Connect Shure MVX2U XLR Mic Directly to Your PC
Index
Many streamers and VTubers want to use XLR microphones (like the SM7B or SM58, commonly used by professionals) easily. However, they often hesitate to place an “audio interface” on their desk due to space constraints. This is a common concern among content creators.
The Shure “MVX2U” is a device designed to address this issue. It’s not just a simple adapter to convert XLR microphones to USB-C; it’s a compact device that provides professional-quality audio processing.
In this article, we will explain how the MVX2U can transform your streaming setup, along with practical usage examples.
I’m a bit worried… setting up my streaming environment might make my desk get really cluttered.
True, audio interfaces do take up space. But with this MVX2U…
Wait, such a tiny device is actually an audio interface!?
Yes! It looks compact, but it’s fully professional inside. You can keep your desk neat, and setup is super easy. Let me introduce it right away.
What is the MVX2U? — A Compact Device to Keep Your Desk Neat
The MVX2U Revealed: A Tiny Audio Interface
An audio interface is an essential device for high-quality streaming and recording, converting analog signals from microphones or instruments into digital signals your PC can process.
The Shure MVX2U might look like a simple “adapter that converts XLR mics to USB-C,” but it’s actually a fully-featured compact audio interface. It amplifies mic signals, automatically adjusts audio quality, and allows you to monitor your voice through headphones—all built into one small device.
It achieves the functionality of traditional box-style interfaces in a size that plugs directly into the base of your microphone.
Key Specifications of the MVX2U
Despite its compact appearance, the MVX2U houses all the essential features found in standard audio interfaces.
This means you can achieve professional-quality sound simply by “plugging it in like an adapter.” Here are the main specs of the MVX2U:

All-in-One Features for Streaming Beginners
The MVX2U is “small in appearance, professional inside.” Despite its compact size, it packs all the features needed for streaming.
- Clean Gain up to +60 dB
This means it can boost your voice without adding extra noise like the typical “hiss.” Some popular professional microphones actually output very low levels when connected directly. The MVX2U provides enough amplification for these mics without any additional equipment. - +48V Phantom Power
Supports high-sensitivity condenser microphones that require external power. - 3.5 mm Headphone Jack
Monitor your voice in real time with zero latency while streaming.
Designed for Creators Who Want to Hide Their Gear
It’s aimed at anyone who wants the sound quality of a professional XLR mic without adding bulky equipment to their desk.
The essence of the MVX2U is that it miniaturizes the “box” of an audio interface and hides it at the base of the mic, so users don’t even notice the interface is there.
It’s amazing that my desk stays clutter-free…!
Exactly. All the audio processing happens inside this tiny unit, so it’s easy to forget it’s even there.
I love it—my desk stays tidy, and the audio quality is on par with professional setups!
Pros and Cons of Using MVX2U
The MVX2U is a powerful device, but its advantages and disadvantages go hand in hand.
Operational Advantages and Limitations
Pros: Easy to use with automatic audio adjustment
Simply connect it to your PC via a USB-C cable. For basic use, no app installation is required.
(Installing the MOTIV Mix™ app is necessary only for advanced settings)
- Automatic Level
Just set your distance from the microphone, and the volume adjusts automatically. This prevents audio from being too quiet or distorted. - Manual Control
For advanced users, you can fine-tune audio quality, prevent clipping, and balance voice levels. - Key Strength
Settings made in the MOTIV Mix™ app are stored directly on the MVX2U. Once configured, your adjustments apply automatically across OBS, Discord, Zoom, Teams, and other apps—without reopening the app. This means you can save your settings on a home PC and then plug the MVX2U into a laptop to instantly replicate the same audio setup.
Cons: Limited on-device control
- There are no physical volume controls; all adjustments are made through the MOTIV Mix™ app.
- If you need to quickly change volume during a live stream, opening the app can be cumbersome.
- Compared to other MV series models, there are fewer adjustable settings.
These limitations are intentional, designed to keep functions minimal and prioritize stable operation: once set, you rarely need to adjust them.
Use Case Advantages and Limitations
Pros: Tailored for streaming
- The device focuses only on essential streaming functions, making it beginner-friendly.
Cons: Not suitable for music production or gaming consoles
- It’s not ideal for professional music production (there’s slight audio latency).
- It does not support connections to PlayStation, Xbox, or Nintendo Switch.
When used exclusively for streaming, it’s an extremely simple and user-friendly device.
Tested with a Professional Microphone (SM58 + MVX2U)
Is setting it up a bit tricky…?
Basically, you just plug it into USB. The app is only for those who want to tweak settings in detail. In fact, it’s designed so beginners can get great sound without overthinking.
Hey Umazura, you actually tried it out, right? How did it feel?
Exactly. From here, I’ll walk you through what we discovered during our hands-on testing.
No Worries Even with Low-Volume Mics
Some professional microphones produce extremely low volume when connected directly to a PC. Traditionally, you’d need additional amplification equipment (a booster) to bring the levels up.
MVX2U Works Without Extra Gear
The MVX2U features a built-in +60dB gain, which is enough to boost even low-output microphones to a proper volume. In practice, setting Auto Settings > Mic Gain > “High” delivers sufficient power to pick up soft speech clearly, making it perfectly usable for home video calls at this setting.
Things to Keep in Mind
The MVX2U is excellent, but there are a few points to be aware of.
- Be cautious with Mic Gain > “High”
The “High” setting amplifies background noise (like a constant hiss) even when you’re not speaking. For stable streaming, it’s best to start with the “Normal” setting and adjust from there.
- Handling Noise
Increasing mic gain also amplifies handling noise (the rustling or scratching sounds when touching the mic). If this is an issue, lower the gain or use a noise-reducing microphone or mic arm to avoid contact with the microphone.
Other noise can be addressed using the MOTIV Mix™ app. Setting the “High-Pass Filter” to 75Hz cuts low-frequency background noise, making environmental sounds negligible. Combined with the noise suppression features in your streaming software, this setup is fully practical.
Collaborative Podcasting with Multiple Units
Both Windows and Mac support connecting two or more MVX2U units simultaneously. Each is recognized as a separate microphone, allowing for dialogue-style podcast recordings. Note that some applications may not recognize multiple units, so test your setup in advance.
Reference: Shure Official Support – Can I connect multiple MV7 mics to my computer via USB-C?
Can It Be Used with Smartphones?
Using the MVX2U with smartphones or tablets (iPhone/Android) is officially not recommended, though some users have successfully tested it unofficially. Considering its compact size, it’s a shame it isn’t fully mobile-compatible, so we hope future models will support this.
MVX2U Setup and Usability
Here’s a basic guide to getting your MVX2U ready for immediate use with a microphone.
Three-Step Connection
- Connect your XLR microphone directly to the MVX2U (or via an XLR cable).
- Connect the MVX2U to your PC using the included USB-C cable. The LED turns green when ready.
- Plug your headphones into the MVX2U’s 3.5mm jack.
First Steps in the MOTIV Mix™ App
Check Phantom Power
The MVX2U has phantom power (+48V) enabled by default. Adjust this setting based on the type of microphone you’re using.
- For dynamic microphones (which don’t need power)
Turn off phantom power in the app.
※Ribbon microphones are especially sensitive—always double-check. - For condenser microphones (which require power)
Keep the default “On” setting.
Set Microphone Position:
Start with Auto Settings > Mic Position > “Near”.
For More Fine-Tuned Control
If your audio is unstable or you want more control over your sound, switch to “Manual” mode to access the following settings:
- High-Pass Filter: Setting it to 75Hz or 150Hz cuts low-frequency noise from air conditioners or PC fans.
- Limiter: Turning it on prevents distortion even when shouting.
- Compressor: Setting it to “Medium” reduces the volume difference between soft and loud speech, making it easier to listen to.
No Physical Buttons
The MVX2U has no volume knob or mute switch. While this may seem inconvenient, it’s designed to prevent accidental adjustments. Once set up via software, your settings remain stable, ensuring reliable operation.
Similarly, features like ASIO and multi-channel input for music production are omitted, resulting in a design focused on reliability for live streaming and video conferencing.
MVX2U Summary
The MVX2U is an extremely user-friendly USB audio interface for beginners who want to use XLR microphones. It combines high-quality, low-noise audio with simple operation, making it perfect for anyone who just wants good sound for streaming.
The minimalist, button-free design may divide opinions, but for live streaming and meetings, it offers the advantage of stable, unchanging settings. Shure’s characteristic reliability shines in sound quality, making it stand out in its price range.
Conclusion: Who Should Consider This
- Those who want to use professional microphones without struggling with complicated settings
- Streamers or VTubers who want a clean and organized desk setup
- Anyone looking for a microphone that automatically adjusts volume
- People who want consistent audio quality at home and on the go
Placing the interface out of sight—that idea perfectly reflects Shure’s design philosophy.
On the other hand, there is a slight audio latency, so it’s not ideal for serious music production or for connecting directly to gaming consoles (PS5/Xbox/Switch are not supported).
When used appropriately, the MVX2U acts as a convenient bridge between professional microphones and streaming software, handling the tricky settings for you. Definitely consider it as an option.
