Interface on another level
lapsio, 18.04.2020
I have never in my life even remotely thought that interface can change my workflow this much. Integrated zero-latency hardware 1 bus mixer is game changer since... it works even if PC is turned off and interface is unplugged. It means that you can actually set this interface up in such way that when PC is off Scarlett 18i20 can behave as pass-through device passing any line-in of your choice (eg. inputs 7-8) directly to your main XLR monitors. It makes it really easy to connect multiple either balanced or unbalanced devices to monitors. Kinda like... monitor controller or actual mixer AND interface in one device.

Really nice. Value added by this device is simply incredible. Also it works under Linux (as of today there's kernel patch available on linuxmusicians fixing implicit USB feedback issue).

The only issue I have with this device it's that it has ONE bus mixer. Means you can create one "custom mix" aka virtual mixer (with whichever physical or software inputs you like) and then assign this one mix output it to whichever outputs you like but there's only ONE such stereo mix. It means that you can't for example pass line-in 7-8 to out 1-2 and line-in 5-6 to out 3-4 as that would require 2 independent virtual mixers which is not possible.

pros:
- standalone 1 bus mixer
- signal level meters and other back lit indicators look super dope
- 10 built-in output channels (a lot of devices have only 8). In general great i/o
- rubber caps to cover rack ears mounting holes if you don't use them
- kind of works with Linux as well as smartphones

cons:
- standalone ONE bus mixer
- i believe more controls should be exposed as physical buttons. Eg. AIR switch which is physical on some other Scarlett devices.

A PITA for Linux users
Mercs, 13.01.2021
While physically speaking the quality of this unit is great, the software implementation leaves a lot to be desired. Many configuration options, such as extending the number of inputs through the ADAT connection, require using the Focusrite Control proprietary software suite, which is only available for Windows and Mac. Why not make all options configurable without a PC, and especially without a proprietary piece of software?

This device desperately needs hardware controls for user settings. With that, all Focusrite would really need to do to provide Linux support is to make the device USB class compliant. Unfortunately, since the driver is proprietary, the Linux driver is a reverse-engineered one that works but still has some issues, the device being as new as it is. The free/open source community will fix the driver issues in time, and the device is already quite usable, but all the troulbe make one beg the question: why make things so difficult, Focusrite?

Otherwise, the device is fine. Lots of inputs right into your PC - what more can you ask for.

Currently looking for a negative
Benedict Entropic, 13.07.2021
I went from a 2i2 first-gen Focusrite to this beauty and was overwhelmed at how good this is!
Not quite "plug and play" as I had to download a driver but this is not an issue for me. I even got a little confused over software and the customer service on the Focusrite website were instantly helpful even at 3am in the morning.
I am really enamoured with the routing possibilities from the app and im looking forward to putting this unit to the test properly.

All-In-One
Bonzvy, 24.03.2021
Ich nutze den 18i20 3rd Gen schon seit längerem und habe keinerlei Beschwerden. Der Preamp ist für meine Ohren sehr transparent, die Haptik fühlt sich gut an. Ich verstehe das manche die "zu kleinen" Regler bemängeln, aber ich habe damit kein Problem. Das Interface bietet viele Erweiterungsmöglichkeiten, zu dem ich nicht viel sagen kann, da ich sie bis heute nicht verwenden musste. Verwenden tue ich das Interface primär in meinem Home Studio, wurde aber auch schon für kleiner Live Gigs eingesetzt.

Ich finde es sehr sinnvoll, dass es einen Talkback Mic integriert hat, jedoch muss man dafür das Interface direkt vor den Augen haben oder über die Focusrite Control bedienen. Zweiteres funktioniert zwar, aber dann ist man zu weit weg vom Talback Mic - also alles etwas semi optimal wenn man das Interface in einem Siderack verbaut hat.
