Since the speakers are magnetically shielded, you can place them very close to the TV without worrying about the magnetic field distorting the picture. Center Channel For the center channel, place the speaker directly on top of, or below, your television. 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. The surround speakers should be mounted at a height of between 1. 5m (5 ft. ) and 2m (7 ft. ). 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. The side of the wire with a ridge or other coding is usually considered positive polarity (i. e. , +). Also, consult the owner's manuals that were included with your amplifier or receiver to confirm connection procedures. Satellites Observe polarities when making speaker connections, as shown in Figure 4. 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. [. . . ] Adjust the Subwoofer-Level Control until you obtain a pleasing blend of bass. Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range. Many users have a tendency to set the subwoofer volume too loud, adhering to the belief that a subwoofer is there to produce lots of bass. A subwoofer is there to enhance bass, extending the response of the entire system so the bass can be felt as well as heard. [. . . ]
