English 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 18 (0.82 mm2) 16 (1.3 mm2) 14 (2.1 mm2) Length 20 ft (6 m) 30 ft (9 m) 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. 5
