XLR Definition and History
Before we look into the particulars of this type of microphone cable, let’s first learn about why it is called an XLR.
Today, the letter XLR stands for External Line Return and has been available for more than half a century.
However, when it was conceptualized, these letters were defined differently.
The XLR connector was pioneered by James H. Cannon, the founder of Cannon Electric.
With its origins, it’s common for some elders to call it a cannon plug or a cannon connector, although these names became obsolete later on.
Cannon X, XL, and XLR
It was initially marketed as the Cannon X Series, but the succeeding version is called the Cannon XL.
The L came from the latch that binds the wires together in place, which many competitors adapted the same design.
Cannon further improved their cable by modifying the female socket.
The company embedded it with a synthetic rubber polychloroprene to further improve quality and durability.
This version is called the XLR, which stands for Cannon X Series cable with latch and rubber.
A revision of the XLR is made by a company called Neutrik.
Their XLR cable did not use a small screw, a standard component in the pin assembly of Cannon XLRs.
It is considered a design flaw because these screws are prone to falling out, making the pins twisted after some time.
When this happens, it usually leads to faulty operation.
Neutrik XLR and Mini XLR
The Neutrik XLR design became a standard in XLR connectors, as it is more reliable than the original Cannon design.
Today, the XLR cable is one of the most prevalent audio and video equipment connectors, from home studios to professional settings.
The three-pin XLR cable is still the most popular option, but there are wiring schemes with up to seven-pin designs.
Mini XLR cable is also available, which is made to accommodate smaller microphones.
XLR Microphone Cable Parts
At a glance, nothing jumps out when it comes to standard three-pin XLR microphone cable components.
Three core components make up an XLR cable: the wires, cable shielding (rubber outer jacket and filler), and three-pin connectors.
The internal wires or conductors allow the microphone to carry the signal.
Cable shielding protects these wires, which helps ensure that the signal’s integrity is uncompromised during transmission.
Lastly, the three-pin connectors deliver the signal from the microphone to a specific audio interface.
These pins have different roles, which we’re going to identify.
- Positive: Recipient of the audio data in positive polarity.
- Negative: Recipient of the signal in negative or reverse polarity.
- Ground: Protects the positive and negative pins from interference while providing a reference point for the two other pins.
The Advantages of XLR Microphone Cable
XLR cables are not the only choice when it comes to microphone connectivity.
However, there are significant benefits of using this type of cable that others couldn’t deliver.
Now that we have an educated idea of what is an XLR microphone cable is, let’s have a look at its features.
Here are some notable advantages that might convince you to choose an XLR microphone cable over USB and TRS cables.
XLR cable is a type of balanced cable, which enables you to carry a balanced signal or audio.
Before defining balanced audio, let’s clarify that using a balanced cable does not equate to having a balanced signal.
You won’t get balanced audio if your device can’t produce a balanced signal.
It would be advisable to check the specifications of your device output to ensure that it can produce balanced audio.
Balanced audio is a way of linking audio equipment that minimizes environmental noise by using polarity inversion.
Since balanced cables are less impervious to signal loss, a louder signal gets transmitted with more capacity.
Thanks to this attribute, your input device doesn’t need much adjustment to get the preferred volume.
As such, you’ll preserve the dynamic quality of the audio source.
Overall, a balanced connection to the receiving device cancels noise or distortions, resulting in a clear and accurate audio output.
For longer XLR mic cables, the same noise cancellation feature is also expected.
The locking mechanism of XLR microphone cables is one of the distinct features that separate it from other options.
This particular attribute dramatically minimizes unintended pull-outs, which is a common occurrence whenever you trip on a cable.
If multiple wires and equipment clutter your working space, chances are you or other people may accidentally trip on wires.
Having a locking mechanism protects your system from potential damage while ensuring that your connection is as secure as it gets.
Other cables such as TRS cable connectors and USB cables don’t have such features, making them highly susceptible to accidental pull-outs.
Multiple Cable Connectivity
If you’re having issues managing a significantly long wire, the XLR microphone cable has an excellent feature to assist you.
You can connect a series of short XLR cables to have a single-piece cable whenever needed.
By plugging the male XLR end to another cable’s female XLR connector, you’ll have one long, functioning cable.
This feature is essentially impossible for other options such as TRS cable because both cable ends are male connectors.
If you’re recording vocals in a studio, most likely, you’re using a condenser microphone.
This type of equipment is known to capture high-quality, accurate, and detailed vocal input.
XLR cables are the optimal choice for connecting condenser mics into an audio interface to deliver phantom power.
In case you’re not familiar, let’s explore the details about phantom power.
The term phantom power is believed to come from the concept of an “invisible” power supply.
Specifically, it is the process of sending Direct Current or DC voltage to mics that need electric power to operate active circuitry.
Condenser microphones of the past require an additional power supply to run.
The power supply used back then was usually large and heavy and installed near the microphone.
Thanks to the efforts of German manufacturers Schoeps and Neumann, they were able to incorporate mixing boards into the condenser mic.
By adding this component, it effectively eliminates the need for a bulky external power supply.
Up to this day, the mixing board is a standard component in condenser microphones.
- How It Works
As mentioned earlier, phantom power is a DC voltage that passes through the audio wires.
The phantom power uses the same cable which the microphone’s audio signal travels to the mic input to supply the voltage.
Phantom power has a voltage range of 12 to 48 volts and a current range of 4 to 22 milliamps.
The average phantom power is +48 Volts Direct Current, which most professional phantom power sources provide.
A balanced cable such as the XLR microphone cable makes this process possible.
The pin-two and pin-three of the XLR connector act as the signal conductors, while the pin functions as the ground conductor.
- Phantom Power Sources
A lot of audio interfaces and mixers in the market today are capable of providing phantom power.
If your equipment doesn’t have phantom power, you might want to consider a microphone pre-amp.
Not only does this component generate phantom power, but it is also likely to have higher-quality inputs than other standard audio interfaces.
Best Alternatives To the XLR Microphone Cable
After we have enumerated the benefits of XLR cables, it would be hard to argue that it is the best option for microphones.
However, other cables are available for your consideration.
Let’s take a look at other notable microphone cables.
The TRS stands for Tip, Ring, and Sleeve, which are components used on the jack plugs.
Similar to XLR cable, TRS is capable of carrying balanced audio in microphones.
This cable type is available in multiple sizes, but the most prevalent variation is the 1/4-inch connector.
TS and TRRS connectors are related to this type of cable.
While the XLR cable is superior to the TRS cable in terms of overall features, the latter is more versatile.
There was a time that USB connection was pretty exclusive to PC peripherals, but nowadays, it’s one of the most prevalent means of connectivity.
When it comes to design features, a USB microphone cable is similar to the standard USB cables we see on our PC, with one exception.
You’ll see a standard USB connector on one end, but on the other end, most likely, it is a female XLR connector.
USB microphone cables are an indispensable component for streamers and podcast hosts because they usually use USB mics.
To identify the functionality of USB mic cables, let’s look at the design and features of a USB microphone.
A USB microphone has the same components as a standard microphone, such as a capsule and diaphragm.
Integrating two extra circuits, a built-in pre-amp, and an analog-to-digital converter sets it apart from other microphones.
The pre-amp eliminates the need for a mixer or additional mic pre-amp common in condenser mics and other types.
The A/D converter converts the mic’s analog output to digital data, allowing it to be recognized immediately by the computer.
As a result, you can easily edit or enhance your audio file because it is already available on your PC the moment you stop recording.
Because of convenience, USB microphones are the preferred choice for podcasts, dubbing, or streaming.
However, if recording high-quality songs, you’re better off using an XLR microphone.
