What is a Balanced Audio?

Balanced audio is a method of transmitting an audio signal using three conductors: a positive signal, a negative signal, and a ground. This design helps reduce noise and interference during transmission.

In a balanced connection, the positive and negative signals carry the same audio information but with opposite polarity. When the signal reaches the receiving device, the polarity is flipped and combined, which cancels out noise that may have been introduced along the cable.

Balanced audio connections are commonly used in professional audio equipment, recording studios, live sound systems, and broadcasting. They are typically carried through connectors such as XLR cables or TRS (tip-ring-sleeve) cables, allowing audio signals to travel longer distances with minimal noise or signal degradation.
