How to Connect a Condenser Mic to a Computer?

Perhaps the most noticeable difference between a condenser and a dynamic microphone is that the condenser microphone needs phantom power, whereas the dynamic microphone doesn’t. 

Even though the two microphones are different in terms of their components, (but also in the way they draw power), how you connect them is practically the same, in fact, if you’ve read my article on connecting dynamic mics, you would already understand 99% of the process. So how do you do it anyway?

To connect a condenser microphone to a computer, you have to first connect an audio interface that has phantom power. You then run an XLR cable from the audio interface into your condenser microphone. Make sure you turn on the phantom power button and also use a pop filter and shock mount.

It really isn’t more complicated than that, however, I’ll make sure to run through this process, step-by-step. I’ll also include some of the other items you may need to get your connection up and running, in addition to some condenser microphone alternatives that don’t require an audio interface.

Gear You Need to Connect A Condenser Mic to Your Computer 

1) An Audio Interface (Focusrite Scarlett 2i2) 

Focusrite Scarlett 2i2 Main Image

The Focusrite Scarlett 2i2 (also on Amazon), is the most popular audio interface because it’s the most reliable and probably because it looks cool as well. The most recent model – the third generation – is smaller than the previous generations and has more of a sleek design. I couldn’t recommend it enough (in fact I already have). It’s a great little audio interface. 

2) Condenser Microphone (Audio Technica AT2035)

If you’re on this page, there’s a good chance you already own a condenser microphone but assuming you don’t, the Audio Technica 2035 is a great choice (also on Amazon). I recommend it simply because I own one and I can personally vouch for it. Maybe there are better mics on the market. That could certainly be the case, but I know for a fact this is a good one. 

3) XLR Cable (Any Brand, but D’Addario is Great) 

XLR-Cable-

An XLR cable is the standard cable that nearly all mics use for their connection, whether it’s a dynamic, condenser, or ribbon microphone (except for USB mics). For that reason, you can really never have too many of them. The D’Addario cable (on Amazon as well) is a great option and it doesn’t cost a lot of money either. I would say the 10-foot cable is enough unless you know you need something longer. 

Optional 

4) USB to USB-C Adapter

This is an essential piece of equipment that I use practically on a daily basis. If you have a MacBook Pro or some other similarly modern device, there is a good chance that you already own an adaptor like this, but if you don’t, they go for a good price on Amazon. This is the adapter that your audio interface will need to connect to. 

5) Boom Arm, Wind Guard, Pop Filter, Shock Mount, Phone Holder

I bought this set recently from Amazon and I think it’s fantastic for what it costs. The price is right, and thus far, it’s doing just fine for what I need it for. It comes with a boom arm, a pop filter (that I desperately needed), a phone holder, a wind guard, a shock mount, and a 5/8″ adapter in case your mic has a different sized thread.

Connecting A Condenser Microphone to a Computer (A Step-By-Step Guide) 

1) Connect the Audio Interface to Your Computer 

First, connect the USB to USB-C adapter to your computer, and then use the Thunderbolt to USB cable that the Focusrite Scarlett 2i2 comes with to connect it to the adapter. From there, you should notice that the audio interface will turn on and light up on a few of its buttons, including on the “Gain” knob. 

2) Connect the Mic to the Audio Interface Via XLR 

Grab your XLR cable and run it from the microphone to your audio interface. I would also make sure the gain knob is turned down just a little bit, just as a general rule. There’s no sense in plugging into something with the volume cranked. I find that a good rule of thumb is to have the gain set to around half-way once you’ve started using it.

3) Turn on the Phantom Power Button 

Phantom-Power-Light-Scarlett-2i2-

This one is self-explanatory, just hit the phantom power switch. It’s the button that says “48 V” over top of it. Once you’ve selected it, it should also turn a different color. If you’ll recall what I said at the start of the article, you’ll know this is the primary difference between the condenser and dynamic microphone in terms of its set-up. You don’t need phantom power for a dynamic microphone. 

4) Because Condenser Mics are Sensitive, It’s Best to Use A Shock Mount

It’s best to use a condenser mic with a shock mount of some kind. Whether you get it from the set I mentioned above or as part of the mic purchase, it isn’t all that important. What matters is you use a shock mount, because condenser microphones are more sensitive to subtle details and nuances. In fact, this is the defining feature that makes it different from dynamic microphones. 

Condenser mics like the AT2021, for example, are for acoustic guitar recordings and they’re great at picking up on those little intricacies that perhaps a dynamic mic wouldn’t capture as well. 

An unintended consequence of this is that the mic tends to pick up on desk bumps, the sound of the mic being moved around, etc. Put simply, a shock mount prevents the microphone from picking up extraneous sounds like when your knee hits against the desk, for instance, or when you accidentally touch the mount with your hands because you forgot how sensitive the mic is.

5) Go into Your System Preferences to Set Up the Input 

If your computer, for whatever reason, isn’t recognizing the microphone, make sure you go into the System Preferences and see if you can fix it in there. 

System Preferences Plug-Ins

Select “Sound,” and then go into the Input section, and select the option, “Focusrite Scarlett 2i2,” or whatever audio interface it is that you’re using. The same thing could be said if you were connecting it to a DAW of some kind as well, like Garageband, for example.

And that’s pretty much it for connecting a condenser microphone to a computer. Additionally, there are alternatives to this type of connection, including a USB condenser microphone like what we’ll explore in the sub-section below. 

Alternatives for Connecting a Condenser Microphone to a Computer

1) USB Condenser Microphones (Audio Technica AT2020USBPLUS)

If you don’t want to use an audio interface for whatever reason like if you’re not interested in a home studio and you just want to use a condenser microphone without all of the other gear, you could use the AT2020USBPLUS from Audio Technica (also on Amazon). Essentially, it’s a similar microphone to the 2035 but it’s USB-connection only.

 The AT2035 is going to sound a bit better than this one, but regardless, if you don’t want to use an audio interface, there are other options. A lot of people don’t necessarily want or need an audio interface, because maybe they’re only interested in using a mic for conference calls or Zoom meetings. An audio interface like the Focusrite Scarlett 2i2 is going to come in handy for many of us who are into music and audio. 

Important Things To Understand About Condenser Mics 

1) Always Make Sure the Phantom Power Switch is Turned On 

Phantom-Power-Light-Scarlett-2i2-

While it may seem obvious (because it is), you always want to make sure this button is turned on because otherwise, it’s not going to work as well as it could. If you find yourself wondering why your microphone isn’t working that great, it’s very possible this is the culprit. A condenser microphone needs phantom power to work at 100% of its potential, otherwise, you’re going to need to crank the gain after the fact to hear it.

2) Change System Preferences in Your DAW

System-Preferences-Edited-

Assuming you’re using a condenser microphone for a podcast or music production, you’ll also have to go into your digital audio workstation’s system preferences and change the input and output so it uses the microphone and the audio interface instead of the internal mic/speakers of the computer.

On a Mac, this is done in the System Preferences, whereas on Windows, it’s done in the Windows Control Panel. It’s worth mentioning that if you choose to use a USB condenser microphone, rather than the audio interface being shown in the System Preferences/Control Panel, it’ll say the name of the specific mic.
