Revelator Processing Power Meets the USB Interface

Around Sweetwater, PreSonus audio interfaces have a reputation for delivering premium audio quality at an accessible price. That distinction rings true with Revelator io24. It’s a highly portable bus-powered interface with serious horsepower under the hood. Revelator benefits from the same DSP found in the acclaimed Studio Live III Series mixers, which lets you add effects to your signal without external processing! Of course, you can’t apply DSP without a solid signal. Revelator io24 has a pair of super-clean XMAX-L microphone preamps with tons of headroom. Other professional features include MIDI I/O, at-a-glance metering, and optional wireless control with a smartphone or tablet. Optimized for streaming, podcasts, and music production, Revelator io24 has more than enough power and flexibility to take your sound to new levels.

Premium vocal processing onboard

The Revelator io24 isn’t just a streamer’s interface! Podcasters and recording musicians at Sweetwater find the flexible onboard vocal processing to be quite valuable. The professional sound designers at PreSonus included expertly engineered presets to ensure you'll sound your best, and you can add effects to any channel at the touch of a button. You're sure to find the perfect preset from simple EQ and compression to broad and luscious reverbs. For more extensive control over your effects, download the free UC Surface app for iOS and Android. From there, you can adjust all effects parameters wirelessly from your smartphone or tablet.

Features fit for streamers

If you’re streaming to Facebook Gaming, Twitch, or YouTube, you’ll need an interface that can hold its own. The Revelator io24 is tailor-made for the job, allowing you to capture the sound from your mics and computer with ease. How easy is it? Just engage the Stream Mix feature when you’re ready to go live. Revelator io24 will automatically set up a stereo mix complete with two stereo loopback channels and effects with a single click. In addition, you can set up a custom mix for every input and output channel to achieve the sound that you desire. When we tested the Revelator io24 at Sweetwater, we appreciated the independent reverb bus that adds a final polish to your stream’s sound.

This unit is frankly perfect for me and would make a very solid and versatile addition to just about any audio setup. If you've got a basic USB audio interface like the Focusrite Scarlett Solo, this is a fantastic upgrade. If you're considering the GoXLR, especially the mini (as I was), you should consider this device instead. I'll be comparing them a bit below as I speak to a few of the features that are most relevant to me.

- Cross Platform: This unit is completely standards compliant, which means it works on both Windows and macOS (and I suspect Linux as well, though I haven't tested it myself yet; I have tested both Windows 10 and macOS Big Sur and Monterey, including with M1 Apple Silicon). The GoXLR relies on their proprietary software so you're out of luck if you use anything other than Windows.

- Integrated DSP (digital signal processing): This allows you to add a filter, gate, compressor, equalizer and limiter to the inputs that run on the device itself as well as a few voice effects (Doubler, Vocoder, Ring Modulator, Comb Filter, Detuner, Delay, and Reverb). This means you get all those DSP features without having to run specialized software and waste processing time on my computer (no VST plugins or VoiceMeeter!). This fact is probably the single best feature. The GoXLR has an equalizer, compressor, gate, and the full GoXLR (not the mini) has similar voice effects (Reverb, echo, pitch shifting, gender (formant shifting), megaphone, robot, hardtune, and sampler) but both it and the Mini do not have a filter or limiter from what I can tell.

- Virtual Routing and Mixes: Allows you to route different audio streams separately without any additional hardware. This is similar to what the GoXLR does. I haven't tested this extensively but it is very similar so I think they're about comparable.

If you'd like to mount it under your desk like in the images I've attached to this review, find a friend with a 3D printer and checkout my design on Thingiverse (thing 5034259) or on PrusaPrints ("Under Desk Mounting Bracket for PreSonus Revelator io24")

My only word of warning is make sure you're plugging this directly into your computer or if you cannot, into a very high quality hub (I discovered the latter the hard way, unrelated to the issues below). As with many other audio devices, especially those with DSP type features, if the unit is not getting quality power you will have issues.

----------------------------------------

Note:

The above is my updated review. I changed my review from 1 star to 5 stars. The main reason I gave it 1 star initially is that there was an issue on the outputs, as mentioned by a few other reviews here and elsewhere. That has now been completely resolved; the cause was a bad batch of units. They shipped me a replacement unit which I have been using for about a week now and I can confirm that the issue is completely gone. If anyone else has this issue you just need to contact PreSonus support to get a replacement. In my opinion, PreSonus has done a great job of resolving this issue. I am satisfied with my care.

Bought this interface to go with my newly upgraded AT2020, it's so easy to control and tweak to my usage! Sound quality go brr!

I've always used Presonus audio interfaces,, this one is exactly what I've been looking for because it makes streaming on Twitch much easier. I have to admit tho the routing of outputs had me stumped but was able to get help from Phil Potts (my sales engineer) and technical support to help me with this. Thanks Sweetwater

This is an excellent audio interface. It simply works, plug and play connectivity and recording with my surface laptop and samsung s10. According to the manual also works with ios devices with the Apple camera adaptor. I initially had purchased the much cheaper behringer uphoria umc22 and was tremendously disappointed. With the on board dsp it is definitely the best bang for you buck at this price point. Although this product seems to be mainly marketed towards streamers, it is an excellent choice for guitars, basses, keyboards, mics, ect. Highly recommended! Big thanks to Matt Stockburger at sweetwater for recommending this product!

As a guitarist, I recently purchased an AXE I/O to replace my io24. I ended up returnimg the Axe and kept my Revelator io24; which led me to this review. The io24 gives you so much freedom and creativity. The preamp is great. As a musician, streamer, and a gamer, this interface does it all! The universal controller software for this interface is heaven sent. This product started my presonus fandom for sure. Would definitely recommend over any other interface in this price point. Believe me, I've owned them all.

Sweetwater and PreSonus go way back, and that makes a lot of sense. Like Sweetwater, PreSonus is largely staffed by active musicians, songwriters, live sound techs, and engineers, and like Sweetwater, their culture shows up in everything they do. Early on, PreSonus broke ground by offering super-affordable audio interfaces that brought quality recording to home studio engineers everywhere. In the following years, we've been with them as they introduced a powerful, artist-friendly DAW, groundbreaking digital mixers, and more - all products we at Sweetwater use ourselves. One thing that's never changed, even as PreSonus has branched out into new territory, is that they've always done everything possible to provide you with the best value, and we're proud to stand by their products.
