A 2-channel USB audio interface with monitor level adjustment. - Model: SSL 2 - Connection Type: USB - Number of Channels: 2 - Monitor Level Adjustment: Yes - Headphone Output: Yes - Included Accessories: USB cable Purchased at Hard Off a few years ago, so no original accessories are included, only a TYPE-C cable. No plugins are included either. I think this is a good interface for portability. I used it with a Mac, but I don't know about Windows! Please Google it! Thank you for looking.
