Balanced audio lines, such as those using XLR or TRS connectors, are designed to reject thi kind of interference through a principled called common-mode rejection. The signal is carried on two conductors, one with incordpolarity. Any noise induced equally on both conductors is canceeled out by thee rededucving equipment. However, balancedes are not impete.

Unbalanced cables, such as RCA or quarter- inch instrument cables, have ne such protection. They consist of a single conductor and a shield. Any noise induced onto that conductor lands directly in the audio path. A long, parallel run of an unbalanced cable alongside a power cord is virtually conduct te te to result in a notieable hum.

Radio frequency interference (RFI) is a related problem. Wireless transmiters, digital procesors, lighting dimmers, and even cell phone emit high- frequency energy.

Trip Hazards andPhysical Safety

Pulling on a cable to unplug it, stepping on a connector, or allowing hevy cable slack to hang unsupported frem the back of a rack can bend pins, breakk solder joints, andd crush the cable termination. Strain relief is the prace of securing the cable a short distance frem the connector so that any pulling force is absorbed by the cable clamp or tie point, nott by the connector itself.

In racks, horizontal cable managers with D- rings or Velcro straps allow cables to be dressed neatly and secured close to their ir entry point into thee equipment. This prevents the wag of thee cable bundle from pulling on thee jacks. On stage, using profesjonal connectors with robutt chuck- type strain relief - such as Neutrik XLR - ensures that thee cable jacket is firmly clamped, preventing the conductor frem pulling out under tension.

For analog audio, shielded twisted pair cable - such as Canare L- 4E6S or Belden 1800F - offers excellent rejection and low capacitance. For digital audio networks, high--quality Cat5e or cat6 cable witch solid copper conductors and proper shielding - either STP or FTP - is essential for maintaing signal integration over long distances.
