Balanced Microphone Cables

• Balanced microphone cables are constructed with three wires, often enclosed within a tube of wire mesh that provides a degree of shielding from outside interference. One of the three wires is the ground connection between the microphone and the amplifier or mixing board, the while the other two carry the audio signal, split into two parts. Any interference encountered along the way will create a similar degree of line noise on each wire. When the cable reaches its destination, the two feeds are recombined, at which point the audio signal is made whole again, but each line's noise cancels the other out.
