Balanced Line Cable Connector

Two signals wires plus a separate ground wire.

Balanced line cable connector.

The cable construction used for balanced telephone cables was twisted pair. Headphone cables come with a variety of connectors and it can be difficult for the uninitiated to differentiate between balanced and unbalanced. Trs connections have three contact points conductors separated by two insulator rings. For an unamplified telephone line a twisted pair cable could only manage a maximum distance of 30 km.

As you see in the diagram above there are three male pins inside the connector the groundwire the hot signal and the cold signal. On the other hand short cable runs carrying higher signal levels are less prone to audible noise. Open wires on the other hand with their lower capacitance had been used for. But what makes a balanced cable special is the way the gear utilizes that.

However this did not become widespread until repeater amplifiers became available. Trs cables can be used for mono balanced signals as well as stereo signals. A balanced cable by contrast has three conductors in the connector and three wires in the cable. Any noise picked up along the cable run will typically be common to both legs.

While they receive identical versions of the signal the polarity of the negative wire is inverted. An example of a mono balanced signal would be a line input or output from a mixer or audio interface. Balanced connections typically use shielded twisted pair cable and three conductor connectors. Headphones receive stereo signals over trs cables.

Balanced audio is a method of interconnecting audio equipment using balanced lines this type of connection is very important in sound recording and production because it allows the use of long cables while reducing susceptibility to external noise caused by electromagnetic interference. A ground a positive leg and a negative leg. For the purpose of this discussion we are focussing on the end of the cable that plugs into the source not into the headphones as the headphone cup connector does not determine unbalanced or. When you have a balanced cable both the positive and negative wires receive identical versions of a signal.

Balanced cable types xlr. Mic cables are a good example of such situations. Balanced xlr connectors have 3 pins. As the signal.

A balanced electrical signal runs along three wires. Balanced lines are ideal in situations involving lengthy cables and low signal levels where noise can be a problem. Trs connectors and cables. Xlr cables can send balanced audio signals up to 200 feet.

For a more technical explanation. Both legs carry the same signal but in opposite polarity to each other.
