Audio-Technica AT2020 XLR Microphone: Buying Guide

The Audio-Technica AT2020 is a cardioid condenser studio microphone with an XLR output. That description tells you most of what decides whether it fits your setup. It needs phantom power. It needs an audio interface or mixer between it and your computer. Like most condensers, it also tends to pick up the room along with your voice. This guide covers each of these points so you can decide before you buy.

Start with the intended use

Begin with what you will record and where. A spoken-word podcast in a quiet, furnished room needs a different setup than video calls at a desk with a loud PC fan and a mechanical keyboard. Vocals and acoustic instruments are other common uses. Write down the result you want before you compare products, for example clear voice on calls, a clean podcast track or a demo recording.

• How many people will use microphones at the same time?
• How much background noise does the room have: traffic, fans, echo off bare walls?
• Will the mic stay in one place on a stand or arm, or do you need something portable?
• Do you already own an audio interface or mixer with an XLR input?
• Do you want a single cable to your computer, or are you comfortable with an interface in the chain?

If your only goal is better audio on video calls with as little gear as possible, an XLR microphone adds an interface and a cable to your setup. Audio-Technica also sells USB versions under the AT2020 name. Make sure the listing you are viewing is the XLR model if that is the one you want, and choose a USB model if plug-in simplicity matters more than expandability.

Features that matter

Cardioid pickup pattern: a cardioid mic is most sensitive to sound arriving from the front and least sensitive to sound from the rear. This reduces background noise from behind the mic but does not remove it. Placement matters. Aim the front of the mic at your mouth and keep noise sources behind it. The manual shows which side is the front, so confirm it there.

Condenser design: condenser microphones are generally more sensitive than typical dynamic microphones. That sensitivity captures detail, but in an untreated room it can also capture echo, keyboard clicks and other people talking. If your room is noisy and you cannot change it, a dynamic microphone may suit you better.

Analog XLR output: the AT2020 XLR sends an analog signal. It has no sample rate, bit depth or gain control of its own. The audio interface's converter sets the sample rate and bit depth, and the interface's preamp gain sets the input level. The quality of the interface is part of the result you will hear.

Published specifications such as frequency response, sensitivity and maximum sound pressure level describe the design under the manufacturer's test conditions. They help you compare models, but they are not a quality score. They also cannot predict how the mic will sound in your room with your voice.

Check what the box includes for the specific listing, such as a stand mount, a pouch or a cable. Do not assume an XLR cable is included. Also budget for a microphone stand or boom arm, and consider a pop filter if you speak close to the mic.

Check compatibility

The signal chain runs from the microphone through an XLR cable to an interface or mixer, and from there to your computer, usually over USB. Your operating system and apps see the interface as the input device, not the microphone itself. Compatibility therefore depends almost entirely on the interface you pair the mic with.

• XLR input on the interface or mixer, either a dedicated XLR socket or a combo jack.
• 48V phantom power available on that input, with a switch you can find and turn on.
• Enough clean preamp gain to reach a usable input level for quiet speech.
• Driver or class-compliant support for your operating system, confirmed on the interface maker's own documentation.
• A connector that matches a port on your computer, or a supported adapter.
• A power source: bus power from the computer or a separate adapter, depending on the interface.
• A headphone output if you want to monitor yourself or use the interface as your output device.

After setup, select the interface as the input device in your operating system's sound settings and in each call or recording app. Many apps keep their own device choice. Some multi-input interfaces show up as a stereo device with the mic on one channel only. If listeners hear you on one side only, look for a mono or input channel option in the app or the interface software.

If your interface has control software, set its sample rate to match the rate used by your operating system and recording app where possible. 44.1 kHz and 48 kHz are common choices. Mismatched settings between layers can cause problems that look like microphone faults.

Avoid passive XLR-to-3.5 mm cables that plug into a laptop's headset jack. They do not supply phantom power, so a condenser mic like the AT2020 will not work properly through them. XLR-to-USB adapters exist, but confirm that a given adapter provides phantom power before relying on it.

Build a shortlist

Turn your answers from the first section into a requirements list. Check the AT2020 and any alternatives against it. Any product that misses a must-have item drops off the list, whatever its reputation.

• Use case is mainly voice or instruments in a reasonably quiet room.
• You accept that a condenser will capture some room sound and can position the mic to limit it.
• You own, or will buy, an interface or mixer with an XLR input and 48V phantom power.
• The interface supports your operating system and connects to your computer.
• You have a stand or arm, an XLR cable and, if needed, a pop filter.
• The listing clearly names the XLR version, not a USB variant.
• The seller states the box contents, warranty terms and return policy.

Some answers point away from this mic. If your room is loud and untreated, put dynamic microphones on the shortlist. If you want one cable and no interface, compare USB models. If several people need to record at once, make sure the interface has enough XLR inputs with phantom power for every microphone.

Before you order, recheck the exact model name and box contents on the listing, and confirm the seller offers manufacturer warranty coverage in your region. If the AT2020 XLR passes every item on your checklist, it is a reasonable candidate. If it fails one, choose the alternative that meets the requirement you cannot compromise on.
