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, please search on Thingiverse or PrusaPrints (I cannot link them directly here)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 hard way that my hub is apparently garbage, which is 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, below is my original review. I changed my review from 1 stars to 5 stars. The main reason I gave it 1 start initially is that there was an issue on the outputs (see below) but it 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.----------------------------------------On paper this unit is perfect for me. However when I received it and gave it a try I immediately noticed a pulsing noise on the headphone output even when nothing was playing from my computer (see attached video to hear what I’m referring to). I thought the unit was DOA so I sent it back and got a replacement shipped. The second unit had the identical problem, so I opened a support ticket with PreSonus and started looking around online for similar reports. Though I did not find very many reports, which I partially chalk up to it only being on the market for a few months, I did find enough reports of the exact same issue that I think people should be wary about buying this right now. If/when it gets resolved, I will update this review accordingly.I cannot link to them here but there is a thread discussing it on the PreSonus forums (topic # 46094, “Noise coming from Revelator io24. Exchange for another unit also generates same noise :(“), and on the r/presonus subreddit (title “Revelator io24 - noisy headphone output?”), and a few comments under reviews on YouTube.PreSonus was very responsive to the ticket I opened, but after exhausting all troubleshooting options they didn’t have a solution and just said their development team will look into it and to hang tight.OK, I take it all back... (see original review archived below).The good folks at PreSonus contacted me directly. They humbly admitted that the headphone and output noise issue was a grounding problem and promptly replaced my unit after receiving the return. I can say after hours of testing they have 100% solved the problem.As I mentioned, I wanted to love this product because of its built-in DSP functionality and fat channel. Now I can say that I do!I expected the headphone amp to still have a little bit of white noise at full volume (don't they all?), but it is WICKED quiet now. The difference with the new fix is night and day. The inputs also have more life and 'air' to them. That could be because previously the white noise was masking the high-end, but to my ears solving the grounding issue may have also effected overall performance..?As with all PreSonus software, the DSP mixer is clearly laid out and a breeze to use. For the uninitiated, it would be advised to briefly read the manual. My favorite part is that it seamlessly integrates into their Studio One software (included). Without having to leave the program, you can dial up the IO24's fat channel. My favorite parts are its DSP compressors: standard, tube emulated, or Class-A FET.For this price of $200, the Revelator IO24 is an incredible value. It has functionality not seen in other interfaces at this price. It can be used for high quality recording as well as live streaming with its super easy loop-back functionality. Speaking of, one reason I purchased this is to collaborate remotely writing tunes with far-away friends. With 'original audio' turned on in zoom, this thing is an amazing tool.Although the original defects should not have been brought to the market in the first place, a big thanks to PreSonus to listening to its customers. Companies make mistakes and kudos to them for owning up to them, then quickly offering a fix.---------------------------------------[original review 20 Oct 2021]I wanted so much to love this new product - its built-in DSP mixer with fat channel and reverb was just what I was looking for. But I'm in disbelief that PreSonus released this thing with such a noisy headphone amp AND noisy line outs. Many others have complained about this, but it seems PreSonus is doing nothing about it thus far. I would give this thing 1 star if I wasn't such a PreSonus fan - I write reviews for tapeop magazine and after my rave review of Studio One, am now a convert of both their software and hardware.As others have stated, lower ohm headphones have slightly less of a noise problem, but even with my 33ohm Grado SR80s, there's a distracting pulsing noise at low volumes and significant dirty white noise at medium to high volumes. Worse still, when I connected my PreSonus eris E5 monitors to its outputs (told 'ya I was a fan) with the exact balanced cables I use with my other interfaces, the dirty white noise was still there.This noise doesn't get recorded, but the problem is, it's completely disorienting. Because the io24's noise-floor is so high, it will mask any faulty cables, mic noise, etc., potentially ruining hours of work because you couldn't detect it.My suspicion is that PresSonus had to make a lot of compromises under the hood to make this bus powered. Just think: phantom power, hardware DSP, headphone driver, etc... all from a lil' old USB port port. (Yes, it's USB C, but it comes with a USB C to USB A cable. Even when connected via USB C to C, the exact same problems plague it). As a compromise, I could live with an outboard power adapter over the host of these awful problems... OR they could have done what Audient does with their beautiful sounding id14mk2: tell their customers that if you DO connect USB C to A, the performance of the headphone amp is diminished. The io24 clearly is not taking advantage of the higher power delivery of USB C.I do radio shows from my vocal booth every day. I recently purchased the Presonus revelator io24 because of the compressor and small size. It seems to be working quite well but if I could improve it I would move all of the inputs and outputs to the back to help clean up my desktop. I would also add a power button to the front (it currently doesn't have one at all) so it can be turned off instead of having to unplug it from my laptop every day.The Universal Control app on the laptop makes setup and adjustments easy. It's been helping my shows sound better.Audio Engineer here. Been looking for a budget audio interface with real-time processing, and came across this. I am using an SE7 MIcrophone to chat with my friends while playing games. I was using a headset for this previously and was not satisfied with the quality, hence adding a few studio gears into my gaming setup. the great thing about this was it allows you to have up to 3 different mixes and output routing to different software. I love this audio interface.!A great tool for recording demos and tutorials, super easy use for video calling and all-round great product.It's not the prettiest thing in the world but it blows all interfaces in this price range out of the water.You have loopback, made easiest by far than any other company.Decent mic/line inputsOnboard DSP effects for treating your voice.3 mode volume for both main output, headphone output and mic/monitor blend.Super 6 starsWas too cumbersome to set up and the software works fine but the power itself is very limited when you start using better mics, a headache I had to get rid of.Auch wenn man für das Shure SM7B besser noch einen FetHead Adapter dazu bestellt um den Mixer nicht bis zum Anschlag von 60db hochzudrehen (verstärkt eventuelle elektronische Nebengeräusche), kann man das Mikrofon dennoch anschließen und loslegen.Die Software läuft störungsfrei, auch unter dem aktuellen macOS Monterey. Firmware Updates gibt es auch.Das Bedienkonzept was eine iPad-App mit einschließt über die man alle Funktionen und Presets ebenso steuern kann, sollte man nicht unterschätzen. Ändert sich die Bedienoberfläche, ändert sich die App und statt eines Hardware-Mischpultes hat man eine ständig aktualisierte Oberfläche.Das die Hardware selbst alle Effekte, Presets und Einstellungen intern speichert, sollte man besonders bei wechselnden Computern als Vorteil sehen.Fazit:Es kommt selten vor, dass ein Mixer so durchdacht ist und auch mit macOS fehlerfrei funktioniert. Die Effekte sind etwas limitiert aber ausreichend. Die Remote-Steuerung über ein iPad sehr nützlich, wenn man die Maus woanders braucht. Die vorn-liegenden Anschlüsse nicht sehr ergonomisch, aber verkraftbar.Rundherum zufrieden, Weil dieses Interface eine gute Tonqualität mit hervorragenden Effekten abliefert. Die Software ist stimmig. Ein günstiges Interface für schmal budgetierte Tonproduktionen. Ich kann es weiter empfehlen.I'm doing VO and while this is amazing and 100% goes toe to toe with the likes of GoXLR. the power of the DSP is amazing. But I opted for the Elgato Wave XLR, I don't stream. so the Latency of the VST's isn't too important to me. Me as a highly visual person. could not stand how the Presonus interface sat on my desk. like most audio interfaces, the XLR cable was sticking out on the front it was so awkward to place it. while the WAVE XLR has the XLR cable behind, I love the big knob, I love the simplicity of it even though I know it's an inferior product in comparison. I felt the WAVE XLR had a better Physical UX and took up less space on my desk, and since my work station is in my room. the lights of the Presonus also really bothered me which I had to resort to covering it up every night....I really do recommend this product if how it sits on your desk doesn't bother you.
