That is a 10 pin Tag-Connect footprint - it is an off-the-shelf pogo-pin like connector ("Plug-Of-Nails TM") for adding debug / programming headers to devices without incurring the cost of the connector. TC2050-IDC is one of the connectors that will fit it. (Apologies if this ends up being double post - UA-cam appeared to eat initial comment, so had to re-post without link - google it!).
I’ve used them as well, they’re pretty nifty, for people who do consider using them I strongly recommend the locking style, it’s well worth the extra board space. Also double check the pin number order... The most interesting place I’ve seen them is on the NASA Ingenuity helicopter FPGA PCB!
Really nice stuff. I use the 6 and 10 pin version. But normally without the clip holes. You can find all the stuff here www.tag-connect.com/
They are nice but rather pricy! I would recommend the ones with the clips/legs, even if you lose board space. Using the push-on retainers for the non-legged version is a pain, really.
@@beanstone7 Yes, you need to be doing some reasonable volumes to make back the cost of the Tag Connect connectors - as small pin count connectors for programming purposes are pretty cheap if you use something ubiquitous.
Almost, except that the Tag-Connect uses three through-holes to align without risk of reversal, the footprint should not include solder paste on the pads.
I think this footprint looks more like a 1.27 or 2mm pitch boxed header...
Kensington lock in the Focusrite: it is used in schools a lot. That is why it is there.
Wish it was more common, costs approximately $0 to include & useful in many cases.
Music store owners also love Kensington locks on demo equipment, especially the smaller stuff.
@@everyhandletaken Yup, I'm adding it to my product it's 100% free, Kensington doesn't charge anything for it including the logo
Good point - my school had a lot of audio equipment in the music school - the only theft I heard of though was that kids stole RAM chips by pushing the 5.25 inch expansion panels out and pinching the RAM. Kids eh?
@@everyhandletaken "useful in many cases" not really, takes 2 seconds to pop open
The Scarlett Solo has the niche perk of fitting almost perfectly in a 5.25" bay.
What a useful feature in 2021 :D
lol I haven’t seen a 5.25” bay in a decade
I've had the Scarlett Solo for over a year. I use it with an AT2020 mic. I do online training with customers and they've been very appreciative of the audio quality. Sounds great outbound too through my AT cans.
Regarding the HPF (high pass filter) -- it is pretty common to have it done very early in the audio chain, definitely before A/D, and sometimes before the first gain stage. My analog mixer has a RC network with a BC309b to make up gain just after the input transformer and a discrete first gain stage with BC560b / BC239c -- very vintage!
Doing it early saves a lot of headroom and hassle later in the signal chain, so it makes sense.
Been waiting so long for a teardown of one of these interfaces by you!
Dave, if you're using windows check that the sample rate of the AI-1 is the same for both input and output audio devices. I have found that under Windows it can often change between sleep/reboot for whatever reason. When this happens the input (microphone) device doesn't work. It seems to be a Windows thing.
18 years ago or about I bought a M-Audio sound card, and I bought a breakout split mixer box for it. Can't use the card any more (old PCI) but the mixer box is still superb and running to this day. I opened it up and found it was entirely analog, the ADCs and DACs being on the PCI card and the construction is really well done. I still use it for its preamps and headphone amplifier. Great for uniting my spaghetti of an audio mess. I might buy a new audio interface one day if I get back into digital audio work, but i'd still use this lovely split mixer.
5:00 That thing is called a Tag Connect Programming / Debugging header. The holes are for clips that clamp the header down, so the designer can do programming/debugging.
Damn I've been looking for the name of this for ages, thanks!
A bit late to the discussion here, but I figured I'd mention this just in case no one else has mentioned it, although they probably have. Dave, a step up to the Fucusrite Scarlett 4i4 would meet your needs. It has a separate volume knob for the headphone output, and the monitor output level can be turned all the way down, leaving only the headphones operating. The 4i4 is the next model up from the 2i2, and it isn't much more in cost. I hope this is of some value.
I use Focal and ATC monitors for studio work. I also use Focal Clear open backs for listening to music. Focal makes great gear. But with regard to Focusrite, they make really high end studio gear as well of of the studio I record at uses their Ethernet audio based stuff and they seem to really love it.
The periodic noise on your audio signal is the old decabit ripple control signal leaking through your power supply.
I had the same reaction on the XMOS processor capabilities 6 years ago opening a 2i4 and 18i20 variant. It ca have 8-32 simple cores inside for parallel computing. A so called "tile processor". It's like a little brother to Cavium Octeon and Tilera CPUs. :) I was repairing it for a stage and sound engineering company hosting live performances and shows. The problems were only with the CD4066 Analog switch/mux. Sometimes those guys accidentally plugged in phantom powered stuff into it, backfeeding it. The switch/mux didn't appreciate it that much. :)
I always thought this was a Danish company based on the use of the Danish letter Ø in their name till you showed the made in Australia sticker, found this on Wikipedia: "Peter Freedman added the 'Ø' character as a salute to his Scandinavian heritage"
I'd need to check current models, but I think you can get the features you want like high pass filter and stuff on several MOTU interfaces, but every feature costs. The Focus Right Scarlet series is one of the best for cost effective pricing. Sad part is that the high pass is probably built into the DSP and all they needed was a button or two.
Wondering if Dave knows the trick with putting self tapping screws back. Spin them backwards until you get that slight click and then go forward so as not to cut a new thread. Short of over tightening cutting multiple threads is what gives them such a bad rep.
I do that with most every screw there is, both self tapping and machine screws. I hate cross threading and backing off until you feel it fall into the thread makes it next to impossible to get a cross thread. However it's most useful with self tapping, wood screws and when you have thread tapped into thin metal sheets like in a lot of computer cases. Just to make things "better" a lot of computer cases come with really bad screws where the thread is barely functional. These are notoriously easy to cross thread.
Yes, I've been saying that in my videos for years.
@@EEVblog Great to hear.
Kensington lock is useful in educational contexts, where the little darlings might fancy taking it home.
Let me guess, you never worked in education right?
I was curious about the CS4272 and its High pass filter option so I reached out to focusrite, here is what they had to say.
Note: Just for some context, I asked about potentially using the High Pass feature via modification of some kind.
Focusrite - "We operate the CS4272 converter with the ADC set to use “high-pass filter” not “DC Offset Calibration”.
This is non-switchable within our implementation and the high-pass filter in the CS4272 is not configurable. It is there to remove the DC offset from the drive circuitry just before the converter.
This is a standard Implementation used in AC coupled inputs (i.e. inputs that cannot support recording static DC voltages)."
A lot of more pro audio interfaces have Kensington locks, as they're very easy to pocket otherwise, and commonly used in areas with lots of transit.
Absolutely, a lot of stuff was being stolen at my Audio Design school.
I think the Kensington lock slot is most useful in school and institutional settings where they don't want opportunists simply walking off with their interfaces.
@@parentteachernight Yeah, at this school you could also 'book' studios to work on projects, so slipping something in your bag when alone in a studio would be real easy.
*(jack and xlr cables went 'missing' all the time too)
I wouldn't call Focusrite pro audio... more like prosumer audio
@@bitdevice exacly what consumer would need an 18i20
Love the videos and the knowledge you're sharing with us. Thank you Sr!!! BTW, I can't help to hear your voice in my head like an older version of Morty from the R&M. Sorry!!!
Nice comparison, looks like the Rode is slightly a cut above in all aspects. I would be very interested in a side-by-side with one of the cheap Behringer interfaces as well, specifically the UMC22 which tries to be a look-alike of these units. Apart from just having outdated, lower-spec components, it would be interesting to have a deeper dive into why exactly it's so cheap. I mean I have one and always found it got the job done, but I'm still curious about its shortcomings.
The “AIR” button is for when you play an air guitar…
unfortunately it makes no sound
595 in the focusrite is actually for the front panel I thought (and I have teared down mine). There are lots of function switches with only a 12pin connector.
Check out the Coilcraft inductor at the top! 19:12
The Rode just seems a lot better in design. I wouldn't be surprised if those are Alps potentiometers.
That's awesome! Thanks! I'd love to see some more codec stuff! Lately I've been working on a design to test an AD1937 because I would like a codec with 4 ADCs and a few DACs. Although the 8 DACs are a bit overkill for me, this together with the AD1939 was one of the few I could find stocked on mouser and available on LCSC as well. There is an experiment kit for these, but I find them a bit expensive and I just want to test the chip and whether I can get it to work with an STM32 nucleo. I'm trying to read and follow the datasheet as well as I can, but I don't understand everything about it. For instance the purpose of the loop filter. In the application circuits part it shows two configurations, apparently when using LRCLK or MCLK as PLL reference. What also confuses me is the placement of the crystal oscillator input and output lines, right in between the audio lines. Shouldn't that high frequency stuff kept far away from the audio part? It could well be I just picked a bad chip to get started with audio codec experiments and I'm aware there are some other options, but I'm quite new to this. Could you advise? Maybe you could make a video about audio codecs that goes a bit more in depth, explain some aspects of the input and output filters, turning differential into single ended, etc.. That would be amazing!
Yes I would keep it away!
Not surprised by this, Focusrite is a long-standing brand that's been a standard in professional studios for decades. Back in the day, the ISA series preamps and channel strips were a go to for us, and the Scarletts came out just as I was getting out. Even their consumer devices have always been excellent, as long as it's not the Green or Platinum Range. Rode is still really project studio/podcaster level, though we did use some of their mics for room mics.
The Focusrite was a Rupert Neve company. A huge name in the 1970s onwards for professional audio mixes.
XMOS was also founded by David May and a bunch of former EX Inmos guys to.. Which is why there micro controllers have an emphasis on using a cluster of multiple "micro cores" for high parallel processing.
for anyone actually wondering air usually refers to around 10kHz on the frequency spectrum, it's a little top end boost
It's so cool that you bought one with Mic and instrument input. Now you can play the banjo while talking over the videos.
You know what i had the same issue. The microphone was frequently dropping off. But its not the hardware . I fixed it permanently with simply changing a driver. I switched to asio driver which works better with sounds stuffs. Then boom it worked. Maybe u can try it too. And lastly i liked the way you showed the comparision between two. Cheers
min 4:55 it`s called Tag Connect
I've found that the Behringer UMC series (I have the 404) has the lowest noise floor of all the ones I've tried
I would love to see a RME interface teardown in comparison
I’ve recently torn down a RME UFX+ and it is quite sophisticated, maybe if there is enough interest I’ll make a video/blog/post pics about it!
yes please!
@@nudgeee My ufx+ power supply died twice until now. Probably dies because it's always on and then dies when it's turned off while hot.
@@nudgeee a Fireface teardown or blog would be appreciated!
Yes! Please more pro vs ‘pro’ gear
I have the focusrite and love it. Works great
Focusrite is fantastic for legacy support! I still use a FireWire 800 unit and focusrite went out of their way to test and validate the unit w a FW800 to Thunderbolt dongle.
I really suggest to check Steinberg UR12/UR22 audio interface too
I have owned two of those scarletts. The first was used, got it for cheap, it broke in a week (but worked fine before that, completely) because after a slight jostle one of the power bits on the PCB came loose and it was useless. I bought another one, new, and it's been working perfectly since.
Even with the odd adc in there, that Rode unit is really nice, stand up company you've got down there. Funny thing about the effects is starting to see that on some mid-higher-end units with dsp and full eq and gates. Can't wait till that makes it down to the sub 200 market!
They won't be polymer caps in the Rode. Low value wet SMT caps often don't have pressure relief indents. Polymers are not recommended for audio coupling because they have relatively high leakage currents. Top notch stuff like Neve uses tantalums for long life, although one has to be careful with distortion arising from their use.
Actually Nichicon "main stream" audio grade caps are not darn expensive nowadays and only needed in signal path.
Tants are pretty rare in audio these days. Ordinary electros meet 99% of applications, and when lower leakage is needed they just use two in series.
Yeah just normal electrolytics, a few Panasonic FK series.
XMOS jobbies are super common in audio interfaces because they come with a stable, pre-built/drop-in USB Audio 2.0 implementation
I've got a Focusrite 2i2 coming from amazon next week. I've used someone's 4i4 in the past so I decided to get a Focusrite myself.
212 second gen is a great unit 😀
Self-tapping screws into plastic really aren't a terrible idea in some applications. They are used in lieu of thread inserts in Fujitsu's Lifebook series of semi-rugged laptops due to issues associated with dislodging of inserts or cracking of the plastic around them.
Yeah, it's not that bad, I'm being a bit melodramatic.
@@EEVblog On a mountain bike drivetrain on other hand it's a disaster.
I am happy with my UR22C from Steinberg
The Motu M2 (or M4) is a top quality USB interface with a bar graph. It's an amazing device.
But currently unavailable over here in Europe 😢
Is it? I live in Europe (France), I bought one a year ago from Thomann.
Hi dave ...good enough to Australia..love from sri lanka...
That's a Tag Connect TC2050 debug port, quite common - look it up ;)
The probes themselves are ridiculously expensive, but the PCB footprint is basically free :P
I have the Focusrite. Never had any issues with it.
I have to add, that i successfully repaired a Focusrite Scarlett 3rd gen Sound card, on EEVBlog you guys identified the faulty part, (A DC step down chip, supersmall package) The customer service sent me replacement parts FOR FREE, and when i asked about delayed postage THEY SENT ME ANOTHER FEW CHIPS FOR FREE, and i was able to repair the unit. For me it says they care about us. Hands up for Focusrite. I know there are better sounding units outthere, but this experience was pleasant for me.
This might be a stupid question, but I don't get it:
Why does the Focusrithe need the Cirrus Audio Codec (CS4272), if the XMos processor has all these audio in- and outputs on it anyway?
As a musician, I'm very excited to see this tear down!
Agreed! Headphone amps are so useful and fun and easy to make and work on!
the motu m2 would be your best bet if you want the peak meters on your input and outputs.
The self tappers seem to screw into the metal grounding brackets on the rear panel, so the case is grounded through them. Seems a nice detail. Also, I did see some quad pin "L" component next to the USB power circuits?
Is Scarlett's volume knob in digital domain (using volume feature on DAC), or is a traditional audio potentiometer?
It's an analog pot.
And technically the Scarlett is a dual channel interface vs the single channel rode. The second channel on the focusrite is a line in with switchable Hi-Z Instrument.
Yeah, true.
The debug connector is a tag connect standard jtag interface, it's pretty usefull and removes a component.
Flies away
Check out E-Mu. Has all you want as has had for decade plus. Best sound card and interface ever! Even has mic pre amps and phantom power of -48vdc. So many interfaces on it.
holy shit balls this is educational. i am wanting to make my own interfaces and various stuff (because i dislike everything i can afford) and this is absolutely brilliant. i really needed this video. thanks mate.
About making one - you can get really fancy with the ADCs/DACs and with the expensive analog frontend stuff. The trouble lies with the USB to I2S chip. Aside from a venerable PCM2906 that is, which is easily available and needs no configuration, albeit with no volume control implemented and it does only 16bit/48kHz. I've heard people having success with programming an XMOS themselves (it involves meddling with the USB stack), but no solution I am aware of at a hobbyist level offers multichannel 24bit/192kHz I2S interfacing.
Happy x -Mos to you, Dave!
I’ve got both of these (but the dual not the solo) and have no issues with the Rode. My only complaint is that the Rode doesn’t have enough boost for the Rode Podmic and even the Focusrite has to be at max level for that mic.
I'm actually considering the Rode Podmic. Here shows the best pre amp is the MOTU M2 2x2 ua-cam.com/video/xLShpyzwvJs/v-deo.html
Oooo. This will interest me greatly! I've been hesitant to get one of these so let's see how this turns out!
The focuswrite for its price point is really good compact little interface used them alot, the dynamic range ceiling of the mic input is low for high impedance mics if you produce or record rock or metal and appropriate mics the focusrite Isa 1 is a better fit
Could you give me some advice on making the choice between NT1 4th with AI-1 SET and a single NT1 5th since the price of theses two are almost the same. Thank you!
Problems could be hum on USB ground. USB2 is not fully differential and needs solid ground. Often double shielded USB cables help.
Have you tried updating the bios on your pc and did you use a usb 3 port for the rode? If not those things could have fixed your connection problems
neat idea
@@AldoSchmedack It ain't just an idea its a solution which is probably gonna fix the problem
You've got more patience than I so, if I had to reshoot footage because my interface decided to eat glue, I'd be furious! I'd have hit it with HV and brought out the sledgehammer! I ain't avin' it!
I have gone "stuff it" and not bothered. Depends on the importance of the video.
Yeah, talk about annoying! As bad as a corrupt video segment.
Photon 👌👌
I had issues with the rode ai 1 when windows updated and changed the frequency in the advanced settings for the device. Switching it to 48khz makes it work perfectly
ah yes I had the same with a Zoom interfac. The issue is actually how Windows handles and sometimes unexpectedly changes this, deeply hidden in submenus. The interfaces themselves have little to do with this.
had the same issue. it was because the input was set to something like 24 khz and the output to 48 khz. because its on the same usb interface windows would completely freak and the device would act extremely erratic as it couldnt connect to it properly. making the same like you said fixed it. all because of a windows update.
I've had to fix that more than once.
can you explain the circuit of the fethed preamplifier ?
love all the test points on the Focusrite ..cool they are mostly through hole too... when it becomes obsolete could hack it for other uses.......after a recap that is! :P
I've had really good luck with Behringer UM-2's. I've gone through a pair of scarlett solos in the same time period, and the Behringer is about half the price.
the UM-2 is a third of the price of the Scarlett solo
I have a 204HD, excellent interface for the price, also have the new FLOW 8 which is also a great product though the bluetooth latency isn't great.
I'm also a fan of the UM-2 (or Behringer stuff in general; they're never the *best* but I've owned dozens of bits of their kit over the years and they've never let me down). The only real issue I have is that Behringer no longer supply drivers for it which can cause problems if you're using an application that doesn't have ASIO support and have to fall back on the generic WDDM driver -- Audacity sees it as a mono input, for example. (Thank god for Voicemeeter Banana!)
@@elbiggus Look on Gearspace, I uploaded the old 16bit Behringer driver which may work with the UM-2, it supports WIN10-x64 and works fine on my UFO-202, much better than using either ASIO4ALL or the built in windows driver.
I’d like to see testing of both to confirm their specifications and then possibly recap the focurite with high quality electrolytics (no audiophile snake oil, just high quality ones) and retest to show if any of the measurements change.
Have you tried an older firmware version ? I don't like updating firmware. Once I get something to work, I leave it.
I'd like to see the UMC22 compared with either if these. It's more than half the price and is pretty decent in terms of sound quality.
just send him one and i'm sure he will be happy to tear in down in the mailbag
Have you tested them on windows 11? Has the issue with the AI-1 been fixed? Was the unit faulty? Do you know the cause now?
I just saw a video showing how to fix weird sound. You go to line properties->switch to 44100 HZ on both playback and recording.Have you tried this? If so did it fix it?
It runs at 44100 Hz, so you have to make sure it's set at that.
Proud member of the 595 fan club checking in.
I had been having USB audio issues and I had thought it was a bad cable but swapping cables didn't work. My devices are externally powered and for a few days I couldn't figure out what was going on. But it all started after a windows update and ended a week later after another update and reboot. I think my issues had something to do with some system or USB port driver. I had different devices and different cables and still I had weird dropouts and robot voice playback issues. And now everything is perfect. Gremlins maybe?
the low cut thing, I follow a lot of automotive channels (first love drag racing, second love electronics) my god do they need a HPF on their mic inputs. wandering around pits at races, there are a LOT of horiffic low frequency noise sources. so, a thankyou for thinking full picture about us listeners.
You can really see it on the waveform view in editing when you bump the mic.
About highpass filters, you can just do that on your computer as well, even in real-time.
There are billions of solutions, I personally use Equalizer APO in Windows.
For non-live recordings, just dot it in post.
No. Don’t ! Overloading your input with low frequencies won’t be fixable in post. Always use a low cut at the input stage if the low frequencies are not needed. Just don’t overdo it ;)
@@rdoursenaud yes! obviously.
You need to do quite a lot to fully overload your input stage.
So do it! ;)
Debug connector looks pretty much like TagConnect spring loaded one with latches
Perfect voice for silent movies; perfect face for radio.
What's with the intermittent buzz?
Looks like the Scarlett has somewhat higher quality 6.35 mm jacks than the Rode. Those semi-open jobbies tend to be more reliable than the fully enclosed ones.
2:04 But you do have a radio voice, at least if we're going by early 1900s standards. Bassy voices didn't sound good on the tinny speakers and limited bandwidth they used back then, so all the best radio hosts - and singers - were tenors. Of course, by modern subwoofer and DSP-augmented standards, everyone on the radio needs to be a barytone, or at the very least utilize the proximity effect of their microphone for all that it's worth. But that's a story for another day.
What I don't get is that the Rode Interface seems to be using a STM32F070F6 for the USB interface, which does not feature a hardware I²S peripheral. The NAU88L25 uses I²S. Do they implement I²S in Software? Or do they implement it via the SPI peripheral?
I'd assume they do some trickery with the SPI interface (maybe a timer that creates the wordclock?). I was surprised that the F1 series does have native I2S but the F0 does not.
The focusrite has a decently noticable noise floor tho, which is why I sided with rode personally, since I didn't want to go too deep financially for a single input Audio-Interface. Would, since I didn't run into any issues with the AI-1 go for it 10/10 again.
Both of these interfaces are produced as low cost devices, if you want to see better quality interfaces look at RME, MOTU, Universal Audio or SSL prosumer/studio line interfaces
MOTU M2 would be a good comparable, plus it has bar graphs!
Focusrite does make some nicer units but the cost is outrageous.
4:02 - The Front Panel didn't fall off! :)
the Behringer U-Phoria UMC204HD is also a really good low priced unit i have had really good luck with gives you 2 channel for a bit less then the solo if someone needs 2 channel. i use the umc404hd 4 channel for 150$ and its great. i also have focusrite ones but i seem to grab the 404hd more often
YT is really annoying me right now it’s hiding many of my favourite creators like Dave. It did not show this in my list and I fell across it searching for Adobe premier tutorial. It’s like really WHT 🤦♂️
Can i use Rode AI-1 as an external sound card for PC windows 10 and will it require a driver?
Please Help
That op amp...OK I haven't looked for ages but it seemed the second bunch of numbers were so close to a 1458 or 4558 or similar I would never have looked for a 2122 and of course I would have got the same package details anyhow...and maybe never known.
I was having the same issues with my rode, It was resolved with a new USB type C cable
That didn't fix mine.
@@EEVblog , That was interesting! Thanks for including that observation!
The more I use them, the more im convinced the C connector is a crap design, seen so many dead Switches with gnd/vcc shorts (straight to the CPU, no protection) where the C connector is trashed, or oulus quest 2 where the socket has got so hot it's desoldered from the PCB. Trying to cram too many fine conductors into a thing that will be frequently unplugged is a recipe for disaster.
@@EEVblog Sorry to hear it. I got mine used from some kid who had apparently dropped it on it's USB C cable and it had the exact same issues that you were describing. Perhaps your connector is failing?
I am in the market of an audio interface (as well as a headworn microphone and open headphones, cables to go with) so I will watch your videos on the Scarlett. Which some recommended and some recommended not to buy. Always have this issue with shopping for audio stuff: people have a really strong reason against one product and I lose all my interest in it.
True focusrite is award winner but some people say ID4, ID14 IS better than focusrite 2i2. I am too confused which should I buy.
Just when I've been shopping for an audio interface! Thank ya!
Check out E-Mu too!
I have a 2i2 1st gen that served me well, then won a 2nd gen in a giveaway. Great interfaces! One had a headphone volume potentiometer go bad (scratchy, unbalanced volume) and I emailed them, explaining the issue and that I have some tech experience. They promptly sent me a replacement pot!
I love the static humming in the audio of this video while reviewing dedicated audio interfaces
How about doing a teardown of a Synology NAS?
I had an issue with the AI-1 (i guess it was a windows issue) that windows would randomly decide that the usb didn't need power anymore so it would drop out. there was setting in windows that is for power saving and it can power down usb devices, took me a while to figure that one out
EDIT: setting was call USB selective suspend in case anyone has the same thing going on
Is it that AMD USB bug?
@@EEVblog I don't believe so. It is an AMD system but the problem was just the windows power saving turning it off for me
I think you can change power management settings in device manager if this is the case :)
A gigabyte board can sometimes turn off my mouse and keyboard, so i needed a hard reset or PS2 kb
Done that with this model and mine cuts out and doesn't come back until I go to the Focusrite control panel and go: File>Restore Factory defaults. I've been onto support but so far it ain't any help. Think it's a faulty unit.
Enjoy your random crackling from the focusrite interface and it dieing the moment anything that produces a remote amount of EMI so much as looks at it. Me and many other friends that bought them experienced the exact same thing.
Ah you've also been experiencing issues with the AI-1? I bought one from a music shop, first one wouldn't show up on my computer, replacement has a horrid ground issue on the outputs.
Just starting. Really hoping he find/says something about the scarlett's broken direct monitor functionality.
Not a feature I'll ever use. How is it broken? I did actually try it once and it worked.
A few years ago I tried to play osmelloscope music through my old 2i2 (straight into my Tek 2225) and noticed some very high frequency noise (probably in the MHz range). NGL, I was a little disappointed, but to its credit there's zero _audible_ noise on the outputs and the scope music was sampled at 192kHz (my version is quite early, only goes up to 96), so it was never going to look right to begin with
Yeah, the CS4272 DAC famously has a lot of out-of-band noise >80 kHz (the essentially unfiltered output of the Behringer UMC202HD seems to fare particularly badly in this regard). It's quite an old design, I think it's basically the same as the standalone CS4392 first released in 2000. 5th-order delta-sigma, that's a lot of noise shaping.
