Thank you to Universal Audio (specifically the folks over at Glow Marketing) for sending the Volt 2! I am not being compensated for this review; just giving my thoughts and opinions on the unit.

Greetings mate and Welcome aboard!

Stuart Charles here, HomeStudioBasics.com helping YOU make sound decisions leading to a beautiful audio experience that will make you fall in love with music (NOT gear) all over again, so…

I previously owned a 1st generation Focusrite Scarlett 2i2 but had to sell it due to incompatibility issues with Windows 10.

It’s strange to say, but I’ve been Audio Interface-less for a few years now, and it doesn’t feel quite right – especially considering how much I love to rap, do voiceovers, record audio, and play the guitar.

Sure, I’ve been using my Yeti a lot, but it’s not the same.

There’s something special about plugging an XLR cable into an interface that feels second to none.

Plus, you know the sound quality is going to be better than just plugging straight into your PC via USB.

So you can imagine how elated I was when the kind folks over at Glow Marketing emailed me out of nowhere asking if I’d like to review the Volt 2!

“Boy howdy, would I!!”

That wasn’t my reaction in the email as they’d probably not respond back LMAO.

In any event,

I’m excited to give you a rundown of this unit and determine whether or not it’s worth a purchase.

By the end of this article, you’ll know definitively.

We’ll run some mic tests, I’ll tell you how it sounds via headphones, and I may even play some guitar for you as well. 

So let’s dive in, shall we?

What is it?

Universal Audio Volt 2 Review

I suppose it would be helpful to explain what the heck this thing actually is if you’re new to the world of audio.

The Volt 2’s technical name is an audio interface, but you can simply think of it as a few things rolled into one:


It’s a DAC, or a digital-to-analog converter – converting digital information that your PC understands into language that you understand (analog).


It’s also an ADC or an analog-to-digital converter. So in addition to the above, it also converts your voice via microphone (analog sound) into a language that your PC understands (digital).


It’s a preamp, meaning it has balanced outputs that can connect to separate powered speakers like the JBL LSR305, Yamaha HS7, or Presonus Eris e3.5.

Phantom Power

It has 48v phantom power which condenser microphones need to sound loud enough. What Is 48v Phantom Power?

Now that we know what it is, let’s discuss build quality.


Right off the bat, the Volt 2 feels fantastic in your hands and sports a robust, stylish-looking profile.

The somewhat muted dark/light grey color combination contrasts nicely with the bold, vibrant LED indicators.

Front Panel

The left-hand side contains 2 combo TRS/XLR inputs.

Use these to record your electric/acoustic guitar, microphone, synthesizer, etc. via XLR or TRS cable.

This is a huge added benefit for those who may want to rap or sing, but it also gives you the flexibility of recording yourself playing guitar simultaneously with an additional mic.

Just having that extra input is incredibly convenient. I typically keep Input 1 for all recording/rap/voiceover, and Input 2 I swap out depending on what I need to record: A bass, guitar, synth, etc.

Next to that is the gain knob with 2 small LED lights next to it.

These will help you monitor your voice in real time to prevent clipping.

Next to that is the vintage button; a pretty neat feature that allows you to call an emulated UA vintage 610 tube preamp to your voice or instrument.

More on that later.

48V Phantom Power

Before pressing the record button, don’t forget that condenser microphones need phantom power to achieve standard loudness.

This button is next to the big volume potentiometer on the left.

In addition to that,

the Volt 2 allows for direct no latency monitoring, and there are separate volume controls for the speaker and headphone outputs.

I tested this and it works like a charm.

I typically don’t like monitoring myself because of personal reasons (LOL), but here I can without much of an issue because it truly does monitor in real-time.

Even several milliseconds of delay is a nightmare and I know most folks reading this can attest to that.

Not so with the Volt 2.

Back panel

Universal Audio Volt 2 ReviewUniversal Audio Volt 2 ReviewUniversal Audio Volt 2 Review

If you have a keyboard controller with MIDI, there are 2 5-pin MIDI ports on the back in addition to the USB Type-C jack, 5V DC power jack, and balanced TRS outputs. I’m currently using them with my Yamaha HS7s.

UA didn’t include a power brick in the box, but you won’t need one. Just plug it into your PC via USB and away you go.

Recording Quality

Simply put, I love this interface, and recording with it is a breeze.

These are ultra-clean, professional-sounding preamps and for the price, how could you go wrong?

Thanks to its built-in tube emulation circuitry, you’re essentially getting a vintage sound used to record artists like Ray Charles and Van Halen.

Pretty neat.

What’s even better?

Universal Audio took the liberty of bundling a whole heap of music production tools to help you get going.

Just flip open the box and you’ll see a URL.

Go to www.uaudio.com/volt2/start, and you’ll be asked to register your device and create an account.

Follow the steps, download the firmware via some prompts, and you’ll reach a page that looks something like this:

Now click Volt Software and take a look at all of the cool effects and processors:

  • Ableton Live Lite (music production DAW)
  • Softube Marshall Plexi Classic Amp (guitar amp sim)
  • Softube Time & Tone Bundle (mixing effects processors)
  • Celemony Melodyne Essential (pitch correction)
  • Relab LX480 Essentials (classic studio reverb)
  • Plugin Alliance Ampeg SVT-VR Classic (bass amp sim)
  • Brainworx bx_tuner (guitar/bass tuner)
  • Brainworx bx_masterdesk Classic (mastering processor)
  • UJAM Virtual Drummer DEEP (virtual drum instrument)
  • Virtual Bassist DANDY (virtual bass instrument)
  • Spitfire LABS (virtual instrument)

Vintage Mode

Here you can listen to the subtle (but noticeable) difference. I do think Vintage sounds pretty fantastic and gives your voice that extra edge.

These are both raw recordings with no EQ or effects applied. Gain is set to around 75% and I was using Reaper/Audacity.

Vintage On

Vintage Off

Recording Guitar

I don’t plan on using this microphone for any serious guitar work, but I thought it would be interesting to show the effects of EQ before and after.

Here I was just noodling around with some chords and came up with what I call “Ballad For The Scatterbrained.”

Hope you enjoy it!

Here’s a video I recorded of the sound quality:


Sound Quality

Universal Audio Volt 2 Review

I listened to over 30 hours of music with the Volt 2 out of the 1/4″ jack paired with a HIFIMAN Edition XS and in short, it was time well spent.

A large portion of those hours was spent listening to the entire discographies of Aphex Twin, Björk and Pink Floyd.

The rest you can access from the playlist linked above.

To my ears, the Volt 2 isn’t entirely neutral, but I don’t mind it much. It sounds pretty excellent and I have no complaints.

Thanks to its balanced TRS outputs, you can connect these to studio monitors as well and they’ll sound great out of this unit.

Headphone Tests

I recently got a comment (Shoutout Bruno) about whether or not the Volt 2 can drive a K702, so I thought I’d go over some common headphones I have here and help clarify just how much power the Volt 2 has, how much headroom you’re afforded, etc.

AKG K702

Despite the K702’s incredibly low Sensitivity (91dB) and inefficient nature, the Volt 2 provides more than enough power here as I don’t need to go past 9 or 10 o’clock on the dial for any reason.


HIFIMAN HE400se Review

Like the K702, the 400se is also rather inefficient (also 91dB) so you’ll still be around 9 or 10 o’clock on the dial with heaps of headroom to spare. The 400se has a lower impedance (25 Ohm) than the K702 (62 Ohm), so it may be slightly easier to drive though from my tests it was kind of still awash.

Sennheiser HD600

Despite having a much higher impedance at 300 Ohm, the HD600 isn’t terribly inefficient (97dB) so it’s actually easier to drive with a Volt 2 than both the 400se and K702. This is why I typically place more emphasis on the Sensitivity rating, but both metrics are still important.

With the Sennys, you’ll be at around 9 o’clock or less.

If you have any more requests, drop a comment below!

Before we give a final verdict, let’s recap what I liked and disliked:

What I liked:

  • Super simple setup. Plug and play allows you to start recording right away.
  • The no latency feature works as intended with no delay whatsoever.
  • The microphone preamps are excellent.
  • 24-bit/192kHz audio conversion covers any and all recording situations you may encounter.
  • The vintage mode gives an extra edge to vocals and makes my voice sound more professional (it’s anything but, LOL).
  • The understated look + rugged all-metal construction feels fabulous in your hands and you can tell it’s a rock-solid unit.
  • Can be used remotely with iPhone or iPad. Just snag an external Volt power supply and an Apple lightning adapter. If you have an iPad Pro, simply use its Type-C connection.
  • Access to a 30-day trial of UAD Spark Plug-Ins On Mac
  • The extra software bundle mentioned earlier is a great added value.
  • Sounds great paired with headphones and speakers/monitors.

What I disliked:

  • Nothing. If anything changes as I use it for my projects, I will update this article.

Final Verdict

Universal Audio Volt 2 Review

This is a perfectly priced unit and provides more value than a Focusrite Scarlett 2i2.

As much as I love that line of products, I think Universal Audio has a more valuable interface here and I can’t recommend it enough.

If you’re an aspiring musician, beatmaker, producer, rapper, singer, etc., you need an Audio Interface.

It’s the centralized hub for everything you do in the studio, and the Volt 2 has all your bases covered for a more than affordable price + it has loads of power.

Update: It also just won an award which I think is well-deserved. This is a fantastic product.

I found your review of the Universal Audio Volt 2 to be quite accurate and helpful. I did have a few questions though. In your opinion, what is the best way to get started with using the Volt 2? Also, what are some of the most important things to keep in mind when using this piece of equipment? Thank you for your time!

Stuart Charles Black November 23, 2022 - 2:44 pm

Hey man! Thank you for your comment and nice words. What are you doing specifically? Rapping? Vocals? Guitar? Let me know and I can guide you in the right direction.

As for your other question, here are some important things to keep in mind:

1. With condensers, always remember to push the 48V button on the interface. This may seem silly, but you’d be surprised how many negative reviews I’ve read over the years that said X product was faulty or bad, or their condenser mic didn’t work when in reality they just didn’t really understand how interfaces/line level signal works.
2. With dynamic mics like the Shure SM57, absolutely NEVER turn on phantom power because they don’t need it. You can just plug it into the front and record it as normal.
3. Plan to use studio monitors for mixing (in addition to headphones), but remember that you’ll need a couple of balanced TRS to TRS cables or TRS to XLR (one for each monitor).

Those are the things that come to mind first. An audio interface is truly an amazing thing to have in the studio and I’m super glad to have one back after having to sell my old 2i2.

In any event, I look forward to hearing from you again!

Awsome review! Do you think it can drive alone the K702?

Stuart Charles Black May 18, 2024 - 10:51 pm


Thanks for the love! Absolutely. I actually just wrote another section about a few headphones and how they fare with the Volt so thanks for the question. The Volt 2 has heaps of power and easily drives the K702 with plenty of headroom to spare.
