When Cable Failure Is Not An Option

by | Audio, Production

Welcome back to Worship Production Talk! This month’s question comes from Gary in New Hartford, NY, who asks. ” How can I keep my XLR Cables from being damaged?” He adds, “Recently I lost signal to our single podium microphone, it was a new cable that already seemed damaged”. With all of the new audio technology available our entire service can go down or be interrupted by one bad cable. So it’s important to maintain your microphone cables and keep them in good working order to ensure clear audio quality and prevent disruptions during performances or recordings. Here are some best practices to keep your microphone cables in excellent condition.

Proper Handling and Storage

Avoid bending and kinking the cable, Never bend the cables sharply or create tight loops, as this can damage the internal wires. Make sure you coil the cable correctly correctly, Use the over-under coiling technique to prevent tangling and reduce stress on the cable. This method alternates the direction of each loop, helping the cable lie flat when uncoiled. Store the cables in a cool, dry place. Use cable ties or Velcro straps to keep them organized without over-tightening.

Regular Inspection

Always check the connectors to ensure that the XLR connectors (or other types) are clean and free of corrosion. Look for loose or damaged pins. Take a second to examine the cable jacket and inspect the entire length of the cable for cuts, nicks, or abrasions. Replace cables with significant damage to the outer jacket, then test for interference. Periodically test the cables for any signs of interference or signal loss, which can indicate internal damage.

Cleaning

It may sound funny, but cleaning cables of tape residue and dirt will make your job easier as well as make you look professional. Clean the connectors by using a dry, soft cloth to wipe the connectors. For more thorough cleaning, use contact cleaner designed for electronic connectors. Avoid getting liquids inside the connectors. Wipe down the cable jacket with a damp cloth if it becomes dirty. Ensure the cable is completely dry before use.

Preventing Damage During Use

Avoid stretching the cable from the connectors. Ensure the cable is long enough for your setup to prevent stretching or pulling, which can damage the internal wires. Avoid running cables through high-traffic areas where they can be stepped on or tripped over. Use cable covers or tape to secure them in place. When unplugging cables, pull from the connector, not the cable itself, to avoid stressing the connection points.

Repair and Replacement

For minor issues, such as a loose connector, you can perform basic repairs if you’re comfortable with soldering and have the necessary tools. For significant damage, or if you’re unsure about the repair, take the cable to a professional technician. Replace cables that show signs of significant wear or consistent performance issues. It’s better to invest in a new cable than risk audio problems during critical moments.

Use Quality Cables

High-quality cables are more durable and less prone to damage. While they may be more expensive upfront, they often last longer and provide better performance. Choose cables with good shielding to protect against interference and noise, especially in environments with a lot of electronic equipment.

Marking and Labeling

Use labels or color-coded bands to identify different cables, making it easier to manage and reduce the risk of accidental disconnections. If you’re working in shared spaces, mark your cables with your name or a unique identifier to prevent mix-ups.

Avoid Overuse

If you have multiple cables, rotate their use to distribute wear evenly and extend their lifespan. Use dedicated cables for specific purposes (e.g., one for studio use, another for live performances) to prevent overuse in any single environment.

You can extend the lifespan of your microphone cables, ensure consistent audio quality, and reduce the risk of unexpected failures during important events or recordings. The lifespan of a microphone cable is influenced by its quality, usage frequency, handling practices, and environmental factors. High-quality cables, when properly handled and maintained, can last over a decade, while lower-quality or heavily-used cables may need replacement within a few years. Regular inspection and maintenance are key to ensuring cables remain in good working order for as long as possible.
