The Scarlett 18i20 (3rd Gen) by Focusrite is their third iteration of this phenomenally successful series. And with each generation, Focusrite seems to iron out any flaws and add functionality.

It is an 18 input unit, with 8 XLR/TRS combination inputs, as well as a MIDI, S/PDIF and ADAT inputs/outputs.

The reason that this interface features two sets of ADAT inputs/outputs as it requires both sets to be used simultaneously when running the unit at 96kHz.

The unit itself is very physically pleasing, and can be rack-mounted. It also includes a range of software, which will delight any musicians who may be starting out.

As for the technical capabilities of the unit, as expected, it can provide a 192kHz sample rate, which is very impressive.

Overall, since it’s extremely new, there are few customer reviews in existence. However, when taking into account the previous versions and their customer reviews, it definitely suggests that this is an interface to look at.
