[. . . ] This symbol indicates that there are important operating and maintenance instructions in the literature accompanying this unit. This symbol indicates that dangerous voltage constituting a risk of electric shock is present within this unit. WARNING: To reduce the risk of fire or electrical shock, do not expose this apparatus to rain or moisture. UNPACKING The easiest way to remove the speaker from its carton is to turn the open side of the box down so that it is resting on a table or the floor, with the flaps spread out and away. [. . . ] Most pre-terminated speaker cables have color-coded connectors that make it easy to match output and inputs correctly. If yours do not, or if you are making your own out of paired, two-conductor wire, look for identifying marks on the insulation of the two conductors. Normally there will be printing, a stripe or a molded ridge along one of the conductors. Pull the two conductors apart for about an inch and strip approximately 1/4inch of insulation from the end of each. (A wire stripper will simplify this, but you can use an ordinary pocket knife to cut around and through the insulation down to the wire. ) Twist the strands of wire on each individual conductor tightly together. Loosen the nuts on a pair of binding posts until the holes through the metal posts are exposed, then insert the bare wire through the holes. Screw the nuts down finger-tight on the wire. Make sure that no strands of wire are touching from one binding post to the other or to any strands from the other conductor. Failure to observe this precaution at either end of the connection can result in amplifier malfunction or damage. Many pre-made speaker cables are terminated with metal pins. Loosen the nuts on a pair of binding posts until the holes through the metal posts are exposed, then insert the pins through the holes. Screw the nuts down finger-tight on the pins -- do not overtighten. Make sure that there is no metal-to-metal contact between the two pins or binding posts. Failure to observe this precaution at either end of the connection can result in amplifier malfunction or damage. Some speaker cables are terminated with U-shaped connectors called spade lugs. Loosen the nuts on a pair of binding posts and slip the spade lugs around the metal posts. Screw the nuts down finger-tight on the lugs and inspect to ensure they have remained firmly in place. Make sure that there is no metal-to-metal contact between the two lugs or binding posts. Failure to observe this precaution at either end of the connection can result in amplifier malfunction or damage. Bi-wiring - In bi-wiring, separate cables are connected from the amplifier or receiver output terminals to the speaker input terminals for the tweeter and woofers. ) This results in lower electrical resistance between the amplifier and speaker than singlewiring with the same gauge cable.
