Balanced Xlr Cable Wiring
3 pin xlr audio pinout.
Balanced xlr cable wiring. The three wire system includes hot neutral and ground. The xlr connector is a type of electrical connector primarily found on professional audio video and stage lighting equipment. They give a lot of protection for the signals they carry and have the capacity to carry strong signals. 5 pin xlr wiring standard 5 pin xlr connectors are used primarily in lighting control applications as a dmx signal.
The following is the aes industry standard for balanced audio xlr wiring commonly known as pin 2 hot. When the audio source is fed into an xlr for example the negative signal wire inverts the phase of the audio signal. Positive negative and ground. A quarter inch trs cable is another balanced professional audio cable.
So immediately you have two identical audio signals traveling over the cables out of phase with one another. This produces an unbalanced audio cable. Current flows through the hot and. Modern 3 pin xlr cables are a form of balanced cable which means that they have three conductors.
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 genius of balanced cables works like this. How do balanced cables work and why they re awesome. They are most commonly associated with balanced audio interconnection including aes3 digital audio but are also used for lighting control low voltage power supplies and other applications.
Typically found in pro audio equipment they feature three wires rather than the two in an unbalanced rca interconnect. The dmx specification allows for two completely separate data channels over the one 5 pin connector but often you ll find the cable manufacturers cheap out and only provide a single channel. 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. The positive and shield of the xlr are joined together either at the xlr end or the rca end.
The easiest way is to solder a link between pins 1 and 3 shield and negative of the xlr rather than trying to solder the shield and negative wire to the sleeve contact of the rca. Balanced connections typically use shielded twisted pair cable and three conductor connectors. In most normal applications pin 1 is ground pin 2 is positive as documented in the aes14 1992 standard also commonly referred to as pin 2 hot and pin 3 is negative. Xlr cables can send balanced audio signals up to 200 feet.
The connectors are circular in design and have between three and seven pins. An xlr is a balanced cable used in a variety of fields for audio for scientific purposes. Balanced cable types xlr. Balanced xlr to rca cable balanced xlr interconnects are what many people consider to be a superior connection between components.
