A two-conductor line in which both conductors have the same impedance with respect to ground. Since noise pickup is equal on both conductors, common-mode interference is cancelled at the load.
Refers to a cable design that uses the same wire types for the signal and ground. Twisted pair cable is a balanced line
A method of carrying sound signals which reduces interference by using a third conductor, the shield. The two inner conductors carry the same sound signal, one is positive and the other is negative. Any interference induced into the cable is equal and opposite in each of the inner conductors and is cancelled out. It is important to use balanced lines when carrying low level signals (e.g. microphones) along long cable runs. See unbalanced line.

A circuit in which neither side of the line is grounded. This minimizes crosstalk or noise pickup between pairs in the same cable.
A pair of ungrounded conductors whose voltages are opposite in polarity but equal in magnitude. Balanced lines reduce interference from external sources like radio frequencies and light dimmers since they are typically shielded by a third conductor surrounding them.
Also known as a Double-Ended Transmission Line or Cable. A cable having two identical signal conductors, one on which resides a signal and on the other its complement (in polarity), both balanced in absolute voltage difference, referenced to ground, as equal and constant, independent of voltage polarity, which yields a mutual coupling of the electromagnetic fields between the signals. Twin-ax (coax with a signal pair of conductors) is an example of a balanced line.
A pair of ungrounded conductors ('hot' and 'cold') whose voltages are opposite in phase but equal in magnitude. At the destination end, the phase of the 'cold' is reversed thereby doubling the signal strength and cacelling any induced noise. Balanced lines therefore reduce interference from external sources like radio frequencies and light dimmers.
Cable having two identical conductors with the same electrical characteristics that provide common and differential mode symmetry to ground.
Line with two identical signal conductors that are 180 degrees out of phase with each other, and one ground. This type of line is very resistant to line noise.
an audio line comprising three conductors: two carrying signal and a ground (shield) wire, in which one of the signal wires carries the sound, while the other carries an inverted copy. When the signal reaches the destination, the inverted copy is flipped and added to the original. Any noise that has been induced into the signal is also inverted. When this is combined with the "un-inverted" noise, it cancels it out. Thus, balanced lines are less susceptible to hum and can carry audio signals over longer distances. Balanced audio lines typically use 3-pin XLR or 1/4-inch tip-ring-sleeve phone connectors.
A cable having two conductors which carry voltages opposite in polarity and equal in magnitude with respect to ground.
A data communications line where two wires are present, the signal and its opposite (or complement), the actual signal being the difference between the two voltages on these wires. Balanced lines have excellent noise and interference rejection properties.
A cable having two identical conductors with the same electromagnetic characteristics in relation to other conductors and to ground.
A transmission line consisting of two conductors in the presence of ground, capable of being operated in such a way that when the voltages of the two conductors at all transverse planes are equal in magnitude and opposite in polarity with respect to ground, the currents in the two conductors are equal in magnitude and opposite in direction.
In telecommunications (or professional audio), a balanced line or balanced signal pair is a transmission line consisting of two conductors in the presence of ground, which relies on balanced impedances to minimize interference. The signals on each line are typically the inverse of one another.
