This tutorial shows you exactly what you need to know when you want to connect your XLR microphone to your computer (PC or Mac).

We use a Shure SM58, Shure SM7B, and AKG C 3000 B microphone, so you see how different types of microphones work, complete with a demonstration on the computer.

Connect XLR Mic To Computer

Are you looking to connect an XLR microphone to your computer (Mac or PC)? There are many great reasons that you may want to do this:

  • Studio Recording (Garageband, Protools, Ableton, Logic, etc.)
  • Video Conferencing (Zoom, Google Chat, FaceTime, Skype, etc.)
  • Live Streaming (YouTube, Twitch, Periscope, etc.)

Generally speaking, there are two ways to achieve your goal:

  1. XLR To USB Cable/Adapter
  2. USB Audio Interface

We’ll go into both options and let you know why we think the USB Audio Interface is the best way to achieve your goals.

In some circumstances, it may be possible to use a cheap ~$20 cable to plug an XLR microphone into your desktop or laptop computer’s USB input. In our tests, this solution has worked well for handheld dynamic microphones like the Shure SM58.

That being said, we don’t recommend this solution for the following reasons:

  1. It doesn’t offer a lot of gain. This can make it tricky for dynamic microphones like the Shure SM7B.
  2. This would only work for dynamic microphones (Condenser microphones require phantom power).

USB Audio Interface

The USB Audio Interface is the most robust and reliable solution to connect your XLR microphone to your computer.

On the low end, several options for $100-250 will fit your needs:

PreSonus AudioBox USB 96 Audio Interface

All of these options do the same thing. They will give you:

  • Two XLR inputs
  • Independent volume control
  • Main output control
  • Headphone jack
  • Phantom Power for Condenser Mics
  • USB port to connect to your computer

With this option, you can also multitrack record.

This means that if you’re using ProTools, Garageband, Logic, or Ableton, you can record both inputs simultaneously to separate tracks.

This will allow you to adjust the volumes of both tracks (guitar & vocals, for example) after recording them. 

The USB Audio Interface is the best solution for both Mac & PC Computer users.

USB Audio Mixers

A USB Audio Mixer is another great way to connect your XLR microphone to your computer.

With a USB audio mixer, you get the same connectivity as an audio interface, but you get more hardware-based control of your microphone inputs.

Not only do you get more control, but you get more inputs as well. If you need to connect several devices to your computer, an audio mixer is a great option.

If you decide on buying a small audio mixer for yourself, be aware that (most) audio mixers only send the stereo mix to your computer. You won’t be able to multi-track record each input separately.

A USB Audio mixer is more common for:

  • Live Events
  • Live Streaming
  • Video Conferencing
  • Hybrid Events (Broadcasting a live event online).

Some common USB Audio Mixers Include:

Digital Audio Mixer

Recently, digital audio mixers are becoming more common.

With a digital audio mixer you can have more control over more inputs compared to any of the other options in this video.

They give you an all-in-one recording suite, with the ability to record to SD card or connect to your computer.

Digital audio mixers have more on-board processing to help you sound your best, this can include:

  • EQ Settings
  • Compressor
  • Expander
  • DeEsser
  • Noise Gate
  • Etc.

Below are our favourite options for digital audio mixers:

Mic Stand For XLR Microphones

Unless you bought a complete XLR microphone kit, you will need to buy some type of mic stand for your microphone.

There are two options to consider:

Table mic stands are inexpensive and rugged. They do an excellent job of positioning your microphone. The only downside to using a table stand is that it takes up space on your table.

On the other hand, you can use a microphone boom arm which will give you more flexibility with placement. They are easier to use and don’t take up valuable space on the table in front of you.

Below are some options that we love:

XLR Cables

Next, you will need an XLR cable for your microphone.

Not all XLR cables are created equal.

Although most XLR cables “work”, here are some things to look for:

  • Four conductors inside the XLR cable (Star Quad)
  • High-Quality Shielding
  • Good Amount of Flexibility
  • Durable Connectors, preferably black.
