JBL CS480 Placement, Left and Right Front Channels, Center Channel, Surround Channels, Subwoofer

PLACEMENT

Left and Right Front Channels

For left and right front channels, place one satellite to the left and another to the right of the television, as shown in Figure 1. 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 5 ft. (1.5m) and 7 ft. (2m).

Subwoofer

Since the installation of a subwoofer can be somewhat more compli- cated 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 advis- able 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 use- ful. It is generally believed that low frequencies (below 125Hz) are nondirectional and, therefore, placement of a subwoofer within any listening room is not critical. While in theory it is true that the larger wavelengths of extremely low frequencies are basically nondirec- tional, the fact is that, when installing a subwoofer within the limited confines of a room, reflections, standing waves and absorptions gen- erated within the room will strongly influence the performance of any subwoofer system. As a result, specific location of the subwoofer becomes important, and we strongly recommend that you experiment with placement before choosing a final location. Placement will depend upon your room (for example, whether or not your room permits placement of the subwoofer near either satellite) and the amount and quality of bass required.
