Behringer UMC404HD

!Update!
Bought it on 15.02.2021 - Stopped working on 05.11.2023.
No sound coming from headphones, no output from output ports, and inputs, not receiving any sound.

The unit does the job.
Sturdy metal casing, no loose potentiometers or knobs.

Headphones output volume potentiometer sometimes produces some very silent crackles when using it after some time untouched but after few tweaks volume up and down it just disappears and works well.

The headphone output produces lil' noise after pushed around 2 o'clock and the noise increases as you raise the volume. But it's only audible just listening to a sound card headphones output without playing any music. It's inaudible while listening yo music and I listen it around 11-12 o'clock position. You don't wan't to listen that loud anyway :) so no big problem here.

All jack input slots are sturdy. Have not tried RCA outputs but I guess they work as usual.

Connected some outboard gear to process my sounds. Latency is really low only few ms using Reaper via reaInsert or just sending sound via send to hardware and back to soundcard.

Good unit, cheap, use it everyday and no big problems to date.

Don't buy this piece of junk under any circumstances! If you run a Mac you may be OK. You get double the spec of the competition for the same money and it feels like a solid piece of kit. However, there are problems with the Windows drivers and this is not a secret, just Google it and see. I have spent 90% of my time messing about and almost no time recording. I need to record at 44.1hz to match sound files I have but the Behringer will not adjust (or if it does it quickly flips back). It defaults to 98hz. There is no adjustment in the control panel. If you try and do it from the DAW it has no effect (it just says your sample rate is not supported). If you do it from Windows controls it either works for a short time (and then reverts) or it has no effect. I am at my wits end. I have wasted hours on this problem as well as my money. It's been an issue for some time and Behringer haven't sorted it. If you want to spend your leisure time troubleshooting buy this! If you want to record buy something else. I'm VERY unhappy with this purchase.

Items feels well built, good weight, solid connectors. All was very promising but after 5 hours I just couldn't get it to work with Windows 7. My operating system wouldn't recognise/accept the digital signiture of one of the driver files. Complete and utter standstill. Thomann were poor with their support, in particular their Studio dept. In the end I was offered and accepted a return and refund. Disappointing because the unit looks and feels very very good for the price. I would actually buy it again without hesitation if I ever update my OS. I've read that the problem is common to computers running Windows 7 and earlier.

...where should I begin?... well, I honestly believe Behringer should start taking care of quality and performance and not so much on ADVERTISING which seem to be the silver lining here for them. I have tried several of their Audio Interfaces (two of them from Thomann) and my luck has been nothing but terrible with both of them two devices... the noise, hum and hiss coming out of them is just unbearable. I tried different cables, monitors, laptops, Macs and PCs because I really like the little device but man... this a NO GO... the noise was just there like a bad infection and the solution was just to send it back and go with something else. The volume was low (headphones and output)... I produce Techno and Hip-Hop so believe me when I tell you that my setup is ready for noise and THUMP! lol... anyways, this is my personal experience, just my two cents.
