Shielded speaker cable? Definitely! Belden #8718 is a 12-AWG twisted pair with a foil shield and drain wire for an easy connection to earth ground. Connect the 12-AWG twisted pair to the appropriate amp and loudspeakers terminals. The drain wire should be connected to earth ground at one point only. I have it easy here in my listening room because my power amp chassis is connected to earth ground. Do not connect the drain wire to the speaker. If you don't have a readily available earth ground on your equipment, I suggest running the drain wire to the earth ground of your a.c. line. There are special a.c. socket plugs that have an earth ground connection only. If you are connecting the drain wire to earth ground, do not connect that drain wire to either wire of the twisted pair. Also, don't leave the drain wire unconnected as it can act as a very good receiving antenna. Shielding your speaker cables will greatly reduce static electricity that can form on cables when they rest on a carpeted floor, especially on cold, dry days. Shielded a.c. line cords can also help under strong interference conditions. |
