the back of the amplifier or receiver to the respective + (red) terminal on each speaker. Do not reverse polarities (i. e. , + to ­, or ­ to +) when making connections. Be certain that positive and negative wire strands are completely isolated to avoid short circuits that may damage your equipment. Center Channel Observe polarities when making speaker connections, as shown in Figure 5. Connect each + terminal on the back of the amplifier or receiver to the respective + (red) terminal on the speaker. Do not reverse polarities (i. e. , + to ­, or ­ to +) when making connections. Be certain that positive and negative wire strands are completely isolated to avoid short circuits that may damage your equipment. NOTE: On certain models using hexagonal terminal nuts, a small socket wrench is provided to help in properly tightening the terminals. Wiring diagram shows polarity connections for one channel of a home theater system. Figure 5. The satellites and center channel speaker feature terminals that can be connected in several different ways ­ e. g. , spade terminals and direct wiring (as shown here). 7 SUBWOOFER CONTROLS Rear Panel Subwoofer Connections If you have a Dolby® Digital or DTS® receiver/processor with a low-frequency-effects (LFE) or subwoofer output: RECEIVER/PROCESSOR ¡ SUBWOOFER OR LFE OUTPUT PHASE TM £ ¢ 15' (4. 5m) Subwoofer cable included § If your receiver/processor does not contain a Dolby Digital or DTS processor but has a subwoofer output: RECEIVER/PROCESSOR CS80SUB TSS-Sub800/230 FUSE T 2. 5A L 250V 120V­60Hz 200Watts 15' (4. 5m) Subwoofer cable included Subwoofer-Level Control Phase Switch LFE Input Line-Level Inputs Power Indicator LED Power Switch Important!

" Some Dolby Digital-equipped receivers/processors offer different setup options for each source or surround mode (e. g. , CD-stereo, videotape, Dolby, Pro Logic). In each case, follow your equipment's instructions to ensure that the subwoofer output is turned on and that the speakers are set to "Small" in each mode. [. . . ] Finding the exact location for optimum performance sometimes only involves moving the speakers up to a few inches in any direction. We urge you, therefore, to experiment with placement, if possible, until your speakers deliver their full potential. A Few Suggestions We recommend that you do not operate your speakers or subwoofer with the bass, treble and loudness controls set to full boost. This will place undue strain on your electronics and speakers, and could damage them. [. . . ]
