If your cables are already installed, check to be sure they meet these standards. Consider the location of the speaker

20、s and be sure to allow enough cable to reach each one. This includes the extra length needed for wiring the speaker before inserting it into the ceiling. Preparing the cable wires Speaker cable consists of two insulated wires. The insulation around one wire is marked (striped, collared, or ribbed) t

21、o 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 1/2 in. (13 mm) of insulation from both wires. 2. Twist the bare end of each wire so loose strands will not touch across terminals

22、. Be sure to connect each wire to the proper speaker terminal, positive to positive (+) and negative to negative (). Note: For information on installing cable, consult a professional electrician or audio/video installer, or look for reference books at a local home building retail store. Placement gu

23、idelines Orienting and placing these identical speakers is critical to their performance. Follow these guidelines in choosing the approximate location for each speaker.

34、f your ability to complete this process, contact a professional installer. Certain forms of insulation (such as horse hair plaster, newspaper, cellulose, or any blown-in materials) may pose a risk of ignition. Be sure to keep all insulation away from speakers in accordance with the installation inst

35、ructions. WARNINGS: Make sure the spot chosen is safe for cutting. Do not cut through surfaces that may have hazards such as electrical wiring, conduits, or plumbing concealed behind them. Follow all other safety precautions. If you believe there is asbestos insulation in the ceiling where you want

36、to install a speaker, do not drill or cut there. Find a different ceiling area for the speakers instead. If there is another type of moveable insulation in the ceiling, you can proceed after reading these tips: You may need to cut or push the insulation away before inserting the speaker. Beware of h

37、idden nails when reaching into the ceiling to remove insulation. Wear gloves and protection for your mouth, nose, and eyes before handling insulation that contains fiberglass. Be sure keep a 4-6 in. (10-15 cm) area around the speaker hole free from any types of insulation to maximize acoustic perfor

38、mance. Using the template 1. Center the template on the spot where you want the center of the speaker grille. 2. Press the template to the ceiling with your hand or use painters tape to hold it in place. 3. Trace around the edge of the template. CAUTION: DO NOT trace around or cut around the tabs th

39、at are for use only when the template serves as a paint shield. Drilling a pilot hole 1. Choose the proper spade bit to drill a hole that is large enough for the blade of your cutting tool. WARNING: Use eye protection and be sure to observe all safety precautions while using a drill or cutting tool.

40、 2. Drill the hole inside the circle you have drawn. Choose a spot near the center or closer to the outside edge of the circle, depending on which will be easier when you begin to use your saw. Cutting the speaker hole Be sure to cut carefully to make the hole as regular as possible. However, when t

41、he speaker is in place, the frame overlaps the cutting edge by 5/8 in. (0.6 cm), which masks minor cutting inaccuracies. 1. Hold the cutting blade in a vertical position and keep it straight as you cut the hole. This helps prevent the blade from angling away from the outlined circle. 8 5/8 (21.9 cm)

Such material can interfere with a tight seal between the speaker and the ceiling. Getting the wire ready When your speaker cable is within reach of the

44、 hole you have cut, follow the procedure below: 1. Push any insulation away from inside the speaker hole. Be sure that all blown insulation is at least 4 to 6 in. (10 to 15 cm) from the edges of the hole. 2. Locate and pull out at least 14 in. (36 cm) of your speaker cable. Allow enough cable for wh

45、ere you stand to connect the wires. Connecting the speaker As you connect the wires, be careful to match the polarity of each wire to the proper terminal, as described below. An error here will adversely affect speaker performance. 1. Choose the one wire on the cable end that is marked with a colore

46、d collar or other indicator, which distinguishes it as the positive (+) wire. 2. Notice the red circle on the exposed end of the positive (+) speaker terminal. 3. Compress both ends of the terminal and fully insert the bared tip of the positive wire into the terminal opening. Avoid inserting any ins

47、ulated part of the wire. 4. Release pressure on the terminal to capture the wire. 5. Insert the other wire into the other terminal, marked with a black circle on the end to indicate it is negative (). CAUTION: Do not allow exposed wires to brush against each other. This could damage your speaker or
