Balanced audio is the highest quality of analog audio distribution. Most professional audio components require signals that are transmitted over balanced connections using differential mode signaling to cancel out induced noise for crystal-clear audio. Differential mode signaling requires each wire to carry signals in opposite polarity to each other. Electromagnetic Interference (EMI) will induce an equal noise voltage in each wire and the amplifier measuring the difference in voltage between the two signals will reject the noise that is identical on both wires. Tributaries Balanced cables are sold in pair or mono.
