Why Audio Cables Fail

Cables fail when in motion. That is to say cables that are pulled, yanked, moved, and twisted are bound to fail. 

Understanding how a cable fails helps you limit the conditions in which could cause it to fail again. 

Some of the reasons for failure include:

• - Stepping on it.
• - Dropping something heavy on it.
• - Roll something over it.
• - Corrosion.

Wire Damage:
• - Pulled wires such as tripping over wire.
• - Dropping something heavy on it.
• - Roll something over it.
• - Pulling on wires instead of connector when unplugging.
• - Internal wear and tear.
•  

What You Can Do: 

Never yank on connector ends if a cable is stuck. Follow the wire to the cause of the problem and fix the issue without putting undue strain on the wires and/or connectors.

 Make sure all connectors stay dry. If a cable end gets wet, immediately pull it from use and take it apart when you get a chance. Dry all parts and reassemble.

 Don't leave cables out when rolling around sound boxes or carts on a stage. When possible, move all cables out of the way so they are easily spotted so they aren't tripped over. Wide tape can be used to secure them to a floor to prevent tripping.

 Unplug cables by pulling straight out on the connector.

 Learn the proper way to wrap cables. In short, don't allow the cable to twist out of alignment and don't coil too tightly. A cable wrapped with a 1 foot diameter is as small as you should go. This prevents undue wear and tear. Wires are metal and have a natural bend. By maintaining this natural bend, you prolong the life of the cables. 

Buy a cable tester and check your cables on a regular basis. Also check them when you first buy them. Doing this, you ensure that all wiring is secure and the cable is good for the next time it is used.
