REFERENCE Nederlands Italiano Français Deutsch English Accessories that can help For installation in a drop ceiling (where tile is installed below the ceiling joists), Bose offers an optional Drop Ceiling Kit for two speakers. It protects the tile from bearing the weight of the speakers. Instructions are included with the kit. For installation in new construction, Bose offers a Rough-in Kit for two speakers. It is designed for use after the studs are in place and before the wallboard is added to reserve a place for the speakers and indicate where the wallboard hole should be made. It also protects the wallboard by providing additional support for the dogleg clamps that secure the speaker to the wall. Instructions are included with the kit. For more information or to order an accessory, contact your Bose dealer. Or, to contact Bose directly, refer to the address list included in the carton. Using speaker cord Before you cut any cord, estimate how much will be needed by measuring the distance from the receiver/amplifier to where each speaker will be installed. Make some allowance if the cord must go around corners or through walls, and leave at least 14 in. (36 cm) of cord to pull from the wall for making the connections easily. Allow extra length if you are installing ceiling speakers, so that you can make connections while standing on the floor. Wire recommendations. Gauge Maximum Length 18 AWG (0.82 mm2) 20 ft (6 m) 16 AWG (1.3 mm2) 30 ft (9 m) 14 AWG (2.1 mm2) 50 ft (15 m) Preparing the speaker cord Speaker cord consists of two insulated wires. The insulation around one wire is marked (striped, collared, or ribbed) to identify it as positive. The other wire is negative. Note: It is sometimes difficult to distinguish wire markings. Inspect both wires carefully. 1. Strip approximately 1e2 inch (13 mm) of insulation from both wires. You will need a wire cutter and wire stripper for this work. 2. Twist the bare end of each wire so loose strands will not touch across terminals. Be sure to connect each wire to the proper terminal, positive to positive (+) and negative to negative (-). Before the wallboard goes up There are some standard guidelines for working in unfinished construction. • Begin this work after the studs and joists are in and the electrical wiring is completed. • Snap a chalk line across the face of the studs or the bottom of the joists and move backward as you drill, so you can keep the last hole drilled in your line of sight. 22
