How we ranked these mic preamps
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

- 48V phantom power weight 1
Buying advice: USB mic preamp
Count mic preamps before buying
A USB mic preamp must have enough preamps for every mic you record at once. The Shure MVX2U has 1 channel for one mic, and the Focusrite Scarlett 2i2 Studio has 2 mic preamps for 2 mics. The BEACN Studio sends up to 8 channels between computers, so it suits a setup with more than one computer. Count mics first, then match the preamp count.
Check phantom power for condenser mics
Condenser mics need 48V phantom power, and dynamic mics do not. The Shure MVX2U has 48V phantom power with up to 60dB of gain, so it covers both dynamic and condenser mics. The Focusrite Scarlett 2i2 Studio has 2 mic preamps with Air modes, and the BEACN Studio has on-board DSP for shaping a mic signal. If you use a condenser mic, confirm your pick supplies phantom power.
Compare monitoring and software bundles
Monitoring and software change how you record. The Shure MVX2U has zero-latency monitoring through a 3.5mm headphone jack, and the Focusrite bundle adds SH-450 headphones for listening back. The Focusrite bundle also has Pro Tools Intro+, Ableton Live Lite, Cubase LE and Hitmaker Expansion, while the Shure MVX2U works with the ShurePlus MOTIV Desktop App. The BEACN Studio uses the BEACN app to manage audio routing between computers.
Frequently asked questions
Do I need phantom power for a dynamic mic?
No. Dynamic mics do not need phantom power, but condenser mics do. The Shure MVX2U supplies 48V phantom power, so it covers both mic types.
Can I use one XLR mic with a computer?
Yes. An XLR-to-USB interface links the mic to the computer, like the Shure MVX2U with 60dB of gain. The Focusrite Scarlett 2i2 Studio links 2 mics, and the BEACN Studio links an XLR mic over USB-C.
What is Auto Gain on an interface?
Auto Gain sets the recording level for you, so you do not set it by hand. The Focusrite Scarlett 2i2 Studio has Auto Gain with Clip Safe, which guards against clipping.
Can I send audio between 2 computers?
Yes, with the BEACN Studio. Its dual USB technology sends up to 8 channels of digital audio between computers, consoles and phones. The BEACN app manages where that audio comes from and goes to.
