• Keep the back of the speakers within 18 inches (45 cm) of the wall behind them. Figure 2 Placement guidelines 12" (30 cm) or more 18" (45 cm) or more LEFT speaker 4-12' (1-4 m) RIGHT speaker 18" (45 cm) or more CAUTION: For the most realistic sound image, make sure the left speaker is placed on the left and the right speaker is on the right side of your room, as you face them. AM264981_01 _V.pdf • August 13, 2002 Setting Up Setting Up Choose the cord It is important to use the proper gauge (thickness) of speaker cord. Wire recommendations Based on a maximum frequency response deviation of ± 0.5 dB Gauge Length 18 (0.82 mm2) 20 ft (6 m) 16 (1.3 mm2) 30 ft (9 m) 14 (2.1 mm2) 50 ft (15 m) Note: Before running the speaker cord through a wall or under a floor, check your local building code requirements and safety regulations. If necessary, contact an electrical installer for this information. Prepare the cord Speaker cord consists of two insulated wires. The insulation around one wire is marked (striped, collared, or ribbed). At the ends of each cord, strip approximately 1.2 inch (12 mm) of insulation from both wires. 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). Note: It is sometimes difficult to distinguish wire markings. Inspect both wires carefully. AM264981_01 _V.pdf • August 13, 2002 Setting Up Setting Up Make the connections Just press the terminal tab on the back of each speaker to insert the appropriate wire (Figure 3). CAUTION: Before making any connections, turn off your receiver and unplug it from the AC power (mains) outlet. Not doing so may result in damage to your system. CAUTION: Never use broken or frayed wiring, which can result in electrical shock or damage. 1. Connect one speaker cord to your right speaker. • Attach each marked wire (+) to the appropriate (+) terminal. • Attach each plain wire (–) to the appropriate (–) terminal. 2. Connect the other end of the same cord to the RIGHT SPEAKER OUTPUT of your receiver. • Attach each marked wire (+) to the appropriate (+) terminal. • Attach each plain wire (–) to the appropriate (–) terminal. 3. Connect the second cord to the left speaker and LEFT SPEAKER OUTPUT. Follow the steps in 1 and 2 above. Figure 3 Black How to make terminal con-Red Black nections + — + — +— Red Test the speakers 301® series V 201® series V To make sure your speakers operate correctly: 1. Turn on your receiver. Set the receiver to MONO (monophonic), if that is an option on your receiver. 2. Make sure that all special effects (such as surround sound) are turned off. 3. Set the balance control to normal (center position). 4. Play some deep bass passages of music through the speaker. The sound should seem to come from a point between the two speakers. The bass should be full and natural. If it is not, one of the connections may be reversed, causing the speakers to play out of phase (refer to “Make the connections” above). To correct the problem, make sure all the wires are connected positive to positive (+ to +) and negative to negative (– to –). Then repeat steps 1 through 4 above to re-test the speakers. AM264981_01 _V.pdf • August 13, 2002 Using and Maintaining Your Speakers Using and Maintaining Your Speakers Enjoying sound in a variety of ways Your 201® or 301® speakers are designed to work with a variety of stereo receivers and amplifiers as either front or rear channel speakers. The open, spacious performance of these speakers makes them an ideal choice for home theater, or for listening to CD’s, tapes, or radio broadcasts (Figure 4). Figure 4 301 and 201 series V speaker sound path 301® series V 201® series V Cleaning the speakers Clean the surface of your speakers with a soft damp cloth. Do not use any sprays near the system or allow liquids to spill into any openings. Also, do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives. The speaker grille panels require no special care. You may vacuum them carefully to remove dust. AM264981_01 _V.pdf • August 13, 2002 Reference Reference Troubleshooting Problem What to do No sound • Make sure the receiver is plugged in and turned on. • Check to be sure the AC power (mains) outlet is working. • Disconnect any headphones plugged into the headphone jack. • Make sure the receiver is not set to MUTE. • Refer to the owner’s guide that came with your receiver. • Check connections to both the speakers and the receiver. Refer to “Make the connections” on page 6. Correct any connection errors. No sound from one speaker • Disconnect the working speaker from the receiver. • Switch the cord of the “faulty” speaker from its original receiver jacks to the other set of jacks (the working speaker was originally attached to those jacks). – If the speaker now works, the problem is in your receiver. – If the speaker does not work, continue below. • Remove the c...
