Unbalanced Audio Cables

What is the difference between balanced and unbalanced audio cables?

Balanced audio cables have two conductors carrying the audio signal, with one carrying the signal in its original form and the other carrying an inverted version. This helps cancel out any interference picked up along the cable, resulting in a cleaner signal. On the other hand, unbalanced audio cables only have one conductor carrying the signal and a shield surrounding it. This makes them more susceptible to interference and noise, affecting the overall signal quality.
