Introducing an audio interface designed specifically for DJs. The AUDIO8.DJ boasts high-end sound quality, exceptional connectivity, and a rugged, mobile design. This hardware is the heart of any DJ setup. The AUDIO8.DJ is a professional-level interface that bridges the gap between software and the audience. It's a must-have for DJs who are serious about their sound. I received this from a friend, so I'm not familiar with all its functions. I confirmed that sound comes out of the speakers via USB input, and I also confirmed that the level gauge in the bottom right lights up according to the input signal strength, but I haven't tested any other functions. Accessories include two DVDs and a black bag. Please understand that this is a used item and carefully review the photos before purchasing.
