AM257817_00_V.pdf October 25, 2001 3 Setting Up Introduction Your 701® Direct/Reflecting® speakers re-create a natural balance of reflected and direct sound energy for a lifelike, spacious performance. As with all Bose® products, their design is meant to bring you high-quality concert-like sound. Figure 1 A natural balance of direct and reflected sound. Unpacking the speakers Carefully unpack the contents of the shipping carton. · Individually remove each speaker. · Retain the packaging material for possible future use. · If either speaker appears damaged, do not use it. Repack both speakers in the original carton and notify your authorized Bose dealer immediately. WARNING: To avoid danger of suffocation, keep the plastic bags that wrap these speakers out of the reach of children. WARNING: The left main speaker weighs 50 lb (22.7 kg) and the right accessory speaker weighs 45 lb (20.4 kg). Use good lifting practice to avoid injury. Figure 2 Package contents: · 1 left main speaker · 1 right accessory speaker · Owner's guide · Power cord · Bose interconnect cable · Two front speaker grilles · Two rear speaker grilles Front speaker grilles Rear speaker grilles Owner's guide Left main speaker Right accessory speaker Power cord Bose interconnect cable Attaching the speaker grilles Each speaker has both a front and a rear protective grille. The rear grille is the larger of the two. To attach these grilles to your speakers, line up the top curve of the grille so that it matches the curve of the speaker. Align the pins on the back of the grille to the mounting holes on the speaker cabinet and gently push the grille straight on. CAUTION: To prevent any damage to the speakers or electronics, be sure to keep the rear grilles on at all times. Do not place objects into any opening on the speaker cabinets. 4 October 25, 2001 AM257817_00_V.pdf Setting Up Placing the speakers The product label on the back of each speaker indicates LEFT or RIGHT. For best acoustic performance, place the left speaker on the left side as you face the front of your room and place the right speaker on the right side of your room. Keep the speakers 6 - 15 feet (1.8 - 6 m) apart and at least 12 inches (30 cm) from side walls (see Figure 3). It is important not to block the acoustic components at the rear of each speaker. To avoid this, place each speaker 10 inches (25 cm) from the wall behind it. Figure 3 Ideal speaker placement 12" minimum (30 cm) 10" minimum (25 cm) 6 - 15 ft (1.8 - 6 m) Note: Bose® 701® speakers are not intended to hang from walls, or to stand on shelves or tables. They are designed as floor-standing speakers only. WARNING: To prevent personal injury, do not place your speakers in high-traffic areas where they can be accidentally knocked over. Note: To prevent interference with your TV picture quality, place each speaker at least 2 feet (.6 m) from your TV screen. Figure 4 Place each speaker at least 2 feet (.6 m) from your TV screen. 2 ft. minimum .6 m 2 ft. minimum .6 m AM257817_00_V.pdf October 25, 2001 5 Setting Up Choosing the speaker cord It is important to use the proper gauge (thickness) of speaker cord. Standard zip cord (2-conductor, 18-gauge or .82 mm2 wire or larger) is recommended for most applications. You can find this wire at most electrical and hardware stores. If the length of speaker wire extends more than 30 feet (9 m) from a receiver or amplifier, refer to "Wire recommendations" on page 11 or contact your authorized Bose® dealer for more information. Note: If you require longer cable runs, or have speaker wire already installed in the wall, the Bose AC-7 adapter kit is available to accommodate this. The kit will also allow for the use of a larger gauge speaker wire. Refer to the enclosed list for correct phone numbers to order PN262061. Running the speaker cord through a wall or under a floor Make sure you have enough cord to reach from the receiver to the left main speaker. The Bose interconnect cable is not intended for in-wall installation. For in-wall installation, check your local building code requirements. Before proceeding, you may want to contact an electrical installer for information about your local building or safety regulations. Preparing the speaker cord Speaker cord consists of two insulated wires. The insulation around one wire is marked (striped, collared, ribbed, or may have writing on it). This marked wire is always positive (+). The plain wire is always negative (­). These wires correspond to the red (+) and black (­) terminals on the speaker, receiver, or amplifier. Note: It is sometimes difficult to distinguish wire markings. Inspect both wires carefully. To prepare the ends of the cord, strip approximately 3/8 to 1/2 inch (12 mm) of insulation from both wires. Then, twist the bare ends of each wire so there are no loose strands of wire. WARNING: Never use broken or frayed wiring, as damage or electrical shock may result. Making the connections Your 701® speaker system connects differently from conventional speaker systems. Both the LEFT and RIGHT outputs from your receiver or amplifier must connect to the left main 701 speaker. Please follow the connection instructions carefully to ensure proper performance. Figure 5 on page 7 indicates how the speakers are connected to the receiver. Connecting to the receiver Connect your speaker wire to the SPEAKERS A or MAIN (front) left and right speaker outputs on your amplifier or receiver. See your receiver owner's guide for any additional information or instructions. CAUTION: Before making any connections, turn off your receiver and unplug it from the AC power mains. Failure to do so may result in damage to your system. 6 October 25, 2001 AM257817_00_V.pdf Setting Up Making the connections (cont.) Figure 5 Wiring schematic L R er Output Input L R LFE/ Subwoofer L L R R 125/115C 225W Power Output Input LFE/ Subwoofer Receiver Left main speaker Press down the terminal tab on the bottom of the left main speaker to insert the appropriate wire (Figure 5). 1. Connect one cord to the left speaker output of your receiver or amplifier. A. Insert the marked wire at one end to the red (+) terminal. B. Insert the plain wire at that end to the black (­) terminal. 2. Connect the other end of the cord to the left (L) main speaker terminals (Figure 5). A. Insert the marked wire into the red (+) terminal. B. Insert the plain wire into the black (­) terminal. 3. Repeat steps 1 and 2 for the right (R) speaker connections. Note: The right speaker outputs are located on the left main speaker directly below the left speaker outputs. They are labeled with an R. Connecting the right accessory speaker to the left main speaker Use the supplied Bose® interconnect cable to make this connection. It is important to note the connector at each end is designed to be inserted in one orientation only. Match the curved top of the connector to the curved top of the jack on the rear connector cups. CAUTION: Never connect the right accessory speaker directly to a receiver output. Always connect the right accessory speaker to the left main speaker, then connect the left main speaker to the receiver.
