Installation

Observe the following general precau- tions and read the safety instructions on pages 2 and 3 before using your SunÞre Subwoofer.

Never open the cabinet or remove the metal control panel as this might result in an electrical shock to you, or damage to the unit.

Protect it from prolonged exposure to direct sunlight and other direct sources of heat, such as heating vents and radiators.

To prevent Þre or shock, do not expose the unit to rain or moisture. If ßuid or a foreign object should enter the unit, immediately turn off the power and contact your SunÞre Dealer.

Avoid excessive exposure to extreme cold or dust.

Do not place heavy objects on top of the unit.

Do not place the subwoofer with its control panel against the ßoor.

If you wish to place your subwoofer so the drivers face the ßoor and ceiling, thereby moving up and down, use at least 1-1/2 inch high spikes or feet for support. They may be attached either with screws or self-stick backing. This arrange- ment will impart substantial house and ßoor shaking motion.

Four extra heavy, shock absorbing rubber mounting feet have been included. If your subwoofer tends to wander about slightly while in use, place these feet just inside the existing feet positions. These shock absorbing mounts will let the subwoofer rock freely, thereby absorbing low frequency rocking energy, allowing it to adhere solidly to the ßoor.

To move the subwoofer along the ßoor, rotate it onto one edge onto a plastic sheet or bag, and it will slide along easier.

Heat rise

Allow adequate ventilation around the metal control panel of the subwoofer.

Do not let anything come into contact with the panel and keep at least two inches away from any walls.

The metal control plate serves as the ampliÞer heat sink and also as a conduit to remove internal heat to the outside and into the atmosphere. It can reach temperatures of 60 degrees C, which will feel hot to the touch, using nerves of ßesh and blood as temperature sen- sors. As uncomfortable as it may feel, 60 degrees C cannot burn you, and in fact is almost cool to copper, silicon, steel, and aluminum, the materials from which your subwoofer is constructed.

AC Power Considerations

Ensure that the unit is plugged into an outlet capable of supplying the correct voltage speciÞed for your model.

Unplug your subwoofer’s power cord from the electrical outlet if it will be left unused for a long period of time.

Route the power-supply cord so it is not likely to be walked on or pinched by items placed upon or against it, especially at plugs, convenience receptacles, and the point where it exits from the unit.

Magnetic Fields

We recommend that you place your subwoofer further than two feet away from your TV, VCR, tape deck or com- puter, so the speaker’s magnet won’t distort the colors of your TV picture or erase your video tapes, audio tapes or computer discs.
