Seems to be high enough quality except for the fact that I can't actually configure it from the software side via the universal control app. It is wanting me to "update" my firmware to v2.21 before I can use it. It's worth noting that this shipped with v2.22 - They shipped out a version they can't actually support in software. Most of the config I need I can access from the DAW itself, and running it on OSX really alleviates the need for anything too special as everything is baked in, so this isn't a deal breaker, it's just strange.Also, I have to reboot the device itself if I reboot my machine for any reason, often with plugging/unplugging the interface to get it to show up. This happens with plenty of other USB-C to USB-A cables, and it happens regardless of port I use.If you need help, then good luck actually getting any support from presonus! There's literally no way to contact support at this point in time, maybe you will be lucky enough to have your forum post or your question actually show up. Consider this a community supported device at best, so be comfortable with digging through forums.That being said - It's a high quality interface. It works very well with logic. It works with CV tools and Silent Way. It does everything I want it to do so far. OSX means that extra config tools are largely unneeded (I think, there's no way to actually see what the "Universal" tool lets you set on this). I can record from any source I have, and I can route audio the way I wanted. Reliability has been rock solid outside of the above "reboot" issue. This is a pretty simple interface, and that isn't a bad thing.Most importantly, this is one of the few DC coupled interfaces out there. If that's something that is important to you, and this has the appropriate amount of IO for your needs, this is a great option.--- UPDATE Aug 16 2019 ---Ok, I'm dropping a star here. There's no way to get direct monitoring in stereo that I can see, which is a pretty significant oversight. Software configuration of this is still nonexistent. I've been seeing strange behavior with the audio rate not remaining consistent. Since there hasn't been any support to talk to, I went ahead and "updated" the firmware (i.e. installed the version actually available, which is one version older than what I have) since that was required for the universal config tool. The good news is that i could use the "universal configuration" utility after that "upgrade", the bad news is that it doesn't do a damned thing I need it to, and there was no way to know this until I was able to run it, since it isn't documented. Let's hope the firmware update didn't break something.Support is still practically nonexistent, although I can apparently open a ticket (finally) - I'm skeptical that it will be answered, I'll update if it is - otherwise, assume it hasn't been. Documentation is very limited compared to other interfaces - Over half of it is dedicated to the recording software that I'll never use, and details on the hardware are really lacking. If this wasn't useful for control voltages, I'd have given up on it by now - Shame it's more useful for CVs than for audio. Guess I'll be dedicating this to CVs and mono inputs.Guess there's a reason this is one of the less expensive DC coupled interfaces.-- FURTHER UPDATE 10/06/2019 --I was able to open a ticket regarding stereo monitoring after a lot of trouble with their interface, they requested a dump of my OS config which was totally unneeded and then followed up a day later with what was effectively "what was your question again?" (I'll note that my question was if it was possible to do direct monitoring in stereo and was quite clear), and I kept trying to log into the system to reply, but it wouldn't let me. This ticket auto-closed in like a day. Support is a joke.-- FINAL UPDATE 12/14/2020 --It's been a year and a half. "Universal control" still doesn't support the firmware that shipped on the device. There have been no further updates. I never got a good answer on any of my questions. This product apparently was abandoned upon shipping. I guess they don't care about anything other than their higher-end products, if they even care about those. No way I'll ever know if they care, because there's no way I'd ever purchase anything higher end from them based on this experience.—- FINAL FINAL UPDATE —-Yeah, I don’t know why I dug this back out instead of getting another interface - I just needed some more audio ins and had this laying around. Well, when I thought things couldn’t get worse — THEY DID. I’ve been troubleshooting my desktop all day because it’s freezing on boot, and just now found the culprit. Can you guess what it is, since I’m writing it in this review? It’s specifically the universal control software that is breaking things. I should have never updated it, or even installed it in the first place since it doesn’t do anything useful. And honestly, I should have just set this interface on fire a long time ago. I’m definitely done with it — and presonus — for good. The only reason I’m not setting it in fire tonight is because setting electronics on fire isn’t exactly great for anyone’s health or air quality. So off to the electronics recycler it goes.Good for podcastingI’ve dropped this multiple times from decent heights with no damage(accidentally lol). ImpressiveReally like the sound and functions of this interface! Brings alot of quality to my work.I hooked a Shure SM7B to this with a CloudLifter CL-1 and the sound quality is better than I expected it to be at this price point. I had a 24c but upgraded to the 68c. The extra ins and outs are very handy. The 68c also has significantly better LED meters than the 24c. The only other major difference is that the 24c is portable and does not require a dedicated power source. The 68c must be plugged in to an outlet. On the plus side, the extra power does give you a few extra decibels.It comes with a license for Studio One, which is a pleasure to work with. I haven't tried it with a control surface yet, but that may be a not-so-distant future addition to my setup. If you're looking for something good for streaming or for recording music, this is a very solid choice.I waited 6 years before finally buying one of these audio preamps. I kept tryin to convince myself that USB headset devices would "be better next year"... Just stop.Stop playing the games with overpromissed marketing and just buy one of these for real audio fidelity on PCI'm a virtual trainer by profession and when I show up with my audio Technica AT2020 with my mx40s people are blown away by the quality in all virtual collaboration tools I use.I know I've sold a couple of these to executives already just by the experience they received.So happy with this product.I like the presonus 24c.the four meters are great, two for the inputs, and two for the mains. The mains are useful when using the headphone jack. The inputs are useful for quick gain adjustments.The idea of a single USB-C port for both power and data is great. But in practice, I found it somewhat wanting. With a laptop, it's actually very nice as it's a single cable for both, and the sound stays very clean.But for connecting to a tablet, it's less useful. iPads don't send out enough power through the lightning port or the new usb-c port to power up the 24c. So, you need some kind of hub in between that handles both powering and data pass-through to the iPad. I don't have any such hubs, but even if I bought one, it's one more thing to carry. If I have to run off a usb battery, then that's 4 things to carry, not including the mic and headphones.So, I would have preferred split ports with the option to run data and power through a single port, or the option to run data through one port and power through another. A simple toggle switch to determine which is preferred.A lot of audio interfaces in the same price range do this. Those devices use older USB interfaces, and frankly, for those devices, the single-port-for-both-power-and-data options is not good, nowhere near the cleanliness of the presonus. But still, I would prefer that choice.I also with the xlr inputs were in the back and the headphone jack was in the front. Seems like most interfaces have the xlr inputs in the front. Not something I prefer, but oh well.Though this may be a lot to ask for such a cost effective device, it would have been nice to have a couple of HPF options and a couple of limiter options. But for the price, maybe that's pushing the desire a bit. I currently have a sound devices 302 in front of the presonus to handle HPF and limiter duties. A rather expensive way to go, but it works well.All in all, a great little device. clean sound, easy to use potentiometers, simple button for phantom powering, indicator for USB power on. For under $200, damn impressive.I originally submitted a review of this device slating the manufacturer.However, I am going to update the review...This usb interface is actually pretty ok.Maybe It felt shy or something the first time I tested it, but I have tested it again both on an sm7b (with Cloud lifter) and an SE X1SThe Preamps- have a very clean -deep soundThe Gain is 50db on this unit, the Focusrite Scarlett range boast 56db so slightly better gain and again a different sound.The 26c report 80db which, for sm7b users, may be the better option.Can't fault this device,Apologies for the initial poor first review ;-)Update: 19th January 2019SO I upgraded to the 68C - Oh My Days!!Absolute brilliance.Beautiful set of Pre-ampsAll +65 Dbs - It's like comparing a focus and a jaguar, no comparison, these pre-amps drive my mics powerfully and no noticeable mic noise at all.The headphone amp is super powerful. and brings a real lively tone to my musicThe USB Interface works perfectly, I had issues with getting 'stereo' sound when using the 26c but the drivers for the 68c has sorted everything without complication for Windows 10 users.So I can run webinars, record videos, run FB Lives etc and have no concerns with sound at all.Using Adobe Audience is wonderful and mapping the channels is really easy.Presonus state the USB quality is 24bit @ 192KHz using USB C - I am getting 32 Bit Recording quality from this unit (it actually states 32bit @ 192Khz) - What more can I ask for???Solid 5 stars for the 68c - It takes the Presonus into a completely different leagueIt drives the Shure sm7b Dynamic mic wonderfully. It's the best sound I have achieved to date and do not need a Cloudlifter at all, as the levels are perfect for my voice.I may consider re-enforcing with another pre-amp, just to get more headroom, but I do not have to rush, it can do the job effortlessly as is.If you are considering a solid, Audio Interface to drive ANY mic, and have brilliant sound quality for a very competitive price, with USB C delivering 32Bit quality recording @ 192KHz, then look no further than the presonus 68c!I initially bought the 24c version of this. The unit is well built, well packed and a great price, the free software is great and a step about audacity.I had to return though - why? The key as to which you buy will need to really depend on your microphone. I am using the Rode NT2 and the 24c is just woefully underpowered to make that mic work. At Max gain I was only just getting the mic to clip, so the headroom to play with the settings on the unit were virtually nil. Using some software gain helped, but it’s not the solution. As my mic needs about 50hz to activate and this unit maxes out at 50 (and in some tests nearer 44) it just did not work for me. Shame, becaise for a simple cheap 2 input unit, is nice.Swapped then for a 68c. Which works perfectly. A smoother sound due to the higher spec amps and with a gain that goes to 65 much more room to play. The unit build is same but it’s larger and the signal indicators on the front seem to work better as well. I managed to get a warehouse deal, which was even better and not then a huge difference in cost for the performance. Note you have to plug in the 68, which might also account for the ability to power better and the 24 is usb powered.My main challenge with the 68 was it came stinking of cigarette smoke. Pretty sure this was the driver and not the warehouse but had to leave the packaging outside for a day to get rid of the smell.I bought this to replace a rather flaky and cheap Berhinger audio interface which I had regretted purchasing for some time. I have not been disappointed with this. Great build quality, fantastic sound, and an impressive set of features. It also has a nice bundle of sofware included from the likes of iZotope, UJAM, Arturia, the brilliant Klanghelm, Presonus' own Studio One Artist (already have SDRR and Studio One, so I guess I'll be selling some software on KvR) - most being "lite" versions, but still nice. Back to the interface... I can't stress enough what an improvement this has been to cheaper alternatives I've tried. Very happy.Despite careful installation, this Presonus was unreliable in operation.I bought it to remove latency delays between key presses on my Yamaha MOXF8 when triggering a VST (Garritan CFX).The latency anomalies were defiintely removed after the Presonus was used and audio was also crystal clear. However, when I went to launch You Tube at the same time as the VST, the Presonus would dump all audio context, rendering the whole process useless.Moreover, the Presonus only came with a small USB C tail lead, which meant I needed to place the Presonus on top of the PC to allow it to physically connect. This was really inconvenient too.I liked the Presonus (when it worked) but with so many niggles I sent it back for a refund. I now use a Focusrite 2i2 which is totally reliable and has a much longer USB C lead to connect it up with, thus allowing more convenient placement of the audio interface on my desk.Si bien la interfaz tiene una excelente calidad, pues no hay deformación en frecuencia en ganancias por debajo del volumen máximo, el piso de ruido es mínimo, es plug and play y funciona con el ipad (si lo alimentas de forma externa) creo que su valor agregado radica en la licencia completa de Studio one Artist que incluye de forma gratuita. He utilizado otros DAWs como Reaper, Ableton Live y un poco de Pro Tools (la realidad es que todos hacen casi lo mismo) y sinceramente siento que el flujo de trabajo es mucho más sencillo e intuitivo en Studio One. Además si cuentas con un ipad conectada en la misma red (y por supuesto con la app de presonus) puedes utilizarla para controlar los FX, ganancias, nivel de los faders etc, lo cual facilita el proceso de masterización.PROS:1- Excelente respuesta en frecuencia de las entradas a volumen moderado (en volumen máximo hay una distorsión en las frecuencias bajas)2- El ruido de los preamplificadores es bastante bajo (no encontré diferencia perceptible contra una focusrite)3- Cuenta con “monitorización directa” para evitar latencias (que por cierto encontré que son muy bajas) NOTA: he visto en algunos foros que la monitorización es monoaural, sin embargo yo escucho la entrada en ambos canales4- La respuesta en frecuencia de la salida principal es totalmente plana (por lo que tus monitores van a sonar exactamente como deben sonar)5- Tiene indicador de nivel tanto para la entrada como salida, sin embargo tiene un contra (ver más abajo)6- Puedes modificar la mezcla del monitor y de los tracks reproducidos en la PC7- La construcción se siente bastante sólida8- Funciona en iPad9- Tiene MIDI y funciona impecable (probado con una batería ALESIS)CONTRAS:1- La ganancia de entrada es un poco más baja de lo normal (lo cual no es problema puesto que la puedes aumentar el post producción)2- Los indicadores de nivel de entrada y salida apenas y se mueven (no los puedes usar como referencia para configurar correctamente la ganancia con el potenciómetro, tienes que basarte en el DAW)3- Si usas audífonos de baja impedancia tienes una pequeña distorsión en frecuencia (Para esta interfaz es mejor utilizar referencias de alta impedancia)POSDATA:Hay bastantes videotutoriales sobre Studio One en Youtube (si haz manejado otro DAW sinceramente ya sabes de antemano usar este). Sin embargo, si no entiendes bien el inglés (Ponte a estudiar porque las mejoras referencias están en ese idioma) y eres totalmente nuevo en el mundo de la producción de audio, busca el “curso oficial de studio one” de GusLozadaTV (encargado de presonus en América latina) está buenísimo y super completo.
