If parallel can't be avoided, leave as much space as possible between audio and power cables. A single perpendicular crossing of power and audio cables is much better than a parallel run. The best technique to reduce unbalanced cable noise is to be careful with cable placement. How do you reduce noise when using unbalanced cables? Older, non-LED stage lighting (such as spotlights or dimmers) can also add signal interference. Noise can come from a variety of electrical and radio interferences, but it most commonly comes from power cables, which can create a humming sound if they're near cables carrying unbalanced audio. This minimizes the risk of unwanted noise. However, the ground wire itself also acts like an antenna, picking up unwanted noise along the way.īecause unbalanced cables can pick up noise as a signal is sent along the cable, they’re best used for short distances, like connecting a guitar to a nearby amp. The ground wire acts as a reference point for the signal. The signal wire, as the name suggests, carries the audio signal to where it needs to go.
What Is Unbalanced Audio?Īn audio cable carrying an unbalanced signal uses two wires: a signal and a ground. To understand that, let's dive deeper into how balanced and unbalanced audio works. This susceptibility (or lack thereof) to interference is due to how the cable is made. The ground wire in an unbalanced audio cable can pick up unwanted noise as the audio signal travels through it. Unbalanced audio, on the other hand, is susceptible to picking up noise and interference over longer distances. In general, balanced audio will give you a better, stronger audio signal without any extraneous noises. One of the major differences between these cables is that balanced audio has less risk for unwanted noise, while unbalanced audio can pick up humming or buzzing sounds in certain environments.
