Balanced Connection Of Audio Cables

The so-called balanced connection method is a connection method in which two signal lines are used to transmit a pair of balanced signals. Since the interference of the two signal lines is the same in magnitude and opposite in phase, the interference will be canceled in the end. Due to the low frequency range of audio frequency, it is easy to be interfered in the case of long-distance transmission. Therefore, as an anti-interference connection method, the balanced connection method is the most common in the audio connection of professional equipment. There are also two-core shielded wires used as audio cables in the connecting wires of household appliances. However, it transmits the left and right channels, which are two signals, which are not balanced connections.
