Hi friends welcome to the new post. Here we will learn About XLR Pinout (3-Pin, 5-Pin & 7-Pin) Types and advantages. The XLR connector is an electrical connector that is used in different types of audio, video, and stage lighting instruments. As a circular design, these connectors come with three to seven pins. In this post, we will discuss XLR pinout, finding different types, and the advantages they have so let’s get started with Introduction to XLR Connectors
Introduction to XLR Connectors
XLR connectors were made by James Cannon who was the founder of Cannon Electric. So different connectors are called Cannon Plugs.
This plug is made by Cannon Electric as a Cannon X series. The module was configured with a latch to lock cables with each other and it was called Canon XL.
Finally model with a durable and rare rubber component covering the female XLR socket called the Cannon XLR connector.
The XLR stands for Cannon X-Series connector with Latch and Rubber.
XLR Pinout: The Basics
The XLR connectors are circular. The commonly used XLR is a 3-pin connector, with some other connectors from 2 to 7-pin configuring used. These types come with male and female versions.
The pin of the XLR connector is configured circularly.
3-Pin XLR Connectors
It has 3 pins and is mostly used in industry standards for balanced audio signals. XLR port comes with professional microphones. It is also used in electric wheelchairs and scooters.
| PIN | Description |
| 1 | Ground |
| 2 | Positive |
| 3 | Negative |
Common Applications of 3-Pin XLR Connectors
3-pin XLR connectors are used for interconnection powered speakers with line level signal used for the PA system. Recharable devices use this type of XLR connector. It has features to carry two to ten amps for 24 volts.
5-Pin XLR Connectors
XLR5 is used for DMX512 digital lighting control. It is also used for carrying dual-element audio signals such as stereo signals. The XLR connection comes with five pins like the XLR4 with the difference that it has an additional pin for power.
| Pin Number | Description |
| 1 | Audio+ |
| 2 | Audio- |
| 3 | Mic+ |
| 4 | Mic- |
| 5 | Power |
.
XLR6 Pinout
XLR6 comes with two types, the witchcraft type and the Neutrik type. Switchcraft is a symmetrical connector and the other is asymmetrical. The common use of XLR6 is a stage lighting control and professional stereo headsets with balanced microphones.
| Pin Number | Details |
| 1 | Data+ |
| 2 | Data- |
| 3 | Data+ |
| 4 | Data- |
| 5 | Ground |
| 6 | Power(+12V) |
7-Pin XLR Connectors
7-Pin XLR is used for connecting the valve-based condenser microphones and carries singlas also LT and HT voltage for valves. it also used for remote control of Le Maitre and Ultratec fog machines and for different special-purpose devices
XLR Female Pinout
It comes with a socket having 3 holes for accepting pins of male connections, this category used on mixers, amplifiers, and other instruments, working as input for audio signals.
The pinout for an XLR female connector is
- Pin 1: Ground
- Pin 2: Signal (+ve)
- Pin 3: Signal (-ve)
XLR3 Pinout
The XLR3 pinout is :
- Pin 1: Ground
- Pin 2: Signal (+)
- Pin 3: Signal (-)e.
XLR4 Pinout
The XLR connection having fur pins is used for intercom headsets. Among the four pins, two pins carry headphone signals and the other 2 pins carry microphone signals.
The other features are in DC power connections and cameras used in the film industry.
| Pin Number | Description |
| 1 | Left Channel + |
| 2 | Left Channel – |
| 3 | Right Channel + |
| 4 | Right Channel – |
Neutrik XLR6 pinout:
Neutrik XLR connectors are a common series of products made by Neutrik and comes with the professional audio industry a simple, striking, concept in connector.
- Pin 1: Ground
- Pin 2: Signal A (+)
- Pin 3: Signal A (-)
- Pin 4: Signal B (+)
- Pin 5: Signal B (-)
- Pin 6: Mic Ground
Switchcraft XLR6 pinout:
- Pin 1: Ground
- Pin 2: Signal A (+)
- Pin 3: Signal A (-)
- Pin 4: Signal B (+)
- Pin 5: Signal B (-)
- Pin 6: Center Pin
Hot Plugging
Hot plugging is the insertion and removal of components from the system when the system is working. In the XLR3 connector ground pin of the male and female make first contact when inserted. With that, it disconnects when removed.
It makes sure that no noise is produced in the system during connection creation. SO XLR connectors provdies good operation
Components of XLR Cables
Connector
The main component XLR cable is 3 pin connector. These connectors make use of metal to provide protection and durability from undesired noises and signal interference.
Shield
Over the internal wiring, XLR cables come with conductive material protection made with aluminum mesh or copper. This shield works as a fence for electromagnetic interference from external conditions. As a result shield ensures a quality signal.
Conductors
On the inner side of the XLR cable, there are 2 times inner conductors. One is a positive wire, and the other is a negative wire. These conductors are made of copper. But if there are quality and costly XLR cables, they come with conductors created with silver. Copper conductors are mostly used due to their low cost
Insulation
The insulation is used to separate conductors from one another to avoid signal interference and electrical connection. insulation materials are made with polyethylene, rubber, or PVC, based on dielectric properties.
Twisting
The main feature of XLR cable is the twisted of conductors. This twist reduces electromagnetic interference and crosstalk. The tight and compact twist, and better XLR cable work to reduce the interference.
Jacket
The most external XLR cable layer is the jacket. It is a flexible material like rubber. The main objective of a jacket is to protect internal components from environmental and physical effects. it can easily be identified since it has different colors
How do XLR connections work?
The positive audio single with ground signal plus negative signal is provided through XLR cable when two balanced devices are connected.
With inverted featues, these signals are the same as each other.
For electrical interference, noise enters both negative audio signals also positive audio signals. When both signals get balanced gadget at en on audio signals is inverted. However, these two signals are like to each other. The nose that was audio signals is inverted.
They cancel each other when real noise is mixed with inverted noise. In a result, only the original audio signal is left
The XLR pinout on A-series models (A15, A20, and A30) is
- Pin 1: Ground
- Pin 2: Signal (+)
- Pin 3: Signal (-)
Advantages of XLR Connectors
- They have features to provide 48 volts of phantom power that is needed to power the condenser microphone.
- Balanced wire cancels interference that is selected with the way.
- it has a small latch on connectors to save any unplugging.

FAQs
What do the pins mean in XLR?
- The standard 3-pin XLR connector used for microphones comes with numbered pins for a balanced connection. Pin1 is protection, pin 2 is hot and carries an in-phase signal, and pin 3 is cold and has an inverted signal
What is the use of 5-pin XLR?
The 5 Pin XLR is used for lighting control, especially for DMX512 standard. It is also used for stereo microphones and for different types of DC power supply.
What is the pin 1 on the XLR?
The supply voltage refers with a ground pin of connection, which is connected with a cable shield or ground wire in the cable or both
What is the voltage of the XLR pinout?
The common started for pin 1 to ground and pin 4 to 12 volt nominal, with pin 2 and 3 not used
Is XLR DC or AC?
XLR connectors used for DC power, genders opposed according to standard use for line level and mic level audio. Normally audio signal on XLR connectors follows the pin, like the male connector is the output and the female connector is the input.
How many ohms is XLR cable?
The impedance value is between 5 and 75 ohms. Common XLR configurations are 3-pin and 5-pin, and some 4-pin XLR cables come with some audio instruments such as intercoms.
Is XLR low or high impedance?
There is no specific difference in tone or feedback rejection between low and high. Low impedance systems is wired with XLR jacket plugs. it is commonly used in industry.
What is the maximum distance for XLR cable?
XLR – 100 feet (official); 1000 feet (theoretical)
Is XLR analog or digital?
XLR cable is commonly used for analog functions like microphones and interconnects.
Analog comes with low impedance needs so cables not be rated, but normally impedance is about 45 ohms
What are the two types of XLR?
XLR connectors come with male and female types for cable and chassis mounting configurations.
Why does XLR have 3 pins?
XLR connectors come with 3 pins for carrying balanced audio signals. This layout helps to reduce interference and noises, resulting in cleaner audio transmission for longer distances.
Why is XLR used?
It used for professional audio, video, and stage lighting equipment.
