If you’re still new to the brand, let me introduce you to a soon-to-be close friend of a fledgling content creator. Meet PreSonus, a leader in the recording industry since 1995. With products ranging from microphone preamps and control surfaceare from digital mixer and studio monitor arrive Powerful software, PreSonus is a leader in developing audio technology with consumer accessibility. And, the company caught the attention of Fender Instrument Corporation, who bringing PreSonus into the Fender family in November 2021. Not a small partner!

If you read our reviews of PreSonus Studio 26c or USB Revelator Microphone or you happen to be familiar with the brand, you’ll know we’re not kidding when we say that PreSonus has a penchant for accessibility to the creative process. Whether you’re looking to start a home studio, set up streaming, or if you’re looking for a digital mixer for your church or club, PreSonus not only has the right tool for the job, they give you the software support and video tutorials you need to be successful. For example, the Revelator io24 we’re reviewing comes with PreSonus’ Studio One 5: Artist Edition ($99 value) or a subscription to the StudioOne Sphere service – both with digital audio workstation experiences ( DAW) powerful. Along with access to the DAW, PreSonus packs a curated set of plug-ins to enhance your recording experience right out of the box.

All of this doesn’t even affect the plug-and-play experience with Revelation io24. Follow in their footsteps USB-based desktop condenser mic with a similar name, io24 used the Universal Control. Serving as PreSonus’ driver suite toolbox, Universal Control can be used to modify cross-device settings and update firmware, but its crowning function is its place as commands hub for your audio mixing needs. From the Universal Control, users have access to eight presets including six adjustable plug-ins as well as six user-created banks for storing settings, tuned to the user’s voice.


Here, the real utility of the Revelator io24 really shines (and where I’ve made no secret of hoping PreSonus continues to use their audio interfaces). In addition to modifying effects, Universal Control provides Virtual Outputs for users to send their sounds to. This allows users to set up multi-channel mixes without the need for a mixing console. It’s limited to three sources outside of the microphone, though, but it’s enough to mix background music, Discord calls, and in-game audio all from the comfort of a single piece of software.


Since we’ve talked a lot about the software that drives the interface, let’s take a moment to talk about the design and layout of the device itself. On the 7-inch (180mm) wide side, there are two XLR (balanced) / ¼” TS (unbalanced) combo jacks powered by PreSonus’ legendary XMAX-L microphone preamps. The front panel also houses a series of buttons for selecting channels and effects, a mute button for connecting the Main Out speakers, a knob for controlling settings, and a small color LCD that provides real-time signal monitoring. real time. A simple layout, but quite intuitive if you don’t mind pressing some buttons!

Speaking of push buttons, we noticed a few oddities that caught our attention. At the time of writing this review, settings for modifying what each control button do do not exist. This is a bit flawed, especially when it comes to both the physical mute button and the Hotkey settings. The mute button is limited to only muting the Main Out lines, and as far as I can tell, the HotKey setting can only be controlled by clicking the button in the software. Neither of them have the option to change the source they control or add keybinding to. They are fixable in future software or firmware updates, but for now, their use is very limited.

Before we wrap things up, let me show you a little bit about what PreSonus allows you to do with this simple yet powerful tool.


With software-based customization layers and multi-channel mixing, the Revelator io24 serves as the master layer of what a modern audio interface should be. Priced at $199.95 USD, the bundled software suite and supporting plugins offer incredible value, making this audio input device a one-stop shop for digital content creation.. .

While the Universal Control software provides a good platform for modifying effects, the Revelator io24’s ability to process those effects in real time is limited to 48 kHz or less. While this isn’t too bad for most content creation, live streaming, or voice chat apps at the moment, it puts a lower ceiling on the sound quality you can get. There are alternatives to this; Users can set up analog effects in the included StudioOne Artist digital audio workstation, routing output audio from the DAW to Universal Control, circumventing this limitation.


At the end of the day, the pro audio powerhouse offered an audio interface that combined classic PreSonus microphone preamps with their Revelator digital effects and controls via the Multi Control. The marriage is harmonious and the outcome is simply stunning. The software that works in conjunction with the video library that PreSonus provides could just make a perfect platform for users to learn the ways of the audio wizard and make some real magic happen.
