Placement of Speakers

All stereo information is heard from the satellite speakers. The subwoofer contains no stereo information and the

sound is non-directional. As a result, the subwoofer does not necessarily have to be placed in any particular relationship to the satellites. Placing the subwoofer on the floor close to a wall or corner of a room, provides maximum bass efficiency. The subwoofer can be placed below tables, behind couches and on bookshelves, etc.

The satellite speakers are magnetically shielded and can be placed close the other computer monitor without distorting the video image. Best stereo effect is obtained

by placing speakers as far apart as the cord set allows.

Troubleshooting

When first installing a new system, some simple instructions may be overlooked which can cause the unit to be inoperative. Please make the following checks:

•Make sure all connecting plugs between the satellite speakers, subwoofer (if applicable) and computer are fully seated.

•Make sure the wall power outlet or power strip has power. The outlet can be checked with a lamp or some other appliance. If the power strip has a switch, make sure it is turned on.

•It is possible to test the unit by pulling out the audio cable that is connected to the computer and connecting it to an alternate audio source such as a portable CD player.

•When the unit is operative, vibrations may lead to the erroneous conclusion that the speakers are defective. In most instances, removing the vibrating object cures the problem.
