ANALOG AUDIO CABLE - BALANCED

A balanced analog cable is a type of cable designed to transmit analog audio signals with high resistance to noise and electromagnetic interference. It is the standard in professional audio applications, as it maintains signal quality even over long distances.

How does it work?

A balanced cable uses three conductors per channel:

1. Positive signal (+)

2. Negative signal (–): an inverted copy of the positive signal

3. Ground

The two signal conductors (positive and negative) carry the same information but in opposite phases. When the signal reaches the receiving equipment, the negative signal is inverted and added to the positive. Any noise picked up along the way (which affects both lines equally) is automatically cancelled through a process known as common-mode rejection.
