Balanced audio is a method of transmitting audio signals that reduces noise and interference. It uses three wires: one for the positive signal, one for the negative signal, and a ground wire. This configuration helps cancel out any unwanted noise that may be picked up along the way, making it ideal for professional audio equipment and long cable runs. In balanced audio systems, connectors like XLR or TRS are commonly used. These connectors ensure a secure connection and maintain the integrity of the audio signal. Balanced audio is often preferred in settings such as recording studios and live sound environments for its superior sound quality.
