Behringer MONITOR 2 USB. It's a beautiful item and fully functional. Please forgive any minor imperfections as it is a used item. I used it for audio purposes for a while. Considering the price, I think the performance and sound quality are amazing. I also think it's an excellent machine as a monitor controller. I bought it new about two years ago. It's from a completely smoke-free, pet-free environment, and was only used in a dedicated room. Please consider this opportunity.
