Balanced Line Cable

Balanced xlr connectors have 3 pins.

Balanced line cable.

As you see in the diagram above there are three male pins inside the connector the groundwire the hot signal and the cold signal. The cable construction used for balanced telephone cables was twisted pair. Two signals wires plus a separate ground wire. However this did not become widespread until repeater amplifiers became available.

Two of those wires carry the signal while one carries the ground. Xlr cables can send balanced audio signals up to 200 feet. Any noise picked up along the cable run will typically be common to both legs. Open wires on the other hand with their lower capacitance had been used for.

One for the signal and one for the ground which makes them. Balanced cable types xlr. Unbalanced line level connections are usually implemented with rca jacks for audio while balanced line level connections typically utilize dual 3 pin xlr jacks for both the input and output. The longer the cable the more noise introduced.

Balanced connections typically use shielded twisted pair cable and three conductor connectors. Balanced cables have three wires inside the plastic casing. Unbalanced cables however only have two wires. Mic cables are a good example of such situations.

Balanced audio cables work best with balanced devices. For an unamplified telephone line a twisted pair cable could only manage a maximum distance of 30 km. In both cases one jack is normally used for each audio channel left and right. One of the signal wires gets inverted which allows the cable to completely avoid picking up outside interference.

Balanced lines are ideal in situations involving lengthy cables and low signal levels where noise can be a problem. Two signal wires and a ground wire. Balanced cables have three conductors and three wires. The difference in signal quality between balanced and unbalanced setups is especially pronounced in longer cable runs.

A ground a positive leg and a negative leg. Balanced audio technology is designed to reduce the effect of environmental noise on the quality of the signal. A balanced cable by contrast has three conductors in the connector and three wires in the cable. On the other hand short cable runs carrying higher signal levels are less prone to audible noise.

But what makes a balanced cable special is the way the gear utilizes that. As in the unbalanced cable the ground wire still surrounds the signal wires and is used as a shield against interference. A balanced electrical signal runs along three wires. Both legs carry the same signal but in opposite polarity to each other.
