Does XLR to USB Reduce Sound Quality?

XLR produces professional-grade sound. So, many people are concerned with the loss of quality when converting XLR to USB, but is there any loss? 

Converting XLR to USB can reduce sound quality. Anytime you are converting audio through different formats, there is a chance of audio quality loss. Moreover, XLR microphones are usually more powerful and provide higher quality than USB. Therefore, the conversion is likely to lead to quality loss. 

Let’s take a closer look at the process of converting XLR to USB and how it affects sound quality.

Why Does Converting XLR to USB Reduce Sound Quality?

Converting XLR to USB reduces sound quality because you are transferring audio from one format to another. XLR is analog, while USB is digital. So, to convert audio from one format to another, it must be broken down and reconfigured. During this process, it is common for some quality to be lost. 

Many people prefer to use XLR microphones to record music or sounds. Because it isn’t possible to just plug your XLR microphone into a computer, the audio needs to be converted to a type of media that your computer can read. 

Transferring audio to digital is what allows it to be shared everywhere, from CDs to your phone or iPod. So, converting audio is necessary for it to be heard and shared on digital platforms. But many people still prefer to record on an XLR mic because they prefer the quality. 

Think of converting sound like translating a book. Depending on who translates the text and how well they understand the languages, the translation could be poor. This is the same for converting sound. The quality of the materials you use will determine whether the sound quality is poor or not. 

You can have a great microphone, but the sound quality may still suffer if your cable is not great quality. As the sound travels through the cable to be converted, a cheaper cable could make it lose quality. Your cable may be compromising the quality of sound as it travels through the cable and is converted to digital. 

There are significant differences between XLR and USB sound:

  • XLR is analog, while USB is digital.
  • XLR audio is balanced. This means that the sound is clearer and clean. 
  • XLR audio is noise-canceling, so you don’t have to worry about outside interference. 
  • USB sound is unbalanced. This means it is not as crisp as XLR, and it is more susceptible to outside noises. So, during the conversion process, your audio will be more vulnerable to interference from nearby frequencies. So, the better the converting cable, the better quality you will get once the audio is converted.

How Do I Find a Quality Adapter for My XLR Mic?

Finding the best adapter to convert your XLR microphone audio to USB depends on your microphone and the quality of the cable. If you have a dynamic microphone, then a cable is all you need. However, condenser microphones need a preamp to provide phantom power. Quality is vital for whichever method you use to convert. 

XLR to USB Microphone Audio Converter Cable

For dynamic microphones, all you need is a cable to convert your XLR audio to USB. The quality of the cable is crucial because it is where sound will travel through to be converted. The conversion process is essential, and a lot of quality can be lost along the way. 

There are cheaper and more expensive versions depending on what your budget is like, but it is important to be aware that a good quality cable is not going to make up for poor quality audio equipment. So, even the best cable won’t help sound quality if you have cheaper equipment. 

For a quality, inexpensive option, consider the Behringer Mic 2 USB Interface Cable Opens in a new tab.available on Amazon. This simple yet sturdy cable can undoubtedly get the job done when trying to convert your audio.

This is an excellent choice for an inexpensive option that can still get the job done with as little sound reduction possible. But if you have a condenser microphone, then there is more you need.

Condenser Microphones Need an Adapter

Condenser mics need phantom power to handle electric currents running through them. Phantom power is the process of delivering direct currentOpens in a new tab.. It is not required in dynamic microphones because they power themselves. Condenser mics need phantom power to work. 

Cables like the one above do not include phantom power. So, your condenser microphone will need an adapter that contains phantom power. Thankfully they are pretty easy to get, but they are generally more expensive than a converter cable because they do more work. 

If you are looking for a suitable adapter that can provide phantom power to your condenser microphone, then check out the Shure X2u XLR-to-USB Signal AdapterOpens in a new tab. available on Amazon. This adapter features phantom power to power your microphone and plug-and-play connectivity for easy use.

Why Do People Still Use XLR Over USB?

People still use XLR despite needing to convert their audio to digital format because it produces a clean sound without much interference. Also, when using XLR, you don’t need to be connected to a computer. It allows you the freedom to work on the go rather than being powered by a cable connected to a computer. 

Reading about the loss of sound quality when converting audio can make you wonder why people still use XLR rather than just recording digitally. There are many reasons that people still choose to use this method:

  • Unlike USB micsOpens in a new tab., XLR allows you to connect multiple microphones at one time. This makes interviews and groups easier to manage as each person can be comfortable with their own microphone. 
  • USB does allow more than one mic to be connected, but all mics need to be connected to a computer. So, it may be uncomfortable for guests because they can’t talk to you from a reasonable distance. XLR does not require that connection to work. 
  • Overall, the quality of XLR is something that people don’t want to sacrifice. While there is a chance that audio quality will be reduced when converting it to digital, people still choose to use XLR because it is of better quality.

Final Thoughts

Converting XLR to USB does reduce sound quality. However, many people still choose to use XLR because of the quality of the audio. 

Converting to USB is a relatively simple process. With a dynamic XLR microphone, all you need is a converter cable, but with condenser mics, you need an adapter. 

Try out the converters above for good quality converting if you want the best possible sound. The better the converter, the fewer audio quality issues you will have. So, even though the sound quality may suffer, there are ways to help.
