How to Repair XLR Microphone Cables

XLR cables deliver quality sound to professionals in the television and audio production industries. Without proper care and repair, XLR cables that become damaged or worn can affect the quality of the sound for the particular production.

Difficulty: Moderate

Instructions

Things You'll Need:

• Screwdriver
• Solder (in wire form)
• Soldering iron
• Pliers

1. Determine which connector you need to repair. Unscrew the three screws on the outside of the connector to remove the outer case.

2. Identify which of the three wires is in need of repair. The three wires that you're looking at are the ground, red wire and blue wire. The two non-ground wires may be different colors depending on the brand of XLR you're repairing.

3. Use a soldering iron to solder the wire in need of repair to the proper pin. Reassemble the case and reattach the three screws on the outer case.

4. Test the cable to ensure that it's receiving good audio quality.

Tips & Warnings

• Apply the solder iron to the wire solder, not to the pin, when melting the solder. This ensures that the tip of the iron doesn't melt through the pin(s).
• Repeat Steps 1 and 2 if the audio is distorted.
• If you hear FM radio stations coming through the XLR, your ground wire may be damaged. Check the wire for any damage.
• The soldering iron will be hot so avoid contact with skin.
• Do not plug the soldering iron into an extension cord. Plug directly into the wall outlet.
