First owner, purchased in the fall of 2025.
Technically still under factory warranty till start of October.

Used at FOH for two Lukas Nelson tours since - in conjunction with a Yamaha DM7 console. I own a bunch of UA plug-ins and this was the ultimate chance to finally use them outside the studio. The unit is in excellent working condition. I added a thunderbolt 4 cable. No ethernet cables included. Will be shipped in the original box.

18 x 20 audio interface featuring Dante I/O plus, 2 x monitor out, plus AES-EBU I/O.
