This is is a Clarett+ 2Pre (ie the very latest version of the 2Pre), great upgrade if you've been recording for a few years. ADAT in and out, so you can even add another channel strip for up to 8 more channels.
Comes with everything you need of course, box contents as per new. You'll also be able to register the unit in order to receive the optional free software/plugins etc. The 2Pre is great because you can also bus-power it if you're running a USB-C Mac Book, no power adapter needed (although that is included of course). Perfect working order of course, couple of marks on top and that's it.
