This is an audio interface from Antelope Audio. Honestly, I think the sound quality is the best in its price range. It has a lot of inputs, so it's incredibly useful for band recordings and other recordings without a recording studio. I've used it for about 5 years, so the screws and other parts are dirty, but it works without any problems. The original box, power cable, and USB cable (type B to A) are included. It will be deactivated before shipping. The included software cannot be transferred due to its specifications.
