A 16-input digital mixer with Wi-Fi connectivity, a USB port, and media playback functionality. I'm selling this because I've been primarily using the Ui12. I purchased it from Soundhouse and used it until recently. It's fully functional. It was kept in a rack, so there are no major scratches. The original box is included, but it has some damage. I will wrap the original box in packing material for shipping. Please ask any questions in the comments. Thank you for looking.
