This item has only been taken out once. There are only very slight scuffs around the encoder, and I believe it is in beautiful condition. Input/output has been checked. I was unable to check the LAN port as I do not have the necessary equipment. The firmware is up to date. I am also selling a Decksaver. If you purchase this as well, I will offer a discount. I don't think this mixer is very well-known, but the sound quality is good and it's easy to use. There is a filter knob for each channel, separate from the seeep fx encoder. This is really easy to use. I think it has a design that is easy to get used to, even for those familiar with Pioneer. Thank you.
