This configuration cancels out any noise or interference that may be induced on the line, resulting in a cleaner and more robust signal transmission.
Unbalanced Connections
Unbalanced connections use only two conductors: positive and ground. The positive conductor carries the audio signal, while the ground conductor provides a reference point. This type of connection is more susceptible to noise and interference, as there is no cancellation effect to eliminate unwanted signals.
Cable Types for XLR Wiring
XLR wiring requires specific cable types to ensure proper signal transmission and minimize interference. These cables vary in construction and characteristics, each suited for different applications.
The primary types of cables used in XLR wiring include:
Shielded Cables

- The shield prevents electromagnetic interference (EMI) and radio frequency interference (RFI) from affecting the signal.
- Ideal for applications where external noise and interference are present, such as live sound reinforcement and recording studios.
Twisted Pair Cables
- Consist of two insulated conductors twisted together.
- The twisting helps cancel out electromagnetic noise by creating a balanced signal.
- Commonly used for balanced audio connections, such as microphone and line-level signals.
Coaxial Cables
- Feature a single inner conductor surrounded by a conductive shield and an outer insulating jacket.
- Provide excellent shielding against EMI and RFI, making them suitable for high-frequency applications.
- Used for video signals, RF signals, and digital audio connections.
Troubleshooting XLR Wiring Issues
