XLR Cable: All You Need to Know XLR Cable as a Balanced Cable

How well do you love good sound production? Sounds are pleasant and musical to the ears when it emanates the right way. The ideal cable type to help with this is the XLR cables.

XLR cables are cables that work well with some microphones and speakers. The cable is quite similar to the TRS cable, but there are still differences. The XLR cables are essential for sound production unusually, over long distances.

This cable type seems quite challenging, but in reality, they are one of the most natural types of cable to handle. If you want to get the very best from the XLS cable, you need to understand how the XLS cable.

Chapter 1: What is an XLR cable?

  • What is an XLR cable?

Another name for XLR cable is microphone cable. It is also a balanced cable type. The XLR cable is notable for its three pins and one circular connector.

The three pins of the XLR cable represent three dimensions. Such as positive, negative, and ground.

The XLR cable is very identical to TRS cable; that is, Tip ring sleeve cable.

Interestingly, these cable types are essential in producing accurate audio signal transmission. That is, it transmits sounds without the presence of electrical interference.

Therefore, the balanced signal preserves the audio signal in its original form.

  • How does it work?

As earlier stated, the XLR cable is a balanced cable type. As such, when you connect two balanced cables, the XLR cable produces three different signals as positive, negative, and audio signals.

Amongst the three audio signal types, the most identical are the negative and positive signals. The only difference between these two signals is that they are inverted.

This presupposes that when there is any electrical interference of any sort, it affects both the positive and negative audio signal. Thus, if the positive or negative signal gets to the end of the balanced cable, one of them becomes inverted.

Hence, both the positive and negative signal is very similar, but the presence of noise disrupts the full capability of one. As such, when the disrupted sound comes in contact with the original noise, there are changes. The resultant effect is that the original audio signal is left.

  • What are the uses of XLR cables?

The XLR cables are suitable for studio and live sound applications. This is because the XLR cables are a balanced type and permit this ability.

Thus, if a personal address system is a considerable distance away from an amplifying band, the XLR cables are most efficient. More so, the XLR cables connect easily to microphones.

Microphones require the use of phantom power. Microphones make use of mixing boards that generates electricity. The essence of the XLR cables is to create the right amount of energy to the microphone. Additionally, the XLR cables are most useful for line-level signals over distances.

Chapter 2: Balanced Cable and Unbalanced Cable

  • Unbalanced cable

Unstable cable types possess two different wire types that function as the conductors. The conductor transmits both the audio signal and ground signal.

One major benefit of the unbalanced cable is that it is very affordable. However, they are susceptible to electrical interference. When there are other electronic devices nearby, it disrupts the transmission of audio signals. These cable types are not compatible with audio applications that are meant for long distances.

  • When to use unbalanced cable

Balanced cables are suitable for short distances. The short distance reduces the presence of external interference. Examples are guitar and speaker cables. Since these cable types are best for short distances, it is still best to play safe.

To minimize the presence of the noise, the best thing to do is to avoid radio towers and keeping your distance from power cords.

  • Balanced cable

The balanced cables possess three wires. The three different wires serve as conductors that represent negative, positive, and ground signals. The audio signals are suitable for negative and positive cables. Though, they transmit this signal with contradictory polarities. This implies that if there is any external interference, it is ruled off. Balanced cables are best for any audio application that requires long distances.

  • When to use balanced cable

Balanced cables are suitable for long distances. The XLR cable is best for the balanced cables. The best example of a balanced cable is the microphone cable. Long cables are more easily prone to noise. That is why it advisable to make use of balanced cables.

  • XLR cables as balanced cable

XLR cables are unarguably a balanced cable type because they transmit audio signals over long distances. However, XLR cables are capable of transmitting balanced signals if the signals at the other end of the wires are also balanced.

In the situation where any of the signals at the end of the chain is unbalanced, it affects the entire process and causes it to be unbalanced.

  • Similarities of balanced and unbalanced cable

The balanced cables and unbalanced cables possess a protective layer known as shields. The shields of these cable types are suitable to protect the wires from the interference. The typical examples of external interference are radio-frequency interference and any external interference.

In most cases, the high-frequency sounds/noise emanates from the radio-frequency interference while the low-frequency interference emanates from the electromagnetic interference.

Chapter 3: Different Types of XLR Cable

In the earlier part of this book, I clearly explained the balanced and unbalanced cables. The examples of balanced cable types are Speaker cables and microphone cables.

There are two different types of XLR cables which also happen to be examples of balanced cables. The various types of XLR cables are:

  • The XLR speaker cable
  • The XLR microphone cable

Though both XLR cable types possess the same kind of connector, they function differently and at various capacities. If you desire to get the right output, it is essential to get the ideal XLR cable type and use the correct specification.

  • The XLR speaker cable

This XLR cable type is suitable for unshielded conductors. This implies that the XLR speaker cable is best for positive and negative wires.

Speaker cables are not shielded or balanced. More so, they are not compatible with other types of connection regardless of the connector type.

  • The XLR microphone cable

This XLR cable type consists of negative and positive conductor wires. It also possesses a three shielded ground wire with a three-pin connector for audio connection. The various examples of XLR microphone cable are musical instrument, sound mixers, microphones, and, other power amplifier input.

XLR cable type is suitable for professional use. The benefit of the XLR microphone cable is that it permits the use of the wire over long distances. Also, it minimizes the presence of electronic interference.

To avoid any form of disaster, microphone cables are not compatible with speakers. The only time that you make use of microphone cable to a speaker is when it is a powered speaker. Powered speakers consist of the internal amplifier. It suits the balanced XLR microphone cable.

A good number of XLR cable possesses a balanced XLR input jack. The powered speaker is not compatible with unshielded speaker cable as the absence of shield will result in distorting noise.

  • The dangers of substituting one type of XLR cable with another

Connecting the XLR speaker cables to a microphone hampers with the production of sound. The incompatibility of the cable type results in distorted sounds and possibly causes damage to the equipment.

Furthermore, connecting the XLR speakers to microphone cables also leads to poor sound output. That is, the cable becomes unable to carry higher speaker voltage. The effect of this is that it damages the amplifier of the speaker.

To avoid unpleasant situations, the best thing to do is to make use of color-coding to identify the different types of XLR cables.

Chapter 4: XLR Cable and TRS Cable

The big question is, “Is there a difference between an XLR cable and TRS cables?” Many individuals still encounter difficulties recognizing the differences between XLR cables and TRS cables because of the similarities both cables share.

Some cable types possess two different cable types on different ends. That is, on one end is an XLR cable, and the other end is a TRS cable. Irrespective of the various forms of the cable, there are still visible differences between the two cable types.

While many argue that there is no difference between the XLR cable and TRS cable, the reality is that there are differences between both cable types.

Some major differences are:

XLR cables are good examples of balanced cables which are also referred to as twisted shielded pair cables. The TRS cables, on the other hand, are examples of unbalanced wires and are also suitable for headphones. Therefore, the TRS cables are not compulsorily shielded.

Additionally, XLR cables are the best bet for longer distances. They are suitable for preventing external interference that is brought about by wrong signals. This cable type helps to avoid the problems of distance in good signal transmission. The TRS cable cannot perform the same function as the XLR cables. That is, it cannot function as an extension cable over long distances because it is not a balanced cable.

In line-level connections, it is only possible to connect a TRS cable to a TRS cable, but for an XLR cable, it works well with other types of wire.

Chapter 5: Where to Buy XLR Cables From

The XLR cables are a unique type of wires. Since they are very common because of its uses and functions, many people find it challenging to make use of the cable.

The XLR cable types are sometimes confused as TRS cables, and this makes it more challenging for people to use. The consequence of not handling this cable the right way is that it affects the sound production from the computer and possibly destroys the musical equipment.
